        // 获取协议地址
        $http_type = ((isset($_SERVER['HTTPS'])
            && $_SERVER['HTTPS'] == 'on')
            || (isset($_SERVER['HTTP_X_FORWARDED_PROTO'])
                && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https'))
            ? 'https://' : 'http://';
        
        // 不包含当前文件和请求参数
        $hereURL =  $http_type . dirname($_SERVER['SERVER_NAME'] . $_SERVER["REQUEST_URI"]) . '/' ;
        
        // 完整地址
        $fUrl = $http_type . $_SERVER['SERVER_NAME'].':'.$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
