JAVA红娘交友小程序实现原理及开源uniapp代码片段

JAVA红娘交友小程序实现原理后端架构设计基于Spring Boot框架搭建RESTful API服务采用Maven进行依赖管理。核心模块包括用户认证模块、匹配算法模块、即时通讯模块和数据持久化模块。数据库设计使用MySQL关系型数据库主要表结构包括用户表user_profile存储用户基本信息、择偶条件匹配记录表match_record记录用户间的匹配状态消息表chat_message存储用户间聊天记录匹配算法实现采用基于标签的协同过滤算法核心公式为 $similarity \frac{\sum_{i1}^{n}(A_i \times B_i)}{\sqrt{\sum_{i1}^{n}A_i^2} \times \sqrt{\sum_{i1}^{n}B_i^2}}$算法流程用户画像构建通过问卷调查收集用户兴趣标签特征向量化将文字标签转换为数值向量相似度计算使用余弦相似度计算用户匹配度推荐排序按匹配分数降序排列推荐列表即时通讯方案集成WebSocket协议实现实时通讯消息格式采用JSON规范{ senderId: U1001, receiverId: U1002, content: 你好认识一下, timestamp: 1625097600000 }安全机制JWT身份验证基于HS256算法的token签发敏感数据加密使用AES-256对联系方式等字段加密内容审核接入第三方文本/图片审核APIUniapp前端实现代码片段用户注册页面template view classcontainer u-form :modelform refuForm u-form-item label手机号 propphone u-input v-modelform.phone placeholder请输入手机号/ /u-form-item u-form-item label密码 proppassword u-input v-modelform.password password placeholder请输入密码/ /u-form-item u-button clicksubmit立即注册/u-button /u-form /view /template script export default { data() { return { form: { phone: , password: }, rules: { phone: [ { required: true, message: 请输入手机号, trigger: blur }, { pattern: /^1[3-9]\d{9}$/, message: 手机号格式错误 } ], password: [ { required: true, message: 请输入密码, trigger: blur }, { min: 6, max: 20, message: 密码长度6-20位 } ] } } }, methods: { async submit() { try { const res await this.$http.post(/api/register, this.form) uni.showToast({ title: 注册成功 }) uni.navigateTo({ url: /pages/login/login }) } catch (e) { uni.showToast({ title: e.message, icon: none }) } } } } /script匹配推荐组件template view swiper circular :indicator-dotstrue swiper-item v-for(item,index) in list :keyindex image :srcitem.avatar modeaspectFill/ view classinfo text{{item.nickname}} · {{item.age}}岁/text text{{item.city}} · {{item.job}}/text /view /swiper-item /swiper view classactions u-icon nameclose clickdislike/u-icon u-icon nameheart clicklike/u-icon /view /view /template script export default { data() { return { list: [] } }, mounted() { this.loadRecommend() }, methods: { async loadRecommend() { this.list await this.$http.get(/api/recommend) }, async like(id) { await this.$http.post(/api/like, { targetId: id }) uni.showToast({ title: 喜欢成功 }) }, async dislike(id) { await this.$http.post(/api/dislike, { targetId: id }) uni.showToast({ title: 已跳过 }) } } } /script即时通讯页面template view classchat-container scroll-view scroll-y classmessage-list view v-for(msg,index) in messages :keyindex :class[message, msg.sender user.id ?
