Ionic 发送Http post PHP 获取不到数据

1.app.js 配置请求设置

  $httpProvider.defaults.headers.post={
         'Content-Type':'application/x-www-form-urlencoded'}
       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;
       }];

2.controller.js

      $scope.openGet=function(){
         $http.get("http://192.168.108:8000/ionic.php?uname=su").success(
           function(response){
             console.log("status:"+response.status);
             alert(response.status);
           }
         ).error(function(){
           //错误消息
         });
       }
       $scope.openPost=function(){

         $http({
           method: "POST",
           url: "http://192.168.108:8000/ionic.php",
           data: {"id":'101'},
         }).success(
           function(response) {
             alert(response.id);
           }
         ).error(function(er) {
           alert(er);
         });
       }

3.html

<button  ng-click="openGet()">GET</button>
<button  ng-click="openPost()">POST</button>

4.服务端代码

 <?php

 $callback = isset($_GET['callback']) ? trim($_GET['callback']) : ''; //jsonp回调参数，必需
 //采用jsonp 解决跨域问题 方式处理
 if($callback!=''){
     $callback = $_GET['callback'];
     $date = array('status'=>'1','msg'=>'OK');
     echo $callback.'('.json_encode($data).')';
 }
 else{

 //通过header解决跨域问题
 header('Content-Type: application/json');
 header("Access-Control-Request-Method: *");
 header('Access-Control-Allow-Headers:x-requested-with,content-type');
 header("Access-Control-Allow-Origin: *");
 header('Access-Control-Max-Age: 60');

 $uname = isset($_GET['uname']) ? trim($_GET['uname']) : ''; 

 //echo  json_decode($_POST);

 $id=isset($_POST['id'])?$_POST['id']: '';
     if($uname!=''){
        $date = array('uname'=>$uname);
         $date["msg"]="get OK";
         $date["status"]="1";
         echo json_encode($date);
      }
     if($id!=''){
             $date = array('id'=>$id);
             $date["msg"]="Post OK";
             $date["status"]="1";
             echo json_encode($date);
     }
     //echo json_decode(file_get_contents('php://input'),true);
 }

 ?>
