Question

我在创建PDF时遇到问题。

首先，我将PdfFileReader的源pdf打开并获取第一页，然后，将第一页添加到输出文件（PDFFileWriter）的页面列表中。

但是当我去检查输出文件时，它只包含一个空白页，这是我的代码：

with open('pdf/'+articolo['itemfilename'], 'rb') as infile:
        reader = PdfFileReader(infile)
        writer = PdfFileWriter() #writer.addPage(reader.getPage(i))
        if articolo['copertina'] == 1:    #this is just a check it works I verified
            writer.addPage(reader.getPage(0))
with open('extracted/'+articolo['itemfilename'], 'wb') as outfile:
    writer.write(outfile)

我已经与调试器一起检查了程序是否连接了代码的每一行，所以一切都应该没事。

如果您有任何疑问，请告诉我。

看起来像这段代码：

with open('extracted/'+articolo['itemfilename'], 'wb') as outfile:
    writer.write(outfile)

应在第一个缩进块内缩进，如下所示：

with open('pdf/'+articolo['itemfilename'], 'rb') as infile:
    reader = PdfFileReader(infile)
    writer = PdfFileWriter() #writer.addPage(reader.getPage(i))
    if articolo['copertina'] == 1:    #this is just a check it works I verified
        writer.addPage(reader.getPage(0))
    with open('extracted/'+articolo['itemfilename'], 'wb') as outfile:
        writer.write(outfile)

这对我有用。

尝试提取第一页时，PyPDF2返回空白页
