error))        {           echo "
error:
" . $msg->error;           echo "
msg  :
" . $msg->error_description;           exit;        }     }      //Step3：使用Access Token来获取用户的OpenID     $params = array();     parse_str($response, $params);     $graph_url = "https://graph.qq.com/oauth2.0/me?access_token=".$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);     if (isset($user->error))     {        echo "
error:
" . $user->error;        echo "
msg  :
" . $user->error_description;        exit;     }     echo("Hello " . $user->openid);  }  else   {     echo("The state does not match. You may be a victim of CSRF.");  }?>
