Description

Short link generation method and related equipment

Technical Field

The present disclosure relates to the field of computer technologies, and in particular, to a short link generation method and related devices.

Background

With the rapid development of information technology, two-dimensional codes, short messages, and APP message pushing all start to refer to technologies that jump to a corresponding long link address to access the corresponding long link address by accessing the short link address. This technique was developed for the following reasons: because the length of the recorded information of the two-dimensional code is limited, the longer the recorded information is, the lower the identification rate of the two-dimensional code is, so that the identification difficulty of the two-dimensional code is increased by recording a long link address through the two-dimensional code; if a long-chain address is added in the short message, the short message provider can automatically split the short message into two short messages, and the short message cost is changed into the cost of the two short messages, so that the short message cost of a user is increased; similarly, the APP application generally limits the content released within a certain word number range, and if the content exceeds the word number range, the content will be intercepted by the platform, that is, when the content released includes a long link address, the content released may fail to release due to excessive word number. In addition, the long link address may also impair the overall performance of the server, such as may affect the length of the long connection time of the server, thereby directly affecting the concurrency number of the server.

In general, long link addresses may be converted to short link addresses by: the user uses the terminal equipment to request the server to convert a certain long-link address, and after the server receives the long-link address, the server can select one short-link address from a plurality of short-link addresses configured by a developer in advance and return the short-link address to the user. However, this short link address translation is not flexible enough and there may be cases where the short link address returned to the user is already occupied by other long link addresses, resulting in the short link address being unavailable.

The following describes a short link generation system provided in the embodiments of the present application with an electronic device as a server. The short link generation scheme described in the embodiments of the present application may be implemented by the short link generation system shown in fig. 1. The short link generation system shown in fig. 1 includes a terminal device 101 and a server 102. The terminal device 101 may be in communication connection with the server 102. The terminal device 101 may receive a target long link address to be converted and a short link conversion policy set for the target long link address, which are configured by a user, and send a long link conversion request to the server 102, where the long link conversion request carries the target long link address and the short link conversion policy; the server 102 may process the target long link address to obtain a corresponding first short link brief code set, and generate a target short link address according to the first short link brief code set, and send the target short link address to the terminal device 101. Specifically: the server 102 may respond to the long link conversion request submitted by the terminal device 101, obtain a target long link address and a short link conversion policy carried by the long link conversion request, generate a first short link brief code set corresponding to the target long link address according to the short link conversion policy, traverse the second short link brief code set to determine whether the second short link brief code set has a target short link brief code in the first short link brief code set, generate a target short link address including the target short link brief code when the second short link brief code set does not have the target short link brief code, and output the target short link address through the terminal device 101.

Embodiments of the present application may relate to blockchain techniques, such as writing target long link addresses and target short link addresses into a blockchain.

Referring to fig. 2, fig. 2 is a flowchart of a short link generation method according to an embodiment of the present application, where the method specifically includes the following steps:

s201, the electronic equipment responds to a long-link conversion request submitted by the terminal equipment to acquire a target long-link address to be converted carried by the long-link conversion request and a short-link conversion strategy set for the target long-link address, wherein the short-link conversion strategy comprises a short-link generation mode and a short-link constraint condition corresponding to the short-link generation mode.

In this embodiment of the present invention, after a user may configure a target long link address and a short link conversion policy set for the target long link address based on a visual interface displayed by a terminal device, for example, a short link generation interface, the user may trigger the terminal device to submit a long link conversion request to an electronic device, and the electronic device may respond to the long link conversion request submitted by the terminal device to obtain a target long link address to be converted and a short link conversion policy set for the target long link address, where the short link conversion policy includes a short link generation manner and a short link constraint condition corresponding to the short link generation manner.

The short link conversion strategy comprises a short link generation mode and short link constraint conditions corresponding to the short link generation mode, and specifically: the short link generation mode can be a random generation mode or a custom generation mode, and different short link generation modes correspond to different short link constraint conditions. When the short link generation mode is a random generation mode, the corresponding short link constraint condition comprises at least one of the following: the character set type, the character set length and the encryption mode can be one of the short link constraint conditions, the combination of any two short link constraint conditions or all the short link constraint conditions. When the short link generation mode is a custom generation mode, the short link constraint condition comprises a specified character string. It should be noted that when the short link generation mode is a random generation mode, when only one or two of the short link generation modes are selected, the constraint condition is not selected to perform default setting.

