在云存储服务中,Blob(Binary Large Object)是一种用于存储大量非结构化数据(如文本、图像、视频等)的对象。源容器和目标容器都是存储Blob的逻辑单元。复制Blob并异步上传到另一个容器是一个常见的操作,通常用于数据迁移、备份或数据共享。

以下是一个使用Python和Azure Blob Storage SDK进行Blob异步上传的示例代码:
from azure.storage.blob import BlobServiceClient, BlobClient, ContainerClient
import asyncio
async def upload_blob_async(source_blob_client, target_blob_client):
blob_data = source_blob_client.download_blob()
await target_blob_client.upload_blob(blob_data.content_as_bytes(), overwrite=True)
async def main():
source_connection_string = "your_source_connection_string"
target_connection_string = "your_target_connection_string"
source_container_name = "your_source_container_name"
target_container_name = "your_target_container_name"
blob_name = "your_blob_name"
source_blob_service_client = BlobServiceClient.from_connection_string(source_connection_string)
target_blob_service_client = BlobServiceClient.from_connection_string(target_connection_string)
source_container_client = source_blob_service_client.get_container_client(source_container_name)
target_container_client = target_blob_service_client.get_container_client(target_container_name)
source_blob_client = source_container_client.get_blob_client(blob_name)
target_blob_client = target_container_client.get_blob_client(blob_name)
await upload_blob_async(source_blob_client, target_blob_client)
if __name__ == "__main__":
asyncio.run(main())
请注意,以上示例代码和参考链接是基于Azure Blob Storage的,如果你使用的是其他云存储服务,可能需要调整代码和参考链接。
