@ markwalker_ Большое спасибо за ваш комментарий. Вот мой ответ. Переменная res
здесь небрежная, поскольку она может быть None
и вызывает ошибку. Позже я добавлю определение исключения для этой проблемы
Поместите private
в settings.py
AWS_DEFAULT_ACL = 'private'
import logging
import boto3
from botocore.exceptions import ClientError
logger = logging.getLogger('django')
def create_presigned_url(bucket_name, object_name, expiration=3600):
"""Generate a presigned URL to share an S3 object
:param bucket_name: string
:param object_name: string
:param expiration: Time in seconds for the presigned URL to remain valid
:return: Presigned URL as string. If error, returns None.
"""
# Generate a presigned URL for the S3 object
s3_client = boto3.client('s3')
try:
response = s3_client.generate_presigned_url('get_object',
Params={'Bucket': bucket_name,
'Key': object_name},
ExpiresIn=expiration)
except ClientError as e:
logging.error(e)
return None
# The response contains the presigned URL
return response
Затем мне нужно override
метод to_representation
class AWSImageField(serializers.ImageField):
def to_representation(self, value):
if not value:
return None
# `media/` is `MEDIA_URL`, but it is being used with `public-config`. I don't want to mess up the common use case
url = create_presigned_url(settings.AWS_STORAGE_BUCKET_NAME, 'media/' + value.name)
if url is not None:
res = requests.get(url)
return res.url
