How to make a post request that includes open files?

Question

Мy query produces the following error

{"ExportedDataFile":["The ExportedDataFile field is required."]}

import requests

files = {'file': open('33332815-2019-04-191419.xml', 'rb')}
payload = {'ExportedDataFile': files, 'Token': 'test'}
r = requests.post("http://????", data=payload)
print(r.text)

Why are you passing in the `files` dictionary as the `ExportedDataFile` key in the `data` mapping? You need to pass in that dictionary as the `files` argument, possibly with the key in that dictionary set to `ExportedDataFile`, so `files = {'ExportedDataFile': open(...)}`, and `payload = {'Token': 'test'}`, then `requests.post(url, data=payload, files=files)`. See the duplicate. — Martijn Pieters, Apr 19 '19 at 13:00
You passed an open file object in `{'file': ...}`. Files should be passed via `files` argument to `requests.post` presuming that the server on the other end is expecting some multipart MIME document: http://docs.python-requests.org/en/master/api/#requests.request — Iguananaut, Apr 19 '19 at 13:00

As @Martijn Pieters points out, you can post files, like so:

import requests

files = {'ExportedDataFile': open('33332815-2019-04-191419.xml', 'rb')}
payload = {'Token': 'test'}
r = requests.post("http://????", files=files, data=payload)
print(r.text)

Yes, you **can** post a file object, but not in the way the OP is using it. – Martijn Pieters Apr 19 '19 at 13:00
