How can I read console log (e.g. messages like ok, connected..) of particular website by using a python coding?

Question

I would like to know how to read console log output for a particular website using Python for the automation.

Currently i am trying to read console data using Selenium, but there is no function that I can use to read my logs, I can read the messages but I cannot read the real time data.

Is there any other library that can I use?

Answer 1

One way, how to do it, is to launch Chrome with: chrome.exe" --enable-logging .

Then you can write a function, which would read chrome_debug.log in real time, for example something like this:

   source = open(r'C:\Users\spolm\AppData\Local\Google\Chrome\User Data\chrome_debug.log' , encoding="utf-8")`
   export=[]
   for line in source:  
     try:
        loadline=line.strip()
        x+=1
        export.append(loadline)

      except UnicodeEncodeError:
        line.strip()
        x+=1
        pass
      except UnicodeDecodeError:
        line.strip()
        x+=1
        pass
  

I hope this helps, if you still looking for the answers after so many years, i can write you full function maybe. (Altrough this is not logging internal object, like JSON files in the console...)

Answer 2

so turns out its not that trivial. didn't have the time to try it, but i may have found some options:

option A

1. get console content with JS

2. run JS with webdriver: driver.execute_script(script,*args)

3. get value back to python from selenium

option B

chrome devtools API with selenium:

selenium side

DevTools side

hope this will help, good luck !
