Question

的http://127.0.0.1:8000/rest-auth/login/中执行我的逻辑

当我登录时，它就像下面一样，网址由django-rest-auth提供。

登录时如何编写自己的逻辑？

Answer 1

该页面包含有关您可以覆盖哪些api端点的信息 http://django-rest-auth.readthedocs.io/en/latest/configuration.html

登录时可以使用：＆＃39; LOGIN_SERIALIZER＆＃39;：＆＃39; path.to.custom.LoginSerializer＆＃39;，为了实现自定义注册逻辑和序列化，我建议您阅读http://www.django-rest-framework.org/的文档。

<强> 1。将其设置在您的settings.py中，如文档中所示

REST_AUTH_SERIALIZERS = {
    'LOGIN_SERIALIZER': 'path.to.custom.LoginSerializer',
    ...
}

<强> 2。创建Serailizer类

这是默认的Login Serializer类（复制并粘贴到上面使用的url并根据需要进行编辑）

注意：您也可以使用型号Serializer

class LoginSerializer(serializers.Serializer):
    username = serializers.CharField(required=False, allow_blank=True)
    email = serializers.EmailField(required=False, allow_blank=True)
    password = serializers.CharField(style={'input_type': 'password'})

    def _validate_email(self, email, password):
        user = None

        if email and password:
            user = authenticate(email=email, password=password)
        else:
            msg = _('Must include "email" and "password".')
            raise exceptions.ValidationError(msg)

        return user

    def _validate_username(self, username, password):
        user = None

        if username and password:
            user = authenticate(username=username, password=password)
        else:
            msg = _('Must include "username" and "password".')
            raise exceptions.ValidationError(msg)

        return user

    def _validate_username_email(self, username, email, password):
        user = None

        if email and password:
            user = authenticate(email=email, password=password)
        elif username and password:
            user = authenticate(username=username, password=password)
        else:
            msg = _('Must include either "username" or "email" and "password".')
            raise exceptions.ValidationError(msg)

        return user

    def validate(self, attrs):
        username = attrs.get('username')
        email = attrs.get('email')
        password = attrs.get('password')

        user = None

        if 'allauth' in settings.INSTALLED_APPS:
            from allauth.account import app_settings

            # Authentication through email
            if app_settings.AUTHENTICATION_METHOD == app_settings.AuthenticationMethod.EMAIL:
                user = self._validate_email(email, password)

            # Authentication through username
            if app_settings.AUTHENTICATION_METHOD == app_settings.AuthenticationMethod.USERNAME:
                user = self._validate_username(username, password)

            # Authentication through either username or email
            else:
                user = self._validate_username_email(username, email, password)

        else:
            # Authentication without using allauth
            if email:
                try:
                    username = UserModel.objects.get(email__iexact=email).get_username()
                except UserModel.DoesNotExist:
                    pass

            if username:
                user = self._validate_username_email(username, '', password)

        # Did we get back an active user?
        if user:
            if not user.is_active:
                msg = _('User account is disabled.')
                raise exceptions.ValidationError(msg)
        else:
            msg = _('Unable to log in with provided credentials.')
            raise exceptions.ValidationError(msg)

        # If required, is the email verified?
        if 'rest_auth.registration' in settings.INSTALLED_APPS:
            from allauth.account import app_settings
            if app_settings.EMAIL_VERIFICATION == app_settings.EmailVerificationMethod.MANDATORY:
                email_address = user.emailaddress_set.get(email=user.email)
                if not email_address.verified:
                    raise serializers.ValidationError(_('E-mail is not verified.'))

        attrs['user'] = user
        return attrs

如何在`django-rest-auth`的`http：//127.0.0.1：8000 / rest-auth / login /`中执行我的逻辑？
