vue中使用axios发送ajax请求，获取数据

1、先准备好一个api接口 http://www.imooc.com/api/home/slider

2、安装插件 cnpm install --save axios

3、api/slider.js

import axios from 'axios';

//获取幻灯片数据 ajax
export const getSliders=()=>{
    return axios.get('http://www.imooc.com/api/home/slider').then(res=>{
        
        if(res.data.code===0){
            console.log(res.data.slider);
            return res.data.slider;//返回是数据
        }

        throw new Error('没有成功获取到数据');
    }).catch(err=>{
        console.log(err);
        //错误处理
        return [{       
            linkUrl:'www.baidu.com',
            picUrl:require('assets/img/404.png')
        }]
    });
}

4、在 components/slider/index.vue中引入该方法

<template>
  <swiper ref="mySwiper" :options="swiperOptions">
    <swiper-slide v-for="(slider,index) in sliders" :key="index">
        <a :href="slider.linkUrl">
            <img :src="slider.picUrl">
        </a>
    </swiper-slide>
    <div class="swiper-pagination" slot="pagination"></div>
    <div class="swiper-button-prev" slot="button-prev"></div>
    <div class="swiper-button-next" slot="button-next"></div>
  </swiper>
</template>

<script>
import { Swiper, SwiperSlide } from 'vue-awesome-swiper';
import 'swiper/css/swiper.css';
import { getSliders } from 'api/slider';
 
export default {
    name:"Slider",
    title: 'Autoplay',
    components:{
        Swiper,
        SwiperSlide
    },
    data() {
      return {
        sliders:[],
        swiperOptions: {
          spaceBetween: 30,
          centeredSlides: true,
          autoplay: {
            delay: 2500,
            disableOnInteraction: false
          },
          loop: true,
          pagination: {
            el: '.swiper-pagination',
            clickable: true
          },
          navigation: {
            nextEl: '.swiper-button-next',
            prevEl: '.swiper-button-prev'
          }
        }
      }
    },
    created(){
        //一般在created里获取远程数据
        this.getSliders();      
    },
    computed: {
      swiper() {
        return this.$refs.mySwiper.$swiper;
      }
    },
    mounted() {
      //console.log('Current Swiper instance object', this.swiper);
      this.swiper.slideTo(3, 1000, false);
    },
    methods:{
        getSliders(){
            return getSliders().then(data=>{
                //console.log(data);
                this.sliders=data;
            });
        }
    }
  }
</script>

<style lang="scss" scoped>
    .swiper-container{
        width:100%;
        height:180px;
    }
    .swiper-slide a{
        display:block;
        width:100%;
        height:100%;

        & img{
            width:100%;
            height:100%;
        }
    }
</style>
