Vue2.5通過(guò)json文件讀取數(shù)據(jù)的方法

const express = require('express')
const app = express()
var appData = require('../data.json')//加載本地?cái)?shù)據(jù)文件的路徑
var leftMenu = appData.leftMenu //獲取對(duì)應(yīng)的本地?cái)?shù)據(jù)
var 數(shù)據(jù)名稱 = appData.選擇項(xiàng)
var apiRoutes = express.Router()
app.use('/api', apiRoutes)

before(app) {
 app.get('/api/leftmenu', (req, res) => {
 res.json({
 errno: 0,
 data: leftMenu
 })//接口返回json數(shù)據(jù)，上面配置的數(shù)據(jù)seller就賦值給data請(qǐng)求后調(diào)用
 }),
 app.get('/api/數(shù)據(jù)', (req, res) => {
 res.json({
 errno: 0,
 data: 數(shù)據(jù)（與上面數(shù)據(jù)名稱對(duì)應(yīng)）
 })
 })
}

created(){
 this.$http.get('api/leftmenu').then((response) => {
 console.log(response)
 this.leftMenu = response.body.data //數(shù)據(jù)位置
 })
} 
data(){
 return{
 leftMenu:[]; 
 }
}
