Description
Technical Field
The invention relates to the field of internet, in particular to a domain name-based classified information issuing method and system.
Background
Classified information and display thereof are a new generation of internet application mode, and the network is more popularized and closer to life, thereby facilitating life. The classification information can be similar to advertisement, for traditional newspapers and periodicals, almost every newspaper and periodicals has less figure of classification information, and the newspapers and periodicals with better handling capacity have larger classification information. However, no matter how well the classified information advertisements on the newspapers and periodicals are made, the search is always inconvenient. Moreover, as the number of classified information increases, the searching difficulty also increases, and the classified information is difficult to store, for example, the newspaper is discarded after being viewed and cannot be found any more.
Due to the rise of the classification information website, the defects of the traditional classification advertisement are well made up. The classified information has large information quantity, and the information is online at any time and never lost. More importantly, by utilizing classified search, the user can be ensured to conveniently and rapidly inquire at any time and any place.
The classified information publishing method of the current classified information website generally comprises the following steps: the operator of the classification information website publishes the relevant classification information to the classification information website, and then the user inquires the relevant classification information by visiting the classification information website. Moreover, the basic flow of user access to the existing categorized information website includes the following steps (see fig. 1): the browser is opened (S110), a domain name for accessing the classification information site is input into the browser (S120), the classification information site is opened, and the classification information is searched or viewed (S130).
Further, for example, the existing method for publishing the classification information by the website adopts a URI (Uniform Resource Identifier) manner. The format is defined as: protocol// domain name/directory/file # fragment identifier.http://www.a.cn/qiche/detail.php？id＝xxxxx&minprice＝10_15&PGTID＝ 0d100000-0000-1751-1a36-c153441fbff9&ClickID＝7As an example. Http is the internet protocol name, qiche is the directory (classification), and then detail.php is the file name, which represents the specific classification information, "? "the latter parameters provide specific classification information data to detail.
In view of the URI example, the conventional classification information distribution method has three problems: 1) in the URI protocol, the directory and the file are generally in an ASCII format, and the abstract information of specific analysis information cannot be visually displayed, so that the user can only click the URI to enter a webpage to see the abstract information. 2) Due to the needs of the website technology system, some necessary system parameters are added to the URI. When the user shares, the URI link character is long and not friendly on the mobile terminal. 3) The URI used by the existing classified information issuing method is not easy to remember and is easy to be confused, so that the potential safety hazard of the Internet in use is generated.

Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the accompanying drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the corresponding technical effects can be fully understood and implemented. The embodiments and the features of the embodiments can be combined without conflict, and the technical solutions formed are all within the scope of the present invention.
Additionally, the steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
For better understanding of the technical solutions of the present invention, technical terms related to the embodiments of the present invention are described before specific descriptions of the embodiments of the present invention are performed.
1. The Domain Name System (DNS) is a service of the internet. It acts as a distributed database that maps domain names and IP addresses to each other, enabling people to more conveniently access the internet. The DNS uses TCP and UDP ports 53. Currently, the limit for the length of the domain name at each level is 63 characters, and the total length of the domain name cannot exceed 253 characters.
2. The Top level Domain (or Top level Domain name; english: Top-level Domain; english abbreviation: TLD) is the highest level Domain except the root among the internet DNS levels, and is stored in the namespace of the DNS root Domain. The top domain name is the last part of the domain name, i.e. the letters after the last point of the domain name, e.g. in example.
When a user accesses a website, the user usually accesses the website by using a host name or a domain name, rather than directly accessing the website by using an IP address. The reason why we do not use IP addresses for access is that IP addresses are a set of pure numbers that are difficult to remember relative to host or domain names.
For example, a company's website has an IP address of 45.120.243.8 and a domain name of www.teleinfo.cn. If we use the IP address to access the website, it is difficult for the user, and it is easier to remember by using the domain name. However, unlike humans, computers are relatively difficult to understand a name (e.g., domain name) because they are good at handling a long string of numbers. To solve this problem, there is a DNS service. The DNS protocol, one of its functions, is to look up IP addresses by domain name.
