PDF.js-预览pdf文件

1.安装引入

npm i vue-pdf-signature

import Pdf from 'vue-pdf-signature';
// 引入CMapReaderFactory库 解决动态文字丢失问题
import CMapReaderFactory from 'vue-pdf-signature/src/CMapReaderFactory.js';

2.使用方式

data() {
    return {
      pageCount: 0,
    }
}

// 方法里调用  通过文件路径
const loadingTask = window.location.origin + file[0].filePath;
this.pdfSrc = Pdf.createLoadingTask({
     url: loadingTask,
     CMapReaderFactory,
});
this.pdfSrc.promise.then(pdf => {
this.pageCount = pdf.numPages;
    this.loading = false;
}).catch(err => {
   this.$message.warning('预览失败,请重试');
   console.log(err);
});

3.template里渲染

          <div v-for="i in pageCount" :key="i" style="outline: 1px solid #ccc;margin: 15px auto;">
            <!-- pdf预览 -->
            <pdf ref="pdfRef" :src="pdfSrc" :page="i" />
          </div>
