Social login with VK about django-rest-auth

[gorros]

Thanks for reply.

I use following view:'

class VKLogin(SocialLogin):
    adapter_class = VKOAuth2Adapter

and receive following error

TypeError at /api/auth/vk/

string indices must be integers

which is result of following line in SocialLoginSerializer

 login = self.adapter.complete_login(request, app, token,
                                                response=access_token)

since complete_login in VK0Auth2Adapter is defined a little bit deferent that in Facebook0Auth2Adapter:

def complete_login(self, request, app, token, **kwargs):
        uid = kwargs['response']['user_id']
        resp = requests.get(self.profile_url,
                            params={'access_token': token.token,
                                    'fields': ','.join(USER_FIELDS),
                                    'user_ids': uid})
        resp.raise_for_status()
        extra_data = resp.json()['response'][0]
        return self.get_provider().sociallogin_from_response(request,
                                                             extra_data)

Mainly you a need also to pass user_id (kwargs['response']['user_id']) to obtain relevant response according http://vk.com/dev/users.get. And as I understand from VK API docs on this step access_token is not required.

The problem is actual. Please reopen issue.

I have the same problem too:
File ... in complete_login
37. uid = kwargs['response']['user_id']

Exception Type: TypeError at /api/vk/
Exception Value: string indices must be integers

What to do?

Sure, you can create your own SocialLoginSerializer and define your own view class, like:

from rest_auth.views import Login
class CustomLogin(Login):
    serializer_class = CustomSocialLoginSerializer
    adapter_class = VKOAuth2Adapter

Could you paste error traceback which you get when using VK adapter?

[mateusz-sikora]

So the only solution for you at this moment is to define you own social login serializer basing on SocialLoginSerializer and override validate method. There is no way to make it simpler, unfortunately.

You can also fork this project, make a patch and create a pull request to apply it to DRA code.

[gorros]

That's exactly what I was planing to do.

By the way, I am glad you fixed UserDetailsSerializer import in rest_auth/registration/views.py in v0.3.3 (e9fee3a).

Hi gorros, sorry I write it here, did you solve vk authorization issue? Can you help me with that?

@sburavtsov This was a while ago, but according to my code this should solve the problem.

class CustomVKOAuth2Adapter(VKOAuth2Adapter):

    def complete_login(self, request, app, token, **kwargs):
        uid = kwargs['response']['user_id']
        resp = requests.get(self.profile_url,
                            params={'fields': ','.join(USER_FIELDS),
                                    'user_ids': uid})
        resp.raise_for_status()
        extra_data = resp.json()['response'][0]
        return self.get_provider().sociallogin_from_response(request,
                                                             extra_data)

[sburavtsov]

Than you! I will try it.

I had the same problem so I had to find the solvation. The point is here:

  File "/home/kamirt/nissaenv/lib/python3.4/site-packages/rest_auth/registration/serializers.py", line 247, in validate
    login = self.get_social_login(adapter, app, social_token, access_token)
  File "/home/kamirt/nissaenv/lib/python3.4/site-packages/rest_auth/registration/serializers.py", line 180, in get_social_login
    social_login = adapter.complete_login(request, app, token, response=response)

This "response" parameter in case VK must be like this: {user_id:*******, access_token: *******, expire_time: *******}. But this function passes already parsed response (only access_code).

So what is the final solution?
Here is the whole code in urls.py:

from allauth.socialaccount.providers.vk.views import VKOAuth2Adapter

class CustomVKOAuth2Adapter(VKOAuth2Adapter):

    def complete_login(self, request, app, token, **kwargs):
        uid = kwargs['response']['user_id']
        resp = requests.get(self.profile_url,
                            params={'fields': ','.join(USER_FIELDS),
                                    'user_ids': uid})
        resp.raise_for_status()
        extra_data = resp.json()['response'][0]
        return self.get_provider().sociallogin_from_response(request,
                                                             extra_data)

in urlpatterns:

url(r'^rest-auth/vk/$', CustomVKOAuth2Adapter, name='vk_login'),

And I get error in browser what open http://127.0.0.1:8000/rest-auth/vk/:
AttributeError at /rest-auth/vk/ 'CustomVKOAuth2Adapter' object has no attribute 'status_code'

How to fix it?
