监听0.0.0.0时onClose重复回调

[52fhy]

监听本机公网IP时正常，监听0.0.0.0时不断触发onClose回调：

代码：

public function __construct() {
        $serv = new \swoole_websocket_server('0.0.0.0', '9501');

        $serv->set(array(
            'worker_num' => 8,
            'daemonize' => true,
            'max_request' => 1000,
            'max_conn' => 65000,
            'dispatch_mode' => 2,
            'debug_mode'=> 1,
            'task_worker_num'=>100,
            'log_file'    => "webServer.log",
            'heartbeat_check_interval'=>60,
            'heartbeat_idle_time' => 600, 
        ));
        $serv->on('Start', array($this, 'onStart'));
        $serv->on('WorkerStart', array($this, 'onWorkerStart'));
        $serv->on('Open', array($this, 'onOpen'));
        $serv->on('Message', array($this, 'onMessage'));
        $serv->on('Task',array($this,'onTask'));
        $serv->on('Finish',array($this,'onFinish'));
        $serv->on('Close', array($this, 'onClose'));
        $serv->start();
    }

public function onOpen(swoole_websocket_server $server, $request){
        $fd = $request->fd;
        MyEcho("new Client onOpen ----->fd: {$fd}");
    }

public function onClose( $serv, $fd, $from_id ) {
        MyEcho("client Close----->fd: {$fd}");
    }

版本： PHP 7.0.3+swoole1.8.6

[matyhtf]

这里关闭的fd并不相同，怎么证明是重复回调？

[52fhy]

@matyhtf 没有调用onOpen

[matyhtf]

升级一下swoole的版本试试吧。

[52fhy]

@matyhtf 虽然没有调用onOpen，但是发现调用了Connect：

$serv = new \swoole_websocket_server('0.0.0.0', '9501');

$serv->set(array(
            'worker_num' => 8,
            'daemonize' => true,
            'max_request' => 1000,
            'max_conn' => 65000,
            'dispatch_mode' => 2,
            'debug_mode'=> 1,
            'task_worker_num'=>100,
            'log_file'    => "webServer.log",
            'buffer_output_size' => 32 * 1024 *1024,
            'heartbeat_check_interval'=>60,
            'heartbeat_idle_time' => 600, 
        ));
        $serv->on('Start', array($this, 'onStart'));
        $serv->on('WorkerStart', array($this, 'onWorkerStart'));
        $serv->on('Open', array($this, 'onOpen'));
        $serv->on('Message', array($this, 'onMessage'));
        $serv->on('Task',array($this,'onTask'));
        $serv->on('Finish',array($this,'onFinish'));
        $serv->on('Close', array($this, 'onClose'));
        $serv->on('Connect', function ($server, int $fd, int $from_id){
            My_Echo("client Connect----->fd: {$fd}" .'---'.$from_id);
        });
        $serv->start();

目前还不清楚是怎么调用的。

原因已找到，是有客户端一直在进行tcp请求，这个客户端是我们配置的阿里云负载均衡器的健康检查，每隔2s运行一次。感谢您的回复！
