我正在尝试使用Azure存储Get Container Properties REST API。我按照“Authentication for the Azure Storage Services”为请求构建授权标头。这是我使用的PowerShell脚本。如何构建Azure存储的授权标头获取容器属性REST API

$StorageAccount = "<Storage Account Name>" 
$Key = "<Storage Account Key>" 
$resource = "<Container Name>" 

$sharedKey = [System.Convert]::FromBase64String($Key) 
$date = [System.DateTime]::UtcNow.ToString("R") 

$stringToSign = "GET`n`n`n`n`n`n`n`n`n`n`n`nx-ms-date:$date`nx-ms-version:2009-09-19`n/$StorageAccount/$resource`nrestype:container" 

$hasher = New-Object System.Security.Cryptography.HMACSHA256 
$hasher.Key = $sharedKey 

$signedSignature = [System.Convert]::ToBase64String($hasher.ComputeHash([System.Text.Encoding]::UTF8.GetBytes($stringToSign))) 

$authHeader = "SharedKey ${StorageAccount}:$signedSignature" 

$headers = @{"x-ms-date"=$date 
      "x-ms-version"="2009-09-19" 
      "Authorization"=$authHeader} 

$container = Invoke-RestMethod -method GET ` 
      -Uri "https://$StorageAccount.blob.core.windows.net/$resource?restype=container" ` 
      -Headers $headers 

从上面的脚本中,我得到身份验证失败的错误。授权标头未正确形成。

关于如何解决这个问题的任何想法?

嗯,我犯了一个非常愚蠢的错误。在我的Invoke-RestMethod的URI中,$resource?restype被PowerShell识别为一个变量。由于它没有定义,所以URI变成https://$StorageAccount.blob.core.windows.net/=container。因此,认证总是失败。连接URI将解决问题。

$URI = "https://$StorageAccount.blob.core.windows.net/$resource"+"?restype=container" 
$container = Invoke-RestMethod -method GET -Uri $URI -Headers $headers
