请帮助我为提供商 Vkontakte 进行 REST 社交连接。 我正在使用 django-allauth 库（https://github.com/pennersr/django-allauth）。 用于REST身份验证的 django-rest-auth （https://github.com/Tivix/django-rest-auth）。
我已经有VKOAuth2Serializer可以正常登录并注册。 但连接不起作用。 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：
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?
串行：

答案 0 :(得分：2)
由于VK需要自定义提供程序逻辑，因此您需要使用VKOAuth2Serializer中定义的逻辑的序列化程序，但社交登录状态进程设置为connect。您可以通过使用VKOAuth2Serializer创建SocialConnectMixin的子类来实现它。
因此，您的新序列化程序和连接视图将采用以下方式：
串行：
from rest_auth.registration.serializers import SocialConnectMixin
class VKOAuth2ConnectSerializer(SocialConnectMixin, VKOAuth2Serializer):
pass
查看：
class VkConnect(SocialConnectView):
adapter_class = VKOAuth2Adapter
serializer_class = VKOAuth2ConnectSerializer
答案 1 :(得分：0)
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
