Я узнал о Django API REST и реализовал проект quickstart (https://www.django-rest-framework.org/tutorial/quickstart /).
Локально это работает нормально, но я хотел бы использовать API с Postman, но это не работает

Я получил 401 несанкционированную ошибку, я пытаюсь добавить ключ DEFAULT_AUTHENTICATION_CLASSES в settings.py но доза не работает ни

settings.py

 INSTALLED_APPS = [
    'rest_framework',
    'rest_framework.authtoken',
]

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.TokenAuthentication',
        'rest_framework.authentication.SessionAuthentication',
    ),
    'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
    'PAGE_SIZE': 10
}

более того, у меня огромная обратная трассировка в терминале при сохранении проектов (ниже), даже если py manage.py runserver работает

Ответ №1:

Сначала вам нужно будет создать токен для пользователя, от имени которого вы пытаетесь войти в систему.

 from rest_framework.authtoken.models import Token

token = Token.objects.create(user=...)
print(token.key)

Затем вы хотите включить этот токен в заголовок вашего URL

 curl -X GET http://127.0.0.1:8000/api/example/ -H 'Authorization: Token 9944b09199c62bcf9418ad846dd0e4bbdfc6ee4b'

Вот некоторая документация, просмотренная в разделе TokenAuthentication.
https://www.django-rest-framework.org/api-guide/authentication /

В post man вы можете просто щелкнуть поле заголовка и ввести там свой токен. Это должно аутентифицировать вас, вам просто нужно сначала сгенерировать токен для вашего пользователя.

Вот ссылка на некоторую документацию о том, как работать с распространенными типами аутентификации с postman. https://learning.postman.com/docs/sending-requests/authorization/#basic-auth

Ответ №2:

Попробуйте это.

 python3 manage.py migrate

1. хорошо, это работает. Не знаю, почему это не было точно указано в руководстве…

2. django-rest-framework.org/api-guide/authentication/…

3. надеюсь, это поможет. ps: можете ли вы пометить вопрос как решенный / проголосовать за ответ
