Handle cors di Django Rest Framework

langkah pertama yaitu letakkan middleware di file settings.py di app root

MIDDLEWARE = [
    'corsheaders.middleware.CorsMiddleware', # tambahkan kode ini
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

tambahkan juga settingan untuk cors

# cors
ALLOWED_HOSTS= ['localhost','sub.domain.com']
CORS_ORIGIN_ALLOW_ALL = False
CORS_ORIGIN_WHITELIST = ('https://*.domain.com','https://localhost:3000','https://example.com')

restart server dan coba test di web client