Wherein, the character set category can be any of the following: pure digits (corresponding digits may be all digits of 0-9), pure lowercase letters (corresponding lowercase letters may be all lowercase letters of a-Z), pure uppercase letters (corresponding uppercase letters may be all uppercase letters of a-Z), combinations of digits and lowercase letters, combinations of digits and uppercase letters, combinations of lowercase letters, and combinations of digits and lowercase letters. The character set length may be a length value within a predetermined length range (e.g., 4-16). The encryption mode may be a mode of encrypting the universal unique identification code Universally Unique Identifier, UUID) or a mode of encrypting the MD5, which is not limited in the embodiment of the present application. In an application scenario, after selecting a random generation mode by using a terminal device, a user may set a short link constraint condition on a short link generation interface displayed by the terminal device. If the user does not select the character set length and encryption mode, the character set length may be a default character set length, such as 6. The encryption mode can adopt a default encryption mode, such as a UUID encryption mode.

S202, the electronic equipment generates a first short link brief code set corresponding to the target long link address according to a short link conversion strategy, wherein the first short link brief code set comprises one or more candidate short link brief codes.

In one possible implementation, when the short link generation manner is a random generation manner, the corresponding first short link brief code set may include a plurality of candidate short link brief codes, for example, may include 4 or more candidate short link brief codes. When the short link generation mode is a custom generation mode, the corresponding first short link brief code set may include a candidate short link brief code, for example, may include obtaining the candidate short link brief code according to the specified character string.

In one possible implementation manner, when the short link generation manner is a random generation manner and the corresponding short link constraint condition includes a character set type, the process of generating, by the electronic device, the first short link brevity code set corresponding to the target long link address according to the short link conversion policy may determine a target character set corresponding to the character set type for the electronic device, select a plurality of groups of characters from the target character set, and construct a candidate short link brevity code corresponding to the group of characters by using each group of characters. For example, the character set category includes a combination of digits and lowercase letters, the target character set corresponding to the character set category includes all digits from 0 to 9 and all lowercase letters of a-z, the electronic device may select a group of characters from the target character set at a time, such as selecting a first number of digits from all digits from 0 to 9 and selecting a second number of lowercase letters from all lowercase letters of a-z, and construct the candidate short-link shorthand code of the present time using the first number of digits and the second number of lowercase letters. In one embodiment, the electronic device selects a plurality of groups of characters from the target character set, and the electronic device may select a plurality of groups of characters from the target character set according to a default character set length, where the length of each group of characters is the default character set length.

In one possible implementation manner, when the short link generation manner is a random generation manner and the corresponding short link constraint condition includes a character set type, the process of generating, by the electronic device, the first short link brief code set corresponding to the target long link address according to the short link conversion policy may encrypt the target long link by using a default encryption manner for the electronic device, to obtain a first encrypted string, select multiple groups of characters from the first encrypted string, and construct a candidate short link brief code corresponding to the group of characters by using each group of characters. In one embodiment, the electronic device selects a plurality of groups of characters from the first encrypted character string, and may select a plurality of groups of characters from the first encrypted character string according to a default character set length for the electronic device.

In one possible implementation manner, when the short link generation manner is a random generation manner and the corresponding short link constraint condition includes a character set length, the process of generating, by the electronic device, the first short link brief code set corresponding to the target long link address according to the short link conversion policy may determine a target character set corresponding to a default character set type for the electronic device, select a plurality of groups of characters from the target character set according to the character set length, and construct a candidate short link brief code corresponding to the group of characters by using each group of characters, where the length of the candidate short link brief code is the character set length. For example, the character set category includes a combination of numbers and lowercase letters, the target character set corresponding to the character set category includes all numbers from 0-9 and all lowercase letters of a-z, and the electronic device may select a group of characters at a time based on the character set length. If the character set length is 6, the electronic device selects a first number of digits, such as 4 digits, from all digits 0-9 and a second number of digits, such as 2 lower case letters, from all lower case letters of a-z. The electronic device may construct a candidate short-link shortcode of this time using the 4 digits and the 2 lower case letters, where the length of the candidate short-link shortcode is 6. In one embodiment, when the short link constraint does not include a character set length, the electronic device may select multiple sets of characters from the target character set according to a default character set length.

