azure-blob-storage - 无法通过 SAS 使用 azcopy 从一个 blob 到另一个 blob

Question

我有 2 个 Blob 存储，一个在 eastus，一个在 canadaeast，我想将一个 .vhd 从 eastus 复制到 canadaeast。 我去了 eastus，在我想要复制的 blob 上。我打开上下文菜单，单击“生成 SAS”。我生成具有读/写/创建/删除权限的 token 并复制提供的 URL。

我遵循 https://learn.microsoft.com/en-gb/azure/storage/common/storage-use-azcopy-blobs 上的文档

我下载了 azcopy，然后输入:

 azcopy copy "source?SASToken" "destination"

我明白了:

===== RESPONSE ERROR (ServiceCode=ResourceNotFound) =====
Description=The specified resource does not exist.
RequestId:60890ddf-601e-0040-5a4b-62d6ba000000
Time:2019-09-03T11:34:08.5367479Z, Details:
   Code: ResourceNotFound

我生成一个对目标帐户具有读/写/创建/删除权限的 SAS token ，然后键入:

azcopy copy "source?SASToken" "destination?SASToken"

我得到以下结果:

Job a30eaae3-1dfd-f94d-5237-002ababea22c summary

Total Number Of Transfers: 1
Number of Transfers Completed: 0

在生成的日志文件中，我得到

   RESPONSE Status: 400 The value for one of the HTTP headers is not in the correct format.

我陷入困境:我不知道如何将一个 blob 复制到不同位置的另一个 blob，并且我尝试的所有操作都失败了。

我做错了什么？你能帮忙吗？

在存储帐户之间复制 blob 时，应注意当前 azcopy 版本中的以下限制。

• Only accounts that don't have a hierarchical namespace are supported.
• You have to append a SAS token to each source URL. If you provide authorization credentials by using Azure Active Directory (AD), you can omit the SAS token only from the destination URL.
• Premium block blob storage accounts don't support access tiers. Omit the access tier of a blob from the copy operation by setting the s2s-preserve-access-tier to false (For example: --s2s-preserve-access-tier=false).

您可以验证两个存储帐户是否满足上述要求，尤其是第三个。当我将 blob 从 storageV2 复制到 storageV1，然后附加 --s2s-preserve-access-tier=false 时，我可以重现您的问题，它可以工作。
