angular-JS模仿Form表单提交

$http({
     url: "http://localhost:10086/yuanxin/Conference/ImportExcelDataForBusRoute",method: 'Post'    
     },data: { BusRoute: file,ConferenceID: "1" },transformRequest: function (data,headersGetter) {//进行格式转换，非常关键
             var formData = new FormData();将model转为表单格式
             angular.forEach(data,function (value,key) {
                   formData.append(key,value);
             });
             var headers = headersGetter();
             delete headers['Content-Type'];
             return formData;
     }
}).success( (data) {
     $scope.isSubming = false;
     $scope.BusRouteColl = data.dataList;
     $scope.pageIndex = 1;
     $scope.pageCount = data.pageCount;
     alert(data.property.mp);
}).error( (ex,state) {
     alert(ex);
     console.log(state + ":" + ex.exceptionMessage);
     console.log(ex.stackTrace);
     $scope.isSubming = ;
});
