Breaking value in Chrome cookie for auth

[scrimshander]

Just had to refresh my auth headers after many many months, and kept getting a missing key bug in the cookie, pasted from Chrome/developer tools.

Turns out this key/value:

YT_CL={\"loctok\":\"APLXd64Le9G-vJVqzKjy-OsOVBh6NfU2xKnD6awbKB9lJUXzvHGMuNBmjOpK5q_K xVqxgIRcjI_FC27tj-wmyhvUgW8g4A\"};

Was breaking the cookie parser (perhaps because of the quotes or the embedded dict). Removing it from the headers text fixed the issue.

This seems strange, your cookie value is not escaped properly. Can you please paste the original YT_CL headers from Chrome? Excluding the identifying Cookie entry and any private information in there, it's not relevant here.

Same issue here - in the Chrome DevTools, the cookie looks like:

YT_CL={"loctok":"stringofchars"};

Before, I was receiving the error: "Exception: Your cookie is missing the required value __Secure-3PAPISID". But after removing the "YT_CL" cookie, it started to work again.

It seems to be an issue with the way SimpleCookie loads raw data. It does not seem to handle quotes properly.

>>> from http.cookies import SimpleCookie
>>> SimpleCookie('a1={b:c};')   
<SimpleCookie: a1='{b:c}'>
>>> SimpleCookie('a1={"b":c};')
<SimpleCookie: >
>>> SimpleCookie('a1={\"b\":c};') 
<SimpleCookie: >
