在AngularJS中的401未经授权的错误处理

我在AngularJS中非常新手,现在花3天时间找到处理401状态的方法.我试过拦截器,使用$http,使用$资源…但没有任何工作.我的应用程序在同一台服务器上调用 JSONP调用.当错误发生时,它被捕获在错误回调函数中.但状态始终为0,响应未定义.

首先,我试过这个拦截器

app.config(['$httpProvider',function($httpProvider) {
$httpProvider.responseInterceptors.push(['$q',function($q) {
    return function(promise) {
        return promise.then(function(response) {
            console.log('success in interceptor');
            return response; 
        },function(response) {
            console.log('error in interceptor');
            console.log(response);
            if (response.status === 401) {
                response.data = { 
                    status: false,description: 'Authentication required!'
                };
                return response;
            }
            return $q.reject(response);
        });
    }
}]);
}]);

第二,也在使用$资源的控制器中尝试过

$scope.fetchData = function(fromDate,toDate){
        Cancel.get({from: fromDate,to: toDate,perPage: 99999},function(data){                            
                      $scope.cancels  = $scope.filteredCancels = data.data;
                      $scope.search();
                    },function(response) {
                      $scope.errorMessage = '<h4>Error : '+response.status+'</h4>';
                      window.location = "/";
                    });              
      };

第三,尝试使用$http而不是$资源

$scope.fetchData = function(fromDate,toDate){
     $http.jsonp('http://host:8900/api/cancellations?callback=JSON_CALLBACK')
         .success(function(data,status,headers,config) {
             console.log(status);
          })
         .error(function(data,config) {
             console.log(status);              
          };

这是JSONP调用的头信息

我找不到办法处理未经授权的状态401,我捆绑了所有的东西.如果我能得到一个提示或善意的建议,将是非常感激的.

我最近需要做的很相似,这里是我的拦截器

app.factory("HttpErrorInterceptorModule",["$q","$rootScope","$location",function($q,$rootScope,$location) {
        var success = function(response) {
            // pass through
            return response;
        },error = function(response) {
                if(response.status === 401) {
                    // dostuff
                }

                return $q.reject(response);
            };

        return function(httpPromise) {
            return httpPromise.then(success,error);
        };
    }
]).config(["$httpProvider",function($httpProvider) {
        $httpProvider.responseInterceptors.push("HttpErrorInterceptorModule");
    }
]);
