如何使用python sdk将blob上传至带子目录的azure存储容器？

Question

我一直在关注这篇文章。Quickstart: 用Python v12 SDK管理blob 和文件 ContainerClient.upload_blob

这是上传一个blob的片段，用这个目录结构。testcontainer / backup / HelloWorld.cab

bsc = BlobServiceClient.from_connection_string('<connection-string>')
cc = bsc.get_container_client('testcontainer')
cc.upload_blob(name='testcontainer/backup/HelloWorld.cab', data=open(r"\\network\path\to\backup\HelloWorld.cab", 'rb').read())

但我得到了以下错误。有什么想法，我做错了什么？

azure.storage.blob._generated.models._models_py3.StorageErrorException: Operation returned an invalid status 'The specifed resource name contains invalid characters.'

During handling of the above exception, another exception occurred:

注意：我还看到了这个 回答 对于这个问题。Microsoft Azure: 如何在blob容器中创建子目录？

Answer 1

如果我使用无效的资源名，我能够重现这个问题 (这就是错误信息所告诉你的)。

例如，如果我使用 testcontainer 作为我的blob容器名称（这是正确的），我能够上传blob。

但是如果我使用 testContainer 作为我的blob容器名称（无效，注意 "C "的大写字母），我得到了和你一样的错误。

请检查blob容器和blob的名称。关于blob资源的命名约定，请参考这个链接。https:/docs.microsoft.comen-usrestapistorageservicesnaming and-referencing-containers--blobs--and-metadata..
