Yii2结合Workerman的websocket示例详解

前言

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
