python - 使用 pyPdf 打开 pdf url

Question

我如何从 url 而不是从磁盘打开 pdf

有点像

input1 = PdfFileReader(file("http://example.com/a.pdf", "rb"))

我想从 Web 打开多个文件并下载所有文件的合并。

Answer 1

我认为urllib2会得到你想要的。

from urllib2 import Request, urlopen
from pyPdf import PdfFileWriter, PdfFileReader
from StringIO import StringIO

url = "http://www.silicontao.com/ProgrammingGuide/other/beejnet.pdf"
writer = PdfFileWriter()

remoteFile = urlopen(Request(url)).read()
memoryFile = StringIO(remoteFile)
pdfFile = PdfFileReader(memoryFile)

for pageNum in xrange(pdfFile.getNumPages()):
        currentPage = pdfFile.getPage(pageNum)
        #currentPage.mergePage(watermark.getPage(0))
        writer.addPage(currentPage)


outputStream = open("output.pdf","wb")
writer.write(outputStream)
outputStream.close()
