GoogleCredential¶

GoogleCredential() is the base class of all the other classes. It provides an access to the Google API credentials -- no matter if you have ever generated a token before.

GoogleCredential.credential¶

credential(credential_path="", credential_scopes=None, token_prefix="", token_suffix="")

Initialize the Google credential.

If there is 'token.pickle' file in the credential_path and the token is valid, then it would load the pickle file.

Note: Whenever you modify the credential scope, you have to delete the 'token.pickle' file and generate a new token.

Otherwise, it would use 'credentials.json' file in the credential_path, prompt an authetication web page, request the user to confirm the credential_scopes, and download the token in the same folder.

You can customize the name of 'token.pickle' with token_prefix and token_suffix in case there are tokens with different scopes.

For example, use 'GoogleDrive_token_all.pickle' to indicate this token has all the scopes in Google Drive.
