This article introduces the relevant knowledge of "explaining the importance of the agent ip pool to the crawler". In the operation of the actual case, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

You can see how important the proxy ip pool is to the crawler through the following two points:

1. Solve the problem that access to the web page is prohibited to achieve the purpose of grabbing information normally.

In the process of crawlers, we often encounter many websites using anti-crawling technology, or because the intensity and speed of collecting website information is too high, which puts too much pressure on each other's servers, because you have been using the same agent.

When IP crawls this web page, it is very likely that IP will be prohibited from accessing the web page, so basically people who do crawling can not avoid the problem of IP, and need a lot of IP to achieve the purpose of constantly switching their IP addresses to achieve the purpose of crawling information normally.

two。 Solve the problem that the technical content is too high and the consumption cost is too high, and meet the excessive demand of ip.

Generally speaking, crawler users do not have the ability to maintain their own servers, or to solve the problem of proxy IP on their own, first, because the technical content is too high, second, because the cost is too high, of course, there are many people will put some free proxy IP on the Internet, but from the practical, stability and security considerations, it is not recommended that you use free IP. Since the agent IP published online is not necessarily available, it is likely that you will find that IP is not available or invalid during use. So now there are many proxy servers on the market, basically all of which can provide proxy IP services for you. Nowadays, it can be said that it is a very common requirement for crawlers to avoid being attacked by anti-crawling programs. When doing web crawlers, there is a large demand for proxy IP. Because in the process of crawling website information, many websites have made anti-crawler strategy, maybe every IP has done frequency control.
