Chrome extension intercept ajax requests to specific endpoints to modify form data












0















Is it possible to modify ajax requests to a specific endpoint on a webpage?



For example, all requests on wwww.example.com that go to /should_intercept will trigger a function that can modify the form data? If so, how can I intercept specific requests?

          Yes, you can do it.



          You can create a Proxy on XMLHttpRequest and inject it as a script into the page, to override original XMLHttpRequest. And inside your implementation of the Proxy, you will be able to handle requests as you want.

          • You could look into this example how to implement a Proxy. For the client script, it just injection script tag into the page body with this code, and it will execute inside of the page context.
