vue如何使用iframe嵌入网页

this.$router.push({ name: 'userTemplate', params: { reportUrl: reportUrl, reportType: reportType }})

<template>
 <div> 
  <iframe v-if="reportType==0" name = "child" id = "child" v-bind:src="reportUrl"
  width="auto" height="300"
   frameborder="0" scrolling="no" 
  ></iframe>
 
 <div v-if="reportType==1" v-html="htmlContent"
 width="auto" height="300" scrolling="no" ></div>
 
 </div>
</template>
 
<script>
import {
 getFile
} from '@/api/report'
export default {
 mounted() {
  /**
   * iframe-宽高自适应显示
   */
  function changeMobsfIframe() {
   const mobsf = document.getElementById('child')
   const deviceWidth = document.body.clientWidth
   const deviceHeight = document.body.clientHeight
   mobsf.style.width = (Number(deviceWidth) - 30) + 'px' // 数字是页面布局宽度差值
   mobsf.style.height = (Number(deviceHeight) - 80) + 'px' // 数字是页面布局高度差
  }
 
  changeMobsfIframe()
 
  window.onresize = function() {
   changeMobsfIframe()
  }
 },
 
 data() {
  return {
   htmlContent: '',
   reportUrl: '',
   reportType: ''
  }
 },
 created() {
  // this.fileName = '../static/file/' + this.$route.params.report_url
  this.reportUrl = this.$route.params.reportUrl
  this.reportType = this.$route.params.reportType
  if (this.reportType == 1) {
   getFile(this.reportUrl).then(res => {
    if (res.code === 200) {
     this.htmlContent = res.data
    }
   })
  }
 }
}
</script>
 
<style rel="stylesheet/scss" lang="scss" scoped>
 
</style>

//读取文件
 @RequestMapping("/getFile")
  @ResponseBody
 public HttpResult getFile(String reportUrl){
  StringBuilder result = new StringBuilder();
     try{
     
     FileSystemResource resource = new FileSystemResource("D:"+File.separator+"test"+File.separator+reportUrl);
     File file = resource.getFile();
       BufferedReader br = new BufferedReader(new FileReader(file));
       String s = null;
       while((s = br.readLine())!=null){
         result.append(System.lineSeparator()+s);
       }
       br.close();  
       return HttpResult.getSuccessInstance(result);
     }catch(Exception e){
       e.printStackTrace();
       return HttpResult.getFailedInstance("读取异常");
     } 
 }
