Summary of how charles modifies requests and responses (multiple pictures are very detailed)

The basic usage of charles will not be repeated. This article mainly summarizes several ways to modify requests and responses.

The test request used in this article is the local interface: http://sunset.com:8000/file/avatar/goods-001.jpg?name=test&age=20

1. Modify the request message through compose, which is similar to postman's simulated request

   Select the request intercepted by charles, right click –>compose

   
   

   As shown in the figure: Label 1 can see the parameters of this request, which can be modified here; Label 2 can add and delete query parameters; Label 3 executes the modified request;

2. Modify the request and response through rewrite

   Click the menu tools–>rewrite to open the Rewrite Setting window

   
   
   

   Then we test the request in the browser

   
   The test only modifies the response body data, and this rewrite can also modify other types of data such as the response status code.

3. Rewrite the response by mapping local files

   Select the request intercepted by charles, right click and select save response, which can be saved in .json format
   

   Open the file you just saved and modify the data inside

   

   Right-click the request again, select map local, and open the configuration window

   
   

   Then open the test in the browser, you can see the content we just modified.

   

4. Modify requests and responses through breakpoints

   Select the request intercepted by charles, right click and select breakpoints
   

   Then use the browser to initiate the request again

   

   After clicking execute, you can see the breakpoint and go to the response editor

   

   After performing the operation, you can see that the response on the browser side has changed
