我试图在我的自定义身份验证中覆盖 is_authenticated 。我有一些简单的（开始）像这样：

class MyAuthentication(BasicAuthentication):
    def __init__(self, *args, **kwargs):
        super(MyAuthentication, self).__init__(*args, **kwargs)

    def is_authenticated(self, request, **kwargs):
        return True

然后在我的 ModelResource 我有

class LoginUserResource(ModelResource):

    class Meta:
        resource_name = 'login'
        queryset = User.objects.all()
        excludes = ['id', 'email', 'password', 'is_staff', 'is_superuser']
        list_allowed_methods = ['post']

        authentication = MyAuthentication()
        authorization = DjangoAuthorization()

我不断收到 500 错误"error_message": "column username is not unique"。我在数据库中只有一个用户名，它是我要验证的用户。

关于为什么返回此错误的任何想法？我将如何允许 api 客户端登录？

谢谢您的帮助。

您的方法将尝试使用您正在验证的用户名创建一个新用户。正如您所注意到的，这将在 DB 层冒泡，这样的用户已经存在。

您想要的是创建一个UserResource，在其上添加一个方法，用户可以发布并使用传入用户名/密码的数据登录。

from django.contrib.auth.models import User
from django.contrib.auth import authenticate, login, logout
from tastypie.http import HttpUnauthorized, HttpForbidden
from django.conf.urls import url
from tastypie.utils import trailing_slash

class UserResource(ModelResource):
    class Meta:
        queryset = User.objects.all()
        fields = ['first_name', 'last_name', 'email']
        allowed_methods = ['get', 'post']
        resource_name = 'user'

    def override_urls(self):
        return [
            url(r"^(?P<resource_name>%s)/login%s$" %
                (self._meta.resource_name, trailing_slash()),
                self.wrap_view('login'), name="api_login"),
            url(r'^(?P<resource_name>%s)/logout%s$' %
                (self._meta.resource_name, trailing_slash()),
                self.wrap_view('logout'), name='api_logout'),
        ]

    def login(self, request, **kwargs):
        self.method_check(request, allowed=['post'])

        data = self.deserialize(request, request.raw_post_data, format=request.META.get('CONTENT_TYPE', 'application/json'))

        username = data.get('username', '')
        password = data.get('password', '')

        user = authenticate(username=username, password=password)
        if user:
            if user.is_active:
                login(request, user)
                return self.create_response(request, {
                    'success': True
                })
            else:
                return self.create_response(request, {
                    'success': False,
                    'reason': 'disabled',
                    }, HttpForbidden )
        else:
            return self.create_response(request, {
                'success': False,
                'reason': 'incorrect',
                }, HttpUnauthorized )

    def logout(self, request, **kwargs):
        self.method_check(request, allowed=['get'])
        if request.user and request.user.is_authenticated():
            logout(request)
            return self.create_response(request, { 'success': True })
        else:
            return self.create_response(request, { 'success': False }, HttpUnauthorized)

现在您可以发送 POST 到http://hostname/api/user/loginwith data { 'username' : 'me', 'password' : 'l33t' }。

此更新消除了 GET 方法的安全问题。适用于 Django 1.5.4。

class UserResource(ModelResource):

    class Meta:
        queryset = User.objects.all()
        resource_name = 'user'
        allowed_methods = ['post']


    def prepend_urls(self):
        return [
            url(r"^user/login/$", self.wrap_view('login'), name="api_login"),
            url(r"^user/logout/$", self.wrap_view('logout'), name='api_logout'),
        ]

    def login(self, request, **kwargs):
        self.method_check(request, allowed=['post'])

        data = self.deserialize(request, request.raw_post_data, format=request.META.get('CONTENT_TYPE', 'application/json'))

        username = data.get('username', '')
        password = data.get('password', '')

        user = authenticate(username=username, password=password)
        if user:
            if user.is_active:
                login(request, user)
                return self.create_response(request, {
                    'success': True
                })
            else:
                return self.create_response(request, {
                    'success': False,
                    'reason': 'disabled',
                }, HttpForbidden )
        else:
            return self.create_response(request, {
                'success': False,
                'reason': 'incorrect',
                }, HttpUnauthorized )

    def logout(self, request, **kwargs):
        self.method_check(request, allowed=['post'])
        if request.user and request.user.is_authenticated():
            logout(request)
            return self.create_response(request, { 'success': True })
        else:
            return self.create_response(request, { 'success': False }, HttpUnauthorized)
