(同一套代码, pc端不能登录, 但是, 手机和平板都可以正常登录.....)

1. 首先是库文件, 登录->授权->token->openid->获取用户信息

 class QQ
 {
     public $appid = '';
     public $appkey = '';
     public $scope = 'get_user_info'; //权限用逗号隔开
     public $callback = '';

     public $get_auth_code_url = 'https://graph.qq.com/oauth2.0/authorize';
     public $get_access_token_url = 'https://graph.qq.com/oauth2.0/token';
     public $get_openid_url = 'https://graph.qq.com/oauth2.0/me';
     public $get_user_info_url = 'https://graph.qq.com/user/get_user_info';

     public $access_token = '';
     public $openid = '';

     public function __construct($callback_url)
     {
         $this->callback = $callback_url;
     }

     public function login()
     {
         $objRedis = Fun::getInstance()->getRedis();
         $ip = Fun::getInstance()->getIP();

         //-------生成唯一随机串防CSRF攻击
         $state = md5(uniqid(rand(), TRUE));
         $objRedis->iset('qqsdk'.$ip, 'state', $state);

         //-------构造请求参数列表
         $arrQueryArg = array(
             'response_type' => 'code',
             'client_id' => $this->appid,
             'redirect_uri' => $this->callback,
             'state' => $state,
             'scope' => $this->scope
         );

         $uri = http_build_query($arrQueryArg);
         $login_url =  $this->get_auth_code_url.'?'.$uri;

         header("Location:$login_url");
     }

     public function callback()
     {
         $objRedis = Fun::getInstance()->getRedis();
         $ip = Fun::getInstance()->getIP();
         $state = $objRedis->iget('qqsdk'.$ip, 'state');

         //--------验证state防止CSRF攻击
         if($_GET['state'] != $state){
             exit('30001');
         }

         //-------请求参数列表
         $arrTokenArg = array(
             'grant_type' => 'authorization_code',
             'client_id' => $this->appid,
             'redirect_uri' => $this->callback,
             'client_secret' => $this->appkey,
             'code' => $_GET['code']
         );
         //------构造请求access_token的url
         $uri = http_build_query($arrTokenArg);
         $token_url =  $this->get_access_token_url.'?'.$uri;
         $response = Fun::getInstance()->curl_get($token_url);
         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($msg->error)){
                 var_dump($msg->error, $msg->error_description);
             }
         }

         $params = array();
         parse_str($response, $params);

         //---------获取openid
         $arrTokenArg = array(
             'access_token' =>$params['access_token']
         );
         $uri = http_build_query($arrTokenArg);
         $openid_url =  $this->get_openid_url.'?'.$uri;
         $response = Fun::getInstance()->curl_get($openid_url);

         //--------检测错误是否发生
         if(strpos($response, 'callback') !== false){

             $lpos = strpos($response, '(');
             $rpos = strrpos($response, ')');
             $response = substr($response, $lpos + 1, $rpos - $lpos -1);
         }

         $user = json_decode($response);
         if(isset($user->error)){
             var_dump($user->error, $user->error_description);exit;
         }

         return array(
             'access_token' => $params['access_token'],
             'openid' => $user->openid
             );

     }

     public function get_user_info()
     {
         $qq_safe_info = $this->callback();
         $access_token = $qq_safe_info['access_token'];
         $openid = $qq_safe_info['openid'];
         $user_info_url = "{$this->get_user_info_url}?access_token={$access_token}&oauth_consumer_key={$this->appid}&openid={$openid}&format=json";
         $info = Fun::getInstance()->curl_get($user_info_url);
         return array(
             'openid' => $openid,
             'user_info' => $info
             );
         // $json_user_info = Fun::getInstance()->curl_get($user_info_url);
         // return json_decode($json_user_info);
     }
 }

2. 其次是控制器调用代码, 调用QQ登录库文件, 以及获取并记录QQ登录信息

 public function login()
     {
         $this->getLib('QQ', $this->qq_callback_url)->login();
     }

     public function callback()
     {
         $user_info = $this->getLib('QQ', $this->qq_callback_url)->get_user_info();
         // $user_ip = Fun::getInstance()->getIP();
         $objRedis = $this->getLib('iredis');
         $objRedis->iset('qqsdk'.$this->cookierand, 'qquser', $user_info['user_info']);
         $objUserInfo = json_decode($user_info['user_info']);
         $this->loadBusiness('Bbs')->qqregister($user_info['openid'], $objUserInfo->nickname, $objUserInfo->figureurl_qq_1);
         echo "<script>window.opener.location.reload();window.close();</script>";
     }

其中第14行代码的作用是, 刷新父窗口&&关闭弹出的QQ登录窗口

3. 最后是HTML代码, 在网页上放一个QQ登录按钮

 <a href="#" onclick='toQzoneLogin()'><img src="http://zbf-img.qiniudn.com/qq_login.png" alt="QQ登录^_^" title="QQ登录^_^"></a>
 <script type="text/javascript">
         //qq登录
         var childWindow;
         function toQzoneLogin()
         {
             childWindow = window.open("http://www.zhangzhibin.com/qq/index/login","TencentLogin","width=450,height=320,menubar=0,scrollbars=1, resizable=1,status=1,titlebar=0,toolbar=0,location=1");
         }
     </script>
