Скачать или смотреть Flask JWT Authentication | Protect API Routes with Middleware and Decorators | API Security Part 3

This is Part 3 of the API Security series with Flask. In this tutorial, we secure API endpoints by requiring a JWT token before users can access them. You will learn how to use middleware and decorators to validate tokens and modularize your security logic.

🔑 What you will learn:

Creating a test blueprint for protected routes

Building middleware to check for valid JWT tokens

Restricting access when no token is provided

Logging in and testing tokens in protected routes

Separating JWT checks into a reusable module

Using decorators to enforce route protection
