How to change response body with Charles?

问题:

I am using Charles (http://www.charlesproxy.com) to debug my HTTP requests and now I run into an issue where I am receiving json response which I need to edit to see how my app behaves.

I was looking at Rewrite option but can't really figure out how to change it. Ideal would be to load whole response from disk.

Any ideas how to accomplish this? Thank you.

The Map Local tool is probably what you're looking for. Access via menu Tools | Map Local.... Note, you may need a corresponding rewrite rule (Tools | Rewrite...) to ensure the mime type of your response served from disk and the type your application is expecting. But recent versions of Charles may set the type automatically.

Enable breakpoints, then change response. You should press continue/send request to send it before tweak response.

As was mentioned Charles Proxy(4.2.8 version) allows you to change response body using different approaches:

1. Map Local Tool ⌘ command + ⌥ option + L - Use local files to serve remote location
2. Map Remote Tool ⌘ command + ⌥ option + M - Modify the request location to map one remote location to another
3. Rewrite Tool ⌘ command + ⌥option + R - Modify requests and responses as they pass through Charles
4. Breakpoints Tool ⌘ command + ⇧ shift + K - Intercept and edit requests and responses before they are sent and received
