本文主要给大家介绍了关于Yii2结合Workerman的websocket的相关内容，两者都是好东西，我就想着能不能结合起来，这样Yii2出现瓶颈的时候有些业务就可以平滑地迁移到Workerman中。下面话不多说了，来随着小编来一起看看详细的介绍吧
步骤如下
1、安装workerman
composer require workerman/workerman
2、启动workerman
创建commands/WorkermanWebSocketController.php文件
创建actionIndex()函数，用来启动，代码如下
public function actionIndex() { if ('start' == $this->send) { try { $this->start($this->daemon); } catch (\Exception $e) { $this->stderr($e->getMessage() . "\n", Console::FG_RED); } } else if ('stop' == $this->send) { $this->stop(); } else if ('restart' == $this->send) { $this->restart(); } else if ('reload' == $this->send) { $this->reload(); } else if ('status' == $this->send) { $this->status(); } else if ('connections' == $this->send) { $this->connections(); } }
添加初始化模块
public function initWorker() { $ip = isset($this->config['ip']) ? $this->config['ip'] : $this->ip; $port = isset($this->config['port']) ? $this->config['port'] : $this->port; $wsWorker = new Worker("websocket://{$ip}:{$port}"); // 4 processes $wsWorker->count = 4; // Emitted when new connection come $wsWorker->onConnect = function ($connection) { echo "New connection\n"; }; // Emitted when data received $wsWorker->onMessage = function ($connection, $data) { // Send hello $data $connection->send('hello ' . $data); }; // Emitted when connection closed $wsWorker->onClose = function ($connection) { echo "Connection closed\n"; }; }
添加启动模块
/** * workman websocket start */ public function start() { $this->initWorker(); // 重置参数以匹配Worker global $argv; $argv[0] = $argv[1]; $argv[1] = 'start'; if ($this->daemon) { $argv[2] = '-d'; } // Run worker Worker::runAll(); }
添加停止模块
/** * workman websocket stop */ public function stop() { $this->initWorker(); // 重置参数以匹配Worker global $argv; $argv[0] = $argv[1]; $argv[1] = 'stop'; if ($this->gracefully) { $argv[2] = '-g'; } // Run worker Worker::runAll(); }
添加重启模块
/** * workman websocket restart */ public function restart() { $this->initWorker(); // 重置参数以匹配Worker global $argv; $argv[0] = $argv[1]; $argv[1] = 'restart'; if ($this->daemon) { $argv[2] = '-d'; } if ($this->gracefully) { $argv[2] = '-g'; } // Run worker Worker::runAll(); }
添加重载模块
/** * workman websocket reload */ public function reload() { $this->initWorker(); // 重置参数以匹配Worker global $argv; $argv[0] = $argv[1]; $argv[1] = 'reload'; if ($this->gracefully) { $argv[2] = '-g'; } // Run worker Worker::runAll(); }
添加状态模块
/** * workman websocket status */ public function status() { $this->initWorker(); // 重置参数以匹配Worker global $argv; $argv[0] = $argv[1]; $argv[1] = 'status'; if ($this->daemon) { $argv[2] = '-d'; } // Run worker Worker::runAll(); }
添加链接数模块
/** * workman websocket connections */ public function connections() { $this->initWorker(); // 重置参数以匹配Worker global $argv; $argv[0] = $argv[1]; $argv[1] = 'connections'; // Run worker Worker::runAll(); }
3、前端调用
<script> // Create WebSocket connection. const ws = new WebSocket('ws://{{ app.request.hostName }}:2347/'); // 这里是获取的网站的域名，测试的时候可以改为自己的本地的ip地址 // Connection opened ws.addEventListener('open', function (event) { ws.send('Hello Server!'); }); // Listen for messages ws.addEventListener('message', function (event) { console.log('Message from server ', event.data); }); setTimeout(function() { ws.send('ssssss'); }, 10000); </script>
4、config参数配置
修改console.php并添加如下代码
'controllerMap' => [ 'workerman-web-socket' => [ 'class' => 'app\commands\WorkermanWebSocketController', 'config' => [ 'ip' => '127.0.0.1', 'port' => '2346', 'daemonize' => true, ], ], ],
5、nginx配置
为什么会用 nginx， 我们正常部署上线是不可能直接使用ip的，这个户存在安全隐患，最好是绑定一个域名
server { charset utf-8; client_max_body_size 128M; listen 2347; server_name ; # 这里改为自己的域名 access_log /xxx.workerman.access.log; # 换成自己服务器的nginx日志路径 error_log /xxx.workerman.error.log; # 换成自己服务器的nginx日志路径 location / { proxy_pass :2346; # 代理2346 也可以根据项目配置为自己的端口 proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } }
重新nginx
nginx -s relad 或者 sudo nginx -s reload
然后将第3步的代码加入自己做的视图中，如果没有问题的话，websocket启动后就能正常通讯了。
6、启动workerman websocket
// 启动 ./yii workerman-web-socket -s start -d
如果没有问题的话会得到类似如下的结果
