如何将带有 npm 'docx' 包的图像添加到 Word 文档？

Question

我发现这个 npm 包docx有助于用 javascript 生成 word 文档文件： https : //github.com/dolanmiu/docx

我想在我的doc添加一个图像，但我似乎无法弄清楚是如何发生的，或者发生了什么。 我在这上面花了好几个小时，但是文档对于像我这样的菜鸟来说还不够全面。

这是我尝试过的：

尝试#1：

import React, { useState } from "react";
import * as fs from "fs";
import moment from "moment";
import { Document, Packer, Paragraph, Media } from "docx";
import { saveAs } from "file-saver";
const GenerateDoc = () => {
    const doc = new Document();
    const logo = Media.addImage(doc, fs.readFileSync("myImage.png"), 200, 200); // ERROR HERE: "fs.readFileSync is not a function
    doc.addSection({children: [new Paragraph(logo)]});
    const download = () => {
        // download function...
    };
    return (
        <div>
            <button onClick={() => {download()}}>Generate</button>
        </div>
    );
};
export default GenerateDoc;

输出 #1：类型错误：fs__WEBPACK_IMPORTED_MODULE_2__.readFileSync 不是函数

尝试#2：

import React, { useState } from "react";
import moment from "moment";
import { Document, Packer, Paragraph, Media } from "docx";
import { saveAs } from "file-saver";
const GenerateDoc = () => {
    const doc = new Document();
    const logo = doc.createImage("myImage.png"); // ERROR HERE: doc.createImage is not a function
    doc.addSection({children: [new Paragraph(logo)]});
    const download = () => {
        // download function...
    };
    return (
        <div>
            <button onClick={() => {download()}}>Generate</button>
        </div>
    );
};
export default GenerateDoc;

输出 #2：类型错误：doc.createImage 不是函数

什么工作：

import React, { useState } from "react";
import moment from "moment";
import { Document, Packer, Paragraph, Media } from "docx";
import { saveAs } from "file-saver";
const GenerateDoc = () => {
    const doc = new Document();
    const logo = Media.addImage(doc); // returns a blank image in the word document since I didn't specify a file.
    doc.addSection({
        children: [new Paragraph(logo)]
    });
    const download = () => {
        // download function...
    };
    return (
        <div>
            <button onClick={() => {download()}}>Generate</button>
        </div>
    );
};
export default GenerateDoc;

编辑：

尝试#3：

import React, { useState } from "react";
import moment from "moment";
import { Document, Packer, Paragraph, Media } from "docx";
import { saveAs } from "file-saver";
const GenerateDoc = () => {
    const doc = new Document();
    const logo = Media.addImage(doc, '../myImage.png'); // ERROR: InvalidCharacterError: Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded.
    doc.addSection({
        children: [new Paragraph(logo)]
    });
    const download = () => {
        // download function...
    };
    return (
        <div>
            <button onClick={() => {download()}}>Generate</button>
        </div>
    );
};
export default GenerateDoc;

输出 #3：InvalidCharacterError：无法在 'Window' 上执行 'atob'：要解码的字符串未正确编码。

DOCX作者在这里，

这是一个 docx 的示例，在 React 中带有图像（base64 和来自互联网的 URL 请求）：

一种方法是通过导入加载文件，转换为 blob，然后使用 ImageRun。

 import LetterHead from '../images/letterhead.jpg'; ... const export = async () => { const letterHead = await fetch(LetterHead); const doc = new Document({ sections: [ ... new ImageRun ({ data : await letterHead.blob() ... ... Packer.toBlob(doc)... }
