Swoole ( TCP / UDP / Http / Websocket )

TCP - Server/Client

UDP - Server/Client

HttpServer

on('request', function($request, $response) {
	$response->cookie('mingzi', 'neirong', time() + 1800);
	$response->end(json_encode($request->get));
});

$http->start();

---

有静态资源的HttpServer

set([
	'enable_static_handler' => true,
	'document_root' => '/Applications/MAMP/htdocs/swoole学习/swoole_demo/data'
]);

$http->on('request', function($request, $response) {
	$response->cookie('mingzi', 'neirong', time() + 1800);
	$response->end(json_encode($request->get));
});

$http->start();

---

WebSocket

set([
	'enable_static_handler' => true,
	'document_root' => '/Applications/MAMP/htdocs/swoole学习/swoole_demo/data'
]);

// 监听ws连接打开事件
$server->on('open', 'onOpen');
function onOpen($server, $request) {
	echo $request->fd;
};

// 监听ws消息事件
$server->on('message', function ($server, $frame) {
	echo "recive from {$frame->fd} : {$frame->data}, opcode : {$frame->opcode}, fin : {$frame->finish}\n";
	$server->push($frame->fd, '我收到了 回给你一句话');
});

$server->on('close', function ($ser, $fd) {
	echo "client {$fd} closed\n";
});

$server->start();
