Python3 flask receive file and send it to another api

python api file flask request

I got code:400 as return or it shows the file I upload is empty, I found requests in flask is a little bit tricky.change this

r1 = requests.request("POST", url1, files={'file':request.files['file']}, headers=headers)

into:

file = request.files['file']r1 = requests.post(url1, files={'file':(file.filename, file.stream, file.content_type, file.headers)})
