This article mainly explains the method of using nginx to regularly intercept specified url requests, the content is clear, interested partners can learn, I believe it will be helpful after reading.

Nginx server

Nginx is an excellent web server, which is very efficient in dealing with static files, and its proxy forwarding function is very simple and efficient with other back-end servers.

Location

We know that nginx will parse the request and get the url and other information about the request. We just need to match the url and intercept it.

Matching rule

Location / {if ($request_uri ~ * ^ /\? http (. *) $) {return 404;}}

After such a match, we can intercept all the URLs of the request root directory and similar requests with a parameter of? httpxxx will display 404.

Hotlink protection

Return http code, such as setting nginx hotlink protection:

Location ~ *\. (gif | jpg | png | swf | flv) ${valid_referers none blocked www.80shihua.com www.menghuiguli.com; if ($invalid_referer) {return 404;}}
