🌟 一、为什么需要Mock数据？

开发痛点

• 前后端进度不匹配：前端等接口，后端等需求
• 接口频繁变更：影响开发进度
• 测试数据单一：难以覆盖边界情况
• 网络环境依赖：离线无法开发

Mock数据带来的价值

// 传统开发 vs Mock开发对比
传统开发流程：
需求 → 等接口文档 → 等后端接口 → 联调 → 测试

Mock开发流程：
需求 → 定义接口规范 → Mock数据 → 并行开发 → 无缝切换真实接口

🛠️ 二、Mock.js核心概念

2.1 基本语法

import Mock from 'mockjs'

// 1. 基础数据类型生成
Mock.mock({
  // 随机字符串
  'name|1-10': '★',      // 生成1-10个星号
  'title': '@ctitle(5,10)', // 5-10个汉字
  
  // 随机数字
  'age|18-60': 1,        // 18-60之间的整数
  'score|1-100.2': 1,    // 1-100，保留2位小数
  
  // 随机选择
  'status|1': ['成功', '失败', '进行中'],
  'gender|1': ['男', '女'],
  
  // 占位符
  'email': '@email',
  'date': '@date("yyyy-MM-dd")',
  'image': '@image("200x100", "#4A7BF7", "Mock")',
  'color': '@color',
  'province': '@province',
  'city': '@city(true)', // 带省份
  'url': '@url',
  'ip': '@ip'
})

// 2. 生成数组
Mock.mock({
  'list|5-10': [{  // 生成5-10条数据
    'id|+1': 1,     // 自增ID
    'name': '@cname',
    'age|20-40': 1,
    'email': '@email',
    'address': '@county(true)'
  }]
})

2.2 数据模板定义规则

// 规则：'name|rule': value
const dataTemplate = {
  // 1. 属性值是字符串
  'string|1-10': '☆',      // 重复1-10次
  'string|3': 'fixed',     // 固定重复3次
  
  // 2. 属性值是数字
  'number|+1': 1,          // 自增
  'number|1-100': 1,       // 1-100随机
  'number|1-100.2-4': 1,   // 1-100随机，小数部分2-4位
  
  // 3. 属性值是布尔值
  'boolean|1': true,       // 50%概率为true
  'boolean|1-9': true,     // 1/10概率为true
  
  // 4. 属性值是对象
  'object|2': {            // 随机选取2个属性
    'name': '@cname',
    'age': '@integer(20,60)',
    'gender': '@pick(["男","女"])',
    'email': '@email'
  },
  
  // 5. 属性值是数组
  'array|1': ['A', 'B', 'C'],   // 随机选取1个
  'array|1-3': ['A', 'B', 'C'], // 重复1-3次
  'array|2': ['A', 'B', 'C'],   // 重复2次
}

🚀 三、项目集成方案

3.1 方案一：独立Mock服务（推荐）

// mock/index.js - Mock服务入口文件
import Mock from 'mockjs'
import user from './modules/user'
import order from './modules/order'
import product from './modules/product'

// 是否启用Mock（可通过环境变量控制）
const isMockEnabled = process.env.VUE_APP_MOCK === 'true'

if (isMockEnabled) {
  // 用户相关接口
  Mock.mock('/api/user/login', 'post', user.login)
  Mock.mock('/api/user/info', 'get', user.getUserInfo)
  Mock.mock('/api/user/list', 'get', user.getUserList)
  
  // 订单相关接口
  Mock.mock('/api/order/list', 'get', order.getOrderList)
  Mock.mock('/api/order/detail', 'get', order.getOrderDetail)
  Mock.mock('/api/order/create', 'post', order.createOrder)
  
  // 商品相关接口
  Mock.mock('/api/product/list', 'get', product.getProductList)
  Mock.mock('/api/product/category', 'get', product.getCategory)
  
  console.log('✅ Mock服务已启动')
}

export default Mock

// mock/modules/user.js - 用户模块
import Mock from 'mockjs'

export default {
  // 登录接口
  login: (options) => {
    const { username, password } = JSON.parse(options.body)
    
