My web app is successfully going through google's recommended flow to get credentials to query Google Drive API. This works fine. However, when I try to use the same credentials already obtained to get the user's email and name, I get an error.
Here I retrieve credentials and query Google Drive API. This works perfectly fine
def analyze():
credentials = getCredentials()
drive_service = googleapiclient.discovery.build('drive', 'v3', credentials=credentials)
theFiles = drive_service.files().list(pageSize=1000,q="trashed=false", fields="files(id,name,modifiedTime, size)").execute() #THIS WORKS
Right after that, I try to use the SAME CREDENTIALS to get user info, but now it doesn't work
oauth2_client = googleapiclient.discovery.build('oauth2','v2',credentials=credentials)
user_info= oauth2_client.userinfo().get().execute() #THIS FAILS
givenName = user_info['given_name']
Error: https://www.googleapis.com/oauth2/v2/userinfo?alt=json returned "Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.">
SOME OTHER IMPORTANT FUNCTIONS:
def getCredentials():
*Loads credentials from the session.*
sc = session['credentials']
credentials = google.oauth2.credentials.Credentials(token=sc.get('token'),
client_id=sc.get('client_id'),
refresh_token=sc.get('refresh_token'),
token_uri=sc.get('token_uri'),
client_secret=sc.get('client_secret'),
scopes=sc.get('scopes'))
the credentials are obtained in the callback page:
@app.route('/OAcallback')
def OAcallback():
flow =google_auth_oauthlib.flow.Flow.from_client_secrets_file('client_id.json', scopes=['https://www.googleapis.com/auth/drive https://www.googleapis.com/auth/userinfo.profile'])
flow.redirect_uri = return_uri
authorization_response = request.url
flow.fetch_token(authorization_response=authorization_response)
credentials = flow.credentials
* Store the credentials in the session.*
credentials_to_dict(credentials)
Please help me understand why my credentials are not working when trying to get user info. What should I change?
Thanks in advance!!!
You are only requesting the profile scope. To also request the email address add the scope email.
Change this part of your code from:
scopes=['https://www.googleapis.com/auth/drive https://www.googleapis.com/auth/userinfo.profile']
to:
scopes=['https://www.googleapis.com/auth/drive https://www.googleapis.com/auth/userinfo.profile' 'email']