The invention is different from the prior classified information issuing method, and provides a novel classified information issuing method based on the domain name for the first time. The domain name of the classification information is as follows: the ICP proved Yue B2-20090191 Internet records and information. In addition, for the convenience of searching, the domain name at the upper level of the domain name of the classification information (called "classification domain name", such as "Internet record information") can point to the searching page of the classification. Each piece of information corresponds to a domain name, so the information has uniqueness to a certain degree, can be used for network identification, authority information publishing and the like, and has the characteristics of convenience, rapidness and accuracy by publishing the classified information in a domain name mode.
(embodiment one)
Fig. 2 is a schematic flow chart of a domain name-based classification information issuing method according to a first embodiment of the present invention, and the following describes an embodiment of the present invention with reference to fig. 2.
As shown in fig. 2, the flow of the method for issuing classification information based on domain name according to this embodiment includes the following steps.
In step S210, the content of the classification information to be distributed is distributed to the classification information site host.
The "categorized information site host" refers to a physical server having a WEB service system and a DNS domain name registration management function. The adopted content distribution method is completed by supporting information system software, such as: content Management System (CMS).
Specifically, the publisher organizes and sorts the content of the classification information, identifies the classification to which the content of the classification information belongs, and then publishes the classification information content with the classification identification to the WEB service system of the classification information site host.
In the present embodiment, classification of classified information contents is performed according to sub-domains of domain names, for example, for contents related to "ICP wityue B2-20090191" internet docket information, classification flags thereof may be set as: information "and may use the identification as a categorical domain name for the content. Wherein, the information is a top-level domain, and the Internet records are a second-level sub-domain.
In step S220, a domain name resolution record of the site hosting WEB service (also referred to as "category information domain name" in the present specification) corresponding to the category information content is added to the DNS zone file, wherein the domain name resolution record of the WEB service is a secondary sub-domain or a multi-level sub-domain under the top level domain.
Specifically, after the host of the classified information site receives the published classified information content, the WEB service system converts the classified information content WEB page into an independent WEB virtual site. Through the domain name registration management function of the DNS, setting the domain name of the WEB virtual site according to the classification identification of the classification information content, and then issuing the domain name A record (such as teleinfo. cn. icp. tld A12.21.32.2) mapped by the IP address of the WEB virtual site to a DNS service ZONE file (see DNS protocol message (RFC 1035)).
Through the steps, the content publishing of the classification information based on the domain name is realized, and when a user needs to obtain the content of the classification information, the content of the classification information can be directly obtained from the host of the classification information site only by accessing the domain name of the classification information. For example: the user inputs the domain name information 'ICP Zhenyao B2-20090191, Internet records, information' corresponding to the classified information content to be searched in the address bar of the browser, and the classified information site host directly returns the classified information content corresponding to the classified information domain name to the user. Because each piece of classified information corresponds to one classified information domain name, the information has uniqueness to a certain extent and can be used for network identification, authority information issuing and the like.
(second embodiment)
Fig. 3 is a flowchart illustrating a method for issuing classification information based on a domain name according to a second embodiment of the present invention. The method flow of the present embodiment is explained below with reference to fig. 3.
In order to facilitate the user to obtain information, the classified information content can be directly obtained from the classified site search engine, so that step S230 and step S240 are added to this example on the basis of the first embodiment.
This embodiment is a preferred embodiment of the present invention, and step S230 and step S240 need to be executed in addition to step S210 and step S220 of embodiment one. Since step S210 and step S220 have been specifically described in the first embodiment, the contents of these two steps are not repeated here, and only step S230 and step S240 are described.
In step S230, the classification information content of the site and the classification domain name address corresponding thereto are issued to the classification site search engine. The classification domain name is the upper level domain name of the classification information domain name, for example, the information is the upper level domain name of the information of ICP Zhengyue B2-20090191.
A "classified site search engine" has the capability of total-site searches as well as some classified search. When a user searches for a certain classification information, the user can directly reach the classification search engine service by accessing the classification domain name, and only the classification information content under the classification is searched.
In step S240, the classified site search engine is classified, and it is confirmed that the domain name of the classified site search engine has been DNS-resolved.
Since the classified information contents are already published to the classified site search engine with the classified domain name address in step S230, and the classified information contents are already summarized into a specific classification, the classified site search engine also needs to be classified in advance in order to be able to acquire the classified information contents in the classified site search engine. It should be noted that, when classifying the search engines of classified sites, it is required to ensure that the classifications of the search engines of classified sites correspond to the classifications of classified information contents one to one.
