django rest身份验证社交连接到Vkontakte（vk）

请帮助我为提供商Vkontakte建立休息社交连接。 我正在使用django allauth库（）。 和django rest auth用于rest auth（）

我已经有了VKOAuth2Serializer，可以很好地登录和注册。 但是连接不起作用。 以下是URL：

观点：

序列化程序：

下面是注册/登录视图和工作正常的URL：

请帮我连接Vkontakte的REST。

项目在这里：

尝试连接VK时-出现错误：

现在需要VK API版本字段。您可以从github repo重写VKOAuth2Adapter类

---

由于VK需要自定义提供程序逻辑，您需要使用序列化程序，该序列化程序的逻辑在

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，新的序列化程序和连接视图将如下所示：

序列化程序：

from rest_auth.registration.serializers import SocialConnectMixin


class VKOAuth2ConnectSerializer(SocialConnectMixin, VKOAuth2Serializer):
    pass

视图：

---

您可以发布一个从连接视图中得到的错误吗？/rest auth/vk/connect/'response'请求方法：发布请求URL:Django版本：2.0.3异常类型：KeyError异常值：'response'异常位置：/code/allauth/socialaccount/providers/vk/views.py在完整登录中，第54行我已经检查过了。当我尝试连接VK时，它会创建新帐户，而不是将其连接到当前帐户…两个帐户是否使用相同的电子邮件？我使用不同的电子邮件。。。但是连接twitter和facebook也没问题（它也有不同的电子邮件）。只有VK创建新帐户，而不是连接。有没有可能使vk的工作方式与twitter和facebook相同？谢谢，我知道，我已经有了vk api版本字段。正如我所说，REST登录工作正常。我也需要休息才能正常工作。正常连接（而非REST）也适用于vk。现在需要让它工作休息…谢谢，我会检查它，稍后回来
