我一直在尝试将此数据pdf-lib传递到使用:
var byteCharacters = atob(data);
var byteNumbers = new Array(byteCharacters.length);
for (var i = 0; i < byteCharacters.length; i++) {
byteNumbers[i] = byteCharacters.charCodeAt(i);
}
var byteArray = new Uint8Array(byteNumbers);
this.document = await pdfLib.getDocument([byteArray]).promise
或只是:
this.document = await pdfLib.getDocument({data}).promise
这两种情况都会导致错误，表明PDF格式不正确。有人知道该怎么做吗?
哦，如果我使用旧版本的pdf-lib，看起来它可以工作
"pdfjs-dist": "2.3.200",
和做的事:
this.document = await pdfLib.getDocument(Buffer.from(data, 'base64')).promise
那么就可以了
