[BUG] Google News link schema changed?

[moehmeni]

For decoding Google News URLs into their real ones, I am getting error

import base64
import re

# Some url encoding related constants
_ENCODED_URL_PREFIX = "https://news.google.com/rss/articles/"
_ENCODED_URL_PREFIX_WITH_CONSENT = (
    "https://consent.google.com/m?continue=https://news.google.com/rss/articles/"
)
_ENCODED_URL_RE = re.compile(
    rf"^{re.escape(_ENCODED_URL_PREFIX_WITH_CONSENT)}(?P<encoded_url>[^?]+)"
)
_ENCODED_URL_RE = re.compile(
    rf"^{re.escape(_ENCODED_URL_PREFIX)}(?P<encoded_url>[^?]+)"
)
_DECODED_URL_RE = re.compile(rb'^\x08\x13".+?(?P<primary_url>http[^\xd2]+)\xd2\x01')

def prepare_gnews_url(url):
    # There seems to be a case when we get a URL with consent.google.com
    # see https://github.com/ranahaani/GNews/issues/62
    # Also, the URL is directly decoded, no need to go through news.google.com

    match = _ENCODED_URL_RE.match(url)
    encoded_text = match.groupdict()["encoded_url"]
    # Fix incorrect padding. Ref: https://stackoverflow.com/a/49459036/
    encoded_text += "==="
    decoded_text = base64.urlsafe_b64decode(encoded_text)

    match = _DECODED_URL_RE.match(decoded_text)

    primary_url = match.groupdict()["primary_url"]
    primary_url = primary_url.decode()
    return primary_url

# Test the function
url = "https://news.google.com/rss/articles/CBMi2AFBVV95cUxQOHZlbFBOSXZDQTVDNWhibW9nMlUzaWpfbVRZaTNKMXd4VFNtQ2YxQWt2UmtDbHdia2xvbHZDMU03eXVabzFscDdMcHV4aGFnNW1zdU9zakVyaEFmMm1FVDVBRVotdktTbkJBOUFrT3dwNTY5bVNzZWRJQk1RT3l5SnBBeWdXS1laeVpwejQzN3luZjgwVjN0bFB5NkZSM2oxRXJ6Q0ItbDNMUDZJRTdEZXhjbUV1Z3NYMHdXV1hKV3N3YndWOVZjVE9uZlBGNkk0SS1mbTZ3b0Q?oc=5"
result = prepare_gnews_url(url)
print("Result:", result)

AttributeError: 'NoneType' object has no attribute 'groupdict'

I think they changed recently while it was working before.

I got the same error. Not sure if google changed anything. Does anyone have an idea about it?

It seems a solution was figured out here https://gist.github.com/huksley/bc3cb046157a99cd9d1517b32f91a99e?permalink_comment_id=4500912 and @Glyphosate69 wrote a python version. Maybe this can replace the prepare_gnews_url internal function? It's working for our use case at least
