如何在asp.net mvc5中将获取的值从后端传递到前端？

Question

我有一个存储过程，它等同于并获得房间的占用率。我想使用 JSon 从后端获取数据，并在前端代码中显示存储过程的输出数据。 但输出数据仅限于 业务层。如何使用 Json 从我的控制器中调用它？

这是我的代码

在我的控制器

中

 public JsonResult GetoccupancyRate()
    {
        string _connectionString = rAppSetting.ConnectionString;

        try
        {
            IList<Hotel> _currentOccupancyRateList = rHotelFacade.GetOccupancyRate(HotelIDCookie, DateTime.Now, _connectionString);
            IList<Hotel> _yesterdayOccupancyRateList = rHotelFacade.GetOccupancyRate(HotelIDCookie, DateTime.Now.AddDays(-1), _connectionString);


            return Json(new
            {
                success = true,
                message = "Success",
                yesterdayOccupancyRate = _yesterdayOccupancyRateList,
                currentOccupancyRate = _currentOccupancyRateList
            },JsonRequestBehavior.AllowGet);
        }
        catch (Exception ex)
        {
            return Json(new
            {
                success = false,
                message = ex.Message,
                currentOccupancyRate = "",
                yesterdayOccuoancyRate = ""
            }, JsonRequestBehavior.AllowGet);
        }
    }

的Javascript

myapp.factory("occupancyRateService", ['$http', function ($http) {
this.LoadOccupancyRate = function () {
    return $http.get("/Dashboard/GetOccupancyRate", {});
};
return this;}]);

myapp.controller('MainController', ['$scope', 'dashboardService', 'occupancyRateService', function ($scope, dashboardService, occupancyRateService) {
    $scope.myChart = {
        type: 'google.charts.Bar',
        options: {},
        data: {}
    };
$scope.loadOccupancyRateDetails = function () {
        occupancyRateService.LoadOccupancyRate().success(function (result) {
            if (result.success)
            {
                var currentOccupancyRateData = result.currentOccupancyRate;
                var yesterdayOccupancyRateData = result.yesterdayOccupancyRate;

                console.log(result.currentOccupancyRate);
                console.log(result.yesterdayOccupancyRate);
