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?

问题

My requirement is this that if some users connect through WS or WSS they can communicate with each other.Now if i run node server for WSS it does not run over HTTP and if run for WS then it does not Connect on HTTPS .Any solution?

回答1:

After a long research at last i find this solution and is working for me as i was requiring.This is my sever.js file.

/**
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;
}

Now WS and WSS links will run from same file.For WSS port will be 8443 and for WS 8080,Other link will remain same. For WSS these are required

key: fs.readFileSync('key.pem'),

cert: fs.readFileSync('cert.pem')

and here is help for generating these files

//how-to-get-pem-file-from-key-and-crt-files

How to get .pem file from .key and .crt files?

openssl rsa -inform DER -outform PEM -in server.key -out server.crt.pem

Let me know if facing any issue.
