Analyzing HAR files

HAR is a quasi-standardized JSON format for saving HTTP traffic. It is supported by many HTTP-related tools, including developer consoles of some Web browsers.

HTTPolice can analyze HAR files with the -i har option:

$ httpolice -i har myfile.har

However, please note that HAR support in major Web browsers is erratic. HTTPolice tries to do a reasonable job on files exported from Chrome, Firefox, and Edge, but some information is simply lost.

If HTTPolice fails on your HAR files, feel free to submit an issue (don’t forget to attach the files), and I’ll see what can be done about it.
