好好学习 ，天天向上。Are you ready?

代码奉上！！！！！！！！！

首先登陆阿里云控制台，创建应用

选模板，创建名称

通过编辑预览项目

发布大屏发布成功，可以去直接访问网址，通过vue项目内嵌iframe 来实现dataV的引用

demo1 vue代码示例 （此处为未设置Token验证）

<template>
  <div class="block">
    <iframe
      :width="searchTableWidth"
      :height="searchTableHeight"
      :src="reportUrl"
      style="border:none"
    />
  </div>
</template>

<script>
export default {
  data() {
    return {
      reportUrl: '',
      searchTableHeight: 0,
      searchTableWidth: 0
    }
  },
  watch: {
    '$route': function() {
      // 监听路由变化
      this.reportUrl = this.$route.meta.pathUrl
    }
  },
  created() {
   this.reportUrl = 'http://datav.aliyun.com/share8888888888888888888888'
  },
  mounted() {
    window.onresize = () => {
      this.widthHeight() // 自适应高宽度
    }
    this.$nextTick(function() {
      this.widthHeight()
    })
  },
  methods: {
    widthHeight() {
      this.searchTableHeight = window.innerHeight + 'px'
      this.searchTableWidth = window.innerWidth + 'px'
    }
  }
}
</script>
<style lang="scss" scoped>
