Python : POST a Multipart-Encoded File - python-requests

Question

Trying to upload a file using requests module, but encountered Internal Server Error Its the same using poster module too:
import requests
url = "abc.com/upload"
querystring = {"ft":"1","fn":"filename"}
payload = ""
files={'file': open(r'Users/.../test.zip', 'rb')}
headers_info = {
'content-type': "multipart/form-data; boundary=---12345",
'x-api-service-version': "1.0",
'connection': "Keep-Alive",
'authorization': "Basic XXXXXXX",
'x-file-format': "decrypted",
'cache-control': "no-cache",
}
response = requests.post(url, data = payload , headers=headers_info , params=querystring , files=files)
print response.status_code
print response.text
I tested the api with POSTMAN (chrome extension to test rest API) and it seems to work fine with postman i get a success response and the file is uploaded.
The postman code for python shows :
import requests
url = "abc.com/upload"
querystring = {"ft":"1","fn":"filename"}
payload = ""
headers = {
'content-type': "multipart/form-data; boundary=---12345",
'accept-encoding': "gzip, deflate",
'x-api-service-version': "1.0",
'connection': "Keep-Alive",
'authorization': "Basic XXXXXXX",
'x-file-format': "decrypted",
'cache-control': "no-cache",
'postman-token': "XXXXXXX"
}
response = requests.request("POST", url, data=payload, headers=headers, params=querystring)
print(response.text)
Any suggestions for the same ? Am I missing something obvious? Thanks for any pointers you can share!

You don't have to specify 'content-type': "multipart/form-data; boundary=---12345", as well as empty data. Try to send request without headers
response = requests.post(url, params=querystring , files=files)
If you fail you might try to add 'authorization': "Basic XXXXXXX", 'postman-token': "XXXXXXX" headers
