A tutorial for blocking specific user agents in Nginx _nginx

The modern internet has spawned a vast array of malicious robots and web crawlers, such as malware bots, spam programs, or content scrapers, which have been surreptitiously scanning your site, doing things like detecting potential web sites, harvesting e-mail addresses, or simply stealing content from your site. Most robots can be identified by their "User agent" signature string. As a first line of defense, you can try to prevent these malware

interfaces. The object for each proxy class associates an implementation of the Invocationhandler interface that represents the internal processing logic. When a user invokes a method in the interface that the proxy object proxies, the message is passed to the Invocationhandler invoke method. In the parameters of the Invoke method, you can get to the proxy object, the method object corresponding to the methods, and the actual parameters of the call.

Python implements crawling of available proxy IPs

In the implementation of the crawler, the dynamic set proxy IP can effectively prevent anti-crawler, but for ordinary crawler beginners need to test the proxy IP on the agent site. Because the manual test process is relatively cumbersome, and repeated useless process so write code to achieve dynamic crawling of available proxy IP. The dynamic proxy IP is stored in a JSON file for subsequent project crawlers, but the proxy IP that is crawled is free IP, so there may be a situation where crawling
