    public function tiaozhuan()
    {
        $info = getData("system_config", array("type" => "pre_auth_code"), array(), 1);    ////获取保存在数据库中的pre_auth_code
        $pre_auth_code = $info["value"];
        $back_url = "http://www.xxxxxx.com/index.php/$APPID$/callback";   //后台设置的回调地址，用户扫完二维码之后会跳转到这个连接    
        $url = "https://mp.weixin.qq.com/cgi-bin/componentloginpage?component_appid=wxcda7bf3c4bf44cdc&pre_auth_code=".$pre_auth_code."&redirect_uri=".$back_url;
        header("Location:".$url);
    }

        $info = getData("system_config", array("type" => "component_access_token"), array() , 1); //获取保存在数据库中的component_access_token
        $component_access_token = $info["value"];
        $url = "https://api.weixin.qq.com/cgi-bin/component/api_query_auth?component_access_token=".$component_access_token;
        $auth_code = $_GET["auth_code"];
        $post = array(
            "component_appid" => $this->appid,    //应用的appid
            "authorization_code"    => $auth_code,

    }

//获取授权方的公众号帐号基本信息
    public function demo6()
    {
