convert curl to requests using multipart/mixed in python

Question

I'm trying to convert the following curl post to a Python request:

curl -k -i -H "Content-Type: multipart/mixed" -X POST --form 
'session.id=e7a29776-5783-49d7-afa0-b0e688096b5e' --form 'ajax=upload' 
--form 'file=@myproject.zip;type=application/zip' --form 'project=MyProject;type/plain' https://localhost:8443/manager

I used curl.trillworks.com to make an auto conversion but it didn't work. I also tried the following:

sessionID = e7a29776-5783-49d7-afa0-b0e688096b5e
project = 'file.zip'
metadata = json.dumps({"documentType":"multipart/mixed"})
files = {
         'meta' : ('', metadata , 'application/zip'),
         'data':(project, 'multipart/mixed', 'application/octet-stream')}
data = {'ajax':'upload','project':'test','session.id':sessionId}
cookie = {'azkaban.browser.session.id':sessionId}
response=requests.post('https://'+azkabanURL+'/manager',
data=data,verify=False,files=files)
print response.text

I got the following error:

<p>Problem accessing /manager. Reason:

Can't figure out what I'm missing here??

Answer 1

I found the answer after trying out some of the examples from requests site and finally it worked.

data = {'ajax':'upload','project':'test','session.id':sessionId}
files  = {'file':('projects.zip',open('projects.zip','rb'),'application/zip')}
response=requests.post('https://'+azkabanURL+'/manager',data=data,verify=False,files=files)
print response.text
print response.status_code

Answer 2

For the future reference I recommend you to check this online tool: http://curl.trillworks.com/ it converts curl to python requests, node and php. It has helped my multiple times.
