如何将docx放入JSZIP中

Question

我无法将docx/rtf插入到zip文件夹中。我使用的是React TypeScript JSZip docx.

在我看来，问题是我不能将文件类型转换为Blob类型。

我正在使用docx创建一个word文件，我返回一个file类型的文档，我不能把它放在JSZip创建的word文件夹中。

import { saveAs } from "file-saver";
import imageSize from 'image-size';
import {
Document,
Paragraph,
Table,
TableCell,
TableRow,
Packer,
WidthType,
BorderStyle,
AlignmentType,
HeadingLevel,
convertInchesToTwip,
VerticalAlign,
TextRun,
TableOfContents,
ImageRun,
Media,
UnderlineType,
ShadingType,
} from "docx";
interface forzip {
array: any[];
wordHeaders: string[];
dataKeys: string[];
image?: any;
headerName?:string
}
export const export2zip = (
arrforzip:forzip[]
) => {
var zip = new JSZip();
var word = zip.folder("word");
arrforzip.map(function(forword,ind) {
const filename: string = "exported_file.rtf";
const dataToConvertWord = (arrforzip);
const doc:any = createWordClick(dataToConvertWord);
const blob = new Blob([doc as BlobPart], {
type: 'application/msword',
});
//NOT WORK
word?.file(
`${forword.headerName}.rtf`,
blob,
{ binary: true }
);
//NOT WORK
word?.file(
`${forword.headerName}.rtf`,
doc,
{ binary: true }
);
//NOT WORK
Packer.toBlob(doc).then(blob => {
word?.file(
`${forword.headerName}.rtf`,
blob,
{ binary: true }
);
})
})
zip.generateAsync({type:"blob",compression: "DEFLATE" ,mimeType: "application/vnd.openxmlformats-officedocument.wordprocessingml.document", }).then(function (blob: any) {
zip.generateAsync({type:"blob",compression: "DEFLATE" ,mimeType: "application/vnd.openxmlformats-officedocument.wordprocessingml.document" })
.then(function(content: string | Blob) {FileSaver.saveAs(content, `examples.zip`);});
});

对于Packer你应该使用第三个选项。blob和call zip。generateAsync只在promise Packer之后一次。toBlob将得到解决。zip归档文件的mime类型应该是application/zip(这是默认值，您可以不传递此参数)

Packer.toBlob(doc).then(blob => {
word?.file(
`${forword.headerName}.rtf`,
blob,
{ binary: true }
);
zip.generateAsync({type:"blob",compression: "DEFLATE" })
.then(content => FileSaver.saveAs(content, `examples.zip`));
);
