监视Java应用程序的流量

Question

I have a console Java application. Some of HTTP requests return error codes, and I want to debug them. In browser I can watch POST requests in detail, but how can I manage to do it in Java application?

Answer 1

In your getHttpRequest (or whatever it is called) method print incoming request. That would be the simplest solution.

More sophisticated - you can extend standard classes which work with requests and modify methods which get requests to print them first.

Answer 2

Try Wireshark or fiddler. The both sniff traffic in a similar manner as firefox and various browsers do now.