In one possible implementation manner, when the short link generation manner is a random generation manner and the corresponding short link constraint condition includes a character set length, the electronic device may encrypt the target long link address according to the short link conversion policy in the process of generating the first short link brief code set corresponding to the target long link address by the electronic device, to obtain a first encrypted character string, select multiple groups of characters from the first encrypted character string according to a default character set type and the character set length, and construct a candidate short link brief code corresponding to the group of characters by using each group of characters, where the length of the candidate short link brief code is the character set length.

In a possible implementation manner, when the short link generation manner is a random generation manner and the corresponding short link constraint condition includes an encryption manner, the electronic device may encrypt the target long link address by using the encryption manner in a process of generating the first short link brief code set corresponding to the target long link address according to the short link conversion policy by using the electronic device to obtain a second encrypted string (the second encrypted string is used for distinguishing between encrypting the target long link address by using a default encryption manner to obtain the first encrypted string here), and select multiple groups of characters from the encrypted string according to a default character set type and/or a default character set length, and construct a candidate short link brief code corresponding to each group of characters according to each group of characters. For example, the default character set length is 4, and the electronic device may randomly select 4 characters from the encrypted character string each time as a group of characters to construct the candidate short link brevity code of this time. For another example, when the default character string is a combination of digits and lowercase letters, the electronic device may select a group of characters from the encrypted character string each time, for example, selecting a first number of digits and selecting a second number of lowercase letters to construct a candidate short-link brevity code of the present time. For another example, when the default character set type is a combination of numbers and lower case letters and the default character set length is 4, the electronic device may select a group of character strings from the encrypted character strings each time according to the default character set type and the default character set length, for example, select a first number of numbers and select a second number of lower case letters to construct a candidate short link brevity code of this time, and at this time, the length of the candidate short link brevity code is 4.

In one possible implementation manner, when the short link generation manner is a random generation manner and the corresponding short link constraint condition includes a character set type and a character set length, the process of generating, by the electronic device, the first short link brief code set corresponding to the target long link address according to the short link conversion policy may determine a target character set corresponding to the character set type for the electronic device, select a plurality of groups of characters from the target character set according to the character set length, and construct a candidate short link brief code corresponding to the group of characters by using each group of characters. For example, the character set type includes a combination of digits and lowercase letters, the target character set corresponding to the character set type includes all digits from 0 to 9 and all lowercase letters of a-z, the character set length is 6, the electronic device may select a group of characters from the target character set at a time, such as selecting a first number of digits from 0 to 9 and selecting a second number of lowercase letters from all lowercase letters of a-z, and construct a candidate short-link shortcode of this time using the first number of digits and the second number of lowercase letters, the group of characters has a length of 6, a sum of the first number and the second number of digits is 6, and the candidate short-link shortcode has a length of 6.

In one possible implementation manner, when the short link generation manner is a random generation manner and the corresponding short link constraint condition includes a character set type and a character set length, the process of generating, by the electronic device, the first short link brief code set corresponding to the target long link address according to the short link conversion policy may encrypt the target long link by the electronic device according to a default encryption manner to obtain a first encrypted character string, determine the character set type and the character set length, select a plurality of groups of characters from the first encrypted characters, and construct a candidate short link brief code corresponding to the group of characters by using each group of characters.

In one possible implementation manner, when the short link generation manner is a random generation manner and the corresponding short link constraint condition includes a character set type, a character set length and an encryption manner, the process of generating, by the electronic device, the first short link brief code set corresponding to the target long link address according to the short link conversion policy may encrypt the target long link address according to the encryption manner by the electronic device to obtain a second encrypted character string, and select a plurality of groups of characters from the second encrypted character string according to the character set type and the character set length, and construct the candidate short link brief code corresponding to the group of characters by using each group of characters.

S203, the electronic device traverses the second short link brief code set to determine whether a target short link brief code in the first short link brief code set exists in the second short link brief code set, wherein the target short link brief code is any candidate short link brief code in the first short link brief code set, and the second short link brief code set comprises one or more short link brief codes which are used.

Wherein the second short-link brevity code set may include one or more short-link brevity codes that have been used, and the short-link brevity code already has a long-link address corresponding to the short-link brevity code. In one embodiment, the short link profile in the second set of short link profiles may be time-efficient. For example, if the time of setting a short link profile in the second set of short link profiles is within 1 month, then after one month the short link profile will be cleaned up and will not appear in the second set of short link profiles.

