通过ajax在首页请求一次数据，然后把数据传递给子组件。

Home.vue:

新建data:

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

请求ajax数据成功后：

getHomeInfoSucc (res) {
// console.log(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
}
}

通过属性绑定传递给子组件：

<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>

在子组件中通过props属性接收：

Header.vue:

<script>
export default {
name: 'HomeHeader',
props: {
city: String
}
}

使用传递过来的city：

<div class="header-right"> {{this.city}} <span class="iconfont arrow-icon">&#xe64a;</span> </div>

Swiper.vue:

props: { list: Array },

解决默认展示最后一张图片：
