Question

配置为ACCOUNT_AUTHENTICATION_METHOD = 'username_email'的Django AllAuth中是否有任何方法可以从输入"USERNAME OR EMAIL"发送文本并自动进行身份验证？我的意思不是前端逻辑，只是AllAuth身份验证。因此，它将获得带有字段"username_email" : "myusername", "password" : "password"或"username_email" : "myemail@gmail.com", "password" : "password"的JSON，并且它将自动检查是否有昵称或电子邮件为myusername的用户并且密码为password。在第二种情况下，它还将检查昵称或电子邮件为myemail@gmail.com的用户是否存在，其密码为password。如果是这样，将对用户进行身份验证。有什么想法吗？

您需要自定义身份验证后端doc

类似这样的东西：

class MyAuthenticationBackend:

    def authenticate(self, email_username=None, password=None):
        if "@" in email_username:
            try:
                user = User.objects.get(email=email_username)
            except User.DoesNotExist:
                return None
        else:
            try:
                user = User.objects.get(username=email_username)
            except User.DoesNotExist:
                return None
        if getattr(user, 'is_active', False) and user.check_password(password):
            return user
        return None

    def get_user(self, user_id):
        try:
            return User.objects.get(pk=user_id)
        except User.DoesNotExist:
            return None

然后在表单视图中：

from django.contrib.auth import authenticate
from django.contrib.auth import login
from django.shortcuts import redirect

class LoginView(FormView):
    template_name = 'my-auth/login.html'
    form_class = LoginForm

    def form_valid(self, form):
        data = form.cleaned_data
        user = authenticate(email_username=data['email_username'], password=data['password'])
        if user is None:
            form.add_error(None, _('Wrong email/username'))
            return self.form_invalid(form)
        login(self.request, user)
        return redirect('somewhere')

如何在一个字段中使用电子邮件或用户名使用Django AllAuth对用户进行身份验证？