In one possible implementation manner, the electronic device traverses the second short link brief code set to determine whether the target short link brief code in the first short link brief code set exists in the second short link brief code set, specifically: the electronic device traverses each short link brief code in the first short link brief code set in sequence in the second short link brief code set to determine whether a target short link brief code in the first short link brief code set exists in the second short link brief code set. For example, if the 1 st short link short code in the first short link short code set exists in the second short link short code set, the 2 nd short link short code in the first short link short code set is used for traversing until a short link short code in the first short link short code set is regarded as the target short link short code when the short link short code in the first short link short code set does not exist in the second short link short code set. In one possible implementation manner, the electronic device may traverse each short link brief code in the first short link brief code set in the second short link brief code set at the same time in addition to the above sequential traversing manner, so as to determine whether the second short link brief code set has the target short link brief code in the first short link brief code set. If it is determined that a plurality of target short link brevity codes exist in the first short link brevity code set in the second short link brevity code set, one target short link brevity code of the plurality of target short link brevity codes is randomly selected, so that a target short link address including the randomly selected target short link brevity code is generated.

Further, if all short link shortcodes in the first short link shortcode exist in the second short link shortcode set, repeating the steps S202 to S203, thereby determining the target short link shortcode. This is typically a small probability event.

S204, when the second short link brief code set does not have the target short link brief code, the electronic equipment generates a target short link address comprising the target short link brief code, and outputs the target short link address through the terminal equipment.

After the electronic device obtains the target short link address, the target short link address may be sent to the terminal device for output. The related equipment can realize the access process of the target long-chain link address by means of the target short-chain link address. For example, the terminal device or the user device may initiate an access request to the target short link address to the server, and when the server detects the access request to the target short link address, the server may query the target long link address corresponding to the target short link address, and implement an access procedure to the target long link address.

In one possible implementation, the generating, by the electronic device, the target short link address including the target short link brevity code may specifically be: and performing splicing processing on the target short link brief code and the preset character to obtain a target short link address comprising the target short link brief code. In one embodiment, the preset characters may include characters of a protocol portion and characters of an IP address portion (or domain name portion). For example, the preset character may be http:// IP address 1/, and the target short link brevity code is abddf, and then the target short link brevity code and the preset character may be spliced to obtain the target short link address including the target short link brevity code abddf: http:// IP address 1/abddf.

In one possible implementation manner, when the second short link brief code set does not have the target short link brief code, the electronic device may record a corresponding relationship between the target short link brief code and the corresponding target long link address, or record a corresponding relationship between the target short link address and the target long link address, so that the related device may successfully access the target long link address through the target short link address. Meanwhile, when the second short link brief code set does not have the target short link brief code, the electronic device may further add the target short link brief code to the second short link brief code set to identify that the target short link brief code has been used.

In one possible implementation manner, when the second short link brief code set does not have the target short link brief code, the electronic device may further record a corresponding relationship between the target short link brief code, the target long link address, and the IP address of the terminal device, or record a corresponding relationship between the target short link address, the target long link address, and the IP address of the terminal device. The correspondence may be used for access control to the terminal device. For example, whether the terminal device has malicious access behaviors can be monitored according to the corresponding relationship, the malicious access behaviors can be behaviors of continuously sending long-chain conversion requests aiming at the same long-chain address, and if the malicious access behaviors are monitored, the electronic device can refuse to process the long-chain conversion requests submitted by the terminal device.

In one possible implementation manner, when the electronic device is a server, and when other systems want to use the short-link generation method of the present application, an acquisition request for the short-link generation interface may be initiated, where the request carries an APPID and a token, and the server may return the short-link interface to the other systems after checking the APPID and the token.

In this embodiment, an electronic device responds to a long link conversion request submitted by a terminal device, obtains a target long link address to be converted and a short link conversion policy set for the target long link address, which are carried by the long link conversion request, and generates a first short link brief code set corresponding to the target long link address according to the short link conversion policy, and at the same time, traverses a second short link brief code set to determine whether the second short link brief code set has a target short link brief code in the first short link brief code set, and generates a target short link address including the target short link brief code when the second short link brief code set does not have the target short link brief code.

Referring to fig. 3, fig. 3 is a flowchart of another short link generation method provided in the embodiment of the present application, where the flowchart mainly illustrates specific flow steps corresponding to a short link generation mode being a random generation mode, and may specifically include:

s301, the electronic equipment responds to a long-link conversion request submitted by the terminal equipment to obtain a target long-link address to be converted carried by the long-link conversion request and a short-link conversion strategy set for the target long-link address, wherein a short-link generation mode corresponding to the short-link conversion strategy is a random generation mode, and the short-link constraint conditions comprise character set types, character set lengths and encryption modes.

