PyPDF 2解密不起作用 [英] PyPDF 2 Decrypt Not Working

问题描述

当前，我正在使用PyPDF 2作为依赖项.

Currently I am using the PyPDF 2 as a dependency.

我遇到了一些加密文件并已处理 像往常一样(在下面的代码中):

I have encountered some encrypted files and handled them as you normally would (in the following code):

    PDF = PdfFileReader(file(pdf_filepath, 'rb'))
    if PDF.isEncrypted:
        PDF.decrypt("")
        print PDF.getNumPages()

我的文件路径看起来像〜/blah/FDJKL492019 21490，LFS.pdf" PDF.decrypt(")返回1，表示成功.但是当它到达print PDF.getNumPages()时， 仍然会引发错误"PyPDF2.utils.PdfReadError:文件尚未解密".

My filepath looks something like "~/blah/FDJKL492019 21490 ,LFS.pdf" PDF.decrypt("") returns 1, which means it was successful. But when it hits print PDF.getNumPages(), it still raises the error, "PyPDF2.utils.PdfReadError: File has not been decrypted".

如何摆脱这个错误? 我可以通过双击打开PDF文件(默认情况是使用Adobe Reader打开).

How do I get rid of this error? I can open the PDF file just fine by double click (which default-opens with Adobe Reader).

推荐答案

回答我自己的问题: 如果文件名中包含空格，那么即使返回成功代码，PyPDF 2解密功能最终也会失败. 通过PyPDF2运行PDF之前，请在命名PDF时尽量使用下划线.

To Answer My Own Question: If you have ANY spaces in your file name, then PyPDF 2 decrypt function will ultimately fail despite returning a success code. Try to stick to underscores when naming your PDFs before you run them through PyPDF2.

例如，

执行"FDJKL492019_21490_，LFS.pdf"之类的操作，而不是"FDJKL492019 21490，LFS.pdf".

Rather than "FDJKL492019 21490 ,LFS.pdf" do something like "FDJKL492019_21490_,LFS.pdf".
