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']) "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 www.gowhich.com; # 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 http://127.0.0.1:2346; # 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

$ ./yii workerman-web-socket -s start -d
Workerman[workerman-web-socket] start in DAEMON mode
----------------------- WORKERMAN -----------------------------
Workerman version:3.5.13   PHP version:7.1.16
------------------------ WORKERS -------------------------------
user   worker  listen      processes status
durban  none   websocket://127.0.0.1:2346 4   [OK] 
----------------------------------------------------------------
Input "php workerman-web-socket stop" to stop. Start success.

7、其他

commands/WorkermanWebSocketController.php 完整代码如下

<"\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();
  }
 }

 public function initWorker()
 {
  $ip = isset($this->config['ip']) "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('dddd hello ' . $data);
  };

  // Emitted when connection closed
  $wsWorker->onClose = function ($connection) {
   echo "Connection closed\n";
  };
 }

 /**
  * 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();
 }

 /**
  * 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();
 }

 /**
  * 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();
 }

 /**
  * 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();
 }

 /**
  * 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();
 }

 /**
  * 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();
 }
}
