AngularJS與后端php的數據交互方法

<?php
$data = file_get_contents("php://input");
echo $data;

var ws = angular.module("app",[function ($httpProvider) {
 $httpProvider.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded;charset=utf-8";
 $httpProvider.defaults.headers.put['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';
 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;
 };
 $httpProvider.defaults.transformRequest = [function (data) {
 return angular.isObject(data) && String(data) !== "[object File]" ? param(data) : data;
 }];
}]);
