要修改url路径的文件： 1.html/login.html 48行 2.js/wsServer.js 6行 3.js/ws.js 第2行 和 第11行 4.js/app.js 14行(可以不修改)

const WebSocket = require('ws');
const validator = require('validator');//判断json

const server = new WebSocket.Server({
    port: 8888,
    host: '10.31.161.80'
}); // 创建ws服务

let users = {};

server.on('connection', client => {

    let LTSusername = '';
    let LTSpassword = '';
    client.on('message', msg => {

        if (validator.isJSON(msg)) {
            LTSusername = JSON.parse(msg).LTSusername;
            LTSpassword = JSON.parse(msg).LTSpassword;
            users[LTSusername] = client;
            broadcast(msg, client, LTSusername);
        } else {
            broadcast(msg, client, LTSusername);
        }


    });
});


function broadcast(msg, client, LTSusername) {
    if (validator.isJSON(msg)) {
        for (let key in users) {
            users[key].send(`${LTSusername}已上线`);
        }
    } else {
        for (let key in users) {
            let content = msg.replace(/\n/g,"");//msg自动带了一个换行
            users[key].send(`{"msg":"${content}","username":"${LTSusername}"}`);
        }
    }

}
