Question

我正在尝试自定义social_auth.backends.contrib.vk.VKOAuth2Backend 但是当我启用自定义后端时会出现此错误

WrongBackend at / login / vk-oauth /

身份验证服务不正确＆＃34; vk-oauth＆＃34;

来自设置的authentication_backends

AUTHENTICATION_BACKENDS = (
    'social_auth.backends.facebook.FacebookBackend',
    'social_auth.backends.contrib.vk.VKOAuth2Backend',
    'social_auth.backends.google.GoogleOAuth2Backend',
    'social_auth.backends.contrib.odnoklassniki.OdnoklassnikiBackend',
    # '_auth.backends.CustomVKOAuth2Backend',
    'profiles.backends.ModelBackend',
)

如果我取消注释我的CustomVKOAuth2Backend会出现问题，但是使用VKOAuth2Backend时，一切都会按预期运行。

from social_auth.backends.contrib.vk import VKOAuth2Backend

class CustomVKOAuth2Backend(VKOAuth2Backend):
    """Custom VKOAuth2 authentication backend"""

    def get_user_details(self, response):
        """Return user details from VK account"""
        lname = response.get('last_name', '')
        fname = response.get('first_name', '')
        name = fname + lname
        email = response.get('email', '')

        return {
            'username': response.get('screen_name'),
            'email': email,
            'first_name': fname,
            'last_name': lname,
            'name': name
        }

它们几乎是一致的，所以我无法理解问题出在哪里这是有效的后端

class VKOAuth2Backend(OAuthBackend):
    """VKOAuth2 authentication backend"""
    name = 'vk-oauth'

    EXTRA_DATA = [
        ('id', 'id'),
        ('expires', 'expires')
    ]

    def get_user_id(self, details, response):
        """OAuth providers return an unique user id in response"""
        return response['user_id']

    def get_user_details(self, response):
        """Return user details from VK account"""
        return {
            'username': response.get('screen_name'),
            'email': '',
            'first_name': response.get('first_name'),
            'last_name': response.get('last_name')
        }

如何在django社交认证中自定义身份验证后端？
