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);
}

?>
