DRF with JWT

Authenticate with JWT!

I. Prerequisites

1. Install REST framework JWT Auth package

• Package official documentation: https://jpadilla.github.io/django-rest-framework-jwt/

pip install djangorestframework-jwt

2. Change settings.py configuration

(1) Change REST_FRAMEWORK configuration

• Add content below the REST_FRAMEWORK configuration variable

• Means setting authentication method to JSONWebTokenAuthentication method

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': [
        'rest_framework_jwt.authentication.JSONWebTokenAuthentication',  # Replace from Token
        # 'rest_framework.authentication.TokenAuthentication',
    ]
}

(2) Add REST_USE_JWT configuration

• Add configuration for DRF auth to use JWT

REST_USE_JWT = True

(3) Add JWT_AUTH configuration

• JWT related information configuration (example)

• For details, refer to official documentation (https://jpadilla.github.io/django-rest-framework-jwt/)

import datetime
JWT_AUTH = {
    'JWT_SECRET_KEY': SECRET_KEY,
    'JWT_ALGORITHM': 'HS256',
    'JWT_ALLOW_REFRESH': True,
  # Token valid for 1 week
    'JWT_EXPIRATION_DELTA': datetime.timedelta(days=7),
  # Renewed every 28 days (when extending validity period)
    'JWT_REFRESH_EXPIRATION_DELTA': datetime.timedelta(days=28),
}

II. All changes

settings.py

# DRF auth settings
REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': [
        'rest_framework_jwt.authentication.JSONWebTokenAuthentication',  # Replace from Token
        # 'rest_framework.authentication.TokenAuthentication',
    ]
}

# Configuration for DRF auth to use JWT
REST_USE_JWT = True

# JWT Token related information configuration: What information to include
import datetime
JWT_AUTH = {
    'JWT_SECRET_KEY': SECRET_KEY,
    'JWT_ALGORITHM': 'HS256',
    'JWT_ALLOW_REFRESH': True,
  # Token valid for 1 week
    'JWT_EXPIRATION_DELTA': datetime.timedelta(days=7),
  # Renewed every 28 days (when extending validity period)
    'JWT_REFRESH_EXPIRATION_DELTA': datetime.timedelta(days=28),
}
