php无法获取angularjs post数据

php $_POST 无法获取angluarjs post参数数据

/** * 公共路由 */var app_main = angular.module("main",["ngRoute"]);//配置路由app_main.config(function($routeProvider,$locationProvider,$httpProvider){$httpProvider.defaults.transformRequest=function(obj){    var str=[];    for(var p in obj){       str.push(encodeURIComponent(p)+"="+encodeURIComponent(obj[p]));    }    return str.join("&");};$httpProvider.defaults.headers.post={    'Content-Type':'application/x-www-form-urlencoded'};});app_main.controller("initController",function($rootScope,$scope,$route,$http,$location,$timeout){});

angularjs config加上以上代码就解决了
