Chrome扩展程序拦截对特定端点的Ajax请求以修改表单数据

Question

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?

Answer 1

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.
