跟我一起做一个vue的小项目（七）

先看下我们所做项目的效果

这些数据都是我们在data中定义的，不是从后端数据中请求的。那么

接下来我们使用axios渲染数据

npm install axios --save

每个组件里面的数据都不相同，但是单个的组件去进行数据请求的话，那么ajax请求还是太多了，我们在home.vue中发起一个请求
我们使用mock数据，在static中创建一个mock文件夹写入json文件
vue中提出了一个转发功能，我们写的接口路径就可以直接同线上的一致

            }
        ]


    }
}

config中我们添加如下内容，它主要是对项目做一个转发功能

在home.vue中我们请求这个数据

<template>
  <div>
  <home-header></home-header>
  <home-swiper></home-swiper>
  <home-icons></home-icons>
  <home-recommend></home-recommend>
  <home-weekend></home-weekend>
  </div>
</template>
<script>
import HomeHeader from './components/Header'
import HomeSwiper from './components/Swiper'
import HomeIcons from './components/Icons'
import HomeRecommend from './components/Recommend'
import HomeWeekend from './components/Weekend'
import axios from 'axios'
export default {
  name: 'Home',
  components: {
    HomeHeader,
    HomeSwiper,
    HomeIcons,
    HomeRecommend,
    HomeWeekend
  },
  methods: {
    getHomeInfo () {
      axios.get('/api/index.json')
        .then(this.getHomeInfoSucc)
    },
    getHomeInfoSucc (res) {
      console.log('res', res)
    }
  },
  mounted () {
    this.getHomeInfo()
  }
}
</script>
<style>
</style>

我们可以看到数据可以打印出来

接下来我们要将从后台数据（我们模拟的数据）传递给子组件，并让其渲染数据。
我们首先在header中进行city的传值


我们在home.vue写入这个

运行发现city值是可以取到的
我们用同样的方法取其他的值
放一下完整的代码

//home.vue
<template>
  <div>
  <home-header :city="city"></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>
<script>
import HomeHeader from './components/Header'
import HomeSwiper from './components/Swiper'
import HomeIcons from './components/Icons'
import HomeRecommend from './components/Recommend'
import HomeWeekend from './components/Weekend'
import axios from 'axios'
export default {
  name: 'Home',
  components: {
    HomeHeader,
    HomeSwiper,
    HomeIcons,
    HomeRecommend,
    HomeWeekend
  },
  data () {
    return {
      city: '',
      swiperList: [],
      iconList: [],
      recommendList: [],
      weekendList: []
    }
  },
  methods: {
    getHomeInfo () {
      axios.get('/api/index.json')
        .then(this.getHomeInfoSucc)
    },
    getHomeInfoSucc (res) {
      res = res.data
      if (res.ret && res.data) {
        const data = res.data
        this.city = data.city
        this.swiperList = data.swiperList
        this.iconList = data.iconList
        this.recommendList = data.recommendList
        this.weekendList = data.weekendList
      }
    }
  },
  mounted () {
    this.getHomeInfo()
  }
}
</script>
<style>
</style>
