问题描述
我正在开始使用 dj-rest-auth，并且我有一个应用程序，它只允许用户通过谷歌登录。但是，我希望用户只能使用特定的 Google Apps 电子邮件域访问我的服务。
我将 dj-rest-auth 与 django-allauth 结合使用。
这是我尝试过的：我创建了这样的 allauth 适配器：
class CustomAccountAdapter(DefaultAccountAdapter):
def is_open_for_signup(self,request):
return False # No email/password signups allowed
class CustomSocialAccountAdapter(DefaultSocialAccountAdapter):
def is_open_for_signup(self,request,socialaccount):
u = socialaccount.user
return u.email.split("@")[1] == "mydomain.com"
在我的设置中我有
ACCOUNT_ADAPTER = "users.adapters.CustomAccountAdapter"
SOCIALACCOUNT_ADAPTER = "users.adapters.CustomSocialAccountAdapter"
使用此解决方案，如果用户尝试使用有效的电子邮件登录，一切正常，而如果他们使用不允许的电子邮件域，我会在控制台中收到此错误：

[17/Mar/2021 18:49:42] "POST /dj-rest-auth/google HTTP/1.1" 500 246781
我想要做的是让我的 django 应用程序向用户（或类似用户）发送 403 响应，其中包含一条消息，例如“您只能使用 [at] 任何电子邮件地址访问此服务”。 我试图弄清楚 dj-rest-auth 视图在哪一点调用用户适配器以及如何处理失败并实现我所追求的目标。
感谢任何指导。
解决方法
当你返回 is_open_for_signup==False 时，django-allauth 在内部返回一个模板：
if not get_adapter(request).is_open_for_signup(request,sociallogin):
return render(
request,"account/signup_closed." + account_settings.TEMPLATE_EXTENSION,)
该模板扩展了模板 account/base.html（在 django-allauth 项目中），并且在此模板中您定义了有问题的 URL <li><a href="{% url 'account_login' %}">Sign In</a></li>
您可以覆盖您的 signup_closed.html 模板并解决此错误，但如果您需要返回 Json（由于 API），您应该使用您自己的 django-allauth 实现。
