我能够使用 Django (1.6.4)、allauth (0.16.1) 和 Python (2.7) 成功通过 Google 和 Facebook 登录，并预期重定向到 settings.LOGIN_REDIRECT_URL，以防没有检索到电子邮件 ID 的现有用户来自提供商。但是，当已经存在与从提供商（fb 或 goolge）检索到的电子邮件 ID 相同的用户时，它总是重定向到 /accounts/social/signup/#= 注册页面，询问：
您将使用您的 Facebook/Google 帐户登录 example.com。作为 最后一步，请填写以下表格： 电子邮件是自动填写的。
我用
SOCIALACCOUNT_AUTO_SIGNUP = TrueFalse我有以下设置.py：
ACCOUNT_AUTHENTICATION_METHOD = "email" # Defaults to username_email
ACCOUNT_USERNAME_REQUIRED = False # Defaults to True
ACCOUNT_EMAIL_REQUIRED = True # Defaults to False
SOCIALACCOUNT_QUERY_EMAIL = ACCOUNT_EMAIL_REQUIRED
SOCIALACCOUNT_AUTO_SIGNUP = True
SOCIALACCOUNT_EMAIL_REQUIRED = False
ACCOUNT_ADAPTER = "myproject.adapter.MyLoginAccountAdapter"
LOGIN_URL = "/"
LOGIN_REDIRECT_URL = "/users/{id}/mytags"
如何停止此重定向到注册，并让提供商登录重定向到 LOGIN_REDIRECT_URL（特别是具有相同电子邮件 ID 的现有用户）？
注意：这个我已经尝试过了
更新：
@receiver(pre_social_login)和
raise ImmediateHttpResponse（看看我的答案）和有用的链接解决了这个问题：this 和 thisone
问题正在解决：我只是希望能够使用相同的电子邮件 ID 使用 facebook 和 google 互换登录，并在成功登录后始终重定向到 LOGIN_REDIRECT_URL，但 django-allauth 不允许我这样做。相反，它向我展示了一个我不想要的注册页面。
解决方案：：使用 @receiver(pre_social_login)
调用函数
link_to_local_user()，该函数首先登录，然后引发 ImmediateHttpResponse，后者又重定向到 LOGIN_REDIRECT_URL

我使用了@amulllb 答案，但它有点过时了。

class EmailNotFoundException(Exception):
"""Exception raised when email is not found in social login data."""
def __init__(self, message="Email or mail not found in social login data"):
self.message = message
super().__init__(self.message)
这与@amulllb 的答案有何不同？is_authenticated()
而我更改为 .is_authenticated 因为 Django 停止使用 is_authenticated 作为方法一段时间了。
email_address = sociallogin.account.extra_data['email']
，而我检查了
email和
mail。
mail是 Microsoft Graph 返回的内容。我还添加了一个例外，以防提供者既不使用
email也不使用
mail。
