Добился чего-то подобного:
код:
file={'type':(None,'formData','text/plain; charset=utf-8', {'Content-Transfer-Encoding': 'binary','Content-Length': len('formData')}),
'image':('image.jpg',open('noch-gory-priroda-dom_resize.jpg', 'rb'),'multipart/form-data',{'Content-Length': 'need size'})}
На выходе:
