Question

当我发送正确的凭据时，我收到HTTP_200_OK响应，一切都按预期工作。但是，当我发送不正确或不完整的登录凭据时，我不会得到任何回复。这是我的代码：

Angular（authService.js登录功能）：

$http({
    method : 'POST',
    url : API_LOCATION + 'login',
    data : $.param(credentials),
    headers : {'Content-Type': 'application/x-www-form-urlencoded'}
}).then(function(response){
    console.log(response);
    if(response.status == 200){
        authService.currentUser = response.data;
        $location.path('/')
    }
    else {
        $rootScope.alert = response.data.message;
    }
});

Django休息框架 - 登录视图：

class LoginView(views.APIView):

    serializer_class = UsersSerializer
    permission_classes = (AllowAny, )
    allowed_methods = ('GET', 'POST', 'OPTIONS', 'HEAD')

    def get(self, *args, **kwargs):
        serializer = self.serializer_class(self.request.user, context={'request' : self.request})
        return Response(serializer.data)

    def post(self, *args, **kwargs):

        username = self.request.data.get('username', None)
        password = self.request.data.get('password', None)

        if username and password:
            user = authenticate(username=username, password=password)

        else:
            print '400'
            return Response({"message": "Both fields are required"}, status=views.status.HTTP_400_BAD_REQUEST)

        if not user:
            print '401'
            return Response({"message": "Incorrect login"}, status=views.status.HTTP_401_UNAUTHORIZED)

        login(self.request, user)

        serializer = self.serializer_class(user, context={'request' : self.request})

        return Response(serializer.data, status = views.status.HTTP_200_OK)

＆＃39; 400＆＃39;和＆＃39; 401＆＃39;分别打印在控制台中，但我没有得到任何角度响应。帮助

修改

谢谢pgreen2，得到了它。错误回调函数中收到错误响应：

$http({
    method : 'POST',
    url : API_LOCATION + 'login',
    data : $.param(credentials),
    headers : {'Content-Type': 'application/x-www-form-urlencoded'}
}).then(function successCallback(response) {
    if(response.status == 200){
        authService.currentUser = response.data;
        $location.path('/')
    }
}, function errorCallback(response) {
    console.log(response)
});

401和400是错误代码，因此您需要在角度中添加.catch（）到您的承诺。错误发生了，但你没有代码处理它。

更新

UserManager<ApplicationUser> userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
var user = userManager.FindByName(currentUser.LoginName); // currentUser is the currently logged in user
IdentityResult result1 = userManager.RemovePassword(user.Id);
IdentityResult result2 = userManager.AddPassword(user.Id, txtPassword1.Text);

Angular没有收到来自django rest framework
