Websocket 失败：帧头无效

发布于 2025-01-20 06:41:48 字数 8420 浏览 0 评论 0原文

I'm using socket.io with peerjs to create a video conference app it shows me this error in the console of browser :

http://localhost:3000/socket.io/?EIO=3&transport=polling&t=O0Hrv -4＆amp; sid = 2C_B3ACCFINUUUFNAAAAA 400（不良请求） 和 WebSocket connection to 'ws://localhost:3000/socket.io/?EIO=3&transport=websocket&sid=TIij4-ksOm6WI8URAAAA' failed: Invalid frame header

Can anyone please help? 我很快就会结束 ＃server.js＃

const express = require('express');
const app = express();
const server = require('http').Server(app);
const { v4: uuidv4 } = require('uuid');
const io = require('socket.io')(server);
const { ExpressPeerServer } = require('peer');
const peerServer = ExpressPeerServer(server, {
    debug: true
});
app.use(express.static('public'));
app.use('/peerjs', peerServer);
app.set('view engine', 'ejs');
app.get('/', (req, res) => {
    res.redirect(`/${uuidv4()}`);
});
app.get('/:room', (req, res) => {
    res.render('room', { roomId: req.param.room })
});
io.on('connection', socket => {
    socket.on('join-room', (roomId, userId) => {
        socket.join(roomId);
        socket.to(roomId).broadcast.emit('user-connected', userId);
        socket.on('message', message => {
            io.to(roomId).emit('createMessage', message)
        })
    })
})
server.listen(process.env.PORT || 3000)
