angular-JS模仿Form表單提交

直接上示例代碼，有不懂的歡迎留言：

$http({
     url: "http://localhost:10086/yuanxin/Conference/ImportExcelDataForBusRoute",
     method: 'Post',
     headers: {
            'Content-Type': 'multipart/form-data'    
     },
     data: { BusRoute: file, ConferenceID: "1" },
     transformRequest: function (data, headersGetter) {//進行格式轉換，非常關鍵
             var formData = new FormData();//將model轉為表單格式
             angular.forEach(data, function (value, key) {
                   formData.append(key, value);
             });
             var headers = headersGetter();
             delete headers['Content-Type'];
             return formData;
     }
}).success(function (data) {
     $scope.isSubming = false;
     $scope.BusRouteColl = data.dataList;
     $scope.pageIndex = 1;
     $scope.pageCount = data.pageCount;
     //alert(data.property.mp);
}).error(function (ex, state) {
     alert(ex);
     console.log(state + ":" + ex.exceptionMessage);
     console.log(ex.stackTrace);
     $scope.isSubming = false;
});
