Handle file from WSGI request

Question

What is a good way to handle a file that has been uploaded through a WSGI POST request?

More info

So far, I'm able to read the raw POST data from environ[wsgi.input]. At this point the issue I am having is that the information associated with the file and the file itself are jammned together into one string:

'------WebKitFormBoundarymzmB1wyHKjyqZrDm
Content-Disposition: form-data; name="file"; filename="new file.wav"
Content-Type: audio/wav

THIS IS THE CONTENT
THIS IS THE CONTENT
THIS IS THE CONTENT
THIS IS THE CONTENT
THIS IS THE CONTENT

------WebKitFormBoundarymzmB1wyHKjyqZrDm--
'

Is there a library in python I should be using to handle information more cleanly? Ultimately, I'd like to take the file contents and then turn around and upload to Amazon S3.

Usually you want much more abstraction than raw WSGI. Consider frameworks that run on WSGI.

You can use cgi.FieldStorage.

import cgi
form = cgi.FieldStorage(fp=environ['wsgi.input'], environ=environ)
f = form['file'].file
# You can use `f` as a file object: f.read(...)
