~/styles/variables.scss; } } } }2.2 后端服务设计基于Express的RESTful API设计const express require(express) const mongoose require(mongoose) const cors require(cors) const app express() // 中间件 app.use(cors()) app.use(express.json()) // 数据库连接 mongoose.connect(mongodb://localhost:27017/house-rental, { useNewUrlParser: true, useUnifiedTopology: true }) // 路由定义 app.use(/api/houses, require(./routes/houses)) app.use(/api/users, require(./routes/users)) // 错误处理 app.use((err, req, res, next) { console.error(err.stack) res.status(500).send(Server Error) }) const PORT process.env.PORT || 3000 app.listen(PORT, () console.log(Server running on port ${PORT}))3. 核心功能实现3.1 房源管理模块数据库模型设计Mongoose Schemaconst houseSchema new mongoose.Schema({ title: { type: String, required: true }, price: { type: Number, required: true }, area: { type: Number, required: true }, address: { province: String, city: String, district: String, detail: String }, facilities: [{ name: String, has: Boolean }], images: [String], publishDate: { type: Date, default: Date.now }, landlord: { type: mongoose.Schema.Types.ObjectId, ref: User } }) module.exports mongoose.model(House, houseSchema)前端表单组件关键代码template el-form :modelhouseForm :rulesrules refform el-form-item label房源标题 proptitle el-input v-modelhouseForm.title/el-input /el-form-item el-form-item label租金(元/月) propprice el-input-number v-modelhouseForm.price :min0/el-input-number /el-form-item el-form-item label面积(㎡) proparea el-input-number v-modelhouseForm.area :min0/el-input-number /el-form-item !-- 更多表单项... -- /el-form /template script export default { data() { return { houseForm: { title: , price: 0, area: 0, // 其他字段... }, rules: { title: [{ required: true, message: 请输入标题, trigger: blur }], // 其他验证规则... } } } } /script3.2 搜索与筛选功能Elasticsearch集成方案安装elasticsearch包npm install elastic/elasticsearch创建搜索服务const { Client } require(elastic/elasticsearch) const client new Client({ node: http://localhost:9200 }) async function searchHouses(query) { const { body } await client.search({ index: houses, body: { query: { bool: { must: [ { match: { title: query.keyword }}, { range: { price: { gte: query.minPrice || 0, lte: query.maxPrice || Number.MAX_SAFE_INTEGER } }} ] } } } }) return body.hits.hits.map(hit hit._source) }前端筛选组件实现template div classfilter-container el-input placeholder关键词 v-modelfilters.keyword/el-input el-slider v-modelpriceRange range :max10000 :step100 /el-slider el-checkbox-group v-modelfilters.facilities el-checkbox v-foritem in facilityOptions :keyitem.value :labelitem.value {{ item.label }} /el-checkbox /el-checkbox-group /div /template4. 高级功能实现4.1 地图集成高德地图接入步骤申请开发者Key安装AMap插件npm install amap/amap-jsapi-loader --save组件封装template div idmap-container/div /template script import AMapLoader from amap/amap-jsapi-loader export default { data() { return { map: null, markers: [] } }, mounted() { this.initMap() }, methods: { async initMap() { try { const AMap await AMapLoader.load({ key: your-amap-key, version: 2.0, plugins: [AMap.MarkerClusterer] }) this.map new AMap.Map(map-container, { zoom: 12, center: [116.397428, 39.90923] }) this.addMarkers(this.houses) } catch (error) { console.error(地图加载失败:, error) } }, addMarkers(houses) { // 清除旧标记 this.markers.forEach(marker marker.setMap(null)) this.markers [] // 添加新标记 houses.forEach(house { const marker new AMap.Marker({ position: new AMap.LngLat(house.longitude, house.latitude), title: house.title }) marker.setMap(this.map) this.markers.push(marker) }) } } } /script4.2 即时通讯功能基于Socket.IO的实现服务端设置const http require(http) const socketIO require(socket.io) const server http.createServer(app) const io socketIO(server, { cors: { origin: http://localhost:8080, methods: [GET, POST] } }) io.on(connection, socket { console.log(新用户连接) socket.on(join_room, roomId { socket.join(roomId) }) socket.on(send_message, ({ roomId, message }) { io.to(roomId).emit(receive_message, message) }) socket.on(disconnect, () { console.log(用户断开连接) }) })前端封装// src/utils/socket.js import io from socket.io-client let socket null export function connectSocket(token) { socket io(http://localhost:3000, { auth: { token } }) return socket } export function joinRoom(roomId) { if (socket) socket.emit(join_room, roomId) } export function sendMessage(roomId, message) { if (socket) socket.emit(send_message, { roomId, message }) } export function onMessageReceived(callback) { if (socket) socket.on(receive_message, callback) }5. 性能优化实践5.1 前端性能提升路由懒加载配置const routes [ { path: /, component: () import(/views/Home.vue) }, { path: /list, component: () import(/views/List.vue) } ]图片懒加载指令// main.js Vue.directive(lazy, { inserted(el, binding) { const observer new IntersectionObserver((entries) { entries.forEach(entry { if (entry.isIntersecting) { el.src binding.value observer.unobserve(el) } }) }) observer.observe(el) } })使用示例img v-lazyhouse.image alt房源图片5.2 后端性能优化数据库查询优化// 使用populate关联查询 House.find() .populate(landlord, name avatar) .lean() // 转换为普通JS对象 .exec() // 添加索引 houseSchema.index({ title: text, address.city: 1 })Redis缓存实现const redis require(redis) const client redis.createClient() async function getHousesWithCache() { const cacheKey houses:all return new Promise((resolve, reject) { client.get(cacheKey, async (err, data) { if (data) return resolve(JSON.parse(data)) const houses await House.find().lean() client.setex(cacheKey, 3600, JSON.stringify(houses)) resolve(houses) }) }) }6. 安全防护措施6.1 常见攻击防护XSS防护// 使用helmet中间件 app.use(helmet()) // 前端输入过滤 function sanitizeInput(input) { return input.replace(/[^]*?/gm, ) }CSRF防护// 使用csurf中间件 const csrf require(csurf) app.use(csrf({ cookie: true })) // 前端获取token axios.interceptors.request.use(config { if (csrfToken) { config.headers[X-CSRF-Token] csrfToken } return config })SQL注入防护// 使用参数化查询 House.find({ title: { $regex: new RegExp(keyword, i) } })6.2 认证与授权JWT认证实现const jwt require(jsonwebtoken) // 生成token function generateToken(user) { return jwt.sign( { id: user._id, role: user.role }, process.env.JWT_SECRET, { expiresIn: 7d } ) } // 验证中间件 function authMiddleware(req, res, next) { const token req.header(Authorization)?.replace(Bearer , ) if (!token) return res.status(401).send(Access denied) try { const decoded jwt.verify(token, process.env.JWT_SECRET) req.user decoded next() } catch (err) { res.status(400).send(Invalid token) } }RBAC权限控制// 角色定义 const ROLES { ADMIN: admin, LANDLORD: landlord, TENANT: tenant } // 权限中间件 function checkRole(requiredRole) { return (req, res, next) { if (req.user.role ! requiredRole) { return res.status(403).send(Forbidden) } next() } } // 路由使用示例 router.post(/houses, authMiddleware, checkRole(ROLES.LANDLORD), createHouse )7. 部署与监控7.1
