Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
It can be known from the description of the background art that in the existing domain name matching classification, matching classification is realized by calculating HASH values, but the number of domain names is huge at present, and a large amount of memory is occupied, so that the running speed is influenced, and further the matching efficiency is influenced.
Therefore, to solve the above problem, an embodiment of the present application provides a domain name classification matching method, and with reference to fig. 1, the method includes:
and S11, acquiring the predefined domain name classification file according to the predefined generation rule.
In this step, firstly, according to predefined generation rules, the domain names corresponding to various resource websites are classified to obtain predefined domain name classification files corresponding to the resource websites which are allowed to access the relevant classes of work, that is, all the domain names which are allowed to access are stored in the predefined domain name classification files for subsequent matching and searching.
And S12, when receiving the domain name request, acquiring the domain name classification file to be matched according to the predefined generation rule.
In this step, after receiving the domain name requested to be accessed by the user, the domain name requested to be accessed is classified according to the predefined generation rule in step S11, so as to obtain a domain name classification file to be matched.
And S13, matching the domain name classification file to be matched with a predefined domain name classification file, and judging whether the domain name classification file to be matched is matched with the predefined classification file.
In this step, the domain name classification file to be matched obtained in step S12 is matched and searched with the predefined domain name classification file in step S11, and it is determined whether the domain name classification file to be matched can be found in the predefined classification file, that is, whether the classification corresponding to the domain name requested to be accessed by the user is in the domain name classification file allowed to be accessed.
And S14, if the matching is successful, acquiring the classification file corresponding to the requested domain name, and allowing the resource website corresponding to the requested domain name to be accessed.
And S15, if the matching fails, intercepting the domain name of the request to access the corresponding resource website.
After the matching in step S13, two results are generated, that is, the matching is successful and the matching is unsuccessful, if the matching is successful, that is, the domain name classification file to be matched can be found in the predefined classification file, it indicates that the resource website corresponding to the requested domain name is allowed to access, and if the matching is unsuccessful, the resource website corresponding to the requested domain name is intercepted, and the access cannot be allowed.
The domain name classification matching method disclosed in the embodiment of the application realizes rapid resource positioning matching directly through the rule conversion of the domain name, avoids the influence of complex operation rules on matching efficiency, meanwhile, when the domain name is subjected to domain name matching classification, the searching matching is only searched in a file, and the searching is not performed in a memory, so that the occupation of the memory is reduced, and the classification and the domain name in the file are stored in a one-to-one manner, so that the conflicting domain name does not exist, and further the matching efficiency is not influenced.
From the above, the embodiment of the present application discloses a domain name classification matching method, which includes obtaining a predefined domain name classification file according to a predefined generation rule; then when a domain name request is received, acquiring a domain name classification file to be matched according to the predefined generation rule; then matching the domain name classification file to be matched with a predefined domain name classification file; if the matching is successful, the classification file corresponding to the requested domain name is obtained, the resource website corresponding to the requested domain name is allowed to be accessed, and if the matching is failed, the access is intercepted. The method for searching only uses file searching, does not search in the memory, namely the memory occupation is converted into the hard disk storage occupation, so that the memory occupation is greatly reduced.
Optionally, the predefined generation rule may be obtained by specifically adopting the following method:
dividing the domain name by taking points in the domain name as a dividing unit;
creating a directory step by step for the divided domain names;
and creating a classification file in a directory part at the tail end, wherein the classification file comprises specific information of domain name classification.
In S11, the finally created classification file is a predefined domain name classification file, and the classification file includes each classification information corresponding to the domain name permitted to be accessed; in S12, the finally created classified file is a domain name classified file to be matched, and the classified file includes category information corresponding to the domain name to be matched.
For example: the domain name is www.baidu.com, and the division unit is' in the domain name, and the domain name is divided into: www, baidu and com, then creating directories step by step for the divided domain names, wherein the created directories are www- > baidu- > com, and finally creating a classification file index.
For another example: the domain name is www.news.baidu.com, and the domain name is divided into the following parts by taking the point as a division unit: www, news, baidu and com, creating a directory www- > news- > baidu- > com after division, and finally creating a classification file index.
Optionally, before obtaining the domain name classification file to be matched, the method further includes:
and generating a resource path for the requested domain name, and generating the classification of the domain name to be matched according to the resource path.
In this step, the resource path can further represent the location and type of the requested domain name, for example, the resource path corresponding to the domain name www.baidu.com is www/baidu/com/index.
Optionally, matching the domain name classification file to be matched with a predefined domain name classification file includes:
and searching the domain name classification file to be matched corresponding to the resource path according to the resource path generated by the domain name request.