    // 模拟验证逻辑
    if (username === 'admin' && password === '123456') {
      return Mock.mock({
        code: 200,
        message: '登录成功',
        data: {
          token: Mock.mock('@guid'),
          userInfo: {
            id: Mock.mock('@id'),
            username: 'admin',
            nickname: Mock.mock('@cname'),
            avatar: Mock.mock('@image("100x100", "#4A7BF7", "Avatar")'),
            roles: ['admin'],
            permissions: ['user:add', 'user:edit', 'user:delete']
          }
        }
      })
    } else {
      return {
        code: 401,
        message: '用户名或密码错误',
        data: null
      }
    }
  },
  
  // 获取用户信息
  getUserInfo: () => {
    return Mock.mock({
      code: 200,
      message: 'success',
      data: {
        'id|+1': 1,
        'username': '@word(3,10)',
        'nickname': '@cname',
        'avatar': '@image("100x100", "#4A7BF7", "Avatar")',
        'email': '@email',
        'phone': /^1[3-9]\d{9}$/,
        'gender|1': ['male', 'female', 'unknown'],
        'age|20-50': 1,
        'createTime': '@datetime',
        'lastLoginTime': '@datetime',
        'status|1': [0, 1], // 0:禁用, 1:启用
        'roles|1-3': ['admin', 'editor', 'viewer'],
        'department': {
          id: '@integer(1, 10)',
          name: '@ctitle(3,6)'
        }
      }
    })
  },
  
  // 获取用户列表（带分页）
  getUserList: (options) => {
    const params = new URLSearchParams(options.url.split('?')[1])
    const page = parseInt(params.get('page')) || 1
    const size = parseInt(params.get('size')) || 10
    
    return Mock.mock({
      code: 200,
      message: 'success',
      data: {
        total: 100,
        page,
        size,
        'list|10': [{
          'id|+1': (page - 1) * size + 1,
          'username': '@word(3,10)',
          'nickname': '@cname',
          'avatar': '@image("80x80", "#4A7BF7", "头像")',
          'email': '@email',
          'phone': /^1[3-9]\d{9}$/,
          'gender|1': [0, 1, 2], // 0:未知, 1:男, 2:女
          'age|20-60': 1,
          'status|1': [0, 1],
          'createTime': '@datetime("yyyy-MM-dd HH:mm:ss")',
          'roles': () => Mock.mock('@pick(["admin","editor","viewer"], 1, 3)'),
          'department|1': ['技术部', '市场部', '产品部', '运营部', '行政部']
        }]
      }
    })
  }
}

3.2 方案二：Axios拦截器集成

// utils/mock-interceptor.js
import Mock from 'mockjs'
import { isMockEnabled, mockData } from '../mock'

// 创建自定义适配器
export function createMockAdapter(axiosInstance) {
  if (!isMockEnabled) return
  
  axiosInstance.interceptors.request.use(config => {
    const { url, method } = config
    
    // 检查是否有对应的Mock数据
    const mockHandler = findMockHandler(url, method.toLowerCase())
    
    if (mockHandler) {
      config.adapter = function(config) {
        return new Promise((resolve, reject) => {
          setTimeout(() => {  // 模拟网络延迟
            try {
              const data = mockHandler(config)
              const response = {
                data,
                status: 200,
                statusText: 'OK',
                headers: {},
                config
              }
              resolve(response)
            } catch (error) {
              reject(error)
            }
          }, Mock.Random.integer(200, 800)) // 200-800ms随机延迟
        })
      }
    }
    
    return config
  })
}

// 查找Mock处理器
function findMockHandler(url, method) {
  const apiKey = `${method.toUpperCase()} ${url}`
  
