PeerJS - 连接事件的参数不是id

Question

在PeerJS Server中，连接事件的参数不是id。我想这是一个插座。

以下是我的代码。

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); });

当我运行它并输入http://localhost:9000/时，控制台会打印大量文本，看起来不像是id。

如何获得香草ID？

Answer 1

您尝试使用http模块的连接事件，而不是ExpressPeerServer。

以下是经过修改的代码。

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http://localhost:9000/时，它会打印香草ID。
