去哪儿的 源码 个人解析（1） axios

1.导入axios

import axios from 'axios'

2.直接在组件的 methods 中使用

  methods: {
    getHomeInfo () {
      axios.get('/api/index.json?city=' + this.city)
        .then(this.getHomeInfoSucc)
    },
    getHomeInfoSucc (res) {
      res = res.data
      if (res.ret && res.data) {
        const data = res.data
        this.swiperList = data.swiperList
        this.iconList = data.iconList
        this.recommendList = data.recommendList
        this.weekendList = data.weekendList
      }
    }
  },

 axios.get('/api/index.json?city=' + this.city) 解释 数据存放的位置

修改各组件的<template>

<template>
  <div>
    <home-header></home-header>
    <home-swiper :list="swiperList"></home-swiper>
    <home-icons :list="iconList"></home-icons>
    <home-recommend :list="recommendList"></home-recommend>
    <home-weekend :list="weekendList"></home-weekend>
  </div>
</template>

返回数据设置为空

  data () {
    return {
      lastCity: '',
      swiperList: [],
      iconList: [],
      recommendList: [],
      weekendList: []
    }
  },

组件传数据，父组件传递给子组件

export default {
  name: 'HomeRecommend',
  props: {
    list: Array
  }
}

 props ：父组件传递给子组件用到props
