Jython multipart post with commons http-client/core - jython

Question

Hello im trying to send a multipart post request and using jython with commons httpclient 4.3.1.
http_client = DefaultHttpClient()
http_post = HttpPost(url)
bin = FileBody(File(file_name), ContentType.APPLICATION_XML)
me = MultipartEntity()
me.addPart('datei', bin)
http_post.setEntity(me)
print "Executing Post Request:", http_post.getRequestLine()
http_response = http_client.execute(http_post)
result_entity = http_response.getEntity()
return EntityUtils.toString(result_entity)
In my opinion the return value should a str with the content, but it is:
"type 'org.apache.http.conn.BasicManagedEntity'"
Where is my mistake?

I do not know the exact answer to your question. And today I have been trying to make a multipart post work from my jython script for a skiuli project I am working on.
Here is how I was able to do it.
First get ez_setup.py from: http://peak.telecommunity.com/dist/ez_setup.py
Then run jython ez_setup.py from the cmd prompt
Second get poster from: http://atlee.ca/software/poster/dist/0.8.1/
Unzip the file
Then run jython setup.py install
Last you can follow this sample code or see more on the atlee site:
from poster.encode import multipart_encode
from poster.streaminghttp import register_openers
import urllib2
register_openers()
upload_url = "http://your.website.com/upload-multipart.php"
#this will upload a file and a json object
#in php the file is in $_FILES and the json is in $_POST
params = {'file': open("test.txt", "rb"), 'jsonData': '[{"foo":"bar", "foo1":"bar1"}]'}
datagen, headers = multipart_encode(params)
request = urllib2.Request(upload_url, datagen, headers)
result = urllib2.urlopen(request)
print result.read()
I hope this helps someone out there. This example will also work for post multipart in python.