  // 支持RESTful风格URL
  for (const [pattern, handler] of Object.entries(mockData)) {
    const [methodPattern, urlPattern] = pattern.split(' ')
    
    if (methodPattern.toLowerCase() === method.toLowerCase()) {
      if (url === urlPattern || 
          urlPattern.includes(':id') && 
          url.startsWith(urlPattern.split(':id')[0])) {
        return handler
      }
    }
  }
  
  return null
}

3.3 方案三：Webpack DevServer代理（Vue/React项目）

// vue.config.js / webpack.config.js
const { createMockMiddleware } = require('mockjs-middleware')

module.exports = {
  devServer: {
    port: 8080,
    before: function(app) {
      // 只在开发环境启用Mock
      if (process.env.NODE_ENV === 'development') {
        // 使用中间件
        app.use(createMockMiddleware({
          basePath: '/api',
          mockDir: path.resolve(__dirname, 'mock'),
          watch: true // 监听mock文件变化
        }))
      }
    },
    
    // 或者使用proxy
    proxy: {
      '/api': {
        target: 'http://localhost:3000',
        changeOrigin: true,
        pathRewrite: {
          '^/api': '/mock-api' // 转发到Mock服务
        },
        bypass: function(req, res, proxyOptions) {
          // 根据条件决定是否使用Mock
          if (req.headers['x-use-mock']) {
            return '/mock' + req.path
          }
        }
      }
    }
  }
}

🎨 四、高级使用技巧

4.1 动态Mock数据

// mock/advanced.js
import Mock from 'mockjs'

export default {
  // 1. 根据请求参数返回不同数据
  searchUsers: (options) => {
    const params = new URLSearchParams(options.url.split('?')[1])
    const keyword = params.get('keyword')
    const page = parseInt(params.get('page')) || 1
    
    // 模拟搜索结果
    let users = []
    
    if (keyword) {
      users = Mock.mock({
        'list|5-15': [{
          'id|+1': 1,
          'name': keyword + Mock.mock('@cword(1,3)'),
          'age|20-40': 1,
          'email': keyword.toLowerCase() + Mock.mock('@email').split('@')[1]
        }]
      }).list
    }
    
    return {
      code: 200,
      data: {
        total: users.length,
        page,
        size: 10,
        list: users.slice((page - 1) * 10, page * 10)
      }
    }
  },
  
  // 2. 模拟文件上传
  uploadFile: (options) => {
    const file = options.body.get('file')
    
    return Mock.mock({
      code: 200,
      data: {
        url: '@url',
        name: file?.name || 'file_' + Mock.mock('@now("timestamp")'),
        size: Mock.mock('@integer(1024, 102400)'),
        type: file?.type || 'image/png',
        uploadTime: '@now("yyyy-MM-dd HH:mm:ss")'
      },
      message: '上传成功'
    })
  },
  
  // 3. 模拟websocket数据流
  mockWebSocketData: () => {
    // 生成实时数据流
    const generateRealTimeData = () => {
      return {
        timestamp: new Date().getTime(),
        'cpu|20-90.2': 1,
        'memory|40-95.2': 1,
        'networkIn|100-10000': 1,
        'networkOut|100-10000': 1,
        'disk|60-99.2': 1,
        'connections|100-1000': 1
      }
    }
    
    return generateRealTimeData()
  },
  
  // 4. 模拟分页数据
  paginationData: (options) => {
    const params = new URLSearchParams(options.url.split('?')[1])
    const page = parseInt(params.get('page')) || 1
    const pageSize = parseInt(params.get('pageSize')) || 10
    const total = 150
    
    // 计算数据范围
    const start = (page - 1) * pageSize
    const end = Math.min(start + pageSize, total)
    
    const data = Mock.mock({
      [`list|${end - start}`]: [{
        'id|+1': start + 1,
        'name': '@cname',
        'status|1': ['pending', 'processing', 'completed', 'failed'],
        'progress|0-100': 1,
        'createTime': '@datetime',
        'updateTime': '@datetime'
      }]
    })
    
    return {
      code: 200,
      data: {
        list: data.list,
        pagination: {
          current: page,
          pageSize,
          total,
          totalPages: Math.ceil(total / pageSize)
        }
      }
    }
  }
}

