我有一个自定义用户模型并创建了一个自定义身份验证后端。我正在使用django rest frameworkdjango rest framework JWT进行令牌身份验证。

用户型号:

class User(AbstractBaseUser, PermissionsMixin):
    email = models.EmailField(
        unique=True,
        max_length=254,
    )
    first_name = models.CharField(max_length=15)
    last_name = models.CharField(max_length=15)
    mobile = models.IntegerField(unique=True)
    date_joined = models.DateTimeField(default=timezone.now)
    is_active = models.BooleanField(default=True)
    is_admin = models.BooleanField(default=False)
    objects = UserManager()
    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['first_name', 'last_name', 'mobile']

身份验证后端:

class EmailOrMobileAuthBackend(object):
    def authenticate(self, username=None, password=None):
        try:
            user = get_user_model().objects.get(email=username)
            if user.check_password(password):
                return user
        except User.DoesNotExist:
            if username.isdigit():
                try:
                    user = get_user_model().objects.get(mobile=username)
                    if user.check_password(password):
                        return user
                except User.DoesNotExist:
                    return None
            else:
                return None

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

并在settings.py中添加:

AUTHENTICATION_BACKENDS = ('accounts.email_mobile_auth_backend.EmailOrMobileAuthBackend',)

在登录 django 管理站点时,电子邮件和手机号码都可以很好地验证用户身份。但是,当我尝试使用django rest framework JWT为用户获取令牌时,出现错误:

curl -X POST -d "email=admin@gmail.com&password=123123" http://localhost/api-token-auth/

"non_field_errors": [
    "Unable to log in with provided credentials."
  ]

我还在 Rest 框架的默认身份验证中添加了自定义身份验证后端类,但它仍然无法正常工作:

REST_FRAMEWORK = {
    ...
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'accounts.email_mobile_auth_backend.EmailOrMobileAuthBackend',
        'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
    ),
}

我错过了什么?为什么它在登录到 django 管理站点时工作,但在使用 django rest framework jwt 获取令牌时出错?

更新

我按照建议制作了另一个身份验证后端并将其添加到 中DEFAULT_AUTHENTICATION_CLASSES,但即使这样也不起作用。

class DrfAuthBackend(BaseAuthentication):
    def authenticate(self, username=None, password=None):
        try:
            user = get_user_model().objects.get(email=username)
            if user.check_password(password):
                return user, None
        except User.DoesNotExist:
            if username.isdigit():
                try:
                    user = get_user_model().objects.get(mobile=username)
                    if user.check_password(password):
                        return user, None
                except User.DoesNotExist:
                    return None
            else:
                return None

设置:

REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.IsAdminUser',
    ),
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'accounts.email_mobile_auth_backend.EmailOrMobileAuthBackend',
        'accounts.email_mobile_auth_backend.DrfAuthBackend',
        'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
    ),
}

更新

args将auth 类中的从usernameto更改为email似乎可以获取,auth_token但再次无法登录到管理站点。

class EmailOrMobileAuthBackend(object):
    def authenticate(self, email=None, password=None):
        try:
            user = get_user_model().objects.get(email=email)
            if user.check_password(password):
                return user
        except User.DoesNotExist:
            if email.isdigit():
                try:
                    user = get_user_model().objects.get(mobile=email)
                    if user.check_password(password):
                        return user
                except User.DoesNotExist:
                    return None
            else:
                return None

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

您应该查看DRF 文档以了解自定义身份验证后端。

我认为您的自定义身份验证后端正在破坏它,您可以通过从 DRF 设置中删除您的来解决它:

REST_FRAMEWORK = {
    ...
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
    ),
}

或者通过修复你的,这与 Django 自定义身份验证基本不同,因为你应该扩展authentication.BaseAuthentication它并返回一个元组。

from rest_framework import authentication


class DrfAuthBackend(authentication.BaseAuthentication):
    def authenticate(self, email=None, password=None):
        try:
            user = get_user_model().objects.get(email=email)
            if user.check_password(password):
                return user, None
        except User.DoesNotExist:
            if email.isdigit():
                try:
                    user = get_user_model().objects.get(mobile=email)
                    if user.check_password(password):
                        return user, None
                except User.DoesNotExist:
                    return None
            else:
                return None

然后在 DRF 设置中使用它:

REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.IsAdminUser',
    ),
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'accounts.email_mobile_auth_backend.DrfAuthBackend',
        'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
    ),
}

对于 Django 登录:

class EmailOrMobileAuthBackend(object):
    def authenticate(self, username=None, password=None):
        try:
            user = get_user_model().objects.get(email=username)
            if user.check_password(password):
                return user
        except User.DoesNotExist:
            if username.isdigit():
                try:
                    user = get_user_model().objects.get(mobile=username)
                    if user.check_password(password):
                        return user
                except User.DoesNotExist:
                    return None
            else:
                return None

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

然后进行设置:

AUTHENTICATION_BACKENDS = ('accounts.email_mobile_auth_backend.EmailOrMobileAuthBackend',)

在您的 settings.py 文件中,添加以下内容:

AUTH_USER_MODEL = 'accounts.email_mobile_auth_backend.EmailOrMobileAuthBackend'
