python - Azure Blob 存储 - 可以列出 blob，但不能删除 blob

Question

我正在尝试从 Azure 容器中删除 blob。我能够连接到它并列出此问题中代码后面的所有 blob:Upload and Delete Azure Storage Blob using azure-storage-blob or azure-storage

CONNECT_STR = "DefaultEndpointsProtocol=https;AccountName=XXX;AccountKey=XXXXXXXXXX;EndpointSuffix=core.windows.net"
CONTAINER_NAME = "containername/"
blob_name = "productionmap/oursoftware/intended_blob_to_use.csv"

container_client = ContainerClient.from_connection_string(conn_str=CONNECT_STR, container_name=CONTAINER_NAME)

# Delete blob
container_client.delete_blob(blob=blob_name)

我能够列出所有的 blob。我尝试使用 for 循环来遍历 blob 并获取要删除的特定 blob:

for x in bloblist:
  if x.name == 'intended_blob_to_use.csv':
    print(x.name)
    container_client.delete_blob(blob=x)

上面的代码能够通过打印获取特定的blob名称，但无法删除它。因此它不应该与我的文件名有关。我收到的错误消息是:

为什么我不能删除它？我通过连接字符串传递 key ，并且该用户在存储上设置了“所有者”。

使用相同的代码从我们的端进行复制后，我们收到了相同的错误。

就像 @Gaurav Mantri 提到的那样，是额外的尾部斜杠导致了错误，这使得它指向不同的路径并导致 BlobNotFound。
