带有Workerman - nginx配置的PHP websockets
带有Workerman - nginx配置的PHP websockets
提问于 2020-07-07 20:53:52
我正在尝试在我的项目中使用Workerman，但在nginx配置方面遇到了问题。我在本地机器上使用docker，在本地主机文件中，socket.my-app.local被转换为127.0.0.1。我按照nginx反向代理的说明进行了设置，如下所示：
server {
listen 80;
listen [::]:80;
server_name socket.my-app.local;
location /socket.io/ {
proxy_pass http://localhost:2020/socket.io/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header X-Real-IP $remote_addr;
}
location / {
proxy_pass http://localhost:2020;
}
}我的PHP worker应该是websocket服务器，配置如下：
require_once __DIR__ . '/../vendor/autoload.php';
use Workerman\Worker;
// Create a Websocket server
$ws_worker = new Worker("websocket://0.0.0.0:2020");
// 4 processes
$ws_worker->count = 4;
// Emitted when new connection come
$ws_worker->onConnect = function($connection) {
echo "New connection\n";
};
// Emitted when data received
$ws_worker->onMessage = function($connection, $data) {
// Send hello $data
$connection->send('hello ' . $data);
};
// Emitted when connection closed
$ws_worker->onClose = function($connection) {
echo "Connection closed\n";
};
// Run worker
Worker::runAll();和我正在测试的html文件：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Workerman Sockets Test</title>
</head>
<body>
<h3>Hello</h3>
<script type="text/javascript">
var socket = new WebSocket("ws://socket.my-app.local:2020/socket.io");
socket.onopen = function() {
alert("Connection established.");
};
socket.onclose = function(event) {
if (event.wasClean) {
alert('The connection is closed.');
} else {
alert('Connection failure'); // for example, the server process is "killed"
}
alert('Code: ' + event.code + ' reason: ' + event.reason);
};
socket.onmessage = function(event) {
alert("Received data: " + event.data);
};
socket.onerror = function(error) {
alert("Error: " + error.message);
};
</script>
</body>
</html>我无法连接到ws服务器，我不确定如何测试，在这一点上它出了问题。
会不会是因为php-fpm和webserver在不同的码头容器上？

问题是docker容器使用内部命名空间进行通信，因此我必须将localhost更改为容器名称，本例中为php-fpm，我还必须在well服务器容器上打开websocket端口，以及侦听well服务器上端口，以便代理这些请求。
server {
listen 80;
listen 2020;
listen [::]:80;
listen [::]:2020;
server_name socket.my-app.local;
location /socket.io/ {
proxy_pass http://php-fpm:2020;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header X-Real-IP $remote_addr;
}
location / {
}
}在我的码头上-作曲
services
webserver:
...
ports:
- "80:80"
- "2020:2020"
