$http post传值的问题

 var app = angular.module("myApp", [], function ($httpProvider) {
               
            $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';
            /**
            * The workhorse; converts an object to x-www-form-urlencoded serialization.
            * @param {Object} obj
            * @return {String}
            */
            var param = function (obj) {
                var query = '', name, value, fullSubName, subName, subValue, innerObj, i;

                for (name in obj) {
                    value = obj[name];

                    if (value instanceof Array) {
                        for (i = 0; i < value.length; ++i) {
                            subValue = value[i];
                            fullSubName = name + '[' + i + ']';
                            innerObj = {};
                            innerObj[fullSubName] = subValue;
                            query += param(innerObj) + '&';
                        }
                    }
                    else if (value instanceof Object) {
                        for (subName in value) {
                            subValue = value[subName];
                            fullSubName = name + '[' + subName + ']';
                            innerObj = {};
                            innerObj[fullSubName] = subValue;
                            query += param(innerObj) + '&';
                        }
                    }
                    else if (value !== undefined && value !== null)
                        query += encodeURIComponent(name) + '=' + encodeURIComponent(value) + '&';
                }

                return query.length ? query.substr(0, query.length - 1) : query;
            };

            // Override $http service's default transformRequest
            $httpProvider.defaults.transformRequest = [function (data) {
                return angular.isObject(data) && String(data) !== '[object File]' ? param(data) : data;
            } ];

        });

  app.controller("addController", ["$scope", "$http", function ($scope, $http) {

            $scope.save = function () {
                if ($scope.myForm.$valid) {
                    var data = { "name": $scope.txtname, "address": $scope.txtaddress, "phone": $scope.txtphone, "zipcode": $scope.txtzipcode, "isdefault": $scope.cbxisdefault };
                    $http.post("AddUserAddress", data).success(function (result) {
                        alert(result);
                    });
                }
            }
        } ]);

只有配置了$http的默认文档类型才能再后台用Request来获取提交的参数
