如何在Python中对PDF文件进行base64编码

Question

我应该如何对XML文件进行base64编码以便通过Python中的XML-RPC进行传输？

Answer 1

如果您不想使用xmlrpclib的Binary类，则可以使用字符串的.encode（）方法：

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") 
server.wiki.putAttachment('WikiStart/t.py', xmlrpclib.Binary(open('t.py').read())) 

Answer 3

您可以使用base64库 （旧版接口）来实现。

Answer 4

Looks like you might be able to use the binascii module

binascii.b2a_base64(data)

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.
