配置文件 config.php

<?php//配置文件header('Content-Type: text/html; charset=UTF-8');$qq_k=''; //QQ应用APP ID$qq_s=''; //QQ应用APP KEY$callback_url='http://yoururl/callback.php'; //授权回调网址$scope='get_user_info,add_share'; //权限列表，具体权限请查看官方的api文档

示例文件 demo.php

<?phpsession_start(); //此示例中要使用sessionrequire_once('config.php');require_once('qq.php');$qq_t=isset($_SESSION['qq_t'])?$_SESSION['qq_t']:'';//检查是否已登录if($qq_t!=''){    $qq=new qqPHP($qq_k, $qq_s, $qq_t);    $qq_oid=$qq->get_openid();    $openid=$qq_oid['openid']; //获取登录用户open id    //获取登录用户信息    $result=$qq->get_user_info($openid);    var_dump($result);    /**    //发布分享    $title='开源中国'; //分享页面标题    $url='http://www.oschina.net/'; //分享页面网址    $site=''; //QQ应用名称    $fromurl='';  //QQ应用网址    $result=$qq->add_share($openid, $title, $url, $site, $fromurl);    var_dump($result);    **/    /**    //其他功能请根据官方文档自行添加    //示例：根据openid获取用户信息    $result=$qq->api('user/get_user_info', array('openid'=>$openid), 'GET');    var_dump($result);    **/}else{    //生成登录链接    $qq=new qqPHP($qq_k, $qq_s);    $login_url=$qq->login_url($callback_url, $scope);    echo '<a href="',$login_url,'">点击进入授权页面</a>';}

回调文件 callback.php

<?php//授权回调页面，即配置文件中的$callback_urlsession_start(); //此示例中要使用sessionrequire_once('config.php');require_once('qq.php');if(isset($_GET['code']) && trim($_GET['code'])!=''){    $qq=new qqPHP($qq_k, $qq_s);    $result=$qq->access_token($callback_url, $_GET['code']);}if(isset($result['access_token']) && $result['access_token']!=''){    echo '授权完成，请记录<br/>access token：<input size="50" value="',$result['access_token'],'">';    //保存登录信息，此示例中使用session保存    $_SESSION['qq_t']=$result['access_token']; //access token}else{    echo '授权失败';}echo '<br/><a href="demo.php">返回</a>';
