使用 django-storages 在 google 云存储中上传文件时出现 404

Question

当使用 django-storages 库将文件上传到 google 云时，我得到

NotFound at /accounts/profile/1/edit/
404 POST https://storage.googleapis.com/upload/storage/v1/b/moneygame-42/o?uploadType=multipart: ('Request failed with status code', 404, 'Expected one of', <HTTPStatus.OK: 200>)

这是我在 settings.py 中的代码：

DEFAULT_FILE_STORAGE = 'storages.backends.gcloud.GoogleCloudStorage'
GS_PROJECT_ID = GS_BUCKET_NAME = 'moneygame-42'

GS_CREDENTIALS = service_account.Credentials.from_service_account_file(
    "moneygame-42-1fa2467e74eb.json"
)

这里是错误：

Answer 1

经过一番试验，我发现桶名应该包含.appspot.com部分。这是我的新设置：

DEFAULT_FILE_STORAGE = 'storages.backends.gcloud.GoogleCloudStorage'
GS_PROJECT_ID = 'moneygame-42'
GS_BUCKET_NAME = 'moneygame-42.appspot.com'

GS_CREDENTIALS = service_account.Credentials.from_service_account_file(
    "moneygame-42-1fa2467e74eb.json"
)
