Image upload issue - Python

Developer help
6

For future reference, this codes works for me:

import requests # pip install requests
import jwt	# pip install pyjwt
from datetime import datetime as date

# Admin API key goes here
key = ''

# Split the key into ID and SECRET
id, secret = key.split(':')

# Prepare header and payload
iat = int(date.now().timestamp())

header = {'alg': 'HS256', 'typ': 'JWT', 'kid': id}
payload = {
    'iat': iat,
    'exp': iat + 5 * 60,
    'aud': '/admin/'
}

# Create the token (including decoding secret)
token = jwt.encode(payload, bytes.fromhex(secret), algorithm='HS256', headers=header)

# Make an authenticated request to create a post

url = 'https://ghost.test.com/ghost/api/admin/images/upload/'
headers = {'Authorization': 'Ghost {}'.format(token)}

with open("test.jpg", "rb") as file:
	files = {'file': ('test.jpg', file, 'image/jpeg')}
	r = requests.post(url, files=files, headers=headers)

print(r.json())

It seems to be important to explicitely set the MIME type, as to image/jpeg in this example. I still had to install the sharp image processing library to make upload with python work.
