读取pdf文件获取文件信息，代码如下：

#!/usr/local/python3/bin/python3
# -*- coding: utf-8 -*
from PyPDF2 import PdfFileWriter, PdfFileReader

output = PdfFileWriter()
input1 = PdfFileReader(open("/data/wwwroot/default/asset/bfw.pdf", "rb"))

# print document info
print(input1.getDocumentInfo())

# print how many pages input1 has:
print ("pdf_document.pdf has %d pages." % input1.getNumPages())

# print page content
page_content = input1.getPage(0).extractText()
print( page_content )

# add page 1 from input1 to output document, unchanged
output.addPage(input1.getPage(0))

# add page 2 from input1, but rotated clockwise 90 degrees
#output.addPage(input1.getPage(1).rotateClockwise(90))

# finally, write "output" to document-output.pdf
outputStream = open("/data/wwwroot/default/Data/PyPDF2-output.pdf", "wb")
output.write(outputStream)
