1. 安装依赖：npm i mocker-api mockjs -D

2. 在development模式对应的webpack 配置下添加：

devSever.before = function(app, server) {
  // console.log('MOCK', process.env)
  if(process.env.MOCK) {
    // mocker-api
    apiMocker(app, path.resolve(__dirname, '../mock'))
  }
}

3. 添加对应的mock数据接口：

// mock/index.js
const invitation = require('./invitation')

module.exports = {
  ...invitation
}

// mock/invitation/index.js
const Mock = require('mockjs')
const Random = Mock.Random

var data = Mock.mock({
  'list|25': [
    {
      // 属性 id 是一个自增数，起始值为 1，每次增 1
      'id|+1': 1,
      parentNickName: '前端人人@id',
      nickName: '前端人人@id',
      inviteAvatar: '', // Random.dataImage('60x60'),
      avatar: '', // Random.dataImage('60x60'),
      inviteTime: new Date().getTime(),
      validStatus: Random.pick([1, 2, 3, 4])
    }
  ]
})

module.exports = {
  'GET /api/inviteInfo/selflist': (req, resp) => {
    // console.log('data', data)
    const { page: pPage } = req.query;
    // let page = 0;
    const page = parseInt(pPage || '1')
    let pageSize = 15;
    let startIdx = (page - 1) * pageSize;
    let endIdx = page * pageSize;
    return resp.json({
      code: 200,
      data: data.list.slice(startIdx, endIdx),
      message: '查询成功',
      pageCount: Math.ceil(data.list.length / pageSize),
      currentPage: page,
    })
  },
  //...
}

4. package.json 文件添加运行脚本：

"start:mock": "cross-env MOCK=true npm run start",

注：如果windows环境下MOCK=true设置无效，请安装 cross-env 依赖。
