I'm afraid urllib2 currently doesn't handle this. Neither the lower layer,
httplib. HTTPConnection should be upgraded to handle 'Transfer-Encoding:
chunked', by example. (Chunked responses are handled correctly, but a
request cannot be chunked)
A Q&D approach would be to patch httplib.HTTPConnection.send, to accept a
file or file-like argument. Around line 707, instead of
self.sock.sendall(str):
if hasattr(str, 'read'):
BUFSIZE = 4*1024
while True:
block = str.read(BUFSIZE)
if not block: break
self.sock.sendall(block)
else:
self.sock.sendall(str)
and ensure the Content-Length header is already set, so no attempt is made
to compute len(str)
