Python Oauth2 - connexion avec Google

J'ai été la recherche de 2 jours pour une réponse, mais rien n'est venu.

Je suis en train de faire intégrer Oauth2 pour la connexion avec Google sur Django. Le code que j'ai déclenche une exception - "Le jeton n'est pas valide".

Ce qui se passe:

resp, content = client.request(access_token_url, "POST")
    if resp['status'] != '200':
        print content
        raise Exception("Invalid response from Google."+content)

dans google_authenticate()

S'il vous plaît, m'aider.

Mon code:

    def google_login(request):
scope = "https://www.googleapis.com/auth/userinfo.profile"
request_token_url = "https://www.google.com/accounts/OAuthGetRequestToken?scope=%s" % scope
authorize_url = 'https://www.google.com/accounts/OAuthAuthorizeToken'
authenticate_url = "https://accounts.google.com/o/oauth2/auth"
response_type = "code"
redirect_uri = "http://127.0.0.1:8000/login/google/auth"
scope = "https://www.googleapis.com/auth/userinfo.profile"
oauth_key = settings.GOOGLE_KEY
oauth_secret = settings.GOOGLE_SECRET
consumer = oauth.Consumer(oauth_key, oauth_secret)
client = oauth.Client(consumer)
# Step 1: Get a request token. This is a temporary token that is used for 
# having the user authorize an access token and to sign the request to obtain 
# said access token.
resp, content = client.request(request_token_url, "POST")
request_token = dict(urlparse.parse_qsl(content))
if resp['status'] != '200':
raise Exception("Invalid response from Google.")
# Step 2. Store the request token in a session for later use.
request.session['request_token'] = dict(cgi.parse_qsl(content))
# Step 3. Redirect the user to the authentication URL.
url = "%s?oauth_token=%s&client_id=%s&response_type=%s&redirect_uri=%s&scope=%s" % (authenticate_url,
request.session['request_token']['oauth_token'],
oauth_key,response_type,redirect_uri,scope)
return HttpResponseRedirect(url)
def google_authenticate(request):
access_token_url = 'https://www.google.com/accounts/OAuthGetAccessToken'
oauth_key = settings.GOOGLE_KEY
oauth_secret = settings.GOOGLE_SECRET
consumer = oauth.Consumer(oauth_key, oauth_secret)
# Step 1. Use the request token in the session to build a new client.
token = oauth.Token(request.session['request_token']['oauth_token'],
request.session['request_token']['oauth_token_secret'])
if 'oauth_verifier' in request.GET:
token.set_verifier(request.GET['oauth_verifier'])
client = oauth.Client(consumer, token)
# Step 2. Request the authorized access token from Google.
resp, content = client.request(access_token_url, "POST")
if resp['status'] != '200':
print content
raise Exception("Invalid response from Google."+content)
access_token = dict(cgi.parse_qsl(content))
# Step 3. Lookup the user or create them if they don't exist.
try:
user = User.objects.get(username=access_token['screen_name'])
except User.DoesNotExist:
# When creating the user I just use their [email protected]
# for their email and the oauth_token_secret for their password.
# These two things will likely never be used. Alternatively, you 
# can prompt them for their email here. Either way, the password 
# should never be used.
user = User.objects.create_user(access_token['screen_name'],
'%[email protected]' % access_token['screen_name'],
access_token['oauth_token_secret'])
# Save our permanent token and secret for later.
profile = Profile()
profile.user = user
profile.oauth_token = access_token['oauth_token']
profile.oauth_secret = access_token['oauth_token_secret']
profile.save()
# Authenticate the user and log them in using Django's pre-built 
# functions for these things.
user = authenticate(username=access_token['screen_name'],
password=access_token['oauth_token_secret'])
login(request, user)
return HttpResponseRedirect('/')
