node+socket实现简易聊天室功能

const net = require('net')const  server = net.createServer()//用户列表let clients = []//监听连接server.on('connection',client=>{    client.on('data',(chunk)=>{        let data  = chunk.toString()        if(data.match(/login:(.*)/)){            let name = data.match(/login:(.*)/)[1]            client.name = name            clients.push(client)            console.log(`用户${name}上线`)        }else{            for (const client of clients) {                if(client.name!==JSON.parse(data).name){                    client.write(data)                }            }        }    })    client.on('close',()=>{        console.log(`用户${client.name}下线`)    })    client.on('error',()=>{        console.log(`用户${client.name}发生错误`)    })})server.on('error',(err)=>{    console.log('服务器错误',err)})server.on('close',()=>{    console.log('服务器关闭')})server.listen(9527,()=>{    console.log("服务器开启")})
