How can I handle authentication errors in a Flask RESTful API?

You can handle authentication errors in Flask RESTful APIs by using custom error handlers and returning appropriate HTTP status codes.

Can you give me an example of a custom error handler?

Sure! You can create a custom error handler like this:

from flask import Flask, jsonify

app = Flask(__name__)

@app.errorhandler(401)
def unauthorized_error(error):
    return jsonify({'message': 'Unauthorized access'}), 401

What about handling expired tokens?

For expired tokens, you can create another error handler that checks for token validity and returns a 401 status with a specific message.

How do I implement token validation in my API?

You can implement token validation using libraries like PyJWT to decode and verify tokens in your request headers.
