如何 运行 ws 和 wss 上的 websocket 服务器同时相互通信或同步数据?还是 HTTP 上的 WSS 和 HTTPS 上的 WS?

How to run a websocket server on ws and wss at same time that they both communicate or sync data with each other? Or WSS on HTTP and WS on HTTPS?

我的要求是,如果某些用户通过 WS 或 WSS 连接,他们可以与每个 other.Now 通信,如果我 运行 节点服务器 WSS 它不会 运行 over HTTP 并且如果 运行 for WS 那么它在 HTTPS 上无法连接。有什么解决办法吗?

经过长时间的研究,我终于找到了这个解决方案并且对我有用 requiring.This 是我的 sever.js 文件。

/**
Before running:
> npm install ws
Then:
> node server.js
> open http://localhost:8080 in the browser
*/


const http = require('http');
const fs = require('fs');
const ws = new require('ws');

//for wss
const https = require('https');
const options = {
  key: fs.readFileSync('key.pem'),
  cert: fs.readFileSync('cert.pem')
};


const wss = new ws.Server({noServer: true});

const clients = new Set();

function accept(req, res) {
  
  if (req.url == '/ws' && req.headers.upgrade &&
      req.headers.upgrade.toLowerCase() == 'websocket' &&
      // can be Connection: keep-alive, Upgrade
      req.headers.connection.match(/\bupgrade\b/i)) {
    wss.handleUpgrade(req, req.socket, Buffer.alloc(0), onSocketConnect);
  } else if (req.url == '/') { // index.html
    fs.createReadStream('./index.html').pipe(res);
  } else { // page not found
    res.writeHead(404);
    res.end();
  }
}

function onSocketConnect(ws) {
  clients.add(ws);
  log(`new connection`);

  ws.on('message', function(message) {
    log(`message received: ${message}`);

    message = message.slice(0, 500); // max message length will be 50

    for(let client of clients) {
      client.send(message);
    }
  });

  ws.on('close', function() {
    log(`connection closed`);
    clients.delete(ws);
  });
}

let log;
if (!module.parent) {
  log = console.log;

// for wss
  https.createServer(options,accept).listen(8443);

  http.createServer(accept).listen(8080);
} else {
  // to embed into javascript.info
  log = function() {};
  // log = console.log;
  exports.accept = accept;
}

现在 WS 和 WSS links 将 运行 来自相同的 file.For WSS 端口将为 8443,对于 WS 8080,其他 link 将保持不变。 对于 WSS,这些是必需的

键:fs.readFileSync('key.pem'),

证书:fs.readFileSync('cert.pem')

这里是生成这些文件的帮助
