Answer 1

如果您使用 libreoffice-convert 库，那就很简单了。

代码：

const libre = require('libreoffice-convert');

const fs = require('fs');

function convertToPdf(filePath) {

   const file = fs.readFileSync(filePath);
 
   libre.convert(file, extend, undefined, (err, done) => {
      if (err) {
        console.log(`Error converting file: ${err}`);
      }
 
      fs.writeFileSync('outputFile.pdf', done);
  });
}

Answer 2

欢迎来到！

您可以为此使用一个包装。尽管我找到了两个软件包，但要求从看起来是从磁盘而不是从缓冲区读取文件。

1）docx-pdf：def my_aug_func(x): ... return aug_x dataset = tf.data.TextLineDataset(RAW_DATA_FPATH) dataset = dataset.map(my_aug_func)

npm i docx-pdf

2）word2pdf：const docxConverter = require('docx-pdf'); docxConverter('./input.docx','./output.pdf', (err, result) => { if (err) console.log(err); else console.log(result); // writes to file for us });

npm i word2pdf

另一种选择是使用诸如https://github.com/Api2Pdf/api2pdf.node#readme之类的外部API（如果要处理敏感数据，甚至可以自己托管它）。

如何在Node.js中将Word文档转换为PDF
