Python 2.6 - Upload zip file - Poster 0.4

Question

Hi Folks,

I came here via this question: http://stackoverflow.com/questions/68477/send-file-using-post-from-a-python-script

And by and large it's what I need, plus some additional.

Besides the zipfile som additional information is needed and the POST_DATA looks something like this:

POSTDATA =-----------------------------293432744627532
Content-Disposition: form-data; name="categoryID"

1
-----------------------------293432744627532
Content-Disposition: form-data; name="cID"

-3
-----------------------------293432744627532
Content-Disposition: form-data; name="FileType"

zip
-----------------------------293432744627532
Content-Disposition: form-data; name="name"

Kylie Minogue
-----------------------------293432744627532
Content-Disposition: form-data; name="file1"; filename="At the Beach x8-8283.zip"
Content-Type: application/x-zip-compressed

PK........................

Is this somehow possible with the poster 0.4 module (and before you ask, yes, I'm fairly new to Python...)

Kind regards, Brian K. Andersen

Poster has basic and advanced multipart support.
You may try something like this (modified from poster documentation):

# test_client.py
from poster.encode import multipart_encode
from poster.streaminghttp import register_openers
import urllib2

# Register the streaming http handlers with urllib2
register_openers()

# headers contains the necessary Content-Type and Content-Length
# datagen is a generator object that yields the encoded parameters
datagen, headers = multipart_encode({
    'categoryID' : 1,
    'cID'        : -3,
    'FileType'   : 'zip',
    'name'       : 'Kylie Minogue',
    'file1'      : open('At the Beach x8-8283.zip')
})

# Create the Request object
request = urllib2.Request("http://localhost:5000/upload_data", datagen, headers)

# Actually do the request, and get the response
print urllib2.urlopen(request).read()