4.2 TypeScript支持

// types/mock.d.ts
declare namespace Mock {
  interface MockjsRequest {
    url: string;
    type: string;
    body: any;
  }
  
  interface MockjsResponse {
    [key: string]: any;
  }
}

// types/user.ts
export interface User {
  id: number;
  username: string;
  nickname: string;
  avatar: string;
  email: string;
  phone: string;
  gender: number;
  age: number;
  status: number;
  createTime: string;
  roles: string[];
  department: string;
}

export interface LoginResponse {
  code: number;
  message: string;
  data: {
    token: string;
    userInfo: User;
  };
}

// mock/user.ts
import Mock from 'mockjs';
import type { LoginResponse, User } from '../types/user';

const userMock = {
  login: (options: Mock.MockjsRequest): LoginResponse => {
    const { username, password } = JSON.parse(options.body);
    
    if (username === 'admin' && password === '123456') {
      return Mock.mock({
        code: 200,
        message: '登录成功',
        data: {
          token: Mock.mock('@guid'),
          userInfo: {
            id: Mock.mock('@id'),
            username: 'admin',
            nickname: Mock.mock('@cname'),
            avatar: Mock.mock('@image("100x100", "#4A7BF7", "Avatar")'),
            email: Mock.mock('@email'),
            phone: /^1[3-9]\\d{9}$/,
            gender: 1,
            age: Mock.mock('@integer(25, 35)'),
            status: 1,
            createTime: Mock.mock('@datetime'),
            roles: ['admin'],
            department: '技术部'
          } as User
        }
      });
    }
    
    return {
      code: 401,
      message: '用户名或密码错误',
      data: null
    };
  }
};

export default userMock;

└── utils/                 # 工具函数
    └── request.ts         # 封装axios

5.2 环境配置

// .env.development
VUE_APP_API_BASE=/api
VUE_APP_MOCK=true  # 开发环境启用Mock
VUE_APP_MOCK_DELAY=300  # Mock延迟时间

// .env.production
VUE_APP_API_BASE=https://api.yourdomain.com
VUE_APP_MOCK=false  # 生产环境禁用Mock

// config/index.js
const config = {
  development: {
    baseURL: process.env.VUE_APP_API_BASE,
    mock: process.env.VUE_APP_MOCK === 'true',
    mockDelay: parseInt(process.env.VUE_APP_MOCK_DELAY) || 300
  },
  production: {
    baseURL: process.env.VUE_APP_API_BASE,
    mock: false
  }
}

export default config[process.env.NODE_ENV]

5.3 Mock数据规范

// mock/standards.js
export const MockStandards = {
  // 统一响应格式
  responseTemplate: {
    success: (data, message = 'success') => ({
      code: 200,
      message,
      data,
      timestamp: new Date().getTime()
    }),
    
    error: (code = 500, message = '服务器错误', data = null) => ({
      code,
      message,
      data,
      timestamp: new Date().getTime()
    }),
    
    pagination: (list, pagination) => ({
      code: 200,
      message: 'success',
      data: {
        list,
        pagination
      },
      timestamp: new Date().getTime()
    })
  },
  
  // 常用数据模板
  dataTemplates: {
    user: {
      'id|+1': 1,
      'username': '@word(3,10)',
      'nickname': '@cname',
      'avatar': '@image("100x100")',
      'email': '@email',
      'phone': /^1[3-9]\d{9}$/,
      'gender|1': [0, 1, 2],
      'age|20-60': 1,
      'createTime': '@datetime'
    },
    
    product: {
      'id|+1': 1,
      'name': '@ctitle(5,20)',
      'description': '@cparagraph(1,3)',
      'price|10-1000.2': 1,
      'stock|0-1000': 1,
      'status|1': [0, 1],
      'images|1-5': ['@image("200x200")'],
      'category': '@pick(["电子产品","服装","食品","书籍"])'
    }
  }
}

