Google OAuth error Required parameter is missing: grant_type

I'm trying this code:

import requests
url_token = 'https://accounts.google.com/o/oauth2/token'
params = {
    'code': request.values.get('code', '', type=str),
    'client_id': app.config['SOCIAL_GOOGLE']['consumer_key'],
    'client_secret': app.config['SOCIAL_GOOGLE']['consumer_secret'],
    'redirect_uri': urllib.quote_plus("https://example.com/google/code"),
    'grant_type': 'authorization_code'
}
out = requests.post(url_token, params=params)

using Python-Request in Flask. But I get error response:

ERROR - out={
   "error" : "invalid_request",
   "error_description" : "Required parameter is missing: grant_type"
}

It is standard POST request. Any hint why Google doesn't see grant_type parameter? Or is it misleading error message?

params is for adding query parameters to the URL in GET requests, data is for passing data to POST requests so you should pass the form POST parameters as:

out = requests.post(url_token, data=params)

see the docs at: http://docs.python-requests.org/en/latest/user/quickstart/#more-complicated-post-requests
