[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.

[0041] The conventional website cloning tool cloning method is to download the directory structure of the website to the local to build all directories in a recursive manner. However, this method can only obtain static HTML pages, pictures and other files of the website. In another existing website cloning technology, static files are parsed to obtain more links, but currently, front-end technologies mostly use dynamic scripts to generate pages to display the pages. The traditional page cloning tool cannot obtain the new page generated by the jump of the request link generated by the JavaScript script. In addition, if the same link has different request parameters, the website displays the response page according to different request parameters, and the traditional website cloning tool cannot clone the pages generated by different parameters, resulting in that the cloned website is not comprehensive and complete. Therefore, the present application provides a website cloning method which can generate corresponding response pages according to different requests when cloning a website to achieve the purpose of completely cloning the website.

[0042] The embodiment of the present application discloses a website cloning method, as shown in Figure 1 The method comprises the following steps:

[0043] Step S11: creating a blank window in an interfaceless browser through a preset crawler program and loading a target website.

[0044] In the embodiment, the interfaceless browser is a browser without a graphical user interface, that is, a headless browser. A blank window is created in the interfaceless browser through a preset crawler program, and the website address of the target website is loaded through the blank window to obtain the webpage of the target website. Through the above technical solution, the target website is crawled through the crawler program, so that the static element information and the jump page information in the target website can be crawled subsequently to realize complete cloning of the target website.

[0045] Step S12: obtaining the current page information of the target website to obtain the static element information in the current page, and saving the static element information into a preset database.

[0046] In the embodiment, the current page of the target website is acquired, elements in the current page are parsed, static element information in the current page is acquired, and the static element information is saved into a preset database. It should be noted that the static element information includes but is not limited to static element connection, static element request method and static element request parameter; and the preset database is a database for storing information crawled by the target website. By the above technical solution, the static element information is saved into the preset database, so as to clone the target website through the static element information.

[0047] Step S13: Crawling jump page information corresponding to the current page of the target website, and saving the jump page information into the preset database.

[0048] In the embodiment, the jump page information corresponding to the current page of the target website is crawled, and the jump page information is saved into the preset database. It should be noted that the jump page information includes but is not limited to jump page link, jump page request method and jump page request parameter. By the above technical solution, the jump page information corresponding to the current page of the target website is dynamically crawled, and the jump page information is saved, so as to send a request to the target website through the jump page information in the future.

[0049] Step S14: Sending a request to the target website according to the jump page information in the preset database, receiving response information returned by the target website, and then saving the response information corresponding to the jump page information into the preset database, so as to construct a cloned website of the target website according to data in the preset database.

[0050] In the embodiment, the request is sent to the target website according to the jump page information in the preset database, specifically including: reading the preset database to obtain the web link, request method and request parameter of the jump page corresponding to the jump page information; and sending a request to the target website according to the web link, request method and request parameter of the jump page. Further, the response information returned by the target website is received, and the response information corresponding to the jump page information is saved into the preset database.

[0051] In a specific embodiment, when a request message for a clone website is acquired, the corresponding response information is found in the preset database according to the webpage link, the request method and the request parameter corresponding to the request message, and the response information is replied to the sender of the request message. Through the above technical solution, the website simulation process is started, when the request initiated by the client is received, the response information corresponding to the request can be obtained by querying the preset database according to the link, the request method and the request parameter and the response information is replied to the request sender, so as to achieve the purpose of completely cloning the target website.

[0052] It can be seen that, in the website cloning process of the embodiment, the target website is first crawled by the preset crawler program to obtain the current page information of the target website and obtain the static element information in the current page through the current page information, then the jump page information in the current page is crawled, the jump page information is sent to the target website according to the obtained jump page information, and the response information returned by the target website is received, and the response information corresponding to the jump page information is saved in the preset database, so as to construct the clone website of the target website through the information in the preset database. Therefore, in the website cloning process of the present application, all element information of the target website is crawled through the dynamic crawler, and the jump page dynamically generated by the front end can also be crawled and the response information returned by the target website can be obtained, so that the problem that the new page generated by the jump of the request link dynamically generated by the JavaScript script cannot be cloned by parsing and obtaining the static elements of the target website in the prior art is solved in the website cloning process, thereby achieving the purpose of completely cloning the target website. In summary, the present application can generate corresponding response pages according to different requests to achieve the purpose of completely cloning the website.

