How do I configure CORS in a Flask application?

To configure CORS in a Flask application, you can use the Flask-CORS extension. First, install it using pip.

What is the basic setup for Flask-CORS?

After installing Flask-CORS, you can set it up by importing it and initializing it with your Flask app like this:

from flask import Flask
from flask_cors import CORS

app = Flask(__name__)
CORS(app)

Can I allow specific origins only?

Yes, you can specify allowed origins by passing the origins parameter to the CORS function:

CORS(app, origins=['https://example.com'])

What if I want to allow multiple origins?

You can provide a list of origins like this:

CORS(app, origins=['https://example.com', 'https://anotherdomain.com'])
