Hi! This is my first posting ever on this site. I need to upload a simple text file to Internet servers. With "curl" the operation goes smoothly, both with http and https protocols, both up/downloads. With urllib3 and other TCP-IP handlers the generated header for 'Content-Length' contains a wrong file length indication (log verification with TCPDUMP), the file is not uploaded, the servers return different error messages.

On the contrary, urllib3 file downloads do work, also with authentication.

code example
headers = {'authorization': 'Basic ==codeduserpwd=='}
resp = http_client.request('PUT',
                           'https://webserver.com',
                           headers=headers,
                           fields={'whatfile': (filename, file_data)}
                           )

In addition, in the documentation I still haven't figured out what 'whatfile' (or any of the other keywords used there) actually is. Is this a keyword (where is the list of all allowed kwds?), the source file, the target file, or what else?? How does the function behaviour change depending on that indication?

Thankful for your support!

Is your question about urllib3?
This bug tracker is about python itself.
urllbib3 should be discussed here: https://github.com/shazow/urllib3

Yes, this would appear to be both 3rd party and a support request rather than a bug report.  Gianguido: please work with the urllib3 community, or post to the python-list mailing list.  If you identify an actual bug in Python itself, you can come back here to report it.
