我有一个验证码，当我收到200响应状态的成功消息然后它很好但是如果我得到401页面应该显示错误，因为我设置了一些错误状态但是这不会发生我得到了视图也刷新，结果是空白。请帮忙

app.controller('MyController', ['$scope', '$location', '$http','$rootScope','$route','$localStorage', function ($scope, $location, $http, $rootScope,$route, $localStorage) {
    $scope.username = "";
    $scope.password = "";
    $scope.ipsenData = {};
    $scope.username="";
    $scope.password="";
    $scope.invalidUser="";

    /*Functionalities of the Application*/
    $scope.login = function () {
        $http.post('/ipsen/login', {
            username: $scope.username,
            password: $scope.password
        }).
        success(function (data, status, headers, config) {
            if(status===200){
                console.log("Login Successful");
                $http.get('/ipsen/getrole?userName='+$scope.username)
                .success(function (data, status, headers, config) {
                    if(data.rows[0].RoleName==="Ipsen Manager"){
                        var data = data.rows[0];
                        /*Username and Role Storage*/
                         $localStorage.username=$scope.username;
                         $localStorage.FirstName=data.FirstName;
                         $localStorage.LastName=data.LastName;
                         $localStorage.OrganizationName=data.OrganizationName;
                         $localStorage.RoleName=data.RoleName;
                         $localStorage.Email=data.Email;


                         $location.path('/customers').replace();
                    }
                    else{
                         var data = data.rows[0];
                        /*Username and Role Storage*/
                         $localStorage.FirstName=data.FirstName;
                         $localStorage.LastName=data.LastName;
                         $localStorage.OrganizationName=data.OrganizationName;
                         $localStorage.RoleName=data.RoleName;
                         $localStorage.Email=data.Email;
                         $location.path('/furnacelist/'+$scope.username+"/"+"customer").replace();
                    }
                    /**/
                })
                .error(function (data, status, headers, config) {
                    console.log(data);
                });
            }
        }).
        error(function (data, status, headers, config) {
            if(status === 401){
                $scope.invalidUser="Please Enter Valid Username & Password";
            }
        });
    };
}]);

您可以设置如下所示的拦截器，这可能会有所帮助，以便在401上您的用户只会被卡在登录页面上。

function APIInterceptor($rootScope, $q) {
    var service = this;
    service.responseError = function(response) {
      console.log("in responseError", response); // just to see the error initially
      if (response.status === 401) {
        $rootScope.$broadcast('unauthorized');
        return $q.reject(response);
      }

      return response;
    };
  }

然后将拦截器放在处理路由的配置文件中。

   $httpProvider.interceptors.push('APIInterceptor');

使用rootScope.$on中的.run使用以下代码。

  $rootScope.$on('unauthorized', function() {
      // ... some code to handle tokens, cookies, whatever ... set to null
      $location.path('/login');
    });

我还遗漏了其他一些内容，但我认为你明白了。基本上，您希望在其中添加拦截器来处理您的请求和响应。

在角度中使用$ http.get时视图会消失？当401作为响应返回时，ng-view是否会关闭？
