How to base64 encode a PDF file in Python

How should I base64 encode a PDF file for transport over XML-RPC in Python?

Answer 1

If you don't want to use the xmlrpclib's Binary class, you can just use the .encode() method of strings:

a = open("pdf_reference.pdf", "rb").read().encode("base64")

Answer 2

Actually, after some more digging, it looks like the xmlrpclib module may have the piece I need with it's Binary helper class:

binary_obj = xmlrpclib.Binary( open('foo.pdf').read() )

Here's an example from the Trac XML-RPC documentation

import xmlrpclib 
server = xmlrpclib.ServerProxy("http://athomas:password@localhost:8080/trunk/login/xmlrpc")'WikiStart/', xmlrpclib.Binary(open('').read()))

Answer 3

You can do it with the base64 library, legacy interface.

Answer 4

Looks like you might be able to use the binascii module


Convert binary data to a line of ASCII characters in base64 coding. The return value is the converted line, including a newline char. The length of data should be at most 57 to adhere to the base64 standard.

python - How to handle unicode of an unknown encoding in Django?

I want to save some text to the database using the Django ORM wrappers.
