Vue3中实现电子书PDF转图片及翻页效果的解决方案

首先，我们需要安装两个库：pdfjs-dist和turn.js。你可以使用npm进行安装：

npm install pdfjs-dist turn.js

然后，在Vue3项目中创建一个新的组件。例如，我们创建一个名为PdfViewer.vue的组件。
在PdfViewer.vue中，我们可以编写如下代码：

<template>
<div class="pdf-viewer">
<div v-for="page in pages" :key="page.num" class="page">
<img :src="page.img">
</div>
</div>
</template>
<script>
import { pdfjs } from 'pdfjs-dist/build/pdf';
import 'turn.js';
export default {
data() {
return {
pdfDoc: null,
currentPage: 1,
pages: []
}
},
mounted() {
this.loadDocument('your-pdf-file-path.pdf');
},
methods: {
async loadDocument(url) {
const loadingTask = pdfjs.getDocument(url);
this.pdfDoc = await loadingTask.promise;
const totalPages = this.pdfDoc.numPages;
for (let i = 1; i <= totalPages; i++) {
const page = await this.pdfDoc.getPage(i);
const canvas = document.createElement('canvas');
const context = canvas.getContext('2d);
const viewport = page.getViewport({scale: 1.5});
canvas.height = viewport.height;
canvas.width = viewport.width;
await page.render({canvasContext: context, viewport}).promise;
const img = canvas.toDataURL('image/png');
this.pages.push({num: i, img: img});
}
}
},
methods: {
nextPage() {
if (this.currentPage < this.pages.length) {
this.currentPage++;
}
},
prevPage() {
if (this.currentPage > 1) {\n
