Question

Is there any way to log http requests/responses using Selenium Webdriver (firefox)?

I guess it's possible to drive web traffic through proxy and log it, but maybe there is more simple "internal" selenium solution?

Asked this question on #selenium channel:

you will need to proxy it to capture the requests

so, looks like only way to setup proxy for it.

Answer 1

Now year 2021, answer is: YES.

you can use the new lib: selenium-wire

How to use selenium-wire

install

pip install selenium-wire

change code

change from

from selenium import webdriver

to

from seleniumwire import webdriver

add your code

after driver.get(yourUrl), add:

# Access requests via the `requests` attribute
for request in driver.requests:
    if request.response:
        print(
            request.url,
            request.response.status_code,
            request.response.headers['Content-Type']
        )

can got your expected request and response.

Answer 2

No, WebDriver doesn't have any methods to examine or modify the HTTP traffic occurring between the browser and the website. The information you've already gotten from the Selenium IRC channel (likely even from a Selenium committer) is correct. A proxy is the correct approach here.
