Read multipart/form-data post request with Flask

Question

I am writing a server in python using Flask. And I know I am going to receive a request that it's type is multipart. These are the requests headers I receive from the post request:

Transfer-Encoding: chunked

Content-Length:

X-Data-Length: 8010

Host: ******

Content-Type: multipart/form-data; boundary=********

*This is how I receive the request:

@app.route('/***', methods == ['POST'])
    def some_function():
        print request.headers
        mp_data = decoder.MultipartDecoder.from_response(request)

        for part in multipart_data.parts:
            print(part.content)
            print(part.headers)

How am I supposed to retrieve the file sent to me in that request? I have tried using request-toolbelt MultipartDecoder but got lost trying to do so.

Any help solving this would be appreciated.

If you mean to retrieve the file send from the client, you can use request.files, it's a dict that maps the name of upload field (<input type="file">) with the file object.

Yes, I am trying to retrieve a photo sent to me. The photo is sent as an np array, which is encoded as a multipart form-data. I tried what you suggested but it didn't work. – Yossi Khasidashvili Sep 27 '18 at 08:47

I am using an external service so I don't know how it builds the request. – Yossi Khasidashvili Sep 27 '18 at 10:05
