前言：

PHP实现QQ快速登录，罗列了三种方法

方法一：面向过程，回调地址和首次触发登录写到了一个方法页面【因为有了if做判断】，

方法二，三：面向对象

1.先调用登录方法，向腾讯发送请求， 2.腾讯携带本网站唯一对应参数OPENID,ACCESSTOKEN，返回到对应回调页面， 3.回调页面接受到腾讯的参数后，通过这个两个参数，再发出对应的请求，如查询用户的数据。 4.腾讯做出对应的操作，如返回这个用户的数据给你

即使你没看懂，也没关系，按照我下面的流程来，保证你可以实现。

前期准备：

使用人家腾讯的功能，总得和人家打招呼吧！

QQ互联首页：http://connect.qq.com/

进入网址后，按如下操作来：

一.进入官网

二.申请创建【网站】应用

三.按要求填写资料

注意网站地址：填写你要设置快速登录的网址，eg:http://www.test.com;  

回调地址:填写你发送QQ快速登陆后，腾讯得给你信息，这个信息往此页面接受。eg:http://www.test.com/accept_info.php

【详细的申请填写，请见官方提示，这里不做赘述】

四.申请成功后，完善信息

最终要求，获得APP_ID ，APP_KEY

五.代码部分：

在你对应的PHP文件内写入，如下 方法一，面向过程法 使用方法：配置$app_id，$app_secret，$my_url后，其他原封复制即可，$user_data为返回的登录信息 代码：

//应用的APPID 
 $app_id = "你的APPID"; 
 //应用的APPKEY 
 $app_secret = "你的APPKEY"; 
 //【成功授权】后的回调地址，即此地址在腾讯的信息中有储存 
 $my_url = "你的回调网址"; 
 
 //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，成功授权后回调时会原样带回 
 $_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); 
 if (strpos($response, "callback") !== false)//如果登录用户临时改变主意取消了，返回true!==false,否则执行step3 
 { 
 $lpos = strpos($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; 
 } 
 //echo("Hello " . $user->openid); 
 //echo("Hello " . $params['access_token']); 
 
 //Step4：使用<span style="font-family: Arial, Helvetica, sans-serif;">openid,</span><span style="font-family: Arial, Helvetica, sans-serif;">access_token来获取所接受的用户信息。</span> 
 $user_data_url = "https://graph.qq.com/user/get_user_info?access_token={$params['access_token']}&oauth_consumer_key={$app_id}&openid={$user->openid}&format=json"; 
 
 $user_data = file_get_contents($user_data_url);//此为获取到的user信息 
 } 
 else 
 { 
 echo("The state does not match. You may be a victim of CSRF."); 
 } 

方法二，面向对象 使用类QQ_LoginAction.class 使用方法： 1.在QQ_LoginAction.class中正确配置 APPID，APPKEY CALLBACK(回调网址) 2.在调用方法中，代码：

$qq_login = new \Component\QQ_LoginAction(); //引入此类文件即可 
$qq_login->qq_login(); //调用登录方法，向腾讯发出快速登录请求 

3.在回调页面中，代码：

$qc = new \Component\QQ_LoginAction(); 
$acs = $qc->qq_callback();<span style="white-space:pre"> //access_token 
$oid=$qc->get_openid();<span style="white-space:pre"> //openid 
$user_data = $qc->get_user_info();<span style="white-space:pre"> //get_user_info()为获得该用户的信息，其他操作方法见API文档 

4.$user_data即为返回的用户数据。 5.QQ_LoginAction.class.php 文件代码：【用的ThinkPHP3.2】

方法三，面向对象 使用腾讯给的SDK 使用方法:腾讯SDK，API写的很详细，不做赘述 地址：http://wiki.connect.qq.com/%E7%BD%91%E7%AB%99%E6%8E%A5%E5%85%A5%E6%A6%82%E8%BF%B0

这样就实现了QQ快捷登录，其实很简单的，大家可以试一试。 还有什么不清楚的，可以看看官方介绍，更详细，

Tips:如何在本地测试QQ快速登录 方法：修改HOST配置文件 1. 打开C:\Windows\System32\drivers\etc\host 2. 添加127.0.0.1    www.test.com 然后操作就可以了。
