node+socket实现简易聊天室功能

本文实例为大家分享了node+socket实现简易聊天室的具体代码，供大家参考，具体内容如下

服务端

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\")
})

客户端

const net = require(\'net\')
const readline =  require(\'readline\')
//读取输入的信息
const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
});

//名字
const name  =  process.argv[2]
//连接服务器
const client = net.createConnection({port:9527},()=>{
    console.log(name+\'连接到服务器\');
    client.write(`login:${name}`)
    client.name = name
    //开始发送信息
    sendMsg(client)
})

client.on(\'data\', (chunk) => {

    let data  = JSON.parse(chunk.toString())
    if(data){
        console.log(`[${data.name}] : ${data.msg}`)
    }
});
client.on(\'end\', () => {
    console.log(\'已从服务器断开\');
});
client.on(\'error\', () => {
    console.log(\'服务器错误\');
});

//一直递归输出
function sendMsg(client){

    rl.question(\'\',(line)=>{
        client.write(JSON.stringify({
            name:client.name,
            msg:line
        }))
        sendMsg(client)
    })
}
