php 代码
<?php
$ws = new swoole_websocket_server("0.0.0.0", 9502);
// 设置配置
$ws->set(
array(
'daemonize' => false, // 是否是守护进程
'max_request' => 10000, // 最大连接数量
'dispatch_mode' => 2,
'debug_mode'=> 1,
// 心跳检测的设置，自动踢掉掉线的fd
'heartbeat_check_interval' => 5,
'heartbeat_idle_time' => 600,
)
);
//监听WebSocket连接打开事件
$ws->on('open', function ($ws, $request) {
$ws->push($request->fd, "hello, welcome to chatroom\n");
});
//监听WebSocket消息事件，其他：swoole提供了bind方法，支持uid和fd绑定
$ws->on('message', function ($ws, $frame) {
$msg = 'from'.$frame->fd.":{$frame->data}\n";
// 分批次发送
$start_fd = 0;
while(true)
{
// connection_list函数获取现在连接中的fd
$conn_list = $ws->connection_list($start_fd, 100); // 获取从fd之后一百个进行发送
var_dump($conn_list);
echo count($conn_list);
if($conn_list === false || count($conn_list) === 0)
{
echo "finish\n";
return;
}
$start_fd = end($conn_list);
foreach($conn_list as $fd)
{
$ws->push($fd, $msg);
}
}
});
//监听WebSocket连接关闭事件
$ws->on('close', function ($ws, $fd) {
echo "client-{$fd} is closed\n";
$ws->close($fd); // 销毁fd链接信息
});
$ws->start();
然后服务器端直接php swoole.php启动swoole就行，多个浏览器访问swoole.html页面，可以模拟聊天室，查看推送。
