Usage

Download BrowserMob Proxy

Assuming that you don't have BrowserMob Proxy downloaded, then first thing we probaly need to download it and save it to your /tmp directory (Assuming /tmp has write access). It should do be done by

    $ browsermob-cli setup

Now, you should have browsermob-proxy binary downloaded. We need to keep in the /tmp directory itself.

Generate HAR file for any URL

We can generate HAR data for any url e.g (AOL website) by running

     $ browsermob-cli show_har http://www.aol.co.uk

After running this command, you should see following

• Firefox Opened up with AOL homepage within BrowserMob proxy
• All request URLS printed on console
• HAR file saved to /tmp/traffic.har
• HAR data parsed in YAML format and saved to /tmp/traffic.yml
• WEBrick server starts and open up HAR data to preview

Generate HAR file for any URL when user clicks on the page

We can generate HAR data for any url e.g (BBC website) and passing CSS Selector where you want to click

     $ browsermob-cli show_har_click http://www.bbc.co.uk/blogs --locator ".rsp-img"

After running this command, you should see following

• Firefox Opened up with BBC blog homepage within BrowserMob proxy and clicked on image
• All request URLS printed on console
• HAR file saved to /tmp/traffic.har
• HAR data parsed in YAML format and saved to /tmp/traffic.yml
• WEBrick server starts and open up HAR data to preview
