從VSTS構建時如何將參數傳遞給PowerShell腳本

Question

我正在運行以下PowerShell腳本，將csv文件數據部署到Azure表存儲中。 但是下面的參數對於azure中的不同環境是不同的。假設下面的腳本可以部署到任何環境，但是下面的參數會根據環境而有所不同，所以我想在從運行時將下面的參數傳遞給腳本VSTS中的PowerShell任務。如何完成任務。請幫我解決這個問題。

**$subscriptionName = "Tech Enabled Solutions"
$resourceGroupName = "abc"
$storageAccountName = "defghi"
$location = "North Central US, South Central US"
$StorageAccountKey = "12345678"**

PowerShell腳本：

   function Add-Entity()
{
 [CmdletBinding()]

 param
 (
 $table, 
 [string] $partitionKey, 
 [string] $RowKey, 
 [string] $Label_Usage,
 [string] $Label_Value,
 [string] $Usage_Location,
 [string] $subscriptionName,
 [string] $resourceGroupName,
 [string] $storageAccountName,
 [string] $location,
 [string] $StorageAccountKey
)

 $entity = New-Object -TypeName Microsoft.WindowsAzure.Storage.Table.DynamicTableEntity -ArgumentList $partitionKey, $rowKey 
 $entity.Properties.Add("Label_Value",$Label_Value)
 $entity.Properties.Add("Label_Usage",$Label_Usage)
 $entity.Properties.Add("Usage_Location",$Usage_Location)
 $result = $table.CloudTable.Execute([Microsoft.WindowsAzure.Storage.Table.TableOperation]::InsertOrReplace($entity))
}
$tableName = "sampletable"

# Get a storage context
$ctx = New-AzureStorageContext $StorageAccountName $StorageAccountKey

# Get a reference to the table
$table = Get-AzureStorageTable -Name $tableName -Context $ctx -ErrorAction Ignore
$csv = Import-CSV "d:\a\1\s\DeploymentScripts\sampletable.csv"

ForEach ($line in $csv)
{
 Add-Entity -Table $table -partitionKey $line.partitionkey -rowKey $line.RowKey -Label_Usage $line.Label_Usage -Label_Value $line.Label_Value -Usage_Location $line.Usage_Location

}

您需要使用參數文本框將參數傳遞到腳本（內聯或腳本文件）中。

您的腳本將需要如下所示：

param (
    [string] $table, 
    [string] $partitionKey, 
    [string] $RowKey, 
    [string] $Label_Usage,
    [string] $Label_Value,
    [string] $Usage_Location,
    [string] $subscriptionName,
    [string] $resourceGroupName,
    [string] $storageAccountName,
    [string] $location,
    [string] $StorageAccountKey
)

    $entity = New-Object -TypeName Microsoft.WindowsAzure.Storage.Table.DynamicTableEntity -ArgumentList $partitionKey, $rowKey 
    $entity.Properties.Add("Label_Value",$Label_Value)
    $entity.Properties.Add("Label_Usage",$Label_Usage)
    $entity.Properties.Add("Usage_Location",$Usage_Location)
    $result = $table.CloudTable.Execute([Microsoft.WindowsAzure.Storage.Table.TableOperation]::InsertOrReplace($entity))
    $tableName = "sampletable"

    # Get a storage context
    $ctx = New-AzureStorageContext $StorageAccountName $StorageAccountKey

    # Get a reference to the table
    $table = Get-AzureStorageTable -Name $tableName -Context $ctx -ErrorAction Ignore
    $csv = Import-CSV "d:\a\1\s\DeploymentScripts\sampletable.csv"

    ForEach ($line in $csv)
    {
        Add-Entity -Table $table -partitionKey $line.partitionkey -rowKey $line.RowKey -Label_Usage $line.Label_Usage -Label_Value $line.Label_Value -Usage_Location $line.Usage_Location
    }

您的每個變量都將需要默認設置或作為參數傳遞。 在您的示例中，您將在文本框中看起來類似於以下內容：

-subscriptionName "Tech Enabled Solutions" -$resourceGroupName "abc" -storageAccountName "defghi" -location "North Central US, South Central US" -StorageAccountKey "12345678

該框期望您輸入的參數與從命令行調用PowerShell腳本時輸入的參數完全相同。

您的腳本中未使用某些參數，例如$subscriptionName ， $resourceGroupName ，您可以檢查是否需要它們。

請參考以下代碼以添加參數：

param(
[string] $subscriptionName,
 [string] $resourceGroupName,
 [string] $storageAccountName,
 [string] $location,
 [string] $StorageAccountKey
)
function Add-Entity()
{
 [CmdletBinding()]

 param
 (
 $table, 
 [string] $partitionKey, 
 [string] $RowKey, 
 [string] $Label_Usage,
 [string] $Label_Value,
 [string] $Usage_Location
)

 $entity = New-Object -TypeName Microsoft.WindowsAzure.Storage.Table.DynamicTableEntity -ArgumentList $partitionKey, $rowKey 
 $entity.Properties.Add("Label_Value",$Label_Value)
 $entity.Properties.Add("Label_Usage",$Label_Usage)
 $entity.Properties.Add("Usage_Location",$Usage_Location)
 $result = $table.CloudTable.Execute([Microsoft.WindowsAzure.Storage.Table.TableOperation]::InsertOrReplace($entity))
}
$tableName = "sampletable"

# Get a storage context
$ctx = New-AzureStorageContext $storageAccountName $StorageAccountKey

# Get a reference to the table
$table = Get-AzureStorageTable -Name $tableName -Context $ctx -ErrorAction Ignore
$csv = Import-CSV "d:\a\1\s\DeploymentScripts\sampletable.csv"

ForEach ($line in $csv)
{
 Add-Entity -Table $table -partitionKey $line.partitionkey -rowKey $line.RowKey -Label_Usage $line.Label_Usage -Label_Value $line.Label_Value -Usage_Location $line.Usage_Location

}

在PowerShell任務中指定參數的值（“參數”輸入框）

-subscriptionName "Tech Enabled Solutions" -resourceGroupName "abc" -storageAccountName "defghi" -location "North Central US, South Central US" -StorageAccountKey "12345678"

您的腳本沒有任何參數。 你在你的腳本函數 ，它的參數。 任何功能之外，腳本頂部的param塊都會使腳本帶有參數。

例如：

param($A)

function Foo {
param($B)
  Write-Output $B
}

Foo -B $A
