我其实使用 PyPdf 打开、读写 PDF 文件的内容 。
我使用这些代码线:
from pyPdf import PdfFileWriter, PdfFileReader
pdf = PdfFileReader(file("/myPdfFile.pdf", "w+b"))
content = pdf.getPage(1).extractText()
print content
但它让我回回这个错误 我不明白为什么
File "/usr/local/lib/python2.6/dist-packages/pyPdf/pdf.py", line 374, in __init__
self.read(stream)
File "/usr/local/lib/python2.6/dist-packages/pyPdf/pdf.py", line 702, in read
stream.seek(-1, 2)
IOError: [Errno 22] Invalid argument
谁能帮我?
正如Python docs 中所说,模式 w+b 打开并删除文件到 0 字节,而模式 r+b 打开文件而不缩短。
