har2py

When browsing the web with the Developer Tools open you can record the Network Activities (requests perform by your browser & responses you get from servers). Then you can export all these data into an HAR file (Http ARchive). With har2py you can convert HAR file into valid python code that reproduce the requests perform by your browser.

Installation

Just a simple pip install, i.e. python3 -m pip install har2py

Usage

  1. Navigate the web with your browser while recording your activity. Then save the data in HAR file. Here is an example with Chrome Devs Tools har.gif

  2. Go to the directory where is located the har file you want to convert and type

har2py my_har_file.har

This will generate valid python code base on requests library from my_har_file.har. The generated file will be called my_har_file.py and be located in the same directory of the input file.

Additional arguemnts are describe in the help

I like to develope my own program so I can extend easly by adding new jinja2 templates. In the past I use this other projects and from them I have been ispired to build har2py.
