Question

我正在尝试使用pdf.js从pdf文档中提取纯文本，由于某种原因，我无法克服Invalid PDF structure错误。

我的代码如下：

const pdfjslib = require('pdfjs-dist');

const pdfPath = 'https://www.corenet.gov.sg/media/2268607/dc19-07.pdf'

var loadingTask = pdfjslib.getDocument(pdfPath);
loadingTask.promise.then(async (doc) => {
    console.log(doc);
    return null
})
.catch((err)=>{
    console.log(err)
});

我尝试了来自同一域的其他pdf文档，但都引发了相同的错误：

来自其他域的其他pdf似乎有效。请注意，从上述域下载pdf效果很好，并且可以在Chrome浏览器中查看。我怀疑pdf文档已损坏。我没有实现任何前端代码，因为以上代码的意图是将其托管在云上。
