This article mainly introduces "which scenes must use proxy IP when crawlers". In daily operation, I believe that many people have doubts about which scenes must use proxy IP when crawling. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "which scenes must be used proxy IP when crawlers". Next, please follow the editor to study!
1. When crawling, the website of the crawler has an anti-crawler mechanism.
If you use IP to visit the web page repeatedly, IP is easily restricted. If you are unable to visit the website, you need to act as a proxy IP.
2. When crawling the data of the website, the crawler is equivalent to saying hello to a person repeatedly, and is likely to be blocked.
Replace different IP with proxy IP, the other website thinks it is a new user every time, so there is no danger of blocking.
3. If the dosage is small and the requirement of work efficiency is not high, you don't have to act as an agent ip.
If the amount of work is large and the fetching speed is fast, the target server is easy to find, so you need to use http proxy IP instead of IP before crawling.
At this point, on the "crawler when which scenarios are necessary to use proxy IP" study is over, I hope to be able to solve your 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!
