>>> 

Perform HTTP requests.

You can inspect the HTTP requests directly in your web browser at http://localhost:4909.

script

You can trace all the HTTP requests performed by a script

pyhttpdbg --script filename.py [arg1 --arg2 ...]

pytest

You can trace all the HTTP requests performed during your tests

pyhttpdbg -m pytest [arg1 --arg2 ...]

note: the HTTP(S) requests are not recorded if the tests are executed in parallel using plugin like xdist.

module

You can trace all the HTTP requests performed by a library module run as a script using the -m command line argument.

For example, you can view which HTTP requests are performed by pip when you install a package.

pyhttpdbg -m pip install httpdbg --upgrade

Initiators

An initiator is the function/method that is at the origin of the HTTP requests. By default, we already support some packages but you can add your own initiators.

To add a new package in the list of initiators, you can use the -i command line argument:

pyhttpdbg -i api_client_pck --script my_script.py

You can use any package as an initiator, this is not limited to HTTP requests.

Already supported packages

your_package	yes, with the arg -i your_package

  --console             run a python console (default)
  --module MODULE, -m MODULE
                        run library module as a script (the next args are passed to pytest as is)

web interace

Clic on the ⚙ button on the top right of the page.

Some options are available:

• Hide the netloc in the url
• Hide the initiator rows

To keep your configuration, bookmark the page with the full search query.

Fox example, if you want to hide the initiator rows by default, the url will be:

http://localhost:4909/?hi=on

web interface

All the requests recorded are available on the web interface.

The requests:

• are still available in the web page even if the python process stopped (except if you force quit before the requests have been loaded by the web page).
• are automatically cleaned if a new execution is detected.
