When I read certain PDF files(maybe not standard pdf), an exception is thrown,
I hope I can read them normally
Environment
Which environment were you using when you encountered the problem?
$ python -m platform
macOS-10.16-x86_64-i386-64bit
$ python -c "import pypdf;print(pypdf.__version__)"
3.2.1
Code + PDF
This is a minimal, complete example that shows the issue:
from io import BytesIO
import requests
from pypdf import PdfReader
if __name__ == '__main__':
url = "https://gz-gov-open-doc.oss-cn-gz-ysgzlt-d01-a.ltops.gzdata.com.cn/1024FPA/open/37560735-0101-4199-8dd6-c9015c438f13.pdf"
res = requests.get(url)
print(res.text)
PdfReader(BytesIO(res.content))Share here the PDF file(s) that cause the issue. The smaller they are, the
better. Let us know if we may add them to our tests!
