尝试从Google Drive Api v3获取文件列表时出现编码错误

Question

I am trying to learn how to program a web app that queries Google Drive Api. My web is in python-Flask. I've gone through most details successfully but I'm stuck here:

@app.route('/analyze')
def analyze():
    if 'credentials' not in session:
        return redirect('authorize')
    credentials = google.oauth2.credentials.Credentials(session['credentials'])

drive_service = googleapiclient.discovery.build('drive', 'v3', credentials=credentials)
    files = drive_service.files().list().execute()

The credentials are loaded from the session (the user goes through the authorization flow in a different page / script). On this script, we recover the session and make a call to the Google Api:

But the call drive.files().list().execute() fails

The error is in the API's response and is as follows:

ValueError: {'client_id': 'heregoesclientid', 'client_secret': 'thisisclientsecret', 'refresh_token': 'xxxxxxxxxxxxxxxxxx', 'scopes': [' https://www.googleapis.com/auth/drive '], 'token': 'xxxxxxxxxxxxxxxxxxxxxxxx', 'token_uri': ' https://oauth2.googleapis.com/token '} could not be converted to unicode

Why can't the response be converted to Unicode? Is this a bug in Google API? Is there anything I could do to solve this?

Answer 1

If you're using the google-auth package, you need to pass the values into Credentials individually, instead of a dict: See here .

Your code may then look like:

    sc = session['credentials']
    credentials = google.oauth2.credentials.Credentials(
        token=sc.get('token'),
        client_id=sc.get('client_id'),
        ...etc

    )

Hope this helps, or let me know if you're not using google-auth , as this will be irrelevant.
