Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.
The embodiment of the application provides a data compression method, a data compression device, a storage medium and a mobile terminal.
As shown in fig. 1, fig. 1 is a flow chart of a data compression method provided by an embodiment of the present application, where the data compression method is applied to a mobile terminal, and the mobile terminal may be a smart phone with a KaiOS system, and the specific flow may be as follows:
s101, acquiring a log compression request, wherein the log compression request carries a file identifier of a log file to be compressed.
The compression triggering widget can be provided without having a compression function, and when a user starts the widget, a log compression request can be generated by clicking a designated key on a widget display interface, or a log compression request can be generated by selecting a compression key from a right-key menu after selecting a log file to be compressed. The log file to be compressed may be a single file, such as a text file with a single suffix extension log, or a folder, such as a folder including a plurality of log files. The file identity may be a file storage address for distinguishing between different files.
S102, calling a system attribute control component to set a preset system parameter to a preset value according to the log compression request, so that the mobile terminal starts a compression component according to the preset value.
The system attribute control component may be a component provided for a system initialization service, and the preset system parameter is a persistence.sys.kaioscompres.enable parameter in a system initialization file, and the preset value may be set manually, for example, 1. When the value of the persist.sys.kaioscompes.enable parameter is 1, the compression component of the KaiOS system is started, and when the value of the persist.sys.kaioscompes.enable parameter is 0, the compression component of the KaiOS system is closed, generally, the compression component in the mobile terminal of the existing KaiOS system is in a default closing state, and a professional is required to trigger the starting, so that the operation requirement is high.
S103, generating a system compression instruction according to the file identification and the started compression assembly.
For example, referring to fig. 2, the step S103 may specifically include:
s1031, determining the file data quantity corresponding to the file identifier;
s1032, determining the number of sub-packets according to the file data volume;
s1033, generating a system compression instruction carrying the sub-package number through the started compression assembly.
The number of the sub-packets may be multiple or single, and the file data amount of the file corresponding to the file storage address may be determined first, and since many servers have the maximum limit on the size of the single uploading file, the larger the file data amount, the larger the corresponding number of the sub-packets. The number of the sub-packets may be determined in various ways, for example, the maximum data amount of each sub-packet may be set in advance, then when determining the number of sub-packets of the log file to be compressed, the quotient between the file data amount and the maximum data amount may be calculated, and the quotient may be maximized, for example, when the quotient is 5.2, the quotient is 6 after the maximum integer, and when the quotient is 5, the quotient is 5 after the maximum integer.
Of course, the maximum data amount of each sub-packet may not be a constant value set in advance manually, and may be a variable, for example, the maximum data amount depends on the network transmission condition of the mobile terminal, and in general, the better the network transmission state, the larger the maximum data amount of each sub-packet may be.
For example, the step S1032 may specifically include:
acquiring the current network speed of the mobile terminal;
determining the total uploading duration according to the file data quantity and the network speed;
and determining the number of the sub-packets according to the total uploading duration.
The total uploading time length can be obtained by calculating the ratio between the file data quantity and the network speed. Several preset duration ranges and the number of sub-packets associated with each preset duration range can be set in advance, and then the current total uploading duration is determined in which duration range, and the corresponding number of sub-packets is acquired.
S104, compressing the log file to be compressed according to the system compression instruction.
Wherein compressing the log file substantially compresses the directory. When the number of the sub-packets is single, only the whole log file to be compressed is compressed, so that the log file is compressed into a single compressed packet by one key. When the number of sub-packets is plural, the log file to be compressed needs to be split into plural parts for compression, so that the log file to be compressed is compressed into plural compressed packets by one key, that is, when the number of sub-packets is plural, the step S104 specifically includes:
and sub-packing and compressing the log file to be compressed according to the compression instruction to obtain a plurality of local compression packets equal to the number of the sub-packets.
The purpose of sub-package compression is to split a large log file to be compressed into a plurality of small log files for compression, so as to obtain a local compression package, wherein the sub-package compression can be that a single process compresses the small log files in sequence, or a plurality of processes simultaneously compress the small log files, and the local compression package can be named according to the position sequence of the corresponding small log files in the whole log files, for example, according to the position sequence from front to back, log001, log002 and the like in sequence.
