Chromote
Simple wrapper to drive Google Chrome from Python using the Remote Debugging Protocol 1.2 API
Installation
$ pip install chromote
API
>>> from chromote import Chromote
>>> chrome = Chromote()
>>> chrome
Chromote(host="localhost", port=9222)
>>> print chrome
[Chromote(tabs=1)]
>>> tab = chrome.tabs[0]
>>> print tab
Google - https://www.google.co.uk/
>>> print tab.url
https://www.google.co.uk/
>>> tab.reload()
'{"result":{},"id":1}'
>>> tab.set_url('https://github.com/chromote')
'{"id":2,"result":{}}'
>>> tab.set_zoom(1.2)
'{"id":1,"result":{"result":{"type":"number","value":1.2,"description":"1.2"},"wasThrown":false}}'
>>> tab.evaluate('alert("Remotey");')Note: Google Chrome needs starting with the --remote-debugging-port=<PORT> option to be controlled remotely.
Remote Browser Control
The remote debugging port binds to localhost only so using chromote with a remote machine like a dashboard/kiosk setup will require tunneling to the machine first.
On the remote machine start Google Chrome:
$ chromium-browser <URL> --incognito --kiosk --remote-debugging-port=9222
On the local machine set up a tunnel to map the remote debugging port to 9222 on localhost:
$ ssh remote-machine -L 9222:localhost:9222
You can then drive your dashboard/kiosk machine remotely to display the content you want.
