Flask-RESTful - Upload image

The following is enough to save the uploaded file:

from flask import Flask
from flask_restful import Resource, Api, reqparse
import werkzeug

class UploadImage(Resource):
   def post(self):
     parse = reqparse.RequestParser()
     parse.add_argument('file', type=werkzeug.datastructures.FileStorage, location='files')
     args = parse.parse_args()
     image_file = args['file']
     image_file.save("your_file_name.jpg")

class UploadWavAPI(Resource):
    def post(self):
        parse = reqparse.RequestParser()
        parse.add_argument('audio', type=werkzeug.FileStorage, location='files')

        args = parse.parse_args()

        stream = args['audio'].stream
        wav_file = wave.open(stream, 'rb')
        signal = wav_file.readframes(-1)
        signal = np.fromstring(signal, 'Int16')
        fs = wav_file.getframerate()
        wav_file.close()

You should process the stream, if it was a wav, the code above works. For an image, you should store on the database or upload to AWS S3 or Google Storage
