How to use the Layui framework to develop a question consultation platform that supports instant Q&A and knowledge sharing

Introduction:
With the rapid development of the Internet, people's needs have also increasingly diverse. In the field of question answering and knowledge sharing, a convenient and efficient platform can meet the needs of users and help improve the quality of question answering. This article will introduce how to use the Layui framework to develop a question consultation platform that supports instant Q&A and knowledge sharing, and provide specific code examples.

1. System architecture design

Front-end framework selection
Layui is a simple, easy-to-use, highly compatible UI framework with rich components and styles, which is very suitable for development The front-end page of the problem consultation platform. We can use Layui to build user interfaces and provide good interactive experience and visual effects.
Back-end technology selection
In terms of back-end development, you can choose to use Node.js as the server-side language and cooperate with the Express framework to build a web application based on the MVC design pattern. This enables asynchronous, efficient event-driven programming and improves system performance and response speed.
Database Selection
We can use the relational database MySQL to store related data such as user information, questions, answers and knowledge content. MySQL is a mature and stable database system with high reliability and high performance.
Instant messaging technology selection
In order to realize the instant question and answer function, you can choose to use WebSocket technology. WebSocket is a full-duplex communication protocol that enables real-time data transmission between the server and the client.

2. Function module design

User management module
Includes user registration, login, personal information modification and other functions. Users can obtain an independent identity by registering an account, and use the account to log in to the system, post questions in the system, answer questions from other users, etc.
Problem Management Module
Users can raise questions in the system, classify them, add labels, etc. Other users can browse the question list, search for questions of interest, and answer and comment on the questions.
Knowledge Sharing Module
Users can share their knowledge, experience and opinions in the system. Other users can browse the knowledge list, like, collect, comment, etc.
Instant Q&A module
Questioners can immediately send questions to online users and receive real-time answers to the questions. Respondents can receive live Q&A requests and answer them.

3. Code Implementation Example
The following is a sample code built using the Layui framework and Node.js. The specific code details can be adjusted and improved according to actual project needs.

Front-end page example

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>问题咨询平台</title>
  <link rel="stylesheet" href="layui/css/layui.css">
</head>
<body>
<!-- 主体内容 -->
<div class="container">
  <div class="layui-row">
 <div class="layui-col-md6">
   <!-- 问题列表 -->
   <div class="layui-card">
     <div class="layui-card-header">问题列表</div>
     <div class="layui-card-body">
       <table class="layui-table">
         <thead>
           <tr>
             <th>问题标题</th>
             <th>提问者</th>
             <th>回答数</th>
           </tr> 
         </thead>
         <tbody>
           <!-- 列表数据 -->
         </tbody>
       </table>
     </div>
   </div>
 </div>
 <div class="layui-col-md6">
   <!-- 问题详情 -->
   <div class="layui-card">
     <div class="layui-card-header">问题详情</div>
     <div class="layui-card-body">
       <!-- 详情内容 -->
     </div>
   </div>
 </div>
  </div>
</div>
<!-- 引入layui -->
<script src="layui/layui.js" charset="utf-8"></script>
<!-- 页面逻辑 -->
<script>
layui.use(['table', 'laytpl'], function(){
  var table = layui.table;
  var laytpl = layui.laytpl;
  
  // 使用table组件渲染问题列表
  table.render({
 elem: '.layui-table',
 url: '/api/question/list',
 cols: [[
   {field:'title', title: '问题标题'},
   {field:'author', title: '提问者'},
   {field:'answers', title: '回答数'}
 ]]
  });
  
  // 问题列表点击事件
  table.on('row', function(obj){
 var data = obj.data;
 // 使用laytpl渲染问题详情
 var getTpl = document.getElementById('detailTpl').innerHTML;
 laytpl(getTpl).render(data, function(html){
   $('.layui-card-body').html(html);
 });
  });
});
</script>
</body>
</html>

Backend API example (using Express framework)

const express = require('express');
const app = express();

// 获取问题列表
app.get('/api/question/list', (req, res) => {
  // 获取问题数据
  const questionList = [
 {title: '问题1', author: '用户1', answers: 10},
 {title: '问题2', author: '用户2', answers: 5},
 // ...
  ];
  res.json(questionList);
});

app.listen(3000, () => {
  console.log('服务器已启动');
});