The short link constraint conditions in the embodiment of the present application include a character set type, a character set length, and an encryption mode. In some possible embodiments, the short link constraint may include only one or a combination of any two. For example, when the short link constraint is a character set type, there is a default character set length and a default encryption mode; when the short link constraint condition is character set length, a default encryption mode exists, and the character set type can be set by default; when the short link constraint condition is the character set type and the character set length, a corresponding default encryption mode exists. The default values of the character set types, the default values of the character set lengths and the default values of the encryption modes can be set by a developer independently, and are not limited in the embodiment of the application.

S302, the electronic equipment encrypts the target long link address according to an encryption mode to obtain encrypted data.

The encryption method may be a UUID encryption method, an MD5 encryption method, or the like.

S303, the electronic equipment splits the encrypted data to obtain a preset number of character strings.

The preset number of character strings may be used to generate a preset number of candidate short link brevity codes, where the length of each of the preset number of character strings may be the same. For example, the encrypted data is a 32-bit string, and the electronic device may split the encrypted data to obtain 4 8-bit strings.

S304, the electronic equipment determines a data subscript range corresponding to the character set type according to the character set type, determines a displacement step length according to the character set length, and the character set length is n.

In one possible implementation, the electronic device determines a range of data subscripts corresponding to the character set category according to the character set category. For example, when the character set type is a pure number, the electronic device may determine that the range of the data index corresponding to the pure number is 0 to 9, when the character set type is a pure lowercase letter, the electronic device may determine that the range of the corresponding data index is 10 to 35, and when the character set type is a pure uppercase letter, the electronic device may determine that the range of the corresponding data index is 36 to 61.

In one possible implementation manner, the electronic device determines a displacement step according to the character set length, and specifically, the electronic device may determine the quotient of the binary number of the character string and the character set length as the displacement step. Assuming that the character set length is 4, the character string is an 8-bit character string, and the number of bits of the 8-bit character string is 32 bits, the corresponding displacement step may be 32/4=8. It should be noted that in some cases, the electronic device may have a remainder by the quotient of the binary digits of the character string and the character set length, so the displacement step may be determined by rounding down the quotient. For example, a character set length of 5, a quotient of 32/5=6.4, and the electronic device rounds down the 6.4, the displacement step size of 6 can be obtained. In some possible embodiments, the displacement step may be determined by rounding up, which is not described in detail in this embodiment of the present application.

S305, the electronic equipment determines a first bit character of a short-link brevity code corresponding to a target character string according to a target data index corresponding to a data index range and the target character string in the preset number of character strings, wherein the target character string is any character string in the preset number of character strings.

In one possible implementation manner, the electronic device performs an and operation on a target data subscript corresponding to the data subscript range and a target character string in a preset number of character strings to obtain a first operation result, and determines a first bit character of a short link brevity code corresponding to the target character string according to the first operation result. For example, when the character set category is a pure number, the target data index corresponding to the range of data indices may be 9,

In one possible implementation manner, the process of performing an and operation on the target data subscript corresponding to the data subscript range and the target character string in the preset number of character strings by the electronic device to obtain the first operation result may be: and the electronic equipment performs AND operation on the target data subscript corresponding to the data subscript range and the target character string to obtain a first operation result. In one embodiment, the electronic device performs an and operation on the target data subscript corresponding to the data subscript range and the target character string in the preset number of character strings, so as to obtain a first operation result, which may be: the electronic equipment converts the target character string into a decimal number, then calculates a first binary number corresponding to a target data index corresponding to the data index range and a second binary number corresponding to the decimal number, and then performs AND operation on the first binary number and the second binary number to obtain a first operation result.

In one possible implementation manner, the process of determining, by the electronic device, the first bit character of the short-link shortcode corresponding to the target character string according to the first operation result may determine, by the electronic device, the first operation result as a first data index, determine, according to a correspondence between the data index and the character, the character corresponding to the first data index, and determine, by the electronic device, the character corresponding to the first data index as the first bit character of the short-link shortcode corresponding to the target character string.

