Repeat package tool/repeat
Charles lets you choose a request and repeat, useful when testing backend interfaces;
Charles resends the request to the server and displays the response as a new request.
If you make backend changes and want to test them, with charles you don't need to repeat the request in the browser (or other client), charles can be done very conveniently.
Especially if the re-creation request needs to pass a number of parameters (such as in the game to get points, such as when filling out a large list of form requests), this will save a lot of effort.
The repetition of the request is done inside Charles, so you can't view the response in a browser or other client;
The response is only visible to Charles.
