vue3 typescript 不使用nodejs实现 PDF 转 WORD PDF 转图片 WORD 转 PDF 案例
以下是一个使用Vue3和TypeScript实现PDF转Word、PDF转图片和Word转PDF的案例:
-
安装依赖:
npm install pdf-lib docx-pdf-converter -
创建一个名为
PdfUtils.ts的文件,用于实现PDF转Word和PDF转图片的功能:import { PDFDocument, PDFPage } from 'pdf-lib'; import { saveAs } from 'file-saver'; export async function pdfToWord(file: File) { const pdfBytes = await file.arrayBuffer(); const pdfDoc = await PDFDocument.load(pdfBytes); const doc = await window.docxConverter.fromPDF(pdfDoc); const wordFile = new Blob([doc], { type: 'application/vnd.openxmlformats-officedocument.wordprocessingml.document' }); saveAs(wordFile, 'converted.docx'); } export async function pdfToImages(file: File) { const pdfBytes = await file.arrayBuffer(); const pdfDoc = await PDFDocument.load(pdfBytes); const pages = pdfDoc.getPages(); const images: string[] = []; for (let i = 0; i < pages.length; i++) { const page = pages[i]; const imageBytes = await page.render(); const image = new Blob([imageBytes], { type: 'image/png' }); const imageUrl = URL.createObjectURL(image); images.push(imageUrl); } return images; } -
创建一个名为
WordUtils.ts的文件,用于实现Word转PDF的功能:import { jsPDF } from 'jspdf'; export function wordToPdf(file: File) { const reader = new FileReader(); reader.onload = function (e) { const data = new Uint8Array(e.target.result as ArrayBuffer); const doc = new jsPDF(); doc.setFontSize(12); doc.text(20, 20, data); doc.save('converted.pdf'); }; reader.readAsArrayBuffer(file); } -
在Vue组件中使用上述工具类:
<template> <div> <input type="file" @change="onFileChange" accept=".pdf, .docx"> <button @click="convertToWord">PDF to Word</button> <button @click="convertToImages">PDF to Images</button> <button @click="convertToPdf">Word to PDF</button> <div v-if="convertedImages.length > 0"> <h2>Converted Images:</h2> <div v-for="imageUrl in convertedImages" :key="imageUrl"> <img :src="imageUrl" alt="Converted Image" style="width: 200px; height: auto;"> </div> </div> </div> </template> <script lang="ts"> import { defineComponent, ref } from 'vue'; import { pdfToWord, pdfToImages } from './PdfUtils'; import { wordToPdf } from './WordUtils'; export default defineComponent({ setup() { const convertedImages = ref<string[]>([]); function onFileChange(event: Event) { const target = event.target as HTMLInputElement; const file = target.files?.[0]; // Do something with the selected file } async function convertToWord() { await pdfToWord(file); } async function convertToImages() { const images = await pdfToImages(file); convertedImages.value = images; } function convertToPdf() { wordToPdf(file); } return { onFileChange, convertToWord, convertToImages, convertToPdf, convertedImages }; }, }); </script>
注意:以上代码只是一个简单的示例,实际使用时可能需要根据具体的需求进行调整和优化。另外,上述示例中使用了file-saver库来保存文件,pdf-lib库来处理PDF文件,docx-pdf-converter库来处理Word文件。请根据实际情况在项目中添加这些依赖
