Python Oauth2 - faça o login com o Google
Eu tenho procurado por 2 dias para uma resposta, mas nada apareceu.
Estou tentando integrar o Oauth2 para fazer login com o Google no Django. O código que eu lance uma exceção - "O token é inválido".
Isto acontece:
<code>resp, content = client.request(access_token_url, "POST") if resp['status'] != '200': print content raise Exception("Invalid response from Google."+content) </code>
em google_authenticate ()
Por favor me ajude.
Meu código:
<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('/') </code>