After compression, the mobile terminal may also transmit the compressed file to other terminals or servers through wireless communication modes such as WiFi network, cellular data network, bluetooth, etc.
For example, in fig. 2, after the log file to be compressed is subcontracting compressed according to the compression instruction, the data compression method may further include:
s1051, obtaining an uploading request, wherein the uploading request carries a network address of a server to be uploaded;
s1052, acquiring the current residual electric quantity of the mobile terminal according to the uploading request;
s1053, uploading the plurality of local compression packets to the server to be uploaded when the residual electric quantity is larger than the preset electric quantity; when the residual electric quantity is smaller than or equal to the preset electric quantity, determining a target local compression packet from the plurality of local compression packets according to the residual electric quantity; uploading the target local compressed packet to the server to be uploaded.
The user can log in the server webpage through the mobile terminal, and the uploading request is generated by performing corresponding operation on the webpage. For example, referring to fig. 3, the web interface of the server may provide a function of uploading and downloading files by the user, which may include an upload button (such as "+" in fig. 3), and the user pops up a file upload window by clicking the upload button, and selects one or more or all of the partial compression packages through the file upload window, and uploads the partial compression packages to the server through the network. It is easy to understand that when uploading all the partial compressed packets, it usually takes a certain time to transmit, so as to reduce the interruption of transmission, such as being influenced by the battery power or the network state, and the mobile terminal can select an optimized transmission mode according to its own operation condition. Specifically, whether the residual electric quantity is larger than the preset electric quantity can be analyzed first, if yes, the electric quantity is sufficient, the whole uploading task can be supported, if not, the electric quantity is insufficient, the phenomenon that the terminal is powered off after the uploading task is not completed can occur, and aiming at the situation, part of the local compression package can be selected for uploading.
For example, the step of determining the target partial compression packet from the plurality of partial compression packets according to the remaining power may specifically include:
acquiring the current power consumption speed, network speed and data volume of each local compressed packet of the mobile terminal;
determining the operable duration of the mobile terminal according to the residual electric quantity and the power consumption speed;
determining the uploading duration of each local compressed packet according to the data quantity and the network speed;
and determining a target local compressed packet from the plurality of local compressed packets according to the executable time length and the uploading time length.
The power consumption speed of the mobile terminal may be the sum of the power consumption speeds of all running applications currently. The operable duration may be a quotient of the remaining power and the power consumption speed, and the uploading duration may be a quotient of the data amount and the network speed. The method can sequentially select a plurality of local compression packets according to the naming sequence of the local compression packets, or randomly select a plurality of local compression packets to be combined, so that the number of the selected local compression packets is ensured to be as large as possible, and meanwhile, the sum of uploading time of the local compression packets is smaller than the operable time, thereby reducing the interruption phenomenon of compression operation as much as possible and avoiding the waste of transmission time when the local compression packets with transmission interruption are retransmitted. When the running condition of the subsequent mobile terminal is good, the uploading of the residual partial compression packet can be considered, for example, a prompt box is generated to prompt a user whether to continuously upload the residual compression packet.
As can be seen from the foregoing, the data compression method provided in the embodiment of the present application is applied to a mobile terminal, by obtaining a log compression request, where the log compression request carries a file identifier of a log file to be compressed, and then invoking a system attribute control component according to the log compression request to set a preset system parameter to a preset value, so that the mobile terminal starts a compression component according to the preset value, then generates a system compression instruction according to the file identifier and the started compression component, and compresses the log file to be compressed according to the system compression instruction, thereby fully utilizing a compression function of the system to implement file compression without installing additional compression tools, having small use limitation, and being capable of implementing one-key compression of a plurality of files, and having high compression efficiency.
According to the method described in the above embodiments, the present embodiment will be further described from the point of view of a data compression device, where the data compression device may be implemented as a separate entity, or may be integrated in a mobile terminal, and the mobile terminal may be a smart phone with a KaiOS system or other terminals.