5.4 无缝切换真实接口

// services/request.js
import axios from 'axios'
import MockAdapter from 'axios-mock-adapter'
import mockData from '../mock'

class Request {
  constructor() {
    this.instance = axios.create({
      baseURL: process.env.VUE_APP_API_BASE,
      timeout: 10000
    })
    
    this.mockAdapter = null
    this.initMock()
    this.initInterceptors()
  }
  
  // 初始化Mock
  initMock() {
    if (process.env.VUE_APP_MOCK === 'true') {
      this.mockAdapter = new MockAdapter(this.instance, {
        delayResponse: parseInt(process.env.VUE_APP_MOCK_DELAY) || 300
      })
      
      // 注册Mock接口
      Object.keys(mockData).forEach(key => {
        const [method, url] = key.split(' ')
        this.mockAdapter.on(method.toLowerCase(), url).reply(config => {
          const handler = mockData[key]
          const response = handler(config)
          return [200, response]
        })
      })
      
      console.log('🚀 Mock服务已启动，覆盖接口:', Object.keys(mockData))
    }
  }
  
  // 动态切换Mock状态
  toggleMock(enabled) {
    if (this.mockAdapter) {
      this.mockAdapter.restore()
    }
    
    if (enabled) {
      this.initMock()
    }
    
    localStorage.setItem('mock-enabled', enabled)
  }
  
  // 请求拦截器
  initInterceptors() {

export default new Request()

🚨 六、常见问题解决

6.1 问题：Mock数据太假，不够真实

解决方案： 使用更智能的数据生成器

// mock/realistic-data.js
import Mock from 'mockjs'

export const RealisticData = {
  // 生成更真实的用户数据
  generateRealisticUser() {
    const firstName = Mock.mock('@cfirst')
    const lastName = Mock.mock('@clast')
    
    return {
      id: Mock.mock('@id'),
      username: Mock.mock('@word(6,12)'),
      nickname: firstName + lastName,
      firstName,
      lastName,
      email: `${firstName.toLowerCase()}.${lastName.toLowerCase()}@${Mock.mock('@domain')}`,
      phone: Mock.mock(/^1[3-9]\d{9}$/),
      avatar: `https://randomuser.me/api/portraits/${Mock.mock('@pick(["men","women"])')}/${Mock.mock('@integer(1,99)')}.jpg`,
      birthday: Mock.mock('@date("yyyy-MM-dd")'),
      address: {
        province: Mock.mock('@province'),
        city: Mock.mock('@city'),
        district: Mock.mock('@county'),
        detail: Mock.mock('@cparagraph(1,2)')
      },
      education: Mock.mock('@pick(["本科","硕士","博士","大专"])'),
      jobTitle: Mock.mock('@pick(["工程师","设计师","产品经理","运营","市场"])'),
      company: Mock.mock('@cword(4,8)') + '科技有限公司',
      salary: Mock.mock('@integer(10000, 50000)'),
      interests: Mock.mock('@cword(3,6)').split('').concat(Mock.mock('@cword(3,6)').split('')),
      signature: Mock.mock('@csentence')
    }
  },
  
  // 生成真实的时间序列数据
  generateTimeSeriesData(days = 30) {
    const data = []
    let baseValue = Mock.mock('@integer(100, 500)')
    
    for (let i = 0; i < days; i++) {
      const date = new Date()
      date.setDate(date.getDate() - i)
      
      // 模拟正常的波动
      const change = Mock.mock('@integer(-20, 30)')
      baseValue = Math.max(50, baseValue + change)
      
      data.unshift({
        date: date.toISOString().split('T')[0],
        value: baseValue,
        // 模拟工作日/周末差异
        weekday: date.getDay(),
        isWeekend: date.getDay() === 0 || date.getDay() === 6
      })
    }
    
