1. Use the interface.

If you get a free proxy IP, you can use the ProxyGetter API to obtain the latest proxy IP; from a free proxy website. If you use a paid proxy IP, generally speaking, there are certain restrictions on how much API is provided in order to obtain IP, such as how much to extract each time and how many seconds to extract.

2. To store the IP database, it is recommended that you select SSDB to store the acquired proxy IP.

The performance of SSDB is very good, basically the same as Redis, Redis is a memory type, capacity problem is a weakness, and memory cost is too high. In view of this shortcoming, SSDB uses hard disk storage, uses Google's high-performance storage engine LevelDB, uses high-capacity processing, and optimizes performance to reach Redis level.

3. Check the timeliness of IP.

Agent IP is timely, whether it is a completely free agent IP or a paid agent IP, there is a validity period, which will expire after the validity period, so its validity must be tested. Set up a timing detection plan, regularly check the effectiveness of the proxy IP, and remove invalid IP and high latency IP. IP is used to obtain the IP in the IP pool, and when the IP in the IP pool is lower than a certain threshold, the new IP is realized through this interface.

4. IP is called by the external interface, and an external interface must be designed to obtain the proxy IP pool.

Use this interface to read IP from the IP pool for use by web crawlers. The function of proxy IP pool is very simple and can be done with Flask. Its function can be an interface, such as get/delete/refresh, which is easy for crawlers to use directly.