In this step, the categorized information site host categorizes the categorized site search engine. Specifically, by using a domain name registration management function of a DNS of a host of a classified information site, domain names of different search engines are determined by classifying search engines of the classified site according to a subdomain of the domain name. When the classification is carried out, the classification mark of the search engine of the classification site corresponds to the classification mark of the classification information content, and the classification mark have relevance.
It should be noted that, in this embodiment, the domain name of the default classified site search engine is already resolved by the DNS server, and if the domain name is not resolved, resolution is further enabled. The purpose of this default setting is to ensure that the search engines of the classified sites that have been classified according to sub-domain are pre-existing, and by entering the classified domain name in the browser, the corresponding engine can be obtained accurately, and the user can obtain the classified information content more quickly.
Here, whether the domain name of the categorized website search engine is resolved by the DNS server is verified by the domain name registration management function of the categorized information website host, and specifically, the following two methods may be adopted: (1) since the analyzed domain name is recorded in the database at the background, whether the domain name is analyzed or not can be verified by inquiring the background database; (2) for resolved domain names, the DNS resolution server is accessible via the DNS "dig" tool, so that it can also be verified whether the domain name has been resolved.
The function of the "domain name of the search engine of classified site" is to make the "search engine of classified site" accessible through the domain name. When a user searches for a certain classification information, the user can directly reach the classification search engine service by accessing the classification domain name, and only the classification information content under the classification is searched. If the http:// shoe and hat information is accessed, entering a shoe and hat classification information search engine homepage, and only retrieving the shoe and hat information under the search engine homepage; when http:// car. information is accessed, a car classification information search engine homepage is entered under which only car information can be retrieved.
The search engine pages pointed to by the domain names of the search engines of different classification sites are different, and the more domain name levels, the more specific the information that can be searched by the search engine pages. For example, in classification information corresponding to the domain name of "XX brand", "shoes", "hat", "information" the information of "XX brand" can be searched under a search engine of a classification site of the domain name of "shoes", "hat", "information" can be searched; under a classified site search engine of a domain name of 'shoes, hats and information', information of 'shoes' and 'XX brand' can be searched; under a classified site search engine of a domain name of 'XX brand, shoes, hats and information', only XX brand information can be searched.
According to the embodiment of the invention, the classification information content of the site and the classification domain name address corresponding to the classification information content are issued to the classification site search engine, the classification of the classification site search engine is carried out, and the domain name of the classification site search engine is confirmed to be resolved by the DNS, so that when a user accesses the classification information content, the classification information content can be obtained from the classification site host according to the classification information domain name, and the classification information content can be obtained from the classification site search engine according to the classification domain name, so that the information acquisition of the user is facilitated.
In addition, the embodiment can acquire the classified information content from the search engine according to the classified domain name, so that the classified information to be searched can be conveniently, quickly and accurately positioned. And the current DNS service and browser support the IDN domain name, so that security holes such as phishing of the ASCII domain name can be avoided.
(third embodiment)
After the classified information content is distributed by the method of the second embodiment, the user can search and access the classified information content by the following steps (refer to fig. 4).
In step S310, the browser is opened, and domain name information corresponding to the content of the classification information to be searched is input in the browser address field.
In step S320, it is determined that domain name information to be searched is input in the browser, and if "category information domain name" is input, the process proceeds to step S330, and if "category domain name" is input in the browser, the process proceeds to step S340.
It should be noted that all classified domain names are reserved by the DNS resolution service.
In step S330, the system directly returns the content of the digest information corresponding to the "digest information domain name" to be currently searched.
In step S340, the system enters a classified information search engine page, where the user can perform further search of classified content, and after retrieving corresponding content, click on detailed information, and the system returns the content of the classified information to be currently searched.
The method for issuing the classification information based on the domain name has the advantages that: the domain name classification information can be accurately positioned, the domain name with the classification information can be distributed, a user can conveniently judge the approximate content of the information from the domain name address, and finally whether the domain name is opened or not is determined. The domain name is used as a platform for issuing the classification information, so that the occurrence of a 'phishing' website security case can be effectively avoided.
