httpdbg is a tool for Python developers to easily debug the HTTP(S) client requests in a Python program.
To use it, execute your program using the pyhttpdbg command instead of python and that's it. Open a browser to http://localhost:4909 to view the requests:

pip install httpdbg
Open an interactive console using the command pyhttpdbg.

>>> Perform HTTP requests.
You can inspect the HTTP requests directly in your web browser at http://localhost:4909.
You can trace all the HTTP requests performed by a script
pyhttpdbg --script filename.py [arg1 --arg2 ...]You can trace all the HTTP requests performed during your tests
pyhttpdbg -m pytest [arg1 --arg2 ...]If you use the pytest-xdist plugin to execute your tests in parallel, then you must install the pytest-httpdbg plugin if you want to trace the requests done by the pytest workers.
pip install httpdbg[pytest]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 hookdns --upgradeAn 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.pyYou can use any package as an initiator, this is not limited to HTTP requests.
| packages | status |
|---|---|
| requests | supported |
| urllib3 | supported |
| httpx | supported |
| aiohttp | supported |
| pytest | supported |
| your_package | yes, with the arg -i your_package |
No configuration is necessary to start but some few settings are available for particular use.
usage: pyhttpdbg [-h] [--host HOST] [--port PORT] [--version] [--initiator INITIATOR] [--keep-up | --force-quit]
[--console | --module MODULE | --script SCRIPT]
httdbg - a very simple tool to debug HTTP(S) client requests
options:
-h, --help show this help message and exit
--host HOST the web interface host IP address
--port PORT, -p PORT the web interface port
--version, -v print the httpdbg version
--initiator INITIATOR, -i INITIATOR
add a new initiator (package)
--keep-up, -k keep the server up even if the requests have been read
--force-quit, -q stop the server even if the requests have not been read
--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)
--script SCRIPT run a script (the next args are passed to the script as is)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
- Hide the tags
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
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.
