yii+swoole上手websocket（1）—— demo

给自己找一点事情做~

说明：利用yii框架纯粹只是避免重复造轮子~~
先撸一个hello world吧

[Talk is cheap. Show me the code]

这一段是从官网copy下来的服务端代码，贼好使

use \Swoole\WebSocket\Server;
$server = new Server("0.0.0.0", 9501);
$server->on('open', function (Server $server, $request) {
    echo "server: handshake success with fd{$request->fd}\n";
});
$server->on('message', function (Server $server, $frame) {
    echo "receive from {$frame->fd}:{$frame->data},opcode:{$frame->opcode},fin:{$frame->finish}\n";
    $server->push($frame->fd, "this is server");
});
$server->on('close', function ($ser, $fd) {
    echo "client {$fd} closed\n";
});
$server->start();

再手撸一段客户端代码~

$cli = new \swoole_http_client('127.0.0.1', 9501);
$cli->setHeaders(['Trace-Id' => md5(time()),]);
$cli->on('message', function ($_cli, $frame) {
    var_dump($frame);
    $_cli->close();
});
$cli->upgrade('/', function ($cli) {
    echo $cli->body;
    echo 'upgrade'. PHP_EOL;
    $cli->push("hello world");
});

说明：
这里暂时不会考虑ssl等加密问题，一般情况下，需要加上ssl，也是通过一层nginx代理
