前言
ThinkPHP即將迎來最新版本6.0,針對目前越來越流行Swoole,thinkphp也推出了最新的擴展think-swoole 3.0。
介紹
即將推出的tp6.0,已經適配swoole.並推出think-swoole 3.0,並且默認適配了socketio。和2.0版本在使用方法上面有些許不同。
Websocket 繼承與Http,進行websocket連接之前需要一次HTTP請求,如果當期地址支持websocket則返回101,然后進行連接。也就是說並不是我的服務支持websocket后,請求每個連接地址都可以進行websocket連接,而是需要預先適配才可以連接。

handler和parser大大方便了自定義websocket服務,默認系統集成socketio。
本文主要介紹如何使用socketio,這里假設大家有socketio有一定了解和使用基礎。
socketIo默認會在請求地址后加相應的參數

同時,socketio默認情況下,會認為 http://url/socket.io/ 是支持websocket服務的地址。

而在tp-swoole3.0內部已經對該地址請求進行了處理

<?phpnamespace think\swoole\websocket\socketio;use think\Config;use think\Cookie;use think\Request;class Controller{ protected $transports = ['polling', 'websocket']; public function upgrade(Request $request, Config $config, Cookie $cookie)
{ if (!in_array($request->param('transport'), $this->transports)) { return json(
[ 'code' => 0, 'message' => 'Transport unknown',
], 400
);
} if ($request->has('sid')) {
$response = response('1:6');
} else {
$sid = base64_encode(uniqid());
$payload = json_encode(
[ 'sid' => $sid, 'upgrades' => ['websocket'], 'pingInterval' => $config->get('swoole.websocket.ping_interval'), 'pingTimeout' => $config->get('swoole.websocket.ping_timeout'),
]
);
$cookie->set('io', $sid);
$response = response('97:0' . $payload . '2:40');
} return $response->contentType('text/plain');
} public function reject(Request $request)
{ return json(
[ 'code' => 3, 'message' => 'Bad request',
], 400
);
}
}

TP6.0,插件注冊采用了service方式進行了注冊,可在tp-swoole 服務注冊文件中查看路由注冊信息,如果想自定義鏈接規則,則可以覆蓋該路由。

Socketio默認使用demo

<!DOCTYPE html><html lang="en"><head>
<meta charset="UTF-8">
<title>Title</title>
<script src="./static/js/socket.io.js"></script></head><body><script>
const socket = io('http://localhost:808');
socket.emit("test", "your message");
socket.on("test",function(res){console.log(res)});</script></body></html>

Websocket路由配置方法
在app目錄下新建websocket.php文件,其中需要注意,由於使用了反射,閉包參數名稱不能隨意定義,不然無法注入。第一個參數是websocket,是當前websocket的Server對象,第二個參數data是客戶端發送的數據。其中socketio emit的第一個參數和Websocket::on的第一個參數一致,作為事件名稱。
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
<?php
use \think\swoole\facade\Websocket;
Websocket::on("test", function (\think\swoole\Websocket $websocket, $data) {
$websocket->emit("test", "asd");
});
Websocket::on("test1", function ($websocket, $data) {
$websocket->emit("test", "asd");
});
Websocket::on("join", function (\think\swoole\Websocket $websocket, $data) {
$websocket->join("1");
});

參考如上方法即可使用全新的websocket服務。當然tp-swoole3.0同樣還有許多其他的新功能,這些功能需要大家去摸索嘗試。
我也會在接下來的文章中,一起與大家分享我的使用過程。
