[vue-pdf] npm连接:https://www.npmjs.com/package/vue-pdf
安装vue-pdf
npm i vue-pdf
1.解决字体问题
将node_modules/pdfjs-dist/cmaps文件夹复制到public文件夹下 (找不到的可以看下代码怎么写的,node_modules/vue-pdf/src/CMapReaderFactory.js)
2.上传预览
<template> <div> <el-upload class="upload-demo" drag action="#" :auto-upload="false" :on-change=‘fileChange‘ :limit=‘1‘ multiple> <i class="el-icon-upload"></i> <div class="el-upload__text">将文件拖到此处,或<em>点击上传</em></div> <div class="el-upload__tip" slot="tip"> 只能上传jpg/png文件,且不超过500kb </div> </el-upload> <pdf :src="pdfURL"></pdf> </div> </template>
<script>
import pdf from "vue-pdf";
export default {
components: {
pdf,
},
data() {
return {
pdfURL: "",
};
},
methods: {
fileChange(file){
//拿到上传的文件
let file=file.raw
//转成二进制
let blob=new Blob([file])
//本地创建新的连接地址
this.pdfURL=URL.createObjectURL(blob)
//解决字体问题、第二次加载字体不显示问题
this.pdfURL= pdf.createLoadingTask({
url: this.pdfURL ,
cMapUrl: ‘/cmaps/‘,
cMapPacked: true})
}
},
};
