【问题描述】:
我有一个硬件跟踪设备,我正在使用 PHP 套接字收听它。我将套接字文件作为守护程序文件运行,这意味着脚本将永远运行。但是运行了一段时间后,我得到了这个错误
对等方重置连接
我正在使用这个套接字库 https://github.com/navarr/Sockets 并将文件作为守护进程运行,我正在使用 forever
运行一段时间后出现此错误
<br />

我想知道究竟是什么导致了这个错误。我不希望我的脚本停止。为什么我收到对等方重置错误连接。我该如何解决这个问题
如果没有解决对等连接重置的解决方案,那么我是否有可能在收到错误 5 分钟后再次运行脚本对等连接重置。
为什么 5 分钟是因为套接字进入等待阶段,当永远尝试再次运行脚本时,它说地址已在使用中
代码:
<?php
use Navarr\Socket\Socket;
use Navarr\Socket\Server;
class EchoServer extends Server
{
const DEFAULT_PORT = 7;
public function __construct($ip = null, $port = self::DEFAULT_PORT)
{
parent::__construct($ip, $port);
$this->addHook(Server::HOOK_CONNECT, array($this, 'onConnect'));
$this->addHook(Server::HOOK_INPUT, array($this, 'onInput'));
$this->addHook(Server::HOOK_DISCONNECT, array($this, 'onDisconnect'));
$this->run();
}
public function onConnect(Server $server, Socket $client, $message)
{
echo 'Connection Established',"\n";
}
public function onInput(Server $server, Socket $client, $message)
{
echo 'Received "',$message,'"',"\n";
$client->write($message, strlen($message));
}
public function onDisconnect(Server $server, Socket $client, $message)
{
echo 'Disconnection',"\n";
}
}
由于错误出现在第 685 行中,因此下面的函数是写在 Socket.php 文件中的函数
protected static function exceptionOnFalse($resource, callable $closure)
{
$result = $closure($resource);
if ($result === false) {
throw new SocketException($resource);
}
return $result;
}
