AngularJS $ http.post（...）。success不是文件上传方法的函数

Question

我试图通过angularjs web应用程序将新记录插入数据库，但问题是当我点击提交按钮时我在控制台窗口中出现以下错误。我正在尝试从angularjs应用程序发布wcf服务的数据。

 **TypeError: $http.post(...).success is not a function
        at Object.fac.UploadFile (Controllers.js:139)
        at Scope.$scope.SaveFile (Controllers.js:80)
        at fn (eval at compile (angular.js:15642), <anonymous>:4:144)
        at callback (angular.js:27463)

        at defaultHandlerWrapper (angular.js:3785)
        at HTMLFormElement.eventHandler (angular.js:3773)**

这是我的controller.js代码。

app.controller("AngularJs_WCFController", function ($scope, $timeout, $rootScope, $window, AngularJs_WCFService, FileUploadService) {
    $scope.date = new Date();
    //  To set and get the Item Details values 
    var firstbool = true;
    $scope.Imagename = "";
    $scope.Item_ID = "0";
    $scope.Item_Name = "";
    $scope.Description = "";
    $scope.Item_Price = "0";
    $scope.txtAddedBy = "";
    // This is publich method which will be called initially and load all the item Details.  
    GetItemDetails();
    //To Get All Records    
    function GetItemDetails() {
        var promiseGet = AngularJs_WCFService.GetItemDetails();
        promiseGet.then(function (pl) {
            $scope.getItemDetailsDisp = pl.data
        },
            function (errorPl) {
            });
    }

                var promisePost = AngularJs_WCFService.post(ItmDetails);
                promisePost.then(function (pl) {
                    alert(p1.data.Item_Name);

    });

从工厂中删除deferred Anti-pattern：

app.factory('FileUploadService', function ($http, $q) {
    var fac = {};
    fac.UploadFile = function (file) {
        var formData = new FormData();
        formData.append("file", file);
        ̶v̶a̶r̶ ̶d̶e̶f̶e̶r̶ ̶=̶ ̶$̶q̶.̶d̶e̶f̶e̶r̶(̶)̶;̶
        var promise = $http.post("/shanuShopping/UploadFile", formData,
            {
                withCredentials: true,
                headers: { 'Content-Type': undefined },
                transformRequest: angular.identity
            })
            .then(function(response) {
                return response.data;
            })
            .catch(function(error) {
                console.log("File Upload Failed!");
                return $q.reject(error);
            });
            //.success(function (d) {
            //    defer.resolve(d);
            //})
            //.error(function () {
            //    defer.reject("File Upload Failed!");
            //});
        return  ̶d̶e̶f̶e̶r̶.̶p̶r̶o̶m̶i̶s̶e̶;̶  promise;
    }
    return fac;
});
