python - 如何在 python pdfminer3k 中解决这个警告？

问题描述

当我在 python IDLE 中运行这些代码时，我收到了这个警告，如何解决这个问题？

警告：根：无法找到 objid= nnn

# -*- coding: utf-8 -*- 
from pdfminer.pdfinterp import PDFResourceManager, process_pdf
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from io import StringIO
from io import open

def readPDF(pdfFile):
    rsrcmgr = PDFResourceManager()
    retstr = StringIO()
    laparams = LAParams()
    device = TextConverter(rsrcmgr, retstr, laparams=laparams)

    process_pdf(rsrcmgr, device, pdfFile)
    device.close()

    content = retstr.getvalue()
    retstr.close()
    return content


def saveTxt(txt):
    with open("xxx.txt", "w",encoding="utf-8") as f:
        f.write(txt)


txt = readPDF(open('xxx.pdf', 'rb'))
saveTxt(txt)

当我添加STRICT = True到 psparser.py 并运行程序时，它返回如下：

Traceback (most recent call last):
  File "F:\Users\IceSun\Documents\py\pdfminer3kTest.py", line 30, in <module>
    txt = readPDF(pdfAhh)

    raise exctype(msg)
