NodeJS -建立具有HTTPS协议的连接WebSocket

Question

我对HTTPS和WebSocket连接有问题(我使用Node.JS作为服务器)。我用OpenSSL生成了SSL证书，并使用以下代码将它们导入服务器：

const https = require('https');
var app = express();
...
const WebSocket = require('ws');
...
var serverHttps = https.createServer({
        key: fs.readFileSync(path.join(pathCertificati, 'key.pem')),
        cert: fs.readFileSync(path.join(pathCertificati, 'cert.pem'))
    }, app).listen(3000, () => {
    console.log('In ascolto sulla porta 3000 HTTPS.')
    })

const wss = new WebSocket.Server({
    server: serverHttps, 
    adress: '192.168.12.40',
    port: 9000
});

有了这段代码，我应该有一个WebSocket来处理HTTPS连接，对吗？

客户端，我有以下代码：

socket = new WebSocket("wss://192.168.12.40:9000");
socket.onopen = function ()...
socket.onclose = function ()...
socket.onerror = function (error) {
        console.log("Errore nella connessione!");
        console.log(error);
    }

当我使用address：https://192.168.12.40:3000和上面的代码加载页面时，会出现错误消息：

指向'wss://192.168.12.40:9000/‘的WebSocketScript.js:26 WebSocket连接失败:连接建立中的错误:WebSocketScript.js:26

您对在HTTPS页面上建立WebSocket连接有什么想法吗？非常感谢。

我已经找到了解决这个问题的办法。解决办法是：

服务器端代码：

var serverHttps = https.createServer({
        key: fs.readFileSync(path.join(pathCertificati, 'key.pem')),
        cert: fs.readFileSync(path.join(pathCertificati, 'cert.pem'))

    }, app).listen(3000, () => {
        // Messaggio di attivazione del server in ascolto sulla porta 3000
        console.log('Listening ' + 3000 + ' HTTPS.');
    })

serverHttps.on('upgrade', function upgrade(request, socket, head) {
    const pathname = url.parse(request.url).pathname;

    if (pathname === "/") {
        wss.handleUpgrade(request, socket, head, function done(ws) {
            wss.emit('connection', ws, request);
        });
    }
});

// Create WebSocket
const wss = new WebSocket.Server({ noServer: true });

wss.on('error', function () {...}
wss.on('connection', function (ws) {...}

客户端：

socket = new WebSocket("wss://192.168.12.40:3000);

这是服务器端使用的相同地址，它触发事件“serverHttps.on(‘升级’)”
