django rest-auth 社交连接到 Vkontakte (vk)

Question

请帮助我为提供商 Vkontakte 制作 REST 社交连接。 我正在使用 django-allauth 库 (https://github.com/pennersr/django-allauth)。 还有 django-rest-auth 用于 REST 身份验证 (https://github.com/Tivix/django-rest-auth)。

我已经有 VKOAuth2Serializer 可以正常登录并注册。 但是连接不起作用。 这是网址：

url(r'^rest-auth/vk/connect/$', views.VkConnect.as_view(), name='vk_connect'),
url(r'^rest-auth/vk/', views.VkLogin.as_view()),

查看次数：

from allauth.socialaccount.providers.oauth2.client import OAuth2Client
from allauth.socialaccount.providers.vk.views import VKOAuth2Adapter

class VkLogin(CustomSocialLoginView):
    adapter_class = VKOAuth2Adapter
    serializer_class = VKOAuth2Serializer
    client_class = OAuth2Client
    callback_url = 'http://localhost:3000'

class VkConnect(SocialConnectView): 
    adapter_class = VKOAuth2Adapter
    #May be here should be something else?

序列化器：

from allauth.socialaccount.helpers import complete_social_login
from rest_auth.registration.serializers import SocialLoginSerializer
from django.utils.translation import ugettext_lazy as _
from requests.exceptions import HTTPError

    email = serializers.CharField(required=False, allow_blank=True)
    user_id = serializers.CharField(required=False, allow_blank=True)

    def validate(self, attrs):
        view = self.context.get('view')
        request = self._get_request()

        if not view:
            raise serializers.ValidationError(_("View is not defined, pass it as a context variable"))

        adapter_class = getattr(view, 'adapter_class', None)
        if not adapter_class:
            raise serializers.ValidationError(_("Define adapter_class in view"))

        adapter = adapter_class(request)
        app = adapter.get_provider().get_app(request)

        # Case 1: We received the access_token
        if attrs.get('access_token'):
            if not attrs.get('user_id') or not attrs.get('email'):
                raise serializers.ValidationError(_("Incorrect input. email and user_id is required with access_token."))

            access_data = {

                'email': attrs.get('email'),
            }

        # Case 2: We received the authorization code
        elif attrs.get('code'):
            self.callback_url = getattr(view, 'callback_url', None)
            self.client_class = getattr(view, 'client_class', None)

            if not self.callback_url:

            if not self.client_class:
                raise serializers.ValidationError(_("Define client_class in view"))

            code = attrs.get('code')

            provider = adapter.get_provider()
            scope = provider.get_scope(request)

                request,

                adapter.access_token_method,
                adapter.access_token_url,
                self.callback_url,
                scope
            )
            access_data = client.get_access_token(code)
            if attrs.get('email'):
                access_data['email'] = attrs.get('email')
            if not access_data.get('email'):
                raise serializers.ValidationError(_("Incorrect input. Social account must have email, otherwise send it in email field."))
        else:
            raise serializers.ValidationError(_("Incorrect input. access_token or code is required."))

        social_token = adapter.parse_token({'access_token': access_data['access_token']})
        social_token.app = app

        try:
            login = self.get_social_login(adapter, app, social_token, access_data)
            complete_social_login(request, login)
        except HTTPError:
            raise serializers.ValidationError(_('Incorrect value'))

        if not login.is_existing:
            login.lookup()
            login.save(request, connect=True)
        attrs['user'] = login.account.user

        return attrs

Answer 1

由于 VK 需要自定义提供程序逻辑，您需要使用序列化程序，其逻辑在 VKOAuth2Serializer 中定义，但社交登录状态进程设置为 connect。您可以通过使用SocialConnectMixin 创建VKOAuth2Serializer 的子类来实现它。

因此，您的新序列化程序和连接视图将如下所示：

序列化器：

from rest_auth.registration.serializers import SocialConnectMixin


class VKOAuth2ConnectSerializer(SocialConnectMixin, VKOAuth2Serializer):
    pass

查看：

class VkConnect(SocialConnectView): 
    adapter_class = VKOAuth2Adapter
    serializer_class = VKOAuth2ConnectSerializer

Answer 2

现在需要 VK API 版本字段。您可以从 github repo 重写 VKOAuth2Adapter 类 https://github.com/pennersr/django-allauth/blob/master/allauth/socialaccount/providers/vk/views.py
