import PyPDF2
minutesFile = open('meetingminutes.pdf', 'rb')
pdfReader = PyPDF2.PdfFileReader(minutesFile)
minutesFirstPage = pdfReader.getPage(0)
pdfWatermarkReader = PyPDF2.PdfFileReader(open('watermark.pdf', 'rb'))
minutesFirstPage.mergePage(pdfWatermarkReader.getPage(0))
pdfWriter = PyPDF2.PdfFileWriter()
pdfWriter.addPage(minutesFirstPage)

for pageNum in range(1, pdfReader.numPages):
    pageObj = pdfReader.getPage(pageNum)
    pdfWriter.addPage(pageObj)
resultPdfFile = open('watermarkedCover.pdf', 'wb')
pdfWriter.write(resultPdfFile)
print(minutesFile.close())
print(resultPdfFile.close())

请问大佬，这个文档生成只会对第一页添加水印，如果我想将每个页面都添加我该添加什么代码呀

从你们的描述和代码看，应该在for循环里面补充一句pageObj.mergePage(pdfWatermarkReader.getPage(0))

也就是变成

1. 
   
2. import PyPDF2
   
3. minutesFile = open('meetingminutes.pdf', 'rb')
   
4. pdfReader = PyPDF2.PdfFileReader(minutesFile)
   
5. minutesFirstPage = pdfReader.getPage(0)
   
6. pdfWatermarkReader = PyPDF2.PdfFileReader(open('watermark.pdf', 'rb'))
   
7. minutesFirstPage.mergePage(pdfWatermarkReader.getPage(0))
   
8. pdfWriter = PyPDF2.PdfFileWriter()
   
9. pdfWriter.addPage(minutesFirstPage)
   
10. 
    
11. for pageNum in range(1, pdfReader.numPages):
    
12.     pageObj = pdfReader.getPage(pageNum)
    
13.     pageObj.mergePage(pdfWatermarkReader.getPage(0))
    
14.     pdfWriter.addPage(pageObj)
    
15. resultPdfFile = open('watermarkedCover.pdf', 'wb')
    
16. pdfWriter.write(resultPdfFile)
    
17. print(minutesFile.close())
    
18. print(resultPdfFile.close())
