thinkphp 6.0 swoole扩展websocket使用教程(think-swoole)
前言
最新版本的TP-SWOOLE变化很大，该文所提供的方法已经无法使用，可以参考 https://github.com/xavieryang007/think-swoole-demo/blob/master/doc/%E6%96%87%E6%A1%A3/4.1-websocket.md
介绍
即将推出的tp6.0，已经适配swoole.并推出think-swoole 3.0，并且默认适配了socketio。和2.0版本在使用方法上面有些许不同。
Websocket 继承与Http，进行websocket连接之前需要一次HTTP请求，如果当期地址支持websocket则返回101，然后进行连接。也就是说并不是我的服务支持websocket后，请求每个连接地址都可以进行websocket连接，而是需要预先适配才可以连接。

参数配置
如果要使用websocket需要在配置中启用,将websocket下的enable设置为true
'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' => [],
handler和parser大大方便了自定义websocket服务，默认系统集成socketio。
本文主要介绍如何使用socketio，这里假设大家有socketio有一定了解和使用基础。
socketIo默认会在请求地址后加相应的参数
同时，socketio默认情况下，会认为 http://url/socket.io/ 是支持websocket服务的地址。
而在tp-swoole3.0内部已经对该地址请求进行了处理
<?php namespace thinkswoolewebsocketsocketio; use thinkConfig; use thinkCookie; use thinkRequest; 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,插件注册采用了service方式进行了注册，可在tp-swoole 服务注册文件中查看路由注册信息,如果想自定义链接规则，则可以覆盖该路由。

WebsocketServer::class : HttpServer::class; $config = $this->app->config; $host = $config->get('swoole.server.host'); $port = $config->get('swoole.server.port'); $socketType = $config->get('swoole.server.socket_type', SWOOLE_SOCK_TCP); $mode = $config->get('swoole.server.mode', SWOOLE_PROCESS); static::$server = new $server($host, $port, $mode, $socketType); $options = $config->get('swoole.server.options'); static::$server->set($options); } }
Socketio默认使用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目录下新建websocket.php文件,其中需要注意，由于使用了反射，闭包参数名称不能随意定义，不然无法注入。第一个参数是websocket，是当前websocket的Server对象，第二个参数data是客户端发送的数据。其中socketio emit的第一个参数和Websocket::on的第一个参数一致，作为事件名称。
<?php /** * Author:Xavier Yang * Date:2019/6/5 * Email:499873958@qq.com */ use thinkswoolefacadeWebsocket; Websocket::on("test", function (thinkswooleWebsocket $websocket, $data) { //var_dump($class); $websocket->emit("test", "asd"); }); Websocket::on("test1", function ($websocket, $data) { $websocket->emit("test", "asd"); }); Websocket::on("join", function (thinkswooleWebsocket $websocket, $data) { $websocket->join("1"); });
参考如上方法即可使用全新的websocket服务。当然tp-swoole3.0同样还有许多其他的新功能，这些功能需要大家去摸索尝试。
我也会在接下来的文章中，一起与大家分享我的使用过程。
