In believing that wsgi.input is a simple file that contains your
upload. It isn't. It is multipart/form-data encoded, to cope with
potentially many files being uploaded in one go, plus assorted other
form fields.

In another post, you have already been shown how to do this. What where
the results? How does your full script look like? How does the form look
like you upload with?
