问题
I'm using the default code provided from google here, and I don't quite understand why its not working. The code outputs the prompt Please visit this URL to authorize this application: [google login URL]. When attempting to log in with the account designated as owner of the script under the google developers console I get a Error 403: access_denied error with the message The developer hasn’t given you access to this app. It’s currently being tested and it hasn’t been verified by Google. If you think you should have access, contact the developer [the email I just tried to log in with].

creds = pickle.load(token)

回答1:
The error message you are getting is related to the fact that your application has not been verified yet.
As mentioned in that link all applications that access google APIs using sensitive scopes need to go though googles verification process. Normal you are given a grace period of 100 users accessing your application before your application will be locked down and you wont be able to authorize anymore users until you verify your application it sounds like you may have hit that point.
Your only options would be to go though the verification process or to create a whole new project on Google developer console and use that client id instead as the one you are using is currently locked for additional users.

EDIT: I know there is an answer already, but this is in a step format for those (like myself) who need it extra clear
To fix this issue for me was this simple:
- Go to https://console.developers.google.com/
- On the top left beside the words "Google APIs" click the project dropdown on the right
- Ensure that your correct project is selected
- Click "OAuth consent screen" on the left side of the screen (below "Credentials")
- If you have not created a consent screen, do that first
- Under "Test users" there is a button called "+ ADD USERS"
- Type the email of the account you will be testing with, press enter, then click save.
- It should work now!
It seems like they updated this recently because last year I did not have to do this.