[0053] Referring to Figure 2 The embodiment of the present application discloses a specific website cloning method, which is further described and optimized compared with the previous embodiment.

[0054] Step S21: creating a blank window in the interfaceless browser through the preset crawler program and loading the target website.

[0055] In the embodiment, when the preset crawler program is started, the puppeteer in the preset crawler program is called to start an interfaceless browser, and a blank window is created to load the target website address to be crawled. Through the above technical solution, the target website is crawled by the crawler program, so that the static element information and the jump page information in the target website can be crawled in the subsequent process to realize the complete cloning of the target website.

[0056] Step S22: Obtain the current page information of the target website to obtain the static element information in the current page, and save the static element information into a preset database.

[0057] In the embodiment, the current page information of the target website is obtained to obtain the static element information in the current page, and the static element information is saved into a preset database, specifically including: obtaining the current page information of the target website through a web page attribute interface in the preset crawler program; parsing the elements in the current page according to the current page information, and extracting the label field of the static element link in the current page to obtain the static element information, and then saving the static element information into a preset database. In a specific embodiment, after the browser loads the web page, the puppeteer can obtain the page information through the page attribute, parse all elements in the page, extract the label field of the static element link, and store the web page link, request method and request parameter information of the static element into the database.

[0058] Step S23: Crawl the first jump page information and the second jump page information corresponding to the current page of the target website, and save the first jump page information and the second jump page information into the preset database.

[0059] In the embodiment, the first jump page information corresponding to the current page of the target website is crawled and saved into the preset database, specifically including: intercepting the active jump request sent by the interfaceless browser through a preset hijacking function; crawling the first jump page information in the target website corresponding to the active jump request, and saving the first jump page information into the preset database. The second jump page information corresponding to the current page of the target website is crawled and saved into the preset database, specifically including: listening to the jump trigger event in the current page, and simulating the jump trigger event through a preset interface in the preset crawler program; crawling the second jump page information in the target website corresponding to the jump trigger event, and saving the second jump page information into the preset database. Specifically, a hook hijacking function is set to intercept the active jump request sent by the browser, to prevent the page from being accidentally jumped or closed. The intercepted request also needs to be crawled again for the first jump link. After the function is hijacked, the first jump web page link, request method and request parameter information are inserted into the database through the self-defined interface; all trigger events contained in the web page are listened to, the trigger events are simulated through the puppeteer interface, the changes of the web page after the events are triggered are collected, and if the event triggers the jump to a new web page, the content triggering the event is inserted into the database as the second jump web page link, request method and request parameter information.

[0060] Step S24: sending a request to the target website according to the first jump page information and the second jump page information in the preset database, receiving response information returned by the target website, and then saving the response information corresponding to the jump page information in the preset database to construct a cloned website for the target website according to data in the preset database.

[0061] It can be seen that in the embodiment, the current page information of the target website is obtained to obtain static element information in the current page, and the first jump page information and the second jump page information corresponding to the current page of the target website are crawled to obtain information corresponding to dynamic jump pages in the target website, all requests and response information of the website are obtained by using a dynamic crawler, various mouse and keyboard events in the website are automatically triggered to obtain dynamic web page information, and all requests and responses are only saved in a database file, so that a large number of folders generated by a traditional website cloning tool are avoided, file management is facilitated, and the purpose of completely cloning the target website is achieved.

[0067] It can be seen that, in the website cloning, the target website is first crawled by the preset crawler program to obtain the current page information of the target website, and the static element information in the current page is obtained through the current page information, then the jump page information in the current page is crawled, the jump page information obtained is used to send a request to the target website and receive response information returned by the target website, and the response information corresponding to the jump page information is saved in the preset database, so as to construct the cloned website of the target website through the information in the preset database. Thus, in the website cloning, all element information of the target website is crawled through the dynamic crawler, and the jump page dynamically generated by the front end and the response information returned by the target website can also be crawled, so that in the website cloning, the problem that the static file is parsed and the static element of the target website is obtained in the prior art, and the new page generated by the jump of the request link dynamically generated by the JavaScript script cannot be cloned, so that the purpose of cloning the target website completely is achieved.