In order to better understand the present invention, a case of information distribution by using the method of distributing classification information based on domain name according to the present embodiment will be described below. The following are two typical use cases of the domain name based classification information publishing method and the access method, which include but are not limited to these two use cases.
Example one: internet filing information issuing method based on domain name
Case release flow:
1) and classifying different information based on the top level domain to divide a second level sub-domain of the domain name.
For example, the Internet records and information. The top level domain is information and the second level domain is internet filing. Thus, the Internet records become an information classification.
2) Below the second level domain classification domain name, a third level domain name is given. The tertiary domain name is directly positioned to specific information, namely the tertiary domain is analyzed to a specific classification information content site. For example, "ICP witness B2-20090191. internet docket information" domain name, which indicates that the domain name points to specific information of internet docket classification.
3) Under the "classified domain name", a search engine ("http:// internet docket. info") for classified information is built under which the user can retrieve information related to "internet docket".
Internet users access top-level domain based classification information:
1) and opening the browser.
2) Inputting a domain name corresponding to the access classification information in an address bar of the browser, such as: "http:// ICP Zhengyue B2-20090191. Internet records information".
3) Directly returns the specific information of 'ICP Zhengyue B2-20090191' Internet record.
The user enters a classification domain name in the address bar of the browser, such as: the method comprises the steps of returning to an internet filing classified search engine page if the user further acquires 'ICP Zhengyue B2-20090191' internet filing specific information, performing information classified retrieval on the search engine page, namely inputting 'ICP Zhengyue B2-20090191' for searching, and then returning to 'ICP Zhengyue B2-20090191' internet filing specific information by the system.
Example two: internet domain name information publishing method based on domain name
Case flow:
1) and classifying different information based on the top level domain to divide a second level sub-domain of the domain name.
Such as "cn information". The top level field is ". info", the second level field is "cn". Thus "cn" becomes a classification of information.
2) Below the second level domain classification domain name, a third level domain name is given. The tertiary domain name is directly located to specific information. Cn. info "domain name, for example, indicates that the domain name points to specific information classified with the particulars.
3) Under the "classified domain name", a search engine of classified information is established ("http:// cn. information"), and the user retrieves the related domain name information of "cn top level domain" under the classified domain name.
The internet user accesses the classification information based on the internet domain name information of the top level domain:
1) opening a browser;
2) inputting a domain name corresponding to the access classification information in an address bar of the browser, such as: "http:// teleinfo. cn info".
3) And directly returning relevant information corresponding to the domain name of' teleinfo.
The user enters a classification domain name in the address bar of the browser, such as: if the user wants to further acquire information corresponding to the 'teleinfo', classified information retrieval is carried out on the search engine page, namely the 'teleinfo' is input for searching, and then the system returns specific information corresponding to the 'teleinfo'.
According to the domain name-based classified information issuing method, each piece of information corresponds to one domain name, so that the information is unique to a certain degree and can be used for network identification.
(example four)
Fig. 5 is a schematic structural diagram of a domain name-based classification information distribution system according to an embodiment of the present invention. The system composition and the respective structural functions of the present embodiment are explained below with reference to fig. 5.
The classification information distribution system 400 includes: publishing platform 410, classification information site host (may be simply referred to as site host) 420, DNS resolution server (may be simply referred to as DNS server) 430, and classification site search engine (may be simply referred to as search engine) 440.
The publishing platform 410 publishes the taxonomy information content to the taxonomy information site host 420.
The publishing method used by the publishing platform 410 may be implemented by supporting information system software, such as: content Management System (CMS). Specifically, the distribution platform 410 organizes and sorts the classified information content, identifies the classification to which the classified information content belongs, and distributes the classified information content with the classification identification to the classified information site host 420 (specifically, the WEB service system 421 described later).
In the present embodiment, classification of classified information contents is performed according to sub-domains of domain names, for example, for contents related to "ICP wityue B2-20090191" internet docket information, classification flags thereof may be set as: information "and may use the identification as a categorical domain name for the content. Wherein, the information is a top-level domain, and the Internet records are a second-level sub-domain.
