What are the ways of crawler IP agent

This article mainly introduces the crawler IP agent ways, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

1. Obtain IP usage directly by calling API, and purchase IP from IP proxy service provider.

For example, IPIDEA contains global dynamic and static IP, login background management, you can generate API interface, connect the API interface in the program code, and obtain the use of proxy IP by calling API interface. However, the API interface has a minimum call frequency, such as 10 seconds, 1 second, 1 second, and so on. You need to follow this rule when calling the API interface.

2. Set up a local IP pool to obtain IP usage without interval.

Because the frequency of getting IP directly from the interface of a proxy IP service provider is the lowest, there are also several programs that can get IP uninterrupted. Then you can set up a local IP pool, get the IP at intervals from the API interface of the proxy IP service provider, then validate and put it into the local IP pool, and then obtain the proxy IP without interval through the API interface of the local IP pool.

3. Use dynamic forwarding to automatically switch proxy IP.

Some people think that maintaining the proxy IP pool is troublesome, so they choose to use dynamic forwarding, set the fixed IP and port as the proxy server, and switch the IP at random each time.
