Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The embodiment of the invention provides a method for extracting a feature code of a WeChat article, which is to directly extract a WeChat article feature code and a code value corresponding to the feature code from a permanent link as shown in figure 1, and the embodiment of the invention provides the following specific steps:
101. and acquiring the browsing link of the WeChat seal.
In the embodiment of the invention, a developer or a merchant applies for a public number on a WeChat public platform, and a WeChat article can be published through the WeChat public number, wherein the WeChat article specifically comprises characters, pictures, voice, video and the like. In addition, the instruction of opening the WeChat seal by using the browser can be triggered, and the WeChat article is opened by using the browser, so that the browsing link corresponding to the WeChat seal is obtained at the same time.
For the embodiment of the invention, one optimization operation is to pre-write a control encapsulated with a simulated click operation, so that the control is started to automatically open the WeChat article by using a browser and acquire a browsing link, or to execute a browsing link operation for crawling the WeChat article by using crawler software.
The browsing links of the acquired wechat articles include links beginning with "http://" and "https://". The method avoids the missing collection of browsing links due to different http protocols.
102. And judging whether the browsing link of the WeChat article is a permanent link or not.
The browsing link of the WeChat article can be a temporary link or a permanent link. For the temporary link, the WeChat background can preset browsing timeliness and browsing upper limit times, so that the temporary link is invalid and a user cannot access the temporary link any more when a certain time is exceeded or the browsing amount of the WeChat article reaches a certain limit.
The permanent link is a link with a static and absolute address, the WeChat background cannot preset access time limit or browsing amount upper limit on the permanent link of the WeChat article, and the WeChat article is allowed to be accessed all the time by using the permanent link unless the WeChat background deletes the WeChat article.
For the embodiment of the present invention, the feature code information included in the temporary link of the WeChat article is incomplete, such as: typically only contains the first signature (i.e., Biz) for identifying the WeChat public Account, but not Mid, Idx, Sn. However, the feature code information contained in the permanent link is complete, so that after the browsing link of the WeChat article is acquired, whether the link is a permanent link needs to be judged in advance, so that the operation of extracting the feature code information is performed subsequently.
103. And if the browsing link of the WeChat article is judged to be a permanent link, extracting the feature codes of the WeChat article from the permanent link.
In the embodiment of the invention, the WeChat signature code at least comprises: a characteristic code (namely: Biz) for identifying the public account of the WeChat, a characteristic code (namely: Mid) for identifying the number of the pushed message, a characteristic code (namely: Idx) for identifying the position of the WeChat article in the message, and a characteristic code (namely: Sn) for identifying a random encryption string corresponding to the WeChat chapter.
For example: WeChat seals are permanently linked as follows:
https://mp.weixin.qq.com/s？__biz＝MjM5MzAxNjkwMA＝＝&mid＝2650476042&idx＝2&sn＝c1cf094f228249bdafbade6c1b0b1a92&chksm＝be92d32189e55a3716a44ab6e70fa06671b9ce6a6e451202d21f06d439d04b1b4790f9cec5c4&mpsha re＝1&scene＝1&srcid＝&sharer_sharetime＝1568949234670&sharer_shareid＝4d909ce64954591c250aa10079487374&key＝f0b3b85af89c30e9005cc4c7e62db3a187796970348c3f03b560499254bd584a3d5e4245d9faba0855dc57def84983e8708cf74cfbe7ad7b1cd4fac44ceda96561160bd08380c43545a0a5017e1da1f9&asc ene＝1&uin＝MjkwNDQ1Njc0MA％3D％3D&devicetype＝Windows+7&version＝62060841&lang＝zh_CN&pass_ticket＝IKPy9HeslOQgWOflq4rbHiWSCtajyie ZDJgjrZPjVDQlvYkpE07dEiCSZeu％2BGZ5％2F
the embodiment of the invention provides a method for extracting a feature code of a WeChat article. Compared with the prior art, the method and the device for acquiring the characteristic code information solve the problems that the characteristic code information obtained from the source code analysis is incomplete and the efficiency is caused by the fact that the characteristic code information needs to be acquired through supplement operation.
In order to explain the above embodiments in more detail, another method for extracting feature codes of a wechat article is further provided in the embodiments of the present invention, as shown in fig. 2, the method is to pre-construct an extraction sequence rule corresponding to a plurality of feature codes and an element composition rule corresponding to each feature code, so as to generate a regular expression for extracting feature code information, so as to implement an operation of automatically extracting feature code information from a permanent link, and for this, the embodiments of the present invention provide the following specific steps:
201. and constructing an extraction sequence rule corresponding to the feature code.
Wherein, the WeChat seal feature code is at least: a characteristic code (namely: Biz) for identifying the public account of the WeChat, a characteristic code (namely: Mid) for identifying the number of the pushed message, a characteristic code (namely: Idx) for identifying the position of the WeChat article in the message, and a characteristic code (namely: Sn) for identifying a random encryption string corresponding to the WeChat chapter.
