问题描述

我的目标是检查文件是否存在于 blob 容器的文件夹中。从门户访问存储已关闭,所以这是我所拥有的:

  1. 带有 PowerShell 和 Azure 存储资源管理器的 VM
  2. 文件路径:mycontainer/in/data/documents/
  3. 连接字符串(已修改):BlobEndpoint=https://storagecont01.blob.core.windows.net/;QueueEndpoint=https://storageacont01.queue.core.windows.net/;FileEndpoint=https://storageacont01.file.core.windows.net/;TableEndpoint=https://storageacont01.table.core.windows.net/;SharedAccessSignature=sv=2019-06-00&ss=bxqt&srt=sco&sp=xwlacux&se=2019-06-00T00:00:05Z&st=2019-06-00T01:30:00Z&spr=https&sig=Sz%2zxdadzca1e137zzdzdq131D%21366bpafOrAAdac%3D

我的 AD 帐户无权访问这些文件,但我通过上面的连接字符串通过 Azure 存储帐户成功连接,并且我使用 Azcopy 成功复制了文件

遵循线程如何在 此处列出 Azure 存储容器和 Blob 是我尝试过的(不成功,get-azstorageblob也不起作用):

$ctx = New-AzStorageContext -StorageAccountName "storageacont01"  -sastoken "sv=2019-06-00&ss=bxqt&srt=sco&sp=xwlacux&se=2019-06-00T00:00:05Z&st=2019-06-00T01:30:00Z&spr=https&sig=Sz%2zxdadzca1e137zzdzdq131D%21366bpafOrAAdac%3D"

get-azstoragecontainer -container "mycontainer" -Context $ctx -Debug

我的问题是:

  1. 难道我做错了什么?
  2. 是否有可能,给我的连接字符串会限制来自 PowerShell 的访问?

UPD:帐户种类 StorageV2(通用 v2)

这是调试输出:

解决方案


显然问题是客户端(VM)端没有满足最低 TLS 要求。以下代码更改了当前 PowerShell 会话的 TLS:

$TLS12Protocol = [System.Net.SecurityProtocolType] 'Ssl3 , Tls12'
[System.Net.ServicePointManager]::SecurityProtocol = $TLS12Protocol

根据 Microsoft 的文档:https ://docs.microsoft.com/en-us/azure/databox-online/azure-stack-edge-gpu-configure-tls-settings
