This article mainly introduces how to use proxy IP in the crawler, 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. Establish a local IP pool and obtain IP without interval

Because obtaining IP directly from the API interface of a proxy IP service provider has a minimum call frequency, some programs have been developed and need to obtain IP without interval. 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.

2. 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. Interesting thread IP pool is a unique dynamic forwarding. You can set the automatic application for switching IP before the expiration of IP, the number of seconds to automatically apply for switching IP after IP acquisition, and so on. After each request task is completed, you can directly switch IP by calling the API API.

3. Obtain IP usage directly by calling API API

Purchase the IP pool from the proxy IP service provider, log in to the background management, generate the API interface, connect the API interface to the program code, and obtain the use of the proxy IP by calling the API interface. However, the API interface usually has a minimum call frequency, such as every 10 seconds, every 1 second, every 10 seconds, and so on. You need to follow this rule when calling the API interface.
