我想複製blob形式一個存儲帳戶到另一個，根據職位here我能夠生成shared access signature (SAS)爲x-ms-copy-source。現在我的問題是我無法通過身份驗證副本blob操作它說「AuthenticationFailedServer failed to authenticate the request」。Azure SAS令牌複製blob操作問題
我使用下面的代碼來生成SAS令牌以及複製blob的身份驗證簽名。有人可以幫助我在修復的問題

一個問題我在你的代碼中看到的是，您使用的是這兩個源和目標帳戶相同的密鑰（'$ account_key'）。 –
@GauravMantri我用'$ source_account_key'和'$ destination_account_key'修改了帖子中的代碼。它仍然無法驗證 – MSA
還有一件事我注意到了。在你的請求標題中，你將'Content-Length'標題的值設置爲'0'（這是正確的），但是你不會在'$ arraysign []'中將這個值保留爲空。你可以試着把這裏的值設置爲'0'，然後重試你的請求嗎？ –
