Analyze the structure of the website
We need to get the Gaoni agent, press F12 to open the developer tool
The data we need to get above is the ip address, port and type. As you can see, these data are all in one tr tag, but there are two different tr tags, so we can use regular expressions and use the separated html structure to match the whole content first, and then match the important information. Finally, put him like this {'https':' https://ip: port'} into the list, and finally get an ip at random, and then you can first judge whether it is useful, and then use it as the proxy ip for your project at this time. The method to determine whether to use it is to casually take a Baidu to get another website, plus the agent ip to send a get request to see if the return code of status_code () is 200. it's fine, like the following.

Code part
1. Match the data and select the data to store in the list
