With the continuous development of Internet technology, our life and work are closely related to the Internet. The existence of the Internet also makes our life and work pace faster, and web crawlers came into being. When crawling, we need a large number of proxy IPs to help the crawler run. So, is the crawler proxy necessary?
Is it necessary to use a crawler proxy when crawling on the Internet? The answer is actually not necessarily, but the proxy IP must be used in the following situations.
1. When crawling, the crawled website has an anti-crawler mechanism. If you use the IP to repeatedly access the web page, IP restrictions will easily occur and you will no longer be able to access the website. At this time, you need to use a proxy IP.
2. If the workload is large, the crawling speed is fast, and the target server is easy to find, then you need to use a proxy IP instead of an IP before crawling.
3. When crawling website data, the crawler is likely to be blocked. Use proxy IP to replace different IPs, and the other party's website will think it is a new user every time, so there is no danger of being blocked.
Proxy IP is to replace the real IP. Web crawlers are programs that crawl data. Proxy IP is not necessary for web crawlers, but for crawlers, proxy IP is a tool that greatly improves efficiency and facilitates work. Network work pays great attention to speed. Under the premise of speed, tools can improve the quality and efficiency of one's work. This is the significance of proxy IP.
