Django REST框架身份验证

Question

我想在 Django 中创建身份验证。我正在尝试按照this 做所有事情。 不幸的是，此时我有两个问题。首先，当我尝试添加from rest_framework.authtoken import views 时，我与from companies import views 发生冲突。我需要从 authtoken 到 url(r'^api-token-auth/', views.obtain_auth_token) 的视图。其次，当我使用/api-token-auth/ 我的问题是我只能登录超级用户，对于我数据库中的其他用户，我得到响应 - "Unable to log in with provided credentials."

Answer 1

使用 as 来消除冲突。

from companies import views as companies_views
from rest_framework.authtoken import views as rest_auth_views

并在网址中使用它url(r'^api-token-auth/', rest_auth_views.obtain_auth_token)

提供详细信息不足以调试导致身份验证的原因。您能否提供有关基于令牌的身份验证的更多代码。

更新：

与 OP 沟通后。他使用UserSerializer 创建了用户，并将密码保存为纯文本。而且身份验证不起作用。

class UserSerializer(serializers.ModelSerializer): 

    class Meta: 
        model = User 

        fields = '__all__'`

    def create(self, validated_data):
        user = User.objects.create_user(**validated_data)
        return user

Answer 2

您需要在您的settings.py 中包含TokenAuthentication 到您的DEFAULT_AUTHENTICATION_CLASSES。

来自文档，

要使用 TokenAuthentication 方案，您需要配置身份验证类以包含 TokenAuthentication。

所以像这样改变你的 settings.py，

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.BasicAuthentication',
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework.authentication.TokenAuthentication',
    )
}
