How can I implement authentication in a Flask API?

You can implement authentication in a Flask API using Flask-Login or Flask-JWT-Extended. Which one would you prefer?

I think I'll go with Flask-JWT-Extended. How do I set it up?

First, install the package using pip. Then, you can set up JWT by initializing it in your Flask app and creating a login route.

Can you show me an example of the login route?

Sure! Here's a simple example:

from flask import Flask, request, jsonify
from flask_jwt_extended import JWTManager, create_access_token

app = Flask(__name__)
app.config['JWT_SECRET_KEY'] = 'your_secret_key'
jwt = JWTManager(app)

@app.route('/login', methods=['POST'])
def login():
    username = request.json.get('username')
    password = request.json.get('password')
    # Verify username and password
    access_token = create_access_token(identity=username)
    return jsonify(access_token=access_token)
