Question

我这几天一直在努力。使用S3与Django + django-storages和Heroku的静态文件。

首先，我创建一个S3存储桶case 'SELECT_EDGE_OVERRIDE_IDX': return {...state,selectedEdgeOverrideIdx: action.selectedEdgeOverrideIdx}并生成访问密钥（访问密钥ID和秘密访问密钥）。

我安装了4f2xivbz443 https://django-storages.readthedocs.io/en/latest/，并按照有关如何添加和设置Amazon S3的说明进行操作。

当我部署时，我收到此错误：

django-storages

以下是所有代码。

settings.py（最后添加了Amazon S3设置）

           raise error_class(parsed_response, operation_name)

   botocore.exceptions.ClientError: An error occurred (InvalidRequest) when calling the PutObject operation: The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256.

Answer 1

Heroku：S3 / boto3-错误：

请使用AWS4-HMAC-SHA256，对于在django-storages中面临AWS4-HMAC-SHA256错误（图像未加载）的人。

尝试在settings.py中使用此值：

如果使用boto3：

AWS_S3_REGION_NAME = 'us-east-2' #change to your region
AWS_S3_SIGNATURE_VERSION = 's3v4'

如果使用boto：

AWS_S3_HOST = 'us-east-2' #change to your region
S3_USE_SIGV4 = True

Answer 2

使用WhiteNoise提供静态文件时，不应使用S3存储静态文件。（使用S3存储和提供媒体文件很好 - 事实上，鼓励它。）

只需删除此行：

STATICFILES_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'

和这一行

STATIC_URL = 'http://' + AWS_STORAGE_BUCKET_NAME + '.s3.amazonaws.com/'

您可以保留其他设置。

如果您想将WhiteNoise与Cloudfront一起使用，则需要提供说明here。

P.S。在您的Heroku配置变量中，您已经发布了数据库凭据，因此任何人都可以连接到您的数据库。您可以重置here。
