How to send an image that was sent with a post request to a model for prediction

@app.route('/', methods = ['POST'])
def predict():
    if request.method == 'POST':
        base64img = request.get_json()['img'].encode('utf-8')

        img = base64.b64decode(base64img)
        with open('imgtemp.png', 'wb') as f:
            f.write(img)

        img = cv2.imread('imgtemp.png', 1)
    
        img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)

        payload = {
            'instances': [{'input_image': img.tolist()}]
        }

        r = requests.post(url, json = payload)
        pred = json.loads(r.content.decode('utf-8'))

        return pred
