VistasExtract media files from cache using Selenium
I'm trying to download some videos from a website using Selenium.
Unfortunately I can't download it from source cause the video is stored in a directory with restricted access, trying to retrieve them using urllib, requests or ffmpeg returns a 403 Forbidden error, even after injecting my user data to the website.
I was thinking of playing the video in its entirety and store the media file from cache.
Would it be a possibility? Where can I find the cache folder in a custom profile? How do I discriminate among files in cache?
EDIT: This is what I attempted to do using requests
import requests
def main():
s = requests.Session()
login_page = '<<login_page>>'
login_data = dict()
login_data['username'] = '<<username>>'
login_data['password'] = '<<psw>>'
login_r = s.post(login_page)
video_src = '<<video_src>>'
cookies = dict(login_r.cookies) # contains the session cookie
# static cookies for every session
cookies['_fbp'] = 'fb.1.1630500067415.734723547'
cookies['_ga'] = 'GA1.2.823223936.1630500067'
cookies['_gat'] = '1'
cookies['_gid'] = 'GA1.2.1293544716.1631011551'
cookies['user'] = '66051'
video_r = s.get(video_src, cookies=cookies)
print(video_r.status_code)
if __name__ == '__main__':
main()
The print() function returns:
403
This is the network tab for the video:

Regarding video_r = s.get(video_src, cookies=cookies) Have you try to stream the response ? which send correct byte-range headers to download the video. Most websites prevent downloading the file as "one" block.
with open('...', 'wb') as f:
response = s.get(url=link, stream=True)
for chunk in response.iter_content(chunk_size=512):
if chunk: # filter out keep-alive new chunks
f.write(chunk)
You can send a head request before if you want, in that way you can create a progress bar, you will retrieve the full content length from header.
Also a 403 is commonly use by anti-bot system, may be your selenium is detected.

You blocked because you forgot about headers. You must use:
s.get('https://httpbin.org / headers', headers ={'user-agent': <The user agent value (for example: last line of your uploaded image)>})
or:
s.headers.update({'user-agent': <The user agent value (for example: last line of your uploaded image)>})
before sending a request
