Question

您好我正在尝试获取http请求的状态并有条件地设置变量。我做了一个suball来检查user1是否跟随user2。我的代码看起来像这样。（为了简洁起见，我删除了foreach函数，该函数需要遍历我之前获得请求的用户列表，这是我必须推送的原因）

$scope.users = [];
  var getUser = function(id) {
        UserService.GetUserById(id, $localStorage.CurrentUser.auth_token)
        .success(function (data) {

         data = angular.fromJson(data);

//data model ==> {id: 0, username: "foo"}

//check if 404 or 200 ==> UserService.GetUserFollowers($stateParams.id, data.id)
//if 200 data.is_following = 1; if 404 data.is_following = 0

         $scope.users.push(data);  

//data model after pushed ==> {id: 0, username: "foo", is_following: 1}

         console.log(angular.toJson($scope.users));

        }).error(function(error, status) {
            alert(status);
            console.log(error);         
        });

    };

试过这个没有用的

$scope.users = [];
  var getUser = function(id) {
        UserService.GetUserById(id, $localStorage.CurrentUser.auth_token)
        .success(function (data) {

         $scope.data = angular.fromJson(data);

         UserService.GetUserFollowers($stateParams.id, $scope.data.id, -1, -1)
            .success(function(data, status) {                      
              $scope.status = status;
            }).error(function(data, status) {               
              $scope.status = status;
            });

       if ($scope.status === 200) {
          $scope.data.is_following = true;
       }else{
          $scope.data.is_following = false;
       }

        $scope.users.push($scope.data);

         console.log(angular.toJson($scope.users));

        }).error(function(error, status) {
            alert(status);
            console.log(error);         
        });

    };

这是我的服务：

  this.GetUserFollowers = function (my_id, to_id, begin, end) {
            return $http.get($rootScope.endPoint + '/user/' + my_id + '/followers/' + to_id + '/' + begin + '/' + end + '/');    
        };

！注意 - 如果to_id不是-1，则忽略begin和End

self.udp = nil;返回状态代码作为第二个参数。

$http

但是，如果状态是错误状态，例如404，则将调用$http.get(url) .success(function(data, status) { alert(status); // HTTP status code of the response }) .error(function(data, status) { alert('Error with status code: ' + status); });块。

if语句检查获取请求AngularJS的http状态
