Embodiment 1
[0042] Embodiment 1, method for detecting and updating website asset inactivation based on HTTP response, such as figure 1 shown, including the following steps:
[0043] 1), obtain a domain name of a website to be detected from the list of supervised website assets; perform step 2);
[0044] 2) Request the domain name from the server to obtain the HTTP (HyperText Transfer Protocol, hypertext transfer protocol response) status code. After experimental verification, the status codes classified as inactive status codes are 307, 400, 421, 422, 502, 503, 504, 550, 552, and 553, when the inactivation status code is returned when the request is made to the server, the website is in an inactivation state such as closing or request failure. Judging whether it belongs to the deactivation status code, if it belongs to the deactivation status code, proceed to step 11), if it does not belong to then perform step 3);
[0045] 3), 301, 302 redirection codes indicate that the website may re...
specific Embodiment 1
[0065] The following is an embodiment where the website is not deactivated and not redirected (i.e. normal conditions), and the execution process is as follows:
[0066] (1) Obtain a domain name of a website to be detected from the list of supervised website assets: www.abc.com.cn;
[0067] (2) The HTTP status code obtained from the request to the website is 200, and it is judged that 200 does not belong to the deactivation status code, and does not belong to the redirection status code;
[0068] The status of the website is normal, no deactivation update is required, and the process ends.
specific Embodiment 2
[0070] The following is an example of website redirection, and the execution process is as follows:
[0071] (1) Obtain a domain name of a website to be detected from the list of supervised website assets: www.123.com.cn;
[0072] (2) The HTTP status code obtained from the request to the website is 301, and 301 is not an inactivation status code;
[0073] (3) Determine that 301 is a redirection code, request HTTP and get a response, and obtain the domain name of the redirected website: www.456.com.cn;
[0074] (4) The website domain names www.456.com.cn and www.123.com.cn are inconsistent;
[0075] (5) Crawl www.456.com.cn's website titled "Security Test" and sponsor "Huayin Security Co., Ltd." These keywords are close to the website title "Website Security Test Platform" and sponsor recorded on the original website "Huayin Security Co., Ltd." approached;
[0076] (6) Update the supervised website asset list from www.123.com.cn to www.456.com.cn, update the website title wi...