In the embodiment of the present invention, the detailed statement about the step may specifically include the following:
firstly, obtaining a historical browsing link of the WeChat article, wherein the historical browsing link is a permanent link, and analyzing the historical browsing link to obtain character string information contained in the historical browsing link.
For the embodiment of the invention, the association existing among a plurality of feature codes is searched by analyzing the historical browsing links. In order to optimize the processing of the historical browsing link, after the historical browsing link is acquired, redundant character string information in the historical browsing link can be preferentially deleted, for example: for the permanent link illustrated in step 103, deleting the redundant string information results in the following browsing link:
https://mp.weixin.qq.com/s？__biz＝MjM5MzAxNjkwMA＝＝&mid＝2650476042&idx＝2&sn＝c1cf094f228249bdafbade6c1b0b1a92
secondly, searching character strings respectively containing preset elements in the character string information contained in the historical browsing link to obtain a plurality of feature codes, and determining the arrangement sequence of the feature codes in the character string information.
The preset elements comprise index character elements, letter elements and character elements. In the embodiment of the invention, the feature codes corresponding to different preset elements are searched in the character string information contained in the history browsing link according to the difference of the preset elements contained in different feature codes.
For example: biz is composed of upper and lower case letters, numbers, and equal numbers, Mid is composed of all numbers, Idx is a digit, Sn is composed of a number and a lower case letter.
With the embodiment of the present invention, since the search operation is performed in the order from the first character string to the last character string included in the character string information, after the search operation is performed, the arrangement order of the feature codes in the history browsing link is obtained according to the order in which the feature codes are searched.
For example: the simplified browsing links are as follows:
https://mp.weixin.qq.com/s？__biz＝{Biz}&mid＝{Mid}&idx＝{Idx}&sn＝
{Sn}
thereby obtaining a ranking order of the plurality of feature codes: "Biz, Mid, Idx, Sn".
And finally, constructing an extraction sequence rule corresponding to the feature codes according to the arrangement sequence. The rule of the extraction order is that in the character string information contained in any one WeChat chapter browsing link, the position ordering among a plurality of feature codes is 'Biz, Mid, Idx and Sn', correspondingly, if the operation of extracting the feature codes is executed on any one permanent link, the extraction order of the feature codes is 'Biz, Mid, Idx and Sn'
202. And generating element composition rules corresponding to each feature code.
It should be noted that, in this step, the component included in the feature code is also obtained by analyzing the history browsing link. In the embodiment of the present invention, the detailed statement about the step may specifically include the following:
firstly, respectively determining preset elements contained in each feature code, and generating element composition rules respectively corresponding to each feature code according to the preset elements.
For example: biz is composed of three preset elements including upper and lower case letters, numbers and equal numbers, Mid is composed of all number preset elements, Idx is one-digit number preset element, and Sn is composed of number and lower case letter preset element.
And secondly, generating element composition rules corresponding to each feature code according to preset elements.
It should be noted that, in the embodiment of the present invention, for the permanent link of the WeChat document acquired in real time, the extraction sequence rule and the element composition rule are combined, so that the positions of different feature codes in the permanent link can be analyzed and determined, and the feature code information can be further intercepted on the basis of the position.
203. And acquiring the browsing link of the WeChat seal.
In the embodiment of the present invention, for the statement of this step, refer to step 101, and will not be described herein again.
It should be noted that, in order to optimize the processing of the browsing link, after the browsing link is acquired, the redundant character string information in the browsing link may be preferentially deleted, for example: for the permanent link illustrated in step 103, deleting the redundant string information results in the following browsing link:
https://mp.weixin.qq.com/s？__biz＝MjM5MzAxNjkwMA＝＝&mid＝2650476042&
idx＝2&sn＝c1cf094f228249bdafbade6c1b0b1a92&
204. and judging whether the browsing link of the WeChat article is a permanent link or not.
In the embodiment of the present invention, specifically, the method for determining whether the link is a permanent link may include, but is not limited to, determining whether the feature codes "Biz, Mid, Idx, and Sn" coexist in the character string information included in the link of the WeChat document. If not, the browsing link is converted into a permanent link according to a preset rule, and the specific preset rule can be edited in advance according to requirements or completed by means of third-party conversion software; still alternatively, a permanent link is retrieved that enables access to the WeChat article.
205. And if the browsing link of the WeChat article is judged to be the permanent link, extracting the feature code of the WeChat article from the permanent link.
In the embodiment of the present invention, the detailed statement of the step specifically includes the following steps:
firstly, determining the corresponding extraction sequence rule of a plurality of feature codes in a permanent link, and acquiring the element composition rule corresponding to each feature code. For a specific implementation method for constructing the extraction sequence rule and generating the element composition rule, please refer to steps 201 and 202, which are not described herein again.
