websocket如何在Yii2中使用？很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。
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 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.
