thinkphp 6.0 swoole擴展websocket使用教程-有解無憂

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.并推出think-swoole 3.0，并且默認適配了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則回傳101，然后進行連接，也就是說并不是我的服務支持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，

引數配置

'server' => [ 'host' => '0.0.0.0', // 監聽地址

'port' => 808, // 監聽埠

'mode' => SWOOLE_PROCESS, // 運行模式默認為SWOOLE_PROCESS

'sock_type' => SWOOLE_SOCK_TCP, // sock type 默認為SWOOLE_SOCK_TCP

'options' => [ 'pid_file' => runtime_path() . 'swoole.pid', 'log_file' => runtime_path() . 'swoole.log', 'daemonize' => false, // Normally this value should be 1~4 times larger according to your cpu cores.

'reactor_num' => swoole_cpu_num(), 'worker_num' => swoole_cpu_num(), 'task_worker_num' => 4,//swoole_cpu_num(),

'enable_static_handler' => true, 'document_root' => root_path('public'), 'package_max_length' => 20 * 1024 * 1024, 'buffer_output_size' => 10 * 1024 * 1024, 'socket_buffer_size' => 128 * 1024 * 1024, 'max_request' => 3000, 'send_yield' => true,

],

], 'websocket' => [ 'enabled' => true,// 開啟websocket

'handler' => Handler::class, //自定義wbesocket系結類

'parser' => Parser::class, //自定義決議類

'route_file' => base_path() . 'websocket.php', 'ping_interval' => 25000, 'ping_timeout' => 60000, 'room' => [ 'type' => TableRoom::class, 'room_rows' => 4096, 'room_size' => 2048, 'client_rows' => 8192, 'client_size' => 2048,

],

], 'auto_reload' => true, 'enable_coroutine' => true, 'resetters' => [], 'tables' => [],

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引數

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 服務注冊檔案中查看路由注冊資訊,如果想自定義鏈接規則，則可以覆寫該路由，

Socketio默認使用demo

Websocket路由配置方法

在app目錄下新建websocket.php檔案,其中需要注意，由于使用了反射，閉包引數名稱不能隨意定義，不然無法注入，第一個引數是websocket，是當前websocket的Server物件，第二個引數data是客戶端發送的資料，其中socketio emit的第一個引數和Websocket::on的第一個引數一致，作為事件名稱，
