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，並且預設適配了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連線之前需要一次HTTP請求，如果當期位址支援websocket則回傳101，然後進行連線。也就是說不是我的服務支援websocket後，請求每個連接位址都可以進行websocket連接，而是需要預先適配才可以連接。
參數配置
'server' => [ 'host' => '0.0.0.0', // 监听地址
'port' => 808, // 监听端口
'mode' => SWOOLE_PROCESS, // 运行模式 默认为SWOOLE_PROCESS
'sock_type' => SWOOLE_SOCK_TCP, // sock type 默认为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,// 开启websocket
'handler' => Handler::class, //自定义wbesocket绑定类
'parser' => Parser::class, //自定义解析类
'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' => [],登入後複製
handler和parser大大方便了自訂websocket服務，預設系統整合socketio。
本文主要介紹如何使用socketio，這裡假設大家有socketio有一定了解和使用基礎。
socketIo預設會在請求位址後加上對應的參數
同時，socketio預設會在請求位址後加上對應的參數
同時，socketio預設會在請求位址後加上對應的參數
同時，socketio預設情況下，會認為 http://url/socket.io / 是支援websocket服務的地址。
而在tp-swoole3.0內部已經對該位址請求進行了處理
<?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
);
}
}登入後複製
TP6.0,插件註冊採用了service方式進行了註冊，可在tp-swoole 服務註冊文件中查看路由註冊資訊,如果想自訂連結規則，則可以覆蓋該路由。

Websocket路由設定方法在app目錄下新建websocket.php檔案,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，是目前websocket的Server對象，第二個參數data是客戶端發送的資料。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。

############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流程。 ######更多ThinkPHP相關技術文章，請造訪###ThinkPHP使用教學###欄位進行學習！ ###
