How to judge whether the API extraction link is normal

Whether the API extraction link is normal and whether the proxy IP can be extracted normally. Many software sets incorrectly in the first step, and the IP cannot be extracted at all, or the API return format does not meet the requirements. There are also many friends whose code handles the IP delimiter incorrectly. Some users use the proxy IP as the first one to succeed each time, and all subsequent uses fail. After repeated investigations, they found that the separator was not handled correctly. So how to judge whether it is the problem of API extraction link? It is actually very simple. Copy the API extraction link to the browser bar and press Enter to open, and you can see the result:
1. The webpage cannot be opened, the API has a problem;
2. Normal Return the IP and check whether the format meets the requirements;
3. Abnormal return due to other reasons, such as missing parameters, or extraction too fast, etc.