Referring to fig. 4, fig. 4 specifically illustrates a data compression device provided in an embodiment of the present application, where the data compression device may include: the device comprises an acquisition module 10, a calling module 20, a generating module 30 and a compressing module 40, wherein:
(1) Acquisition Module 10

The compression triggering widget can be provided without having a compression function, and when a user starts the widget, a log compression request can be generated by clicking a designated key on a widget display interface, or a log compression request can be generated by selecting a compression key from a right-key menu after selecting a log file to be compressed. The generation of the log compression request may be triggered when a user clicks a designated key on the display interface. The log file to be compressed may be a single file, such as a text file with a single suffix extension log, or a folder, such as a folder including a plurality of log files. The file identity may be a file storage address for distinguishing between different files.
(2) Calling module 20
And the calling module 20 is used for calling the system attribute control component to set a preset system parameter to a preset value according to the log compression request, so that the mobile terminal starts the compression component according to the preset value.
The system attribute control component may be a component provided for a system initialization service, and the preset system parameter is a persistence.sys.kaioscompres.enable parameter in a system initialization file, and the preset value may be set manually, for example, 1. When the value of the susist.sys.kaioscompes.enable parameter is 1, the compression component of the KaiOS system is started, and when the value of the susist.sys.kaioscompes.enable parameter is 0, the compression component of the KaiOS system is closed, usually, the compression component of the existing mobile terminal is in a default closed state, and needs professional personnel to trigger the start-up, so that the operation requirement is higher.
(3) Generating module 30
A generating module 30, configured to generate a system compression instruction according to the file identifier and the started compression component.
For example, the generating module 30 is specifically configured to:
s1031, determining the file data quantity corresponding to the file identifier;
s1032, determining the number of sub-packets according to the file data volume;
s1033, generating a system compression instruction carrying the sub-package number through the started compression assembly.
The number of the sub-packets may be multiple or single, and the file data amount of the file corresponding to the file storage address may be determined first, and since many servers have the maximum limit on the size of the single uploading file, the larger the file data amount, the larger the corresponding number of the sub-packets. The number of the sub-packets may be determined in various ways, for example, the maximum data amount of each sub-packet may be set in advance, then when determining the number of sub-packets of the log file to be compressed, the quotient between the file data amount and the maximum data amount may be calculated, and the quotient may be maximized, for example, when the quotient is 5.2, the quotient is 6 after the maximum integer, and when the quotient is 5, the quotient is 5 after the maximum integer.
Of course, the maximum data amount of each sub-packet may not be a constant value set in advance manually, and may be a variable, for example, the maximum data amount depends on the network transmission condition of the mobile terminal, and in general, the better the network transmission state, the larger the maximum data amount of each sub-packet may be.
For example, in executing the above step S1032, the generating module 30 is further configured to:
acquiring the current network speed of the mobile terminal;
determining the total uploading duration according to the file data quantity and the network speed;
and determining the number of the sub-packets according to the total uploading duration.
The total uploading time length can be obtained by calculating the ratio between the file data quantity and the network speed. Several preset duration ranges and the number of sub-packets associated with each preset duration range can be set in advance, and then the current total uploading duration is determined in which duration range, and the corresponding number of sub-packets is acquired.
(4) Compression module 40
The compression module 40 is configured to compress the log file to be compressed according to the system compression instruction.
Wherein compressing the log file substantially compresses the directory. When the number of the sub-packets is single, only the whole log file to be compressed is compressed, so that the log file is compressed into a single compressed packet by one key. When the number of sub-packets is plural, the log file to be compressed needs to be split into plural parts for compression, so that the log file to be compressed is compressed into plural compressed packets by one key, that is, when the number of sub-packets is plural, the compression module 40 is specifically configured to:
and sub-packing and compressing the log file to be compressed according to the compression instruction to obtain a plurality of local compression packets equal to the number of the sub-packets.
