Скачать или смотреть FastAPI JWT Login for ERP: Secure Auth Flow Explained

Implement a complete login flow for a Dockerized ERP backend with FastAPI, including secure password hashing and JWT issuance. The video covers the POST /api/login endpoint, Pydantic schema validation, fetching users by email, verifying SHA‑256 password hashes, and returning a JWT containing UID and role. It also demonstrates decoding the token payload and explains how this enables future role-based authorization for admin, school, teacher, and student. Finally, the session lifecycle, 422 validation errors, and model lookups per role are shown in Postman for end-to-end testing.

What you’ll learn:

Designing a POST login endpoint with schema validation

Hashing and verifying passwords using SHA‑256

Issuing JWTs (UID + role) and decoding payloads

Role-aware lookups for admin/school/teacher/student

Handling 404 user not found and 422 validation errors

Stack:
FastAPI, Python 3, Pydantic, MariaDB, Postman, JWT (RSA), Docker