    return data
  }
}

6.2 问题：如何模拟错误情况？

// mock/error-scenarios.js
export const ErrorScenarios = {
  // 模拟各种HTTP错误
  simulateError(scenario = 'network_error') {
    const scenarios = {
      network_error: {
        code: 'NETWORK_ERROR',
        message: '网络连接失败，请检查网络设置',
        shouldRetry: true
      },
      timeout: {
        code: 'TIMEOUT',
        message: '请求超时，请稍后重试',
        shouldRetry: true
      },
      server_error: {
        code: 'SERVER_ERROR',
        message: '服务器内部错误',
        shouldRetry: false
      },
      unauthorized: {
        code: 401,
        message: '未授权，请重新登录',
        shouldRetry: false,
        redirectTo: '/login'
      },
      forbidden: {
        code: 403,
        message: '权限不足',
        shouldRetry: false
      },
      not_found: {
        code: 404,
        message: '资源不存在',
        shouldRetry: false
      },
      validation_error: {
        code: 422,
        message: '参数验证失败',
        errors: {
          username: ['用户名不能为空', '用户名长度必须在3-20位之间'],
          email: ['邮箱格式不正确']
        }
      },
      rate_limit: {
        code: 429,
        message: '请求过于频繁，请稍后重试',
        retryAfter: 60 // 60秒后重试
      }
    }
    
    return scenarios[scenario] || scenarios.network_error
  },
  
  // 随机返回错误（用于测试）
  randomError(probability = 0.1) {
    if (Math.random() < probability) {
      const errors = [
        'network_error',
        'timeout',
        'server_error',
        'unauthorized',
        'validation_error'
      ]
      const randomError = errors[Math.floor(Math.random() * errors.length)]
      return this.simulateError(randomError)
    }
    return null
  }
}

6.3 问题：Mock影响性能？

优化方案：

// mock/performance.js
export const PerformanceOptimizer = {
  // 1. 懒加载Mock数据
  lazyLoadMock(moduleName) {
    return import(`./modules/${moduleName}.js`)
      .then(module => module.default)
      .catch(() => {
        console.warn(`Mock模块 ${moduleName} 加载失败`)
        return {}
      })
  },
  
  // 2. 数据缓存
  createCachedMock(handler, cacheTime = 60000) {
    let cache = null
    let cacheTimestamp = 0
    
    return function(...args) {
      const now = Date.now()
      
      if (cache && (now - cacheTimestamp) < cacheTime) {
        return Promise.resolve(cache)
      }
      
      return Promise.resolve(handler(...args))
        .then(data => {
          cache = data
          cacheTimestamp = now
          return data
        })
    }
  },
  
  // 3. 批量生成优化
  generateBatchData(template, count, batchSize = 1000) {
    const result = []
    
    for (let i = 0; i < count; i += batchSize) {
      const currentBatchSize = Math.min(batchSize, count - i)
      const batch = Mock.mock({
        [`data|${currentBatchSize}`]: [template]
      }).data
      
      result.push(...batch)
      
      // 避免阻塞主线程
      if (i % (batchSize * 10) === 0) {
        yield result // 使用generator
      }
    }
    
    return result
  }
}

6.4 问题：如何与后端API保持一致？

// mock/api-sync.js
export class ApiSynchronizer {
  constructor() {
    this.apiDefinitions = {}
    this.syncInterval = null
  }
  
  // 从后端获取API定义
  async fetchApiDefinitions() {
    try {
      const response = await fetch('/swagger.json') // 或后端提供的API文档
      const definitions = await response.json()
      this.apiDefinitions = this.parseSwagger(definitions)
      this.updateMockTemplates()
    } catch (error) {
      console.warn('无法获取API定义，使用本地Mock配置')
    }
  },
  
