信息

enableKeepAlive 配置似乎不起作用，文档甚至没有解释如何正确设置它。 http://socketo.me/docs/websocket

我通过使用手机打开连接然后关闭 wifi 和数据来测试它。客户端从未断开连接。

我的代码：chat-server.php

<?php
use Ratchet\Server\IoServer;
use Ratchet\Http\OriginCheck;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use MyApp\Chat;

require dirname(__DIR__) . '/vendor/autoload.php';

$loop = React\EventLoop\Factory::create();
$loop->run();
$checkedApp = new WsServer( new Chat() );
$checkedApp->enableKeepAlive($loop, 5);
//$checkedApp = new OriginCheck(new WsServer( new Chat() ), array('localhost'));
$checkedApp = new OriginCheck($checkedApp);
$checkedApp->allowedOrigins[] = 'mywebsite.com';

$server = IoServer::factory(
    new HttpServer(
        $checkedApp
    ),
    8082
);

//works, so loop works
/*
$server->loop->addPeriodicTimer(5, function () use ($server) {        
    foreach ($server->app->clients as $client) {                  
            $client->send("hello client");          
    }
});
*/

$server->run();

太棒了，所以它被覆盖在这个页面上： http://socketo.me/docs/migration-3

创建服务器后，然后启用KeepAlive：

<?php
use Ratchet\Server\IoServer;
use Ratchet\Http\OriginCheck;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use MyApp\Chat;

require dirname(__DIR__) . '/vendor/autoload.php';

//$loop = React\EventLoop\Factory::create();
//$loop->run();
$checkedApp = new WsServer( new Chat() );
//$checkedApp->enableKeepAlive($loop, 5);
//$checkedApp = new OriginCheck(new WsServer( new Chat() ), array('localhost'));
$checkedAppToPass = new OriginCheck($checkedApp);
$checkedAppToPass->allowedOrigins[] = 'mywebsite.com';

$server = IoServer::factory(
    new HttpServer(
        $checkedAppToPass
    ),
    8082
);

$checkedApp->enableKeepAlive($server->loop, 10);

//works, so loop works
/*
$server->loop->addPeriodicTimer(5, function () use ($server) {        
    foreach ($server->app->clients as $client) {                  
            $client->send("hello client");          
    }
});
*/

$server->run();
