  • @between(field, min, max, include_min=True, include_max=True, annotation=Number, allow_none=False)
  • @rsa_decrypt(field, private_key_instance)

  • @cache(key, expire=None, cache_name="default", get_from_cache=True, set_to_cache=True)
  • @safe_apiview(get_client_rsa_publickey, **kwargs)

Note:

  • @apiview
    1. apiview = Apiview(SimpleJsonPacker())
  • @safe_apiview(...)
    1. Requires django_middleware_global_request, see django_middleware_global_request's usage at https://pypi.org/project/django-middleware-global-request/.
    2. Requires server rsa settings: RSA_PRIVATEKEY_STRING, RSA_PRIVATEKEY (load RSA_PRIVATEKEY_STRING as RsaKey)
    3. Callback function get_client_rsa_publickey defines: def get_client_rsa_publickey(client_id): pass
    4. kwargs:
      1. client_id_fieldname = "clientId"
      2. client_rsa_publickey_fieldname = "CLIENT_RSA_PUBLICKEY"
      3. result_encoder = cipherutils.SafeBase64Encoder()
      4. server_rsa_privatekey_filedname = RSA_PRIVATEKEY
      5. encrypted_password_fieldname = encryptedPassword
      6. encrypted_data_fieldname = encryptedData
      7. packer_class = SafeJsonResultPacker
      8. password_length = 32
  • @cache(...)
    1. Optional setting: DJANGO_APIVIEW_DISABLE_CACHE_HEADER_NAME = "HTTP_DISABLE_CACHE"
    2. Optional setting: DJANGO_APIVIEW_DEFAULT_CACHE_EXPIRE = None

Usage

Note:

  • Apiview always set csrf_exempt=True.
  • @apiview or @safe_apiview decorator must be the first decorator.
