如何使用 Powershell 下载文件、修改文件并将其上传到 Azure 文件存储？

Question

我在 Azure 文件共享上有一个文件，我想下载它、修改它，然后使用 Powershell 再次上传它。这是我到目前为止编写的代码，但它不起作用：

$context = New-AzStorageContext -StorageAccountName $storageAccountName -StorageAccountKey $storageAccountKey
$share = Get-AzStorageShare -Name $shareName -Context $context
$client = $share.CloudBlob.OpenRead($filePath)
$file = $client.DownloadText()

不幸的是它给了我一个错误。代码可能有什么问题？

我在 Azure 文件共享上有一个文件，如下所示：

使用 Azure 自动化修改脚本并上传它，您可以制作如下脚本。

$Appid = "789da472-e33e-4de6-bada-XXXXXXX"
$PWord = ConvertTo-SecureString -String "Yig8Q~_R_RPrl_Wrcn2CX5VAsngwR1tXXXXXXX" -AsPlainText -Force
$tenant = "72f988bf-86f1-41af-91ab-2dXXXXXXX"
$Credential = New-Object -TypeName "System.Management.Automation.PSCredential" -ArgumentList $Appid, $PWord

# Authenticate
$null = Add-AzAccount -Credential $Credential -Tenant $tenant -ServicePrincipal

$storageAccountName = "xxxxx"
$storageAccountKey = "euf04t6rJW7z7UKr1VhSlfduHAlouTZ7/rxzzMhmOE7XXXXXXXXXXXXXXX"

# File share information
$shareName = "file1"
$filePath = 'demo.txt'

try {
    # Construct the storage context
    $context = New-AzStorageContext -StorageAccountName $storageAccountName -StorageAccountKey $storageAccountKey

    # Define a temporary directory within the Azure Automation sandbox
    $tempPath = Join-Path $env:TEMP "tempfile1.txt" 

    Write-Output "Share Name: $shareName"
    Write-Output "Temporary Path: $tempPath"

    # Get the file content from the Azure File Share
    Write-Output "Getting file content from Azure File Share..."
    Get-AzStorageFileContent -ShareName $shareName -Path $filePath -Destination $tempPath -Context $context
    Write-Output "File content retrieved and saved to temporary directory."

    # Read and modify the file content
    $fileContent = Get-Content $tempPath
    Write-Output $fileContent
    $newFileContent = $fileContent -replace 'Imran123', 'Khan123'
    $newFileContent | Set-Content $tempPath
    Write-Output $newFileContent

    Set-AzStorageFileContent -ShareName $shareName -Source $tempPath -Path $filePath -Context $context -Force
    Write-Output "Modified file content uploaded."
}
catch {
    Write-Output "An error occurred: $_"
}

# Sign out to avoid potential issues with credentials
Remove-AzAccount -Scope Process 

现在，当我运行上面的脚本时，文件被修改并成功上传到文件共享中，如下所示：

输出：
