Question

I uploaded zip folder using file input,but when i check if this zip is valid or not;the result was:is not a valid pkzip file,i don’t know what is the specification for valid pkzip.
I used this code to check:

form = cgi.FieldStorage() 
file_upload = form['file[]']
if zipfile.is_zipfile(file_upload.filename):
    print "%s is a valid pkzip file" % file_upload.filename
else:
    print "%s is not a valid pkzip file" % file_upload.filename

I don’t know why?for example when i upload test.zip,the o/p will be:
test.zip is not a valid pkzip file,I need a help.Thanks

Answer 1

zipfile.is_zipfile takes a path to a file or a file-like object. You’re passing it neither, so it fails.

Ask it about file_upload.file instead.
