Question

这是连接仍处于活动状态时我正在运行的当前WebSocket循环。但是经过11小时的持续连接，我收到了一个异常

"exception":"[object] (Amp\\Websocket\\ClosedException(code: 1006): The connection was closed: Client closed the underlying TCP connection at ...

如何检查关闭的连接或异常本身？，这样我就可以正确结束脚本逻辑而不会突然失败。

     \Amp\Loop::run(function () use ($fn, $st)
        {
            $connection = yield \Amp\Websocket\connect('wss://URL');

            yield $connection->send('{"action":"auth","params":"KEYID"}');
            yield $connection->send('{"action":"subscribe","params":"'.$st.'"}');

            $i = 0;

            while ($message = yield $connection->receive()) 
            {
                $i++;
                $payload = yield $message->buffer();

                $r = $fn($payload, $i);

                if ($r == false) {
                    $connection->close();
                    break;
                }
            }
        }
    );

我正在使用以下Amphp Websocket：https://github.com/amphp/websocket-client

谢谢！

我确实找到了解决方案，方法是查找ClosedException并在抛出之后运行其他任务。

\Amp\Loop::run(function () use ($fn, $st)
    {
        try 
        {
            $connection = yield \Amp\Websocket\connect('wss://URL');

            yield $connection->send('{"action":"auth","params":"KEYID"}');
            yield $connection->send('{"action":"subscribe","params":"'.$st.'"}');

            $i = 0;

            while ($message = yield $connection->receive()) 
            {
                $i++;
                $payload = yield $message->buffer();

                $r = $fn($payload, $i);

                if ($r == false) {
                    $connection->close();
                    break;
                }
            }
        }
        catch (\Amp\Websocket\ClosedException $e) 
        {
            // do something here
        }
    }
);

如何使用Amphp捕获php websocket断开的TCP连接异常？
