Python SDK for the Authlib

AuthLib

A Python authentication library that provides JWT, OAuth2, and API token authentication with PostgreSQL backend. This library is designed for seamless integration with Flask applications and provides a robust set of endpoints and utilities for user management, authentication, and API token handling.

Installation

pip install -e .

Quick Start

from flask import Flask
from authlib import AuthManager

app = Flask(__name__)

auth = AuthManager(
    app=app,
    db_dsn="postgresql://user:pass@localhost/dbname",
    jwt_secret="your-secret-key",
    oauth_config={
        "google": {
            "client_id": "your-client-id",
            "client_secret": "your-client-secret"
        }
    }
)

@app.route("/protected")
@auth.require_auth(roles=["admin"])
def protected_route():
    return "Protected content"

Configuration

Required Parameters

• app: Flask application instance
• db_dsn: PostgreSQL connection string
• jwt_secret: Secret key for JWT signing

Optional Parameters

• oauth_config: Dictionary of OAuth provider configurations (see below)
• token_expiry: JWT token expiry time in seconds (default: 3600)
• refresh_token_expiry: Refresh token expiry time in seconds (default: 2592000)

Example oauth_config:

{
    "google": {
        "client_id": "...",
        "client_secret": "..."
    },
    "github": {
        "client_id": "...",
        "client_secret": "..."
    }
}

API Endpoints

Authentication

• POST /api/v1/users/login - Login with username/password
  • Request: { "username": "string", "password": "string" }
  • Response: { "token": "jwt", "refresh_token": "jwt", "user": { ... } }
• POST /api/v1/users/login/oauth - Get OAuth redirect URL
  • Request: { "provider": "google|github|..." }
  • Response: { "redirect_url": "string" }
• GET /api/v1/users/login/oauth2callback - OAuth callback
  • Query Params: code, state, provider
  • Response: { "token": "jwt", "refresh_token": "jwt", "user": { ... } }
• POST /api/v1/users/token-refresh - Refresh JWT token
  • Request: { "refresh_token": "jwt" }
  • Response: { "token": "jwt", "refresh_token": "jwt" }

User Management

• POST /api/v1/users/register - Register new user
  • Request: { "username": "string", "password": "string", "email": "string", ... }
  • Response: { "user": { ... }, "token": "jwt", "refresh_token": "jwt" }
• GET /api/v1/users/login/profile - Get user profile
  • Auth: Bearer JWT
  • Response: { "user": { ... } }
• GET /api/v1/users/roles - Get available roles
  • Response: [ "admin", "user", ... ]

API Tokens

• POST /api/v1/users/{user}/api-tokens - Create API token
  • Request: { "name": "string", "scopes": [ ... ] }
  • Response: { "token": "string", "id": "uuid", ... }
• GET /api/v1/users/{user}/api-tokens - List API tokens
  • Response: [ { "id": "uuid", "name": "string", ... } ]
• DELETE /api/v1/users/{user}/api-tokens/{token_id} - Delete API token
  • Response: { "success": true }

Authentication Flow

1. Login:
   • User submits credentials to /api/v1/users/login.
   • Receives JWT and refresh token.
2. Token Refresh:
   • Use /api/v1/users/token-refresh with refresh token to get new JWT.
3. OAuth:
   • Get redirect URL from /api/v1/users/login/oauth.
   • Complete OAuth flow via /api/v1/users/login/oauth2callback.
4. Protected Routes:
   • Use @auth.require_auth() decorator to protect Flask routes.

User Object

The user object returned by the API typically includes:

{
  "id": "uuid",
  "username": "string",
  "email": "string",
  "roles": ["user", "admin"],
  "created_at": "timestamp",
  "last_login": "timestamp"
}

Token Management

• JWT: Used for authenticating API requests. Include in Authorization: Bearer <token> header.
• Refresh Token: Used to obtain new JWTs without re-authenticating.
• API Tokens: Long-lived tokens for programmatic access, managed per user.
