No option to wait until page is loaded

[maaaaz]

Python 2 compatibility does not have to maintained, particularly for a specific feature.

Hello, try to play with --ajax-max-timeouts.
And take a look at this

My use case is Icingaweb2 (Icinga2 web front end), the page loads, but the screenshot is taken so quick the alerts are not loaded:

It would be nice to have the engine load the page, and allow the scrape request to wait X seconds.

Hello!
--ajax-max-timeouts works only for PhantomJS, isn't it?

I have the same problem. Some pages don't load because screenshots is done too fast. (i'm using -r chromium)
It is good idea to add a request waiting. If you add this function i will be very grateful.
Thank you.

I'm working on a fork that will use the Devtools protocol to manage the screenshot process for Chromium based browsers such as Chrome. I've ran into the same issue in the past, specially with those sites that have some sort of WAF protection that is not very agressive, but it requires to wait for at least 5 seconds to render the requested page.
With the aid of the Devtools protocol running the browser in remote debugging mode, some of the PhantomJS exclusive functions can be implemented in Chrome, such as image cropping, screenshot delay, http headers and cookies control, etc, etc. The only caveat I see with this implementation is the use of the "websockets" lib needed to interact with the browser, because it requires python 3, and it will break backwards compatibility with python 2 :(
Do you guys know any websocket library compatible with python 2?

Awesome :)

Hello @maaaaz .
Here is my suggested approach to implement the Devtools protocol in the script.
It's not complete yet, and there are a lot of tests to run, but it will give you a general idea of where this is going:
Running Chrome / Chromium in remote debugging mode: Line 325
Screenshot function (currently supporting PDF, JPG and PNG formats, image quality for JPG and screenshot delay): Line 765
I'll be implementing other functions from the PhantomJS renderer and then I will start the heavy testing, but for now I will be uploading new changes to the experimental branch.
Regards ;)
Edit:
Added --crop option support: Line 950
Edit:
Added --cookie option support: Line 828

Added --header option support: Line 815

Dear maaaaz

Really looking forward for the implementation of this feature - hopefully you'll be able to add it soon :)