As shown in FIG. 5, a taxonomy site host 420 is connected to the publishing platform 410, DNS server 430, and taxonomy site search engine 440, the taxonomy site host 420 being a physical server that includes a WEB services system 421 and DNS domain name registration management module 422.
The classification information site host 420 adds a site host WEB service domain name resolution record of the classification information content to a DNS zone file of the DNS server 430, wherein the domain name resolution record is a secondary sub-domain or a multi-level sub-domain under the top level domain; and simultaneously, the classified information content of the site and the classified domain name address corresponding to the classified information content are issued to the classified site search engine 440.
Specifically, after the categorized information site host 420 receives the published categorized information content, the WEB service system 421 will convert the categorized information content WEB page into an independent WEB virtual site. The DNS domain name registration management module 422 sets the domain name of the WEB virtual site according to the classification identifier of the classification information content, for example, since the identifier is "internet record information", the domain name of the classification information content corresponding to the "ICP, yue, B2-20090191" internet record information may be set to "ICP, yue, B2-20090191. Then, the DNS domain name registration management module 422 publishes the domain name a record (e.g., teleinfo. cn. icp. tld A12.21.32.2) mapped to the IP address of the WEB virtual site to the DNS zone file of the DNS server 430 (see DNS protocol message (RFC 1035)).
In addition, to facilitate the user to obtain information, the classification information site host 420 also issues the classification information content and its corresponding classification domain name address to the classification site search engine 440. The classification domain name is the upper level domain name of the classification information domain name, for example, the information is the upper level domain name of the information of ICP Zhengyue B2-20090191. When the user cannot accurately know the domain name of the classified information content to be searched, the classified domain name can be input in the browser, and then the corresponding classified information content is searched through the classified site search engine 440, and then the classified site search engine 440 can directly return the corresponding classified information content stored locally to the user, so that the user information can be conveniently acquired.
Also, the categorized info site host 420 further categorizes the categorized site search engine 440. Specifically, the DNS domain name registration management module 422 of the taxonomy information site host 420 also categorizes the taxonomy site search engines 440 by subdomain of the domain name to determine the domain name of the different search engines 440. The classification is performed such that the classification identifier of the classification site search engine 440 corresponds to the classification identifier of the classified information content, and the classification identifiers have an association.
It should be noted that the domain name of the search engine 440 of the default classified site of the system of this embodiment has already been resolved by the DNS server 430, and if there is no resolution, further resolution is opened. The purpose of this default setting is to ensure that the classified site search engine 440, which has been classified by subdomain, is pre-existing, and that the corresponding engine can be accurately obtained by entering the classified domain name in the browser, so that the user can more quickly obtain the classified information content.
Here, the domain name registration management module 422 of the categorized information site host 420 is used to verify whether the domain name of the categorized site search engine 440 is resolved by the DNS server 430, and specifically, the following two methods may be adopted: (1) since the analyzed domain name is recorded in the database at the background, whether the domain name is analyzed or not can be verified by inquiring the background database; (2) for resolved domain names, the DNS resolution server is accessible via the DNS "dig" tool, so that it can also be verified whether the domain name has been resolved.
The category site search engine 440 has the capability of total-site searches as well as some category search. When a user searches for a certain classification information, the user can directly reach the classification search engine service by accessing the classification domain name, and only the classification information content under the classification is searched. Further, as described above, the classification site search engine 440 has also been classified according to the subdomains of the domain name, and classified from top to bottom to include in a hierarchical state.
And a DNS server 430 that stores a DNS zone file and performs domain name and IP address conversion corresponding thereto. The operation principle of the DNS server 430 is substantially the same as that of the DNS server in the related art, and will not be described herein. When a user inputs a domain name in a browser, the DNS server 430 returns different contents to the user according to the type of the input domain name, and if the domain name is a "classification information domain name", directly returns the content of classification information corresponding to the "classification information domain name" to be searched currently, and if the domain name is a "classification domain name", the user enters a page of the classification site search engine 440, and the user can perform further retrieval of the classification content on the page.
According to the domain name-based classified information issuing system, each piece of information corresponds to one domain name, so that the information is unique to a certain degree and can be used for network identification.
Although the embodiments of the present invention have been described above, the above descriptions are only for the convenience of understanding the present invention, and are not intended to limit the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
