本帖内容较多，大部分都是源码，要修改的地方只有一个，其他只要复制过去，就可以完美运行。本帖主要针对CI框架，不用下载SDK，按我下面的步骤，建文件，复制代码就可以了。10分钟不要，接口就可完成。
第一步：申请APP ID，APP KEY，申请地址：http://connect.opensns.qq.com/验证通过后：会得到APP ID,APP KEY。这是你用个文件把这些信息保持下来，免得用的时候有要上网去查，记录在本地记事本里，方便，用的时候打开就可以。如下：APP ID：*******APP KEY：******回调地址：http://test.com 第二步：如果你的系统没有安装curl，请先安装curl。怎么知道本地系统是否安装了curl呢，方法如下：1.在web服务器目录（ Ubuntu下的通常为 /var/www )新建crul.PHP文件2.编辑文件，键入下面一行代码： <?php phpinfo(); ?>3.保存文件4.打开浏览器，浏览该网页。（例如：http://localhost/curl.php)5.搜索"curl",如果没搜到就证明没安装curl。下面是安装方法：
打开终端，输入下面的命令：sudo apt-get install curl libcurl3 libcurl3-dev php5-curl再重启apache：sudo /etc/init.d/apache2 restart这样curl就安装好了，打开你刚才的那个页面，搜一下curl,就可以看到了curl了，这表示已经安装成功，很简单吧。如果还是没有，编辑你的php.ini文件,我的phpini.php文件在/etc/php5/apache2/php.ini,估计你的也差不多是在这个位置，去找找看，找到后，打开这个文件，在最后加上一行：
extension=curl.so保存文件后重启Apache服务器，再打开页面，就会出现curl了。
第三步：代码
注：腾讯提供了SDK，可以在官网下载：下载地址：http://wiki.connect.qq.com/sdk%E4%B8%8B%E8%BD%BD，如果不是CI框架，估计下载下来就可以用了，CI框架调用规则不同，所以要做修改，如果是CI框架下开发QQ登录接口，就不用下载SDK了，用我下面的代码，下面正式上代码，完整的代码。代码步骤：
1.打开application/config/constants.php文件写入如下代码：/*qq登陆*/define('GET_AUTH_CODE_URL', "https://graph.qq.com/oauth2.0/authorize");define('GET_ACCESS_TOKEN_URL' , "https://graph.qq.com/oauth2.0/token");define('GET_OPENID_URL' , "https://graph.qq.com/oauth2.0/me");保存2.打开application文件夹，在application下新建一个文件夹isetting,在isetting下建一个qq_setting.php文件，
打开qq_setting.php文件，输入如下代码： <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');/**
* @qq互联配置信息 * 默认开启get_user_info模块 * **/$config['inc_info'] = array(
array ( 'appid' => '101091331', 'appkey' => '7cb032049f2c900fea509424e614a979', 'callback' => 'http://test.com' ), array ( 'get_user_info' => '1', 'add_topic' => '0', 'add_one_blog' => '0', 'add_album' => '0', 'upload_pic' => '0', 'list_album' => '0', 'add_share' => '0', 'check_page_fans' => '0', 'add_t' => '0', 'add_pic_t' => '0', 'del_t' => '0', 'get_repost_list' => '0', 'get_info' => '0', 'get_other_info' => '0', 'get_fanslist' => '0', 'get_idollist' => '0', 'add_idol' => '0', 'del_idol' => '0', 'get_tenpay_addr' => '0', ) );保存说明：你需要把appid，appkey对应的键值修改成你刚刚申请的appid,appkey值，callback为回调地址（所谓回调地址就是登录成功后，返回到哪个页面），callback的值写你申请的时候做验证的那个地址。3.打开application下的libraries文件，新建一个文件夹tencent，在tencent里面新建一个文件oauth.php,打开这个文件，复制下面的代码进去：
<?php

保存说明：这段代码复制不过就行，不用做任何改动。这个是最核心的代码，代码比较多，但是功能代码就这些了，想想，在自己的网站上，别人用qq帐号就可以登录了，都不用注册，多方便啊，是吧，这样一想这些代码也不算多了。 4.建控制器。打开application下的controllers文件夹，在controllers下新建一个文件qq.php,打开qq.php,复制下面代码： <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); /* * @ qq登陆 注销 消息获取等 * @author */ class QQ extends CI_Controller { public function __construct() { parent::__construct(); session_start(); $this->load->helper('url'); //error_reporting(0); /*qq登陆*/ $this->load->library('tencent/oauth','oauth'); } public function index() { //验证是登陆还是回调 if($this->oauth->check_login() === 'false') { $this->oauth->qq_login(); } else { $this->oauth->qq_callback(); } } } 保存说明：这段代码不用做修改。
5.放置登录按钮，点击用QQ帐号登录按钮，跳转到QQ登录页面登录。
在你的登录页面放按钮的位置，写入：<div><a href="/qq"><img src="http://images.cnblogs.com/qq_login.png" width="110" /></a></div>保存
说明：样式你可自己调整，图片按钮可以从官网下载，地址：http://wiki.connect.qq.com/%E8%A7%86%E8%A7%89%E7%B4%A0%E6%9D%90%E4%B8%8B%E8%BD%BD#2.QQ.E7.99.BB.E5.BD.95.E6.A1.86.E6.A0.87.E5.87.86.E6.A0.B7.E5.BC.8F 到这里，QQ第三方登录接口就OK了，你打开你的登录页面，点击QQ登录的图片按钮，它会转到QQ登录页面登录，如果要上线，要用到别的功能，可在这几个文件上填代码就行了。
