Flask-RESTful - Upload image

The following is enough to save the uploaded file:

from flask import Flaskfrom flask_restful import Resource, Api, reqparseimport werkzeugclass 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

Something on the lines of the following code should help.

 @app.route('/upload', methods=['GET', 'POST']) def upload():    if request.method == 'POST':        file = request.files['file']        extension = os.path.splitext(file.filename)[1]        f_name = str(uuid.uuid4()) + extension        file.save(os.path.join(app.config['UPLOAD_FOLDER'], f_name))        return json.dumps({'filename':f_name})
