GatewayWorker 如何用AsyncTcpConnection协议，来作为客户端连接别人的socket.

有类似的Demo代码，辛苦各位贴出来，给我学习一下。

1、既然是刚接触，建议老老实实看手册，使用workerman进行业务开发需要一定的功底，否则很容易自己给自己埋很多不是坑的坑；
2、至于使用 workerman 或者 gatewayworker 作为客户端，手册上就说的很详细了，DEMO代码也有，怎么整合到自己的上下文也不是什么难事，难的还是你没认真看手册：
http://doc.workerman.net/faq/as-wss-client.html

每天都在看手册，没写过代码，所以不是很懂，但是我想把AsyncTcpConnection 发出的连接也当作一个client用，这样发消在Events中调用，通迅就比较方便。

我定议了一个协议 Xml
用的AsyncTcpConnection

新建一个Gateway,运行就报错
这个是gateway

$internal_gateway = new Gateway("Xml://192.168.3.8:7273");
$internal_gateway->name='sis_client';
// #### 不要与原来start_gateway.php的一样####
// #### 比原来跨度大一些，比如在原有startPort基础上+1000 ####
$internal_gateway->startPort = 4300;
// #### 这里设置成与原start_gateway.php 一样 ####
$internal_gateway->registerAddress = '127.0.0.1:1238';

这个是定义的协议，

public static function input($recv_buffer,AsyncTcpConnection $connection )
{

        if(strlen($recv_buffer) < 1)
        {
            // 不够10字节，返回0继续等待数据
            return 0;
        }
        // 返回包长，包长包含 头部数据长度+包体长度
        $total_len = base_convert(substr($recv_buffer, 0, 10), 10, 10);
        return $total_len;
    }

    public static function decode($recv_buffer)
    {
        // 请求包体
        $body = $recv_buffer;
        return simplexml_load_string($body);
    }

    public static function encode($xml_string)
    {
        // 包体+包头的长度
        //$total_length = strlen($xml_string)+10;
        // 长度部分凑足10字节，位数不够补0
        //$total_length_str = str_pad($total_length, 10, '0', STR_PAD_LEFT);
        // 返回数据
        //return $total_length_str . $xml_string;
        return  $xml_string;
    }
}

应该是建立Gateway 不支持这样连接远程，但我不明白怎么样才能连接远程地址，让Gateway 作为一个客户端。
