How do I configure file upload settings in Flask?

To configure file upload settings in Flask, you can set parameters like MAX_CONTENT_LENGTH and ALLOWED_EXTENSIONS in your app's config.

What is MAX_CONTENT_LENGTH and how do I set it?

MAX_CONTENT_LENGTH is a setting that limits the size of uploaded files. You can set it like this: app.config['MAX_CONTENT_LENGTH'] = 16 * 1024 * 1024 for a 16MB limit.

How can I restrict file types for uploads?

You can restrict file types by defining a set of allowed extensions and checking the file's extension before saving it.

Can you show me an example of how to implement this?

Sure! Here's a simple example:

ALLOWED_EXTENSIONS = {'png', 'jpg', 'jpeg', 'gif'}

def allowed_file(filename):
    return '.' in filename and \
           filename.rsplit('.', 1)[1].lower() in ALLOWED_EXTENSIONS
