jQuery中用ajax访问php接口文件

js代码

function ajax_request(){

  var result;
  var articleId = new Object();
  articleId=getArticleId();

    $.ajax({
    url: "/topicPage/getComment.php",//请求php文件的路径
    data:{id:articleId},//请求中要传送的参数,会自动拼接成一个路径，在php中用get方式获取参数值
    dataType: "json",//请求数据类型JSON
    type: "get",//请求发方式get
    async:false,
    success: function(json) {
      result = json.data;//j将请求到的数据返回给result
    }
    });
    return result;

　　php代码

<?php
    $url="http://api.xxx.com/api/v1/tr/xxxx/1138121/comments?strategy=hot";
     $headers=array(
         'common-info:{"device_platform": "web","language":"tr","auth_type":xxx,"user_id":'.xxxx.', "version_code": xxxx}'
     );
    $curl=curl_init();
    curl_setopt($curl,CURLOPT_URL,$url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_NOBODY, FALSE);
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
    $result=curl_exec($curl);
    curl_close($curl);
    echo $result;
?>
