Can't login in PixivUtil2

[Ouxhi]

I'm using the latest release of PixivUtil2 (v20240703). As of today, when I try to launch PixivUtil2, I get an error message:

Trying to log in with saved cookie
Logging in, return url: https://www.pixiv.net/en/
Login successful.
Unable to get User Id, please check your cookie.
Please follow the instruction in https://github.com/Nandaka/PixivUtil2/issues/814#issuecomment-711182644

PixivException.PixivException: PixivException(100 Unable to get User Id, please check your cookie., hasDumpPage=Y)

Cannot Login!

I logged out of Pixiv site and logged back in, copied the new cookie value over to config.ini, but I'm still getting the same error message in PixivUtil2. I also tried the method of changing my password and getting the cookie, but that didn't work either. I also updated my user-agent with information from my Firefox browser, but that didn't fix it either.

I still can't login in PixivUtil2. I tried using Chrome browser user-agent and cookie to login, but now I get a different error:

Trying to log in with saved cookie
Error at doLogin(): (<class 'mechanize._response.get_seek_wrapper_class.<locals>.httperror_seek_wrapper'>, <httperror_seek_wrapper (urllib.error.HTTPError instance) at 0x1e21b21bbe0 whose wrapped object = <HTTPError 403: 'Forbidden'>>, <traceback object at 0x000001E21B256940>)

mechanize._response.get_seek_wrapper_class.<locals>.httperror_seek_wrapper: HTTP Error 403: Forbidden

Cannot Login!

I put in the Chrome user-agent and the Chrome cookie, and the above is the resulting error. I'm able to login and use Pixiv website on both browsers completely fine, so I don't understand why my login information isn't working in PixivUtil2 anymore. Anyone have any idea what else I can do?

edit: I shortened the user-agent to just Mozilla/5.0 while using the chrome information. The result is the same error message from my first post.

tldr, my bodged solution:

i.e. change temp = re.findall(r"var dataLayer = .*user_id: \"(\d+)\"", parsed) in line 597 of PixivBrowserFactory.py to temp = re.findall(r"var dataLayer = .*user_id:'(\d+)'", parsed).

I received the same error message and I took a look in it.

In my case, dataLayer received from Pixiv was like this:

'use strict'; var dataLayer = [{login:'yes',gender:'<MYGENDER>',user_id:'<MYID>',lang:'ja',illustup_flg:'not_uploaded',premium:'no',default_service_is_touch:'yes'}];

Not sure this is my fault, I did tinker some config values while trying to solve issue by searching through issues here.
But both values in my Chrome browser and that PixivUtil received seems to be in this format.

I don't think this warrants deep debug dive, but maybe proper parsing of dataLayer array instead of regex parsing would be nice.
I am happy to do some work for you, but I currently don't know much about js parsing in python, so ask me if you want me to then I will start looking for options.

Always grateful for your work, Nandaka and all contributors!

You have to run from the source code. Not super easy in Windows especially for non-programmers, but it can be done.
Follow https://github.com/Nandaka/PixivUtil2/wiki/IDE-Enviroment-(Windows) and come back if you are stuck.