In one embodiment, when the character set is a pure lowercase letter, the target data index corresponding to the data index range may be 25 (35-10), and correspondingly, (the first operation result+10) may be the first character of the short-link brevity code corresponding to the target character string. When the character set category is a pure lowercase letter, the target data index corresponding to the range of data indices may be 25 (61-36). Accordingly, the character corresponding to (the first operation result +36) may be the first character of the short link brevity code corresponding to the target character string. When the character set type is a combination (a combination of a number and a lower case letter, a combination of a number and a upper case letter, or a combination of a number and a lower case letter), the electronic device may perform an and operation with the target character string by using the corresponding target data subscript according to the type (e.g., the number, the lower case letter, or the upper case letter) of the first character when generating the first character of the short-link shorthand corresponding to the target character string, so as to obtain a first operation result. Accordingly, the character corresponding to the m+1 operation result can be used as the m+1 bit character. When generating the (m+1) -th bit character of the short link brevity code corresponding to the target character string, the electronic device performs AND operation on the corresponding target data subscript and the (m) -th shift data according to the type (such as number, lowercase letter or uppercase letter) of the (m+1) -th bit character to obtain an (m+1) -th operation result. Accordingly, the character corresponding to the m+1 operation result can be used as the m+1 character.

S306, the electronic equipment acquires m shift data corresponding to the target character string according to the shift step length, wherein m is an integer which is more than 0 and less than n.

In one possible implementation manner, after determining the displacement step length according to the character set length, the electronic device performs a corresponding displacement operation on the selected target character string according to the displacement step length, so as to obtain corresponding mth displacement data. Specifically, when m is equal to 1, first shift data corresponding to the target character string is obtained according to the shift step length, and when m is greater than 1, shift data corresponding to the (m-1) -th shift data is obtained according to the shift step length and is used as the m-th shift data corresponding to the target character string.

And then, the electronic equipment can carry out shift processing on the first shift data according to the shift step length to obtain a fourth binary number, then convert the fourth binary number into hexadecimal number as second shift data corresponding to the target character string, and the like until all shift data corresponding to the target character string are obtained.

In one possible implementation manner, after the electronic device converts the target character string into a decimal number, then calculates a first binary number corresponding to a target data subscript included in the data subscript range and a second binary number corresponding to the decimal number, then performs an and operation on the first binary number and the second binary number to obtain a first operation result, the electronic device can perform a shift process on the second binary number according to a displacement step length to obtain first shift data corresponding to a third binary number serving as the target character string. And then, the electronic equipment can carry out shift processing on the first shift data according to the shift step length to obtain a fourth binary number as second shift data corresponding to the target character string, and the like until all shift data corresponding to the target character string are obtained.

S307, the electronic device determines the (m+1) -th bit character of the short link brevity code corresponding to the target character string according to the target data subscript and the (m) -th shift data.

In one possible implementation manner, the electronic device performs an and operation on the target data subscript and the mth shift data to obtain an mth+1 operation result, and determines an mth+1 bit character of the short link brevity code corresponding to the target character string according to the mth+1 operation result. The method for determining, by the electronic device, the m+1st character of the short link brevity code corresponding to the target character string according to the m+1st operation result may refer to the method for determining, by the electronic device, the 1 st character of the short link brevity code corresponding to the target character string according to the 1 st operation result, which is not described in detail in this embodiment of the present application.

For example, after the first bit character of the short-link brevity code corresponding to the target character string is obtained, determining first shift data according to the shift step length, performing an AND operation on the first shift data and the target data subscript to obtain a second operation result, and determining the second operation result as the second bit character of the short-link brevity code corresponding to the target character string according to the corresponding relation between the data subscript and the character. And similarly, obtaining all characters of the short-link brief code corresponding to the target character string, and forming the short-link brief code corresponding to the target character string according to the sequence of all the characters.

S308, the electronic equipment determines short link brief codes corresponding to the target character strings as candidate short link brief codes, and constructs a first short link brief code set comprising the candidate short link brief codes.

In one possible implementation manner, the character string obtained by encrypting the target long-link address is split into a preset number of character strings, and correspondingly, according to the method, a preset number of candidate short-link brevity codes are obtained, so that the first short-link brevity code set is constructed by the preset number of candidate short-link brevity codes.

S309, the electronic device traverses the second short link brevity code set to determine whether a target short link brevity code in the first short link brevity code set exists in the second short link brevity code set, wherein the target short link brevity code is any candidate short link brevity code in the first short link brevity code set, and the second short link brevity code set comprises one or more short link brevity codes which are used.

And S310, when the second short link brief code set does not have the target short link brief code, the electronic equipment generates a target short link address comprising the target short link brief code and outputs the target short link address through the terminal equipment.

Step S309 to step S310 are identical to step S203 to step S204, and will not be described in detail here.
