我正在寻找一种实现聊天功能的方法，
我正在为残障人士建立一个约会/友谊网站，它很顺利。
因为我是编程领域的初学者，所以我一直在寻找一种方法来创建一个简单的聊天功能（理想情况下只有在相互喜欢或感兴趣时才能运行），所以我在youtube上发现了一个 - [ https://www.youtube.com/watch?v=tHbCkikFfDE]，完美，无页面重装等。
当它在Localhost：3000上打开时它就像一个魅力，但是我尝试将它实现到我的网站并显示，但不起作用，此聊天也有登录功能，但考虑到当客户端在我的网站上他们已经登录。我想知道如何获取我的用户数据，然后将其用于聊天。

原谅长篇文章，我将继续在互联网上寻找答案，所以也许我可以使这个问题更具体。提前谢谢。
答案 0 :(得分：0)
我会告诉你mysql变种它非常相似。
首先，您需要一些额外的模块来完成这项工作：
var CONFIG = require('./config');
var dl = require('delivery');
var fs = require("fs");
var mysql = require('mysql');
var express = require("express");
var app = express();
var http = require('http');
var https = require('https');
var mkdirp = require('mkdirp');
var nodemailer = require('nodemailer');
function include(f) {eval.apply(global, [read(f)]);}
function read(f) {return fs.readFileSync(f).toString();}
从npm安装定义中的所有模块。
var REG_PATH = CONFIG.PATH_OF_WWW + CONFIG.REG_PATH;
include('lib/preinit.js');
var DATABASE = require('./account/account');
DATABASE.fs = fs;
DATABASE.handleDisconnect();
DATABASE.GET_ALL_USERS();
// NO SECURE - HTTP
var server = http.createServer(app);
var io = require('socket.io').listen(server);
server.listen(CONFIG.ACCOUNT_PORT);
console.log('Socket server listening on port : ' , CONFIG.ACCOUNT_PORT);
接下来是套接字作业，但您可以在address找到完整的文件。
我会展示您的小型自定义模块（需要（＆＃39; ./ account / account＆＃39;））：
