thinkphp 6.0 swoole扩展websocket使用教程

前言

thinkphp即将迎来最新版本6.0，针对目前越来越流行swoole，thinkphp也推出了最新的扩展think-swoole 3.0。

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

'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

<?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。

*/

protected static $server; public function register()

{ $this->iswebsocket = $this->app->config->get('swoole.websocket.enabled', false); $this->app->bind(server::class, function () { if (is_null(static::$server)) { $this->createswooleserver();

} return static::$server;

}); $this->app->bind('swoole.server', server::class); $this->app->bind(swoole::class, function (app $app) { return new swoole($app);

}); $this->app->bind('swoole', swoole::class);

} public function boot(route $route)

{ $this->commands(servercommand::class); if ($this->iswebsocket) {

$route->group(function () use ($route) {

$route->get('socket.io/', '@upgrade');

$route->post('socket.io/', '@reject');

})->prefix(controller::class)->middleware(middleware::class);

}

} /**

* create swoole server.

*/

protected function createswooleserver()

{

$server = $this->iswebsocket ? 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 \think\swoole\facade\websocket;

websocket::on("test", function (\think\swoole\websocket $websocket, $data) { //var_dump($class);

$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");

});

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。
