This article is about web crawlers how to set IP cycle switching, the editor feels very practical, so share with you to learn, I hope you can learn something after reading this article, say no more, follow the editor to have a look.

Technically, you can set the IP switch in a web crawler in any of these steps.

1. You need a set of IP addresses and create a list in your agent software and apply the rotation algorithm, the most common of which is the round robin algorithm.

You need a set of IP addresses and create a list in your agent software and apply the rotation algorithm, the most common of which is the round robin algorithm. However, you can apply different other logic, such as the least join algorithm or even the ordered set algorithm.

two。 Learn how to set up a proxy server, and then learn about the rotation algorithm.

Depending on your software skills, you may need to know how to set up a proxy server first, and then understand the rotation algorithm. In many cases, you need to be aware that the bandwidth of the agent is limited, so your software should also be careful not to exceed the allowed bandwidth of a given IP, otherwise your network will be out of control.

After all, setting up IP rotation for web crawlers is a process that involves many other factors, such as ensuring that agents are valid for a given Web site. Suppose your web crawler is crawling a list of Amazon product pages for your next generation shipping research project. Amazon is based on IP blocking, so you don't want to rotate over and over the same IP, otherwise you won't benefit from it.

The above is how the web crawler sets the IP cycle switch, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
