回调属性 - onError

说明:

callback Worker::$onError

当客户端的连接上发生错误时触发。

目前错误类型有

1、调用Connection::send由于客户端连接断开导致的失败 (code:WORKERMAN_SEND_FAIL msg:client closed)

2、在触发onBufferFull后，仍然调用Connection::send，并且发送缓冲区仍然是满的状态，导致发送失败 (code:WORKERMAN_SEND_FAIL msg:send buffer full and drop package)

3、使用AsyncTcpConnection异步连接失败时 (code:WORKERMAN_CONNECT_FAIL msg:stream_socket_client返回的错误消息)

回调函数的参数

$connection

范例

use WorkermanWorker;
require_once __DIR__ . '/Workerman/Autoloader.php';
$worker = new Worker('websocket://0.0.0.0:8484');
$worker->onError = function($connection, $code, $msg)
{
    echo "error $code $msgn";
};
// 运行worker
Worker::runAll();
