What are the solutions for the crawler to use proxy IP? for this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

1. Set up a local IP pool and obtain IP usage without interval.

Because there is a minimum frequency of calling IP directly from the API interface of the proxy IP service provider, and some programs have been developed and need to obtain IP without interval. Then you can establish a local IP pool, obtain IP at intervals from the API interface of the proxy IP service provider, then verify and put it into the local IP pool, and then through the API interface of the local IP pool, you can achieve no interval to get the agent IP to work.

2. Use dynamic forwarding to automatically switch proxy IP.

Some people find it troublesome to maintain the proxy IP pool, so they choose to use dynamic forwarding, set a fixed IP and port as the proxy server, and randomly switch the IP for each request.

The thread IP pool of Pinyi http is a unique dynamic forwarding. You can set "how many seconds before IP expires to automatically apply for switching IP", "how many seconds to automatically apply for switching IP after IP acquisition", and so on. You can also directly switch IP by calling API API after each request task is completed.

3. Obtain IP usage directly by calling API API.

Purchase the IP pool from the agent IP service provider, log in to the background management, generate the API interface, connect the API interface to the program code, and obtain the proxy IP by calling the API API to use. However, API APIs generally have a minimum call frequency, such as once per 10 seconds, once per second, 10 times per second, and so on. When calling the API API, you need to follow this rule.

This is the answer to the question about the crawler using agent IP. I hope the above content can be of some help to you. If you still have a lot of doubts to solve, you can follow the industry information channel to learn more about it.