  // 解析Swagger文档
  parseSwagger(swaggerJson) {
    const apis = {}
    
    Object.entries(swaggerJson.paths || {}).forEach(([path, methods]) => {
      Object.entries(methods).forEach(([method, definition]) => {
        const key = `${method.toUpperCase()} ${path}`
        
        apis[key] = {
          path,
          method: method.toUpperCase(),
          parameters: definition.parameters || [],
          responses: definition.responses || {},
          requestBody: definition.requestBody,
          tags: definition.tags || [],
          summary: definition.summary || ''
        }
      })
    })
    
    return apis
  },
  
  // 根据API定义更新Mock模板
  updateMockTemplates() {
    Object.entries(this.apiDefinitions).forEach(([apiKey, definition]) => {
      const { responses } = definition
      const successResponse = responses['200'] || responses['201']
      
      if (successResponse && successResponse.schema) {
        const mockTemplate = this.generateMockFromSchema(successResponse.schema)
        // 更新对应的Mock配置
        this.updateMockConfig(apiKey, mockTemplate)
      }
    })
  },
  
  // 从JSON Schema生成Mock模板
  generateMockFromSchema(schema) {
    // 实现Schema到Mock模板的转换逻辑
    // 这里需要根据具体的Schema结构来实现
    return {}
  },
  
  // 自动同步（定时或监听文件变化）
  startAutoSync(interval = 300000) { // 5分钟
    this.fetchApiDefinitions()
    this.syncInterval = setInterval(() => {
      this.fetchApiDefinitions()
    }, interval)
  },
  
  stopAutoSync() {
    if (this.syncInterval) {
      clearInterval(this.syncInterval)
    }
  }
}

📈 七、监控与调试

7.1 Mock数据监控面板

// mock/monitor.js
export class MockMonitor {
  constructor() {
    this.requests = []
    this.maxRecords = 1000
  }
  
  // 记录Mock请求
  logRequest(config, response, duration) {
    const record = {
      id: this.requests.length + 1,
      url: config.url,
      method: config.method?.toUpperCase(),
      params: config.params,
      data: config.data,
      response: response.data,
      status: response.status,
      duration,
      timestamp: new Date().toISOString(),
      fromMock: true
    }
    
    this.requests.unshift(record)
    
    // 保持记录数量
    if (this.requests.length > this.maxRecords) {
      this.requests.pop()
    }
    
    // 控制台输出
    console.groupCollapsed(`📡 Mock请求: ${record.method} ${record.url}`)
    console.log('请求参数:', record.params || record.data)
    console.log('响应数据:', record.response)
    console.log(`耗时: ${duration}ms`)
    console.groupEnd()
    
    return record
  }
  
  // 获取统计信息
  getStats() {
    const total = this.requests.length
    const byMethod = {}
    const byStatus = {}
    let totalDuration = 0
    
    this.requests.forEach(req => {
      byMethod[req.method] = (byMethod[req.method] || 0) + 1
      byStatus[req.status] = (byStatus[req.status] || 0) + 1
      totalDuration += req.duration
    })
    
    return {
      total,
      avgDuration: total ? totalDuration / total : 0,
      byMethod,
      byStatus,
      recentRequests: this.requests.slice(0, 10)
    }
  }
  
  // 清空记录
  clear() {
    this.requests = []
  }
  
  // 导出数据
  exportData(format = 'json') {
    const data = {
      meta: {
        exportedAt: new Date().toISOString(),
        totalRecords: this.requests.length
      },
      requests: this.requests
    }
    
    if (format === 'json') {
      return JSON.stringify(data, null, 2)
    }
    
    // 也可以支持CSV等其他格式
    return data
  }
}

// 创建全局监控实例
const mockMonitor = new MockMonitor()

// 包装Mock响应函数
export function withMonitoring(handler) {
  return function(config) {
    const startTime = performance.now()
    const response = handler(config)
    const endTime = performance.now()
    
    mockMonitor.logRequest(config, {
      data: response,
      status: 200
    }, endTime - startTime)
    
    return response
  }
}

🎯 总结

关键要点回顾：

1. 明确使用场景：Mock应用于开发、测试阶段，生产环境必须禁用
2. 保持数据真实性：使用合理的数据生成规则，避免"假数据"
3. 统一规范：制定团队Mock数据规范，确保一致性
4. 无缝切换：设计良好的架构，支持Mock/真实接口无感切换
5. 持续维护：Mock数据需要随业务需求同步更新

进阶建议：
