Question

获得授权URL后，无法将其交换为令牌。每次致电(authorization_response=self.request)时，都会被AttributeError: 'WSGIRequest' object has no attribute 'lower'

击中

如何将身份验证URL交换为令牌？下面的代码：

urlpatterns = [
    path('ytauth/<int:pk>/', YtAuthView.as_view(), name='yt_auth'),
    path('oauth2callback/', Oauth2CallbackView.as_view(), name='oauth2callback')

]

class YtAuthView(UserPassesTestMixin, UpdateView):
    model = Profile
    form_class = YtAuthForm
    template_name = 'yt_auth_update.html'

    def form_valid(self, form):
        CLIENT_SECRETS_FILE = "collab-web-client.json"
        SCOPES = ['https://www.googleapis.com/auth/youtube.force-ssl']
        API_SERVICE_NAME = 'youtube'
        API_VERSION = 'v3'

        flow = google_auth_oauthlib.flow.Flow.from_client_secrets_file(
            client_secrets_file=CLIENT_SECRETS_FILE,
            scopes=SCOPES)

        flow.redirect_uri = 'https://127.0.0.1:8000/profiles/oauth2callback/'

        auth_flow = youtube_base()
        auth_url = auth_flow.get_authenticated_service()

        return redirect(auth_url)

class youtube_base:

    def get_authenticated_service(self):

        flow = google_auth_oauthlib.flow.Flow.from_client_secrets_file(
            client_secrets_file=CLIENT_SECRETS_FILE,
            scopes=SCOPES)

        flow.redirect_uri = 'http://127.0.0.1:8000/profiles/oauth2callback/'

        authorization_url, state = flow.authorization_url(access_type='offline')

        return authorization_url

这是我的授权URL的样子。

https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=clientIdhere.apps.googleusercontent.com&redirect_uri=http%3A%2F%2F127.0.0.1%3A8000%2Fprofiles%2Foauth2callback%2F&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fyoutube.force-ssl&state=t14XG3dAK0zQX8DOBGB0nO3Mk7nYes&access_type=offline

class Oauth2CallbackView(View):

    def get(self, request, *args, **kwargs):
        flow = google_auth_oauthlib.flow.Flow.from_client_secrets_file(
            CLIENT_SECRETS_FILE, scopes=SCOPES)
        flow.redirect_uri = 'https://127.0.0.1:8000/profiles/oauth2callback/'


        flow.fetch_token(authorization_response=self.request)

        return redirect('http://127.0.0.1:8000/profiles/')

Answer 1

您的声明：

flow.fetch_token（authorization_response = self.request）

不正确。使用authorization_response = self.request.url代替authorization_response = self.request。

Answer 2

self.request.get是

<QueryDict: 
{'state': ['STATE'], 
'code': ['CODE'], 
'scope': ['SCOPE']}>

解决方案是flow.fetch_token(code=self.request.GET.get('code'))
