🗣 Wd提问: 域名出售系统

🤖 Ai回答:
我来为您设计一个域名出售系统的完整解决方案。

系统架构设计

1、技术栈选择
javascript
// 前端技术栈
React/Vue.js (前端框架)
Tailwind CSS/Bootstrap (UI框架)
Axios (HTTP请求)

// 后端技术栈
Node.js + Express (后端框架)
MongoDB/Mysql (数据库)
Redis (缓存)
Socket.IO (实时通信)

// 部署方案
Nginx (反向代理)
Docker (容器化)
PM2 (进程管理)

2、核心功能模块

用户管理系统
javascript
// 用户模型
const UserSchema = {
username: String,
email: String,
password: String,
role: { type: String, enum: ['user', 'admin', 'seller'] },
profile: {
avatar: String,
bio: String,
phone: String
},
createdAt: Date,
updatedAt: Date
}

// 认证系统
class AuthService {
async register(userData) {
// 用户注册逻辑
}

async login(email, password) {
// 用户登录逻辑
}

async verifyToken(token) {
// Token验证
}
}

域名管理系统
javascript
// 域名模型
const DomainSchema = {
name: String,
tld: String,
price: Number,
status: {
type: String,
enum: ['available', 'listed', 'sold', 'pending']
},
seller: ObjectId,
buyer: ObjectId,
category: String,
description: String,
tags: [String],
createdAt: Date,
updatedAt: Date,
expirationDate: Date
}

// 域名搜索和筛选
class DomainService {
async searchDomains(filters) {
const query = {}

if (filters.search) {
query.$or = [
{ name: { $regex: filters.search, $options: 'i' } },
{ description: { $regex: filters.search, $options: 'i' } }
]
}

if (filters.category) {
query.category = filters.category
}

if (filters.minPrice) {
query.price = { $gte: filters.minPrice }
}

return await Domain.find(query).sort({ createdAt: -1 })
}
}

购买交易系统
javascript
// 交易模型
const TransactionSchema = {
domain: ObjectId,
buyer: ObjectId,
seller: ObjectId,
amount: Number,
status: {
type: String,
enum: ['pending', 'confirmed', 'completed', 'cancelled']
},
paymentMethod: String,
transactionId: String,
createdAt: Date,
completedAt: Date
}

// 支付处理
class PaymentService {
async processPayment(transactionData) {
try {
// 创建支付订单
const payment = await this.createPaymentOrder(transactionData)

// 调用第三方支付API
const paymentResult = await this.processWithGateway(payment)

// 更新交易状态
await this.updateTransactionStatus(payment.transactionId, 'confirmed')

return paymentResult
} catch (error) {
throw new Error('支付失败: ' + error.message)
}
}
}

3、前端页面设计

主页展示
jsx
// HomePage.jsx
import React, { useState, useEffect } from 'react'

const HomePage = () = {
const [domains, setDomains] = useState([])
const [searchTerm, setSearchTerm] = useState('')
const [category, setCategory] = useState('all')

useEffect(() = {
fetchDomains()
}, [searchTerm, category])

const fetchDomains = async () = {
const response = await fetch('/api/domains?search=' + searchTerm + '&category=' + category)
const data = await response.json()
setDomains(data)
}

return (
<div className=container mx-auto px-4
{/* 搜索区域 */}
<div className=mb-8
<input
type=text
placeholder=搜索域名...
value={searchTerm}
onChange={(e) = setSearchTerm(e.target.value)}
className=w-full p-3 border rounded-lg
/
</div

{/* 域名列表 */}
<div className=grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6
{domains.map(domain = (
<DomainCard key={domain._id} domain={domain} /
))}
</div
</div
)
}

域名详情页
jsx
// DomainDetail.jsx
const DomainDetail = ({ domain }) = {
const [isBidding, setIsBidding] = useState(false)
const [bidAmount, setBidAmount] = useState('')

const handleBid = async () = {
const response = await fetch('/api/bids', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
domainId: domain._id,
amount: bidAmount
})
})

if (response.ok) {
alert('出价成功！')
setIsBidding(false)
}
}

return (
<div className=max-w-4xl mx-auto
<div className=bg-white rounded-lg shadow-md p-6
<h1 className=text-3xl font-bold mb-4{domain.name}.{domain.tld}</h1

<div className=flex items-center justify-between mb-6
<span className=text-2xl font-bold text-green-600
¥{domain.price.toLocaleString()}
</span
<button className=bg-blue-600 text-white px-6 py-2 rounded-lg hover:bg-blue-700
立即购买
</button
</div

<div className=grid grid-cols-2 gap-4 mb-6
<div
<h3 className=font-semibold分类</h3
<p{domain.category}</p
</div
<div
<h3 className=font-semibold状态</h3
<p{domain.status}</p
</div
</div

<div className=mb-6
<h3 className=font-semibold mb-2描述</h3
<p{domain.description}</p
</div

<div className=border-t pt-4
<h3 className=font-semibold mb-2标签</h3
<div className=flex flex-wrap gap-2
{domain.tags?.map(tag = (
<span key={tag} className=bg-gray-200 px-3 py-1 rounded-full text-sm
{tag}
</span
))}
</div
</div
</div
</div
)
}

4、后端API设计

RESTful API路由
javascript
// routes/domains.js
const express = require('express')
const router = express.Router()

// 获取域名列表
router.get('/', domainController.listDomains)

// 获取单个域名详情
router.get('/:id', domainController.getDomain)

// 创建新域名
router.post('/', authMiddleware, domainController.createDomain)

// 更新域名信息
router.put('/:id', authMiddleware, domainController.updateDomain)

// 删除域名
router.delete('/:id', authMiddleware, domainController.deleteDomain)

module.exports = router

数据库连接配置
javascript
// config/database.js
const mongoose = require('mongoose')

const connectDB = async () = {
try {
await mongoose.connect(process.env.MONGODB_URI, {
useNewUrlParser: true,
useUnifiedTopology: true,
})
console.log('MongoDB connected successfully')
} catch (error) {
console.error('Database connection error:', error)
process.exit(1)
}
}

module.exports = connectDB

5、安全特性

JWT认证中间件
javascript
// middleware/auth.js
const jwt = require('jsonwebtoken')

const authMiddleware = (req, res, next) = {
const token = req.header('Authorization')?.replace('Bearer ', '')

if (!token) {
return res.status(401).json({ message: '访问令牌缺失' })
}

try {
const decoded = jwt.verify(token, process.env.JWT_SECRET)
req.user = decoded
next()
} catch (error) {
res.status(401).json({ message: '无效的访问令牌' })
}
}

module.exports = authMiddleware

输入验证
javascript
// middleware/validation.js
const validateDomain = (req, res, next) = {
const { name, price, category } = req.body

if (!name !price !category) {
return res.status(400).json({
message: '缺少必要字段: name, price, category'
})
}

if (price <= 0) {
return res.status(400).json({
message: '价格必须大于0'
})
}

next()
