自定义文本协议，服务端丢消息

poisonbian 更新于2019-10-30

自定义的文本格式协议，格式很简单，用\r\n\r\n来分隔数据。代码见最下方。

现在的情况是这样子的，我通过tcp客户端发起一次请求，传输5个文本包，服务端的日志来看，这5个包确实都接收到了（protocol的input中的日志被打印出来了），但是并没有触发onMessage的操作。

进一步定位，protocol中的decode函数压根都没有被调用，下面输出的内容中可以看到，5个包都正常收到了，解析length也正确，就是没有触发decode操作。。。

服务端代码

客户端调用的代码

<?php 
$host = 'localhost';
$port = 8300;
$timeout = 1;
$eof = "\r\n\r\n";

$socket = fsockopen($host, $port, $errno, $errstr, $timeout);

for ($i = 0; $i < 20; $i++)
{
    fwrite($socket, 'testing' . $eof);
}

fclose($socket);
echo "done\n";
