Use wfetch to view HTTP request and response packets

Now we have this wfetch, but it is much easier. Of course, it also supports connection to localhost, and is the default. Wfetch allows us to select various request methods and specify the HTTP protocol version. Below is my previous articleArticleThe HTTP connection information.

In the advanced request column, you can select the corresponding request header structure, message body or request, enter the corresponding information, and press enter to start the connection and obtain the HTTP request and response packets. For example:
