How can I implement authentication in Flask microservices?

You can implement authentication in Flask microservices using JWT (JSON Web Tokens) for secure token-based authentication.

What libraries do I need to use for JWT in Flask?

You can use libraries like Flask-JWT-Extended or PyJWT to handle JWT in your Flask application.

Can you provide a code example for setting up JWT?

Sure! Here's a simple example:

from flask import Flask, jsonify, request
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)

How do I secure my microservices with this setup?

You can secure your microservices by requiring the JWT token in the headers of your requests and validating it in each service.