The purpose of sub-package compression is to split a large log file to be compressed into a plurality of small log files for compression, so as to obtain a local compression package, wherein the sub-package compression can be that a single process compresses the small log files in sequence, or a plurality of processes simultaneously compress the small log files, and the local compression package can be named according to the position sequence of the corresponding small log files in the whole log files, for example, according to the position sequence from front to back, log001, log002 and the like in sequence.
After compression, the mobile terminal may also transmit the compressed file to other terminals or servers through wireless communication modes such as WiFi network, cellular data network, bluetooth, etc.
For example, referring to fig. 5, the data compression apparatus further includes an upload module 50 for:
after the compression module 40 performs sub-packing compression on the log file to be compressed according to the compression instruction, an uploading request is obtained, where the uploading request carries a network address of a server to be uploaded;
acquiring the current residual electric quantity of the mobile terminal according to the uploading request;
when the residual electric quantity is larger than the preset electric quantity, uploading the plurality of local compression packets to the server to be uploaded;
when the residual electric quantity is smaller than or equal to the preset electric quantity, determining a target local compression packet from the plurality of local compression packets according to the residual electric quantity; uploading the target local compressed packet to the server to be uploaded.
The user can log in the server webpage, and the uploading request is generated by performing corresponding operation on the webpage. For example, referring to fig. 3, an upload button may be included on the web interface of the server, and the user pops up a file upload window by clicking the upload button, and selects one or more or all of the local compression packages to upload to the server through the file upload window. It is easy to understand that when uploading all the partial compressed packets, it usually takes a certain time to transmit, so as to reduce the interruption of transmission, such as being influenced by the battery power or the network state, and the mobile terminal can select an optimized transmission mode according to its own operation condition. Specifically, whether the residual electric quantity is larger than the preset electric quantity can be analyzed first, if yes, the electric quantity is sufficient, the whole uploading task can be supported, if not, the electric quantity is insufficient, the phenomenon that the terminal is powered off after the uploading task is not completed can occur, and aiming at the situation, part of the local compression package can be selected for uploading.
For example, the uploading module 50 is specifically configured to:
acquiring the current power consumption speed, network speed and data volume of each local compressed packet of the mobile terminal;
determining the operable duration of the mobile terminal according to the residual electric quantity and the power consumption speed;
determining the uploading duration of each local compressed packet according to the data quantity and the network speed;
and determining a target local compressed packet from the plurality of local compressed packets according to the executable time length and the uploading time length.
The power consumption speed of the mobile terminal may be the sum of the power consumption speeds of all running applications currently. The operable duration may be a quotient of the remaining power and the power consumption speed, and the uploading duration may be a quotient of the data amount and the network speed. The method can sequentially select a plurality of local compression packets according to the naming sequence of the local compression packets, or randomly select a plurality of local compression packets to be combined, so that the number of the selected local compression packets is ensured to be as large as possible, and meanwhile, the sum of uploading time of the local compression packets is smaller than the operable time, thereby reducing the interruption phenomenon of compression operation as much as possible and avoiding the waste of transmission time when the local compression packets with transmission interruption are retransmitted. When the running condition of the subsequent mobile terminal is good, the uploading of the residual partial compression packet can be considered, for example, a prompt box is generated to prompt a user whether to continuously upload the residual compression packet.
In the implementation, each unit may be implemented as an independent entity, or may be implemented as the same entity or several entities in any combination, and the implementation of each unit may be referred to the foregoing method embodiment, which is not described herein again.
As can be seen from the foregoing, the data compression device provided in this embodiment is applied to a mobile terminal, the obtaining module 10 obtains a log compression request, where the log compression request carries a file identifier of a log file to be compressed, and then the calling module 20 calls a system attribute control component according to the log compression request to set a preset system parameter to a preset value, so that the mobile terminal starts a compression component according to the preset value, and then the generating module 30 generates a system compression instruction according to the file identifier and the started compression component, and the compressing module 40 compresses the log file to be compressed according to the system compression instruction, thereby fully utilizing a compression function of the system to realize file compression, without installing additional compression tools, having small use limitations, and being capable of realizing one-key compression of multiple files, and having high compression efficiency.
