当我使用此模板和查看时，我可以使用任何电子邮件地址和密码登录。但我想使用我的电子邮件地址和密码登录（我的意思是只使用一个电子邮件地址登录）。我有可能吗？

Answer 1

您可以使用自定义身份验证编写严格的条件。像：

user = your_custom_authenticate(username=username, password=psd)

当方法your_custom_authenticate

中的用户名是您的电子邮件时，您可以返回用户对象

有一些方法可以做你想做的事。 view全部由你自己控制。如果context是您的电子邮件，则只需将render然后email设置为另一条路径即可。当然，如果您的下一页需要session件事，那么您应该在session中保存一些用户信息，这完全取决于您。

Answer 2

您可以使用检查当前username是否为用户名的函数来包装默认def custom_auth(username=None, password=None): user = None if username == 'my_personal@email.com': # only this email is allowed user = authenticate(username=email, password=psd) return user def login_submit(request): context = {} email = request.POST.get('email','') psd = request.POST.get('password', '') user = custom_auth(username=email, password=psd) if user is not None: ... else: ... return render (request,'login.html',context)，如下所示：
