This article is about how a proxy IP pool can be established. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

1. Get the proxy ip interface.

Generally speaking, the API that provides IP is limited. For example, each time, for example, a few are extracted at a time, with an interval of several seconds. If you are crawling a free proxy IP, you can use the ProxyGetter interface to crawl the latest proxy IP from the free proxy source site, or you can extract it from the purchased proxy IP.

2. Establish the database.

To save the obtained proxy IP, it is recommended that you choose SSDB. SSDB has outstanding performance, which is basically equivalent to Redis. Redis is a type of memory with weak capacity and high memory cost. For this weakness, SSDB uses hard disk storage, and Google uses high-performance storage engine LevelDB, which is suitable for big data to handle and optimizes performance to the Redis level.

3. Agent IP check.

Agent IP has timeliness, set time inspection plan, verify the validity of proxy ip, delete invalid ip, delete high delay ip, and warn that when the ip in ip pool is below a certain threshold, the new ip can be obtained through the proxy ip acquisition interface.

4. Proxy IP pool external interface.

With the proxy for the IP pool, you also need to design an external interface through which the IP from the IP pool is called into the crawler. The function of proxy IP pool is relatively simple, and you can use Flask. This function provides get/delete/refresh and other interfaces for the crawler, making it easier for the crawler to use directly.
