系统模块的实现
登录模块
微信小程序端登录模块
用户首次进入小程序时，调用wx.login()获取临时登录凭证code，发送至后端/api/auth/wxLogin接口；后端通过微信官方接口换取openid并查询用户是否存在。若为新用户，则自动创建基础账户并返回token；若为老用户，则校验状态并返回完整用户信息。前端将token与用户数据存入本地缓存wx.setStorageSync('userInfo')，后续请求携带token进行身份认证。
后台管理系统登录模块
管理员在登录页面输入账号与密码，点击"登录"按钮后，前端调用loginApi向后端/admin/auth/login发起POST请求。后端验证账号密码及角色权限，成功后生成JWT令牌并返回。前端将token存入Vuex与localStorage，后续所有管理接口请求均在Authorization头中携带该token，未认证或权限不足的请求将被拦截并跳转至登录页。
后台管理系统登录界面
系统用户管理模块
管理员管理
在后台"系统用户管理"页面，管理员可查看所有注册用户列表，筛选角色为"管理员"的账户。通过操作栏的"编辑"按钮，可修改其姓名、手机号或重置密码；点击"禁用"则调用userController.disableAdmin(id)接口，将该账户状态设为无效，使其无法登录后台系统，保障权限安全。
管理员管理界面
普通用户管理
管理员在用户管理界面选择角色为"普通用户"的条目，可执行查看详情、冻结账户或删除操作。当用户存在违规行为时，点击"冻结"按钮触发userController.freezeUser(id)请求，后端更新用户状态字段，前端同步刷新列表。被冻结用户在小程序端登录时将收到"账户已被限制"提示，无法继续使用核心功能。
普通用户管理界面
非遗项目管理模块
微信小程序端非遗项目
用户进入"非遗项目"页面后，小程序向/api/heritage/list接口发起分页请求，获取项目缩略图、名称、类型及简介。点击任一项目卡片，跳转至详情页，加载视频、语音讲解、文化故事等富媒体内容，并显示关联传承人信息。页面底部集成点赞、收藏、分享按钮，用户交互后实时更新状态并同步至服务器。
非遗项目展示界面
非遗项目发布
普通用户在"我的"页面点击"发布非遗项目"，需先完成实名认证。进入表单页后，填写项目名称、类型、来源、详细描述，并上传视频与图片素材。提交时调用/api/heritage/submit接口，数据暂存为"待审核"状态。发布成功后提示"已提交，等待管理员审核"，用户可在"我的发布"中查看审核进度。
非遗项目发布界面
管理员后台非遗项目管理
管理员在"非遗项目管理"界面查看所有待审、已发布及驳回的项目列表。点击"审核"按钮进入详情页，可预览用户提交的全部内容。若信息真实合规，点击"通过"触发heritageController.approve(id)请求，项目状态变更为"已发布"并同步至小程序端；若资料不全或存疑，则点击"驳回"并填写原因，用户将收到通知并可重新编辑提交。
管理员审核非遗项目界面
传承人管理模块
微信小程序端传承人展示
用户在首页或非遗项目详情页点击"传承人"标签，跳转至传承人列表页。每个传承人卡片展示姓名、技艺类别、所在地及头像。点击进入个人主页，可查看详细介绍、代表作品。
传承人展示界面
后台管理员发布传承人
管理员在"传承人管理"页面点击"新增传承人"，填写姓名、所属非遗项目、传承地址、联系电话、技艺特点及个人简介，并上传形象照。提交后调用inheritorController.createInheritor()接口，数据写入数据库并与对应非遗项目建立关联。保存成功后，该传承人信息立即在小程序端同步展示。
发布传承人界面
非遗活动管理模块
微信小程序端非遗活动
非遗活动展示
用户进入"非遗活动"页面，系统调用/api/activity/list获取近期活动列表，按时间倒序排列。每项活动显示标题、类型、时间、地点及封面图。点击进入详情页，可查看完整介绍、参与须知及当前报名人数，页面底部提供"立即报名"按钮，引导用户完成后续流程。
非遗活动展示界面
非遗活动报名
用户在活动详情页点击"立即报名"，若未登录则先触发登录流程。登录后，小程序调用/api/activity/register接口，携带用户ID与活动ID提交报名申请。后端校验活动是否开放、名额是否充足，成功后返回报名编号，前端提示"报名成功，请留意通知"，并在"我的报名"中记录该活动状态。
非遗活动报名界面
后台管理员非遗活动报名管理
管理员在后台"活动报名管理"界面查看待处理的报名记录，列表包含用户昵称、手机号、报名时间及活动名称。点击某条记录可查看详情，确认无误后点击"审核通过"按钮，触发registrationController.approve(id)请求，更新报名状态为"已确认"；若发现信息不符或超额报名，则点击"拒绝"并填写理由，用户端将同步收到审核结果通知。

}**前端：**基于uni-app框架构建跨平台用户界面，使用HTML5、CSS3和JavaScript/Vue.js实现页面结构与交互逻辑，通过uni-app内置路由或Vue Router管理页面导航，Vuex或Pinia维护全局状态。采用uni-ui或uView等组件库快速搭建界面，使用uni.request或Axios（经适配）封装HTTP请求实现与后端的数据通信，同时可调用uni-app提供的丰富原生API（如相机、定位、支付等）增强移动端能力。
**后端：**基于Spring Boot框架搭建，遵循Controller-Service-Mapper三层架构。Controller层接收前端请求并校验参数，Service层处理核心业务逻辑，Mapper层通过MyBatis或MyBatis-Plus完成数据库操作。使用Spring Security或Shiro结合JWT实现用户认证与权限控制。
**数据库：**采用MySQL存储持久化数据，Redis缓存热点信息以提升系统性能。
开发工具： 使用HBuilderX或VSCode开发前端（uni-app），IDEA开发后端，Git进行版本管理，Maven管理后端依赖，npm或yarn管理前端依赖，并通过HBuilderX的App发布功能或命令行工具完成多端（iOS、Android、H5、各小程序）打包发布。
