vue2.0使用vue-pdf(简单版本)

1.引入vue-pdf（vue-pdf版本：4.3.0，vue版本：2.6.14）

npm install --save vue-pdf

2.引入本地文件（放public文件夹下用于测试。后期用接口返回的地址）

111.pdf：自己随意生成的一个

3.页面按需引入

<script>
import Pdf from "vue-pdf"
export default {
  components: { Pdf }
}
</script>

4.完整代码

pdfShow.vue

<template>
  <div>
    <div class="tools">
      <el-button type="primary" @click.stop="prePage">上一页</el-button>
      <el-button type="primary" @click.stop="nextPage">下一页</el-button>
      <el-button type="primary">{{ currentPage }}/{{ pageCount }}</el-button>
      <el-button type="primary" @click.stop="scaleD">放大</el-button>
      <el-button type="primary" @click.stop="scaleX">缩小</el-button>
     
    </div>
    <div class="pdf">
