python - 基于元数据列出 azure blob - python sdk

Question

我正在使用 azure blob 存储 sdk，我希望有办法根据某些元数据信息过滤 blob。

from azure.storage.blob import BlobServiceClient

container_name = 'c1'
blob_service_client = BlobServiceClient.from_connection_string(os.environ['STORAGE_ACCOUNT_CONNECTION_STRING'])
container_client = blob_service_client.get_container_client(container_name)

all_blobs = container_client.list_blobs(include='metadata')

for in in all_blobs:
    print('{}'.format(i.name))

我在该帐户中保存了数千个 blob，我希望在我的应用程序中加快搜索速度 - 有没有办法根据元数据进行过滤？我不想查询所有 blob 并进行列表理解。 - 谢谢!

您的包含内容必须是 BlobProperties 列表:

service_client = BlobServiceClient.from_connection_string(connection_string)
container_client = service_client.get_container_client(container_name)

blob_iter = container_client.list_blobs(name_starts_with=None, include=["metadata"])
for i in blob_iter:
    print(i)
