I don’t think 100-Continue will be the issue here: Requests just ignores it.
What’s likely happening here is that the remote server is sending a 400 Client
Error, but Requests doesn’t see it because it’s busy uploading the data and
eventually the server gets mad and kills the connection to stop more data
arriving. This is a known problem with Requests that comes out of httplib, and
we’re actively working to fix it (by killing httplib).
The only major difference between what Requests sends here and what curl sends
is that curl is adding a Content-Type header to the file that Requests is not.
Otherwise the differences are entirely in headers that should be irrelevant.
You can try changing your code to use `files = {‘aFile’: (‘test.zip’,
open(‘/tmp/test.zip’, ‘rb’), ‘application/octet-stream’)}` (or whatever you
judge the correct content-type of a zip file to be).
