-本目录包含了应用的所有业务逻辑服务层,负责处理业务规则、数据验证和错误处理。 - -## 服务列表 - -### 1. UserService - 用户服务 -处理用户相关的所有业务逻辑,包括用户注册、登录、密码管理等。 - -**主要功能:** -- 用户注册和登录 -- 用户信息管理(增删改查) -- 密码加密和验证 -- 用户统计和搜索 -- 批量操作支持 - -**使用示例:** -```javascript -import { userService } from '../services/index.js' - -// 用户注册 -const newUser = await userService.register({ - username: 'testuser', - email: 'test@example.com', - password: 'password123' -}) - -// 用户登录 -const loginResult = await userService.login({ - username: 'testuser', - password: 'password123' -}) -``` - -### 2. ArticleService - 文章服务 -处理文章相关的所有业务逻辑,包括文章的发布、编辑、搜索等。 - -**主要功能:** -- 文章的增删改查 -- 文章状态管理(草稿/发布) -- 文章搜索和分类 -- 阅读量统计 -- 相关文章推荐 -- 分页支持 - -**使用示例:** -```javascript -import { articleService } from '../services/index.js' - -// 创建文章 -const article = await articleService.createArticle({ - title: '测试文章', - content: '文章内容...', - category: '技术', - tags: 'JavaScript,Node.js' -}) - -// 获取已发布文章 -const publishedArticles = await articleService.getPublishedArticles() - -// 搜索文章 -const searchResults = await articleService.searchArticles('JavaScript') -``` - -### 3. BookmarkService - 书签服务 -处理用户书签的管理,包括添加、编辑、删除和搜索书签。 - -**主要功能:** -- 书签的增删改查 -- URL格式验证 -- 批量操作支持 -- 书签统计和搜索 -- 分页支持 - -**使用示例:** -```javascript -import { bookmarkService } from '../services/index.js' - -// 添加书签 -const bookmark = await bookmarkService.createBookmark({ - user_id: 1, - title: 'Google', - url: 'https://www.google.com', - description: '搜索引擎' -}) - -// 获取用户书签 -const userBookmarks = await bookmarkService.getUserBookmarks(1) - -// 搜索书签 -const searchResults = await bookmarkService.searchUserBookmarks(1, 'Google') -``` - -### 4. SiteConfigService - 站点配置服务 -管理站点的各种配置信息,如站点名称、描述、主题等。 - -**主要功能:** -- 配置的增删改查 -- 配置值验证 -- 批量操作支持 -- 默认配置初始化 -- 配置统计和搜索 - -**使用示例:** -```javascript -import { siteConfigService } from '../services/index.js' - -// 获取配置 -const siteName = await siteConfigService.get('site_name') - -// 设置配置 -await siteConfigService.set('site_name', '我的新网站') - -// 批量设置配置 -await siteConfigService.setMany({ - 'site_description': '网站描述', - 'posts_per_page': 20 -}) - -// 初始化默认配置 -await siteConfigService.initializeDefaultConfigs() -``` - -### 5. JobService - 任务服务 -处理后台任务和定时任务的管理。 - -**主要功能:** -- 任务调度和管理 -- 任务状态监控 -- 任务日志记录 - -## 错误处理 - -所有服务都使用统一的错误处理机制: - -```javascript -import CommonError from 'utils/error/CommonError.js' - -try { - const result = await userService.getUserById(1) -} catch (error) { - if (error instanceof CommonError) { - // 业务逻辑错误 - console.error(error.message) - } else { - // 系统错误 - console.error('系统错误:', error.message) - } -} -``` - -## 数据验证 - -服务层负责数据验证,确保数据的完整性和正确性: - -- **输入验证**:检查必填字段、格式验证等 -- **业务验证**:检查业务规则,如用户名唯一性 -- **权限验证**:确保用户只能操作自己的数据 - -## 事务支持 - -对于涉及多个数据库操作的方法,服务层支持事务处理: - -```javascript -// 在需要事务的方法中使用 -async createUserWithProfile(userData, profileData) { - // 这里可以添加事务支持 - const user = await this.createUser(userData) - // 创建用户档案... - return user -} -``` - -## 缓存策略 - -服务层可以集成缓存机制来提高性能: - -```javascript -// 示例:缓存用户信息 -async getUserById(id) { - const cacheKey = `user:${id}` - let user = await cache.get(cacheKey) - - if (!user) { - user = await UserModel.findById(id) - await cache.set(cacheKey, user, 3600) // 缓存1小时 - } - - return user -} -``` - -## 使用建议 - -1. **控制器层调用服务**:控制器应该调用服务层方法,而不是直接操作模型 -2. **错误处理**:在控制器中捕获服务层抛出的错误并返回适当的HTTP响应 -3. **数据转换**:服务层负责数据格式转换,控制器负责HTTP响应格式 -4. **业务逻辑**:复杂的业务逻辑应该放在服务层,保持控制器的简洁性 - -## 扩展指南 - -添加新的服务: - -1. 创建新的服务文件(如 `NewService.js`) -2. 继承或实现基础服务接口 -3. 在 `index.js` 中导出新服务 -4. 添加相应的测试用例 -5. 更新文档 - -```javascript -// 新服务示例 -class NewService { - async doSomething(data) { - try { -
