Я пытался использовать pdfjs-dist.
получить большой ответ JSON.
var PDFJS=require('pdfjs-dist');
PDFJS.getDocument({ url: 'p1.pdf', password: '' }).then(function(pdf_doc)
{
console.log(pdf_doc);
}).catch(function(error) {
// incorrect password
// error is an object having 3 properties : name, message & code
});
Ответ
Это весь ответ, который я получаю.
но мне нужен ответ в буфере.
Можно ли преобразовать в буфер.
