Generate a fresh jpg file upon user triggering the route in Flask using Ajax

app = Flask(__name__)
@app.route('/' , methods = ['GET', 'POST'])
def index():
    print("hello")
    if request.method == 'GET':
        text = request.args.get("image")
        

        print(text)

        base64_img_bytes = text.encode('utf-8')
        file_name = f"decoded_image_{uuid.uuid4()}.jpeg"
        with open(file_name, 'wb') as file_to_save:
            decoded_image_data = base64.decodebytes(base64_img_bytes)
            file_to_save.write(decoded_image_data)

The code above defines my app.py where an ajax request sends an image captured from the user's camera to the route. The image is encoded and written into a new file for each user. To enable this functionality for multiple users, a unique file name is generated using uuid for each user image.

Every time a user makes a request to the route, a new jpg file will be created and saved locally.

Answer №1

Whenever a user accesses the route, a new jpg file should be generated and saved locally.

To ensure that a unique filename is created each time, you can utilize the uuid module. Begin by adding the following import statement:

import uuid

In place of

with open('decoded_image.jpeg', 'wb') as file_to_save:

you can use

with open('decoded_image_{}.jpeg'.format(uuid.uuid4().hex), 'wb') as file_to_save:
