config>index.js  设置代理，让api路径跳转到虚拟数据的路径

assetsSubDirectory: 'static',    assetsPublicPath: '/',    proxyTable: {        '/api': {            target: 'http://localhost:8080',            pathRewrite: {                '^/api': '/static/mock'            }        }

在子组件请求数据

methods: {    getHomeInfo () {      axios.get('/api/index.json').then(this.getHomeInfoSucc)    这里/api会被代理成/static/mock虚拟数据的文件路径    },    getHomeInfoSucc (res) {   对数据进行处理      res = res.data  将数据里面的data拿到      if (res.ret && res.data) {  做一个判断，当数据成功接收且数据不为空        const data = res.data          this.city = data.city        this.swiperList = data.swiperList        this.iconList = data.iconList        this.recommendList = data.recommendList        this.weekendList = data.weekendList      }      console.log(res)    }  },  mounted () {   在mounted执行时获取数据    this.getHomeInfo()  }
