How to debug by using http request?

Hi! I have set up the PyCharm to Django via the vagrant, I start the Django server successfully, however I can only debug the app by running "Debug" feature. After it done, I can't get into it anymore and I'll need to rerun the debugger again, that's doesn't help when I need to look into a submit form.

how can get into the breakpoint via http GET/POST? Like using xdebug in PHPStorm?

Thanks!
