使用angularJS发布数据到API

Question

我是Angular的新手，想知道如何发布数据。

我有角做了一个控制器：

myApp.factory('employeeServices', ['$http', function ($http) { 

    var factoryDefinitions = { 
    moveToBench: function (employeeId) { 
      var data = $.param({ 
       json: JSON.stringify({ 
        "entityId": employeeId, 
        "nextStateId": myApp.state.bench 
       }) 
      }); 
return $http.post(myApp.IndecommBaseUrl + '/Workflow',data).success(function (data) { 
       return data; 
      }); 
     } 
    } 

    return factoryDefinitions; 
    } 
]); 

//Controller 
myApp.controller('getEmployeesController', ['$scope', 'employeeServices', 'dataTable', function ($scope, employeeServices, dataTable) { 
    employeeServices.getEmployees().then(function (result) { 
    $scope.moveToBench = function (id) { 

      employeeServices.moveToBench(id); 
     } 

    }); 
}]); 

我在HTML按钮：

<button class="btn btn-success" ng-click="moveToBench(employee.employee.id)">Move To Bench</button> 

按下按钮，我可以看到，在值：

moveToBench: function (employeeId) { 
      var data = $.param({ 
       json: JSON.stringify({ 
        "entityId": employeeId, 
        "nextStateId": myApp.state.bench 
       }) 

是正确的。但是，尽管达到了API，其值为NULL ..

后端API控制器：

// POST api/values 
     [HttpPost] 
     public void Post(int entityId, int nextStateId) 
     { 
      JObject jsonObject = JObject.Parse(System.IO.File.ReadAllText("Config.Json")); 
      string jsonFile = jsonObject.GetValue("WorkfowJsonFileLocation").ToString(); 
      var nextState = _stateServices.Get(nextStateId); 
      var handler = new WorkflowHandler(nextState, jsonFile, _entityServices, 1, _stateServices, _subStateServices, _appServices); 
      handler.PerformAction(entityId); 
     } 

谁能帮我这个？

似乎在设置params之前调用return语句。请尝试在线版本：

moveToBench: function (employeeId) { 
    return $http.post(myApp.IndecommBaseUrl + '/Workflow', $.param({ 
       json: JSON.stringify({ 
         "entityId": employeeId, 
         "nextStateId": myApp.state.bench 
         }) 
       })) 
      .success(function (data) { 
       return data; 
      }); 
     }
