本文实例讲述了PHP调用QQ互联接口实现QQ登录网站功能。分享给大家供大家参考,具体如下:

调用QQ登录接口,首先要到QQ互联完善开发者认证信息,并通过审核,然后创建一个网站应用,获得APP ID和APP Key,通过审核后即可调用基本接口get_user_info(获得用户信息),实现QQ登录网站功能。

废话不多,上示例代码(QQ登录李维山博客):


<?php
 header("Content-Type: text/html;charset=utf-8");
 //应用APP ID
 $app_id = "101486017";
 //应用APP Key
 $app_secret = "13a1811780f29d7a5b64e598c38a4494";
 //应用填写的网站回调域
 $my_url = "http://www.msllws.top/qqlogin";
 //Step1:获取Authorization Code
 session_start();
 $code = $_REQUEST["code"];//存放Authorization Code
 if(empty($code)) {
 //state参数用于防止CSRF攻击,成功授权后回调时原样带回
 $_SESSION['state'] = md5(uniqid(rand(), TRUE));
 //拼接URL
 $dialog_url = "https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id=".$app_id."&redirect_uri=".urlencode($my_url)."&state=".$_SESSION['state'];
 echo("<script> top.location.href='".$dialog_url."'</script>");
 }
 //Step2:通过Authorization Code获取Access Token
 if($_REQUEST['state'] == $_SESSION['state'] || 1) {
 //拼接URL
 $token_url = "https://graph.qq.com/oauth2.0/token?grant_type=authorization_code&"."client_id=".$app_id."&redirect_uri=".urlencode($my_url)."&client_secret=".$app_secret."&code=".$code;
 $response = file_get_contents($token_url);
 //如果用户临时改变主意取消登录,返回true!==false,否则执行step3 
 if (strpos($response, "callback") !== false) {
 $lpos = strpos($response, "(");
 $rpos = strrpos($response, ")");
 $response = substr($response, $lpos + 1, $rpos - $lpos -1);
 $msg = json_decode($response);
 if (isset($msg->error)) {
 echo "<h3>error:</h3>".$msg->error;
 echo "<h3>msg :</h3>".$msg->error_description;
 exit;
 }
 }
 //Step3:使用Access Token来获取用户的OpenID
 $params = array();
 parse_str($response, $params);//把传回来的数据参数变量化
 $graph_url = "https://graph.qq.com/oauth2.0/me?access_token=".$params['access_token'];
 $str = file_get_contents($graph_url);
 if (strpos($str, "callback") !== false) {
 $lpos = strpos($str, "(");
 $rpos = strrpos($str, ")");
 $str = substr($str, $lpos + 1, $rpos - $lpos -1);
 }
 $user = json_decode($str);//存放返回的数据 client_id ,openid
 if (isset($user->error)) {
 echo "<h3>error:</h3>".$user->error;
 echo "<h3>msg :</h3>".$user->error_description;
 exit;
 }
 //Step4:使用openid和access_token获取用户信息
 $user_data_url = "https://graph.qq.com/user/get_user_info?access_token={$params['access_token']}&oauth_consumer_key={$app_id}&openid={$user->openid}&format=json";
 $user_data = file_get_contents($user_data_url);//获取到的用户信息
 //以下为授权成功后的自定义操作
 if($user_data){
 // ......
 echo("<script> top.location.href='http://www.msllws.top'</script>");
 }else{
 echo '未知错误';
 }
 }else{
 echo("The state does not match. You may be a victim of CSRF.");
 }
