我正在尝试在我的网络服务器上创建一个网络套接字。我想从我的客户端连接到 websocket 以更新网站上的信息。但是，当我尝试连接时，我在 Postman 中收到以下错误：
错误：意外的服务器响应：101 握手细节 请求网址：https://example.com:8443/radar 请求方式：GET 状态代码：101 切换协议 请求标头 Sec-WebSocket-版本：13 连接：升级 升级：网络套接字 Sec-WebSocket-Extensions：permessage-deflate； client_max_window_bits 主机：example.com:8443 响应头 日期：2023 年 3 月 11 日星期六 02:20:55 GMT 服务器：阿帕奇/2 升级：网络套接字 X-Powered-By：Phusion Passenger 5.3.7 状态：101 切换协议 变化：用户代理 内容长度：2
要监听端口 8443，我的 VirtualHosts (httpd.conf) 中有以下内容：
Listen 8443
<VirtualHost 123.123.123.123:8443>

NodeJS脚本的代码如下：
雷达.js：
const http = require('http');
const WebSocketServer = require('websocket').server;
const fs = require('fs')
function writeHtml(outputStream) {
const inputStream = fs.createReadStream('index.html')
inputStream.pipe(outputStream)
outputStream.on('finish', () => {
console.log('served')
outputStream.end();
})
outputStream.on('error', (e) => {
console.error('errors', e)
outputStream.end();
})
}
const server = http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/html'});
writeHtml(res)
})
server.listen(process.env.PORT || 8443);
const wsServer = new WebSocketServer({
httpServer: server
});
wsServer.on('request', function(request) {
console.log("ws received")
const connection = request.accept(null, request.origin);
connection.on('message', function(message) {
console.log('Received Message:', message.utf8Data);
connection.sendUTF('Hi this is WebSocket server!');
});
connection.on('close', function(reasonCode, description) {
console.log('Client has disconnected.');
});
});
index.html:
<!DOCTYPE html>
<html>
<head>
<title>WebSocket Playground</title>
</head>
<body>
</body>
<script>
const ws = new WebSocket('wss://' + location.host);
ws.onopen = function() {
console.log('WebSocket Client Connected');
ws.send('Hi this is web client.');
};
ws.onmessage = function(e) {
console.log("Received: '" + e.data + "'");
};
</script>
</html>
我也试过修改 VirtualHosts，但没有任何效果。
如果能得到任何帮助，我将不胜感激，我也没有使用代理（如 Cloudflare 等）。谢谢。
