Python : Passing form-data directly in fast-api with UI

Question

• I am calling a API of OmniDocs, I am able to Add Document using Postman, passing it as form-data.
• When I am trying to do the same in python it is returning Bad request.
• NGOAddDocumentBDO Value

• Postman output

• Using fastapi in python, I am passing 'content-type': 'multipart/form-data', but not able to determine where the request is going wrong, if it is working fine with postman, not able to figure out the problem in fast-api.

Answer 1

Postman on right side should have icon </> to open function Code snippet which can generate code for different languages - even for Python (requests and http.client)

It gives me code which sends file in files=...

import requests

url = "http://10.10.2.41:8003/OmniBook"

payload={'NGOAddDocumentBDO': '<XML>'}
files=[
  ('file',('file',open('/path/to/file','rb'),'application/octet-stream'))
]
headers = {}

response = requests.request("POST", url, headers=headers, data=payload, files=files)

print(response.text)

But I couldn't test it.
