Node.js PeerJS-连接事件'；s参数不是id

在中，连接事件的参数不是id。我猜它是一个套接字

下面是我的代码

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

app.get('/', function(req, res, next) { res.send('Hello world!'); });

var server = app.listen(9000);

var options = {
    debug: true
};

app.use('/api', ExpressPeerServer(server, options));

server.on('connection', function(id) { console.log(id); });

当我运行它并进入时，控制台会打印出巨大的文本，看起来不像id

如何获取香草ID？

您试图使用http模块的连接事件，而不是ExpressPeerServer

下面是修改后的代码

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

app.get('/', function(req, res, next) { res.send('Hello world!'); });

var server = app.listen(9000);

var options = {
    debug: true
};

var peerServer = ExpressPeerServer(server, options);
app.use('/api', peerServer);

peerServer.on('connection', function(id) { console.log(id); });

---

当您输入时，它将打印香草ID。
