How to request local json using vue

This time I will show you how to use vue to request local json, and what are the precautions for using vue to request local json. The following is a practical case, let's take a look.

Find the webpack.dev.conf.js file in the build folder, add

const express = require('express')
const app = express()
const appData = require('../data.json') // 加载本地json文件
const seller = appData.seller // 获取对应本地数据
const goods = appData.goods
const ratings = appData.ratings
const apiRoutes = express.Router()
app.use('/api',apiRoutes)

after const portfinder = require('portfinder'), then find devServer, and insert the following code:

 //然后找到devSeerver，在里面添加
  before (app) {
   app.get('/api/seller',(reg,res) => {
    res.json({
     errno: 0,
     data: seller
    }) // 接口返回json数据，上面配置的数据seller就复制给data请求后调用
   }),
   app.get('/api/goods',(reg,res) => {
    res.json({
     errno: 0,
     data: goods
    }) // 接口返回json数据，上面配置的数据goods就复制给data请求后调用
   }),
   app.get('/api/ratings',(reg,res) => {
    res.json({
     errno: 0,
     data: ratings
    }) // 接口返回json数据，上面配置的数据ratings就复制给data请求后调用
   })
  }

Request access

<script>
import header from './components/header/header.vue'
const ERR_OK = 0
export default {
 data () {
  return {
   seller: {}
  }
 },
 created () {
  this.$http.get('/api/seller').then((response) => {
   response = response.body; // 获取到数据
   if (response.errno === ERR_OK) {
    this.seller = response.data;
    console.log(this.seller);
   }
  })
 },
 components: {
  'v-header': header
 }
}
</script>
