构建自己peerjs服务器

webrtc的peerjs教程和插件下载

服务器.js

var express = require('express');
var app = express();
// create express peer server
var ExpressPeerServer = require('peer').ExpressPeerServer;

var options = {
    debug: true
}

// create a http server instance to listen to request
var server = require('http').createServer(app);

// peerjs is the path that the peerjs server will be connected to.
const peerServer = ExpressPeerServer(server, options);
app.use('/peerjs', peerServer);
// Now listen to your ip and port.
server.listen(443, "192.168.2.18");

peerServer.on('connection', (client) => { 
  console.log('connection:'+client.getId());
});
peerServer.on('disconnect', (client) => { 
  console.log('disconnect:'+client.getId());
});

终端JS

function initialize() {
    peer = new Peer({
        host: '192.168.2.18',
        port: 443,
        path: '/peerjs',

                username: 'user1'
            },
            ]
        },
    
        debug: 3
    });
    peer.on('open', function (id) {
        // Workaround for peer.reconnect deleting previous id
        if (peer.id === null) {
            console.log('Received null id from peer open');
            peer.id = lastPeerId;
        } else {
            lastPeerId = peer.id;
        }

        console.log('ID: ' + peer.id);
    });
    
    peer.on('connection', function (c) {
        // Disallow incoming connections
        c.on('open', function() {
            c.send("Sender does not accept incoming connections");
            setTimeout(function() { c.close(); }, 500);
        });
    });
    peer.on('disconnected', function () {
        status.innerHTML = "Connection lost. Please reconnect";
        console.log('Connection lost. Please reconnect');

        // Workaround for peer.reconnect deleting previous id
        peer.id = lastPeerId;
        peer._lastServerId = lastPeerId;
        peer.reconnect();
    });
    peer.on('close', function() {
        conn = null;
        status.innerHTML = "Connection destroyed. Please refresh";
        console.log('Connection destroyed');
    });
    peer.on('error', function (err) {
        console.log(err);
        alert('' + err);
    });
};