Secondly, according to the extraction sequence rule and the element composition rule, a regular expression for extracting the feature codes is constructed, the character string information contained in the permanent links is traversed, the character strings matched with the regular expression are searched, the matched character strings are determined as the feature codes of the WeChat articles, and the feature codes of the WeChat articles are extracted.
For example: obtaining a plurality of feature code sequences 'Biz, Mid, Idx, Sn' according to an extraction sequence rule, and obtaining according to an element composition rule: biz is composed of upper and lower case letters, numbers, and equal numbers, Mid is composed of all numbers, Idx is a digit, Sn is composed of a number and a lower case letter.
So a regular expression is constructed:
__biz＝([\w\＝]+)&mid＝(\d+)&idx＝(\d+)&sn＝(\w+)
according to the regular expression, the searching and matching operation of the feature codes can be executed by utilizing the programming language, so that code values respectively corresponding to the feature codes are obtained.
Furthermore, another specific implementation method is also provided for extracting the feature codes of the WeChat articles from the permanent links:
firstly, determining the arrangement order of a plurality of feature codes, such as: the arrangement sequence is as follows: "Biz, Mid, Idx, Sn".
Next, according to the arrangement order, the first character of the feature code whose arrangement order is the first bit and the special character whose arrangement order is the last bit after the feature code are determined.
For example: the permanent links of WeChat articles are as follows
https://mp.weixin.qq.com/s？__biz＝MjM5MzAxNjkwMA＝＝&mid＝2650476042&idx＝2&sn＝c1cf094f228249bdafbade6c1b0b1a92&chksm＝be92d32189e55a3716a44ab6e70fa06671b9ce6a6e451202d21f06d439d04b1b4790f9cec5c4&mpsha re＝1&scene＝1&srcid＝&sharer_sharetime＝1568949234670&sharer_shareid＝4d909ce64954591c250aa10079487374&key＝f0b3b85af89c30e9005cc4c7e62db3a187796970348c3f03b560499254bd584a3d5e4245d9faba0855dc57def84983e8708cf74cfbe7ad7b1cd4fac44ceda96561160bd08380c43545a0a5017e1da1f9&asc ene＝1&uin＝MjkwNDQ1Njc0MA％3D％3D&devicetype＝Windows+7&version＝62060841&lang＝zh_CN&pass_ticket＝IKPy9HeslOQgWOflq4rbHiWSCtajyie ZDJgjrZPjVDQlvYkpE07dEiCSZeu％2BGZ5％2F
Analyzing this permanent link to see: the first character "B" of which the feature code is "Biz" in the first order and the special character "k" in the last order after the feature code "Sn" in the last order are "&", so that the first character and the last character are searched in the permanent link, and when the information containing the following character strings is found, the following are:
biz＝MjM5MzAxNjkwMA＝＝&mid＝2650476042&idx＝2&sn＝c1cf094f228249b dafbade6c1b0b1a92&
secondly, respectively verifying whether a character located at a first preset position behind the first character is a first preset character and verifying whether a character located at a second preset position before the special character is a second preset character;
the first preset position or the second preset position may be determined according to a character number, for example: the position of a certain character in the character string information can be determined by obtaining the character number according to the sorting sequence of the certain character in the character string information.
In an embodiment of the present invention, this verification operation is: in the information of the character string included between the first character and the special character found in the permanent link, it is verified whether the character at the designated position matches with the preset character, specifically, the designated position may be: a certain position is selected after the first character of the first-order feature code is found, or a certain position before the special character is selected after the special character after the last-order feature code is found.
For example: in the following character string information, whether the character verification at the 18 th position after the first bit "biz" "b" is selected is "═ or" and whether the character verification at the 32 th position before the special character "&" after the last bit feature code "sn" is selected is "═ or" is selected.
biz＝MjM5MzAxNjkwMA＝＝&mid＝2650476042&idx＝2&sn＝c1cf094f228249bdafbade6c1b0b1a92&
And finally, if the verification is successful, determining the character string between the first character and the special character as fields contained in a plurality of feature codes, extracting the fields contained in the plurality of feature codes, and matching the fields with preset elements contained in each feature code to obtain each feature code.
Wherein, the element compositions contained in different feature codes are different, for example: biz is composed of three preset elements including upper and lower case letters, numbers and equal numbers, Mid is composed of all number preset elements, Idx is one-digit number preset element, and Sn is composed of number and lower case letter preset element.
In the embodiment of the invention, according to different preset element compositions, in the character string information included between the first character of the searched first-bit feature code and the special character with the arrangement sequence after the last-bit feature code, the field included in each feature code is searched in a matching manner, so that a plurality of feature codes are obtained.
