(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>
