Python请求发送带有数据的图像

Question

I need send from client image and some data (like position of this image ->x, y) to server, but nothing working.

headers = {'Content-Type': 'application/json'}
url = 'http://localhost:9886/images'
payload = {"username" : "Root", "role" : "Admin",
           "image" : open('path_to_file/image.pgm', 'rb')}
payload_json = json.dumps(payload)
r = requests.post(url, data = payload_json, headers = headers)

Is there someone with a straightforward answer?

Answer 1

files = {'upload_file': open('file.txt','rb')}

r = requests.post(url, files=files)
