需要从原有数据中拿到的是

username,
paidCourses,
admin,
email

这四项。

mongoimport  -d newcat -c contracts   --file contracts.json

const fs = require('fs')

const removeLastEl = arr => arr.slice(0, -1)

const jsonToArr = json =>
 json.map(t => {
   return JSON.parse(t)
 })

const getJson = path => removeLastEl(fs.readFileSync(path, 'utf-8').split('\n'))

const userArr = jsonToArr(getJson('../users.json'))

const selectEl = arr =>
 arr.map(t => {
   const { username, paidCourses, admin } = t
   return {
     username,
     paidCourses,
     member: admin
   }
 })

const arrToJson = arr => arr.map(t => JSON.stringify(t)).join('\n')

const userJson = arrToJson(selectEl(userArr))
const outputFile = 'contracts.json'
fs.writeFileSync(outputFile, userJson)
console.log('saved to ' + outputFile)

总体思路是：

把 contracts 中包含的客户权益，在用户登录和注册的时候，连同其他用户信息一起，保存到 jwt token 中
