This article mainly introduces "how Python reptiles break through anti-reptile mechanism". In daily operation, I believe that many people have doubts about how Python reptiles break through anti-reptile mechanisms. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts about "how Python reptiles break through anti-reptile mechanisms". Next, please follow the editor to study!

1. Build a reasonable HTTP request header.

The request header for HTTP is a set of properties and configuration information when you send a request to a network server. Because the browser and the Python crawler send different request headers, the anti-crawler is likely to be detected.

2. Establish a learning cookie.

Cookie is a double-edged sword. You can't have it, let alone without it. The site will track your visits through cookie, and will immediately interrupt your access if you are found to have crawler behavior, such as filling out forms too quickly or browsing a large number of web pages in a short period of time. And the correct handling of cookies, can also avoid many collection problems, it is recommended that in the process of collecting websites, check the cookie generated by these sites, and then think about which crawlers need to deal with.

3. Normal time difference path.

Python crawler should not break the principle of collection speed, as far as possible in each page access time to add a short interval, can effectively help you to avoid anti-crawling.

4. Use proxy IP. For distributed crawlers that have encountered anti-crawlers, using proxy IP will be your first choice.

When it comes to the development history of Python reptiles, it is simply a history of blood and tears in love with anti-reptiles. On the Internet, where there are web crawlers, there is absolutely no place without anti-crawlers. The premise of anti-crawler interception of the website is to correctly distinguish between people and web robots, and to prevent you from continuing to visit by restricting IP addresses and other measures when suspicious targets are found.

At this point, the study on "how Python crawlers break through the anti-crawler mechanism" is over. I hope to be able to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
