vue-pdf預覽base64資料為pdf

// data為後端給的base64格式的pdf
import { data } from "../../tempData";
import pdf from 'vue-pdf'
// 解決部分文字不顯示的問題
import CMapReaderFactory from 'vue-pdf/src/CMapReaderFactory.js'
// html
    <pdf v-for="i in numPages" :key="i" :src="src" :page="i" ref="myPdfComponent"></pdf>
  data () {
    return {
      src: '',
      numPages: 0,
      page: 1,
      currentPage: 0
    };
  }，
  components: {
    pdf
  },
  mounted () {
    let da = data.fileToBase64
    let datas = 'data:application/pdf;base64,' + da
    this.src = pdf.createLoadingTask({ url: datas, CMapReaderFactory });
    this.src.promise.then(pdf => {
      this.numPages = pdf.numPages;
    });
  },
