取得驗證應用程式以從程式碼存取 Azure SQL 資料庫所需的值

適用於：Azure SQL 資料庫

若要從程式碼建立和管理 Azure SQL 資料庫，必須使用 Microsoft Entra ID (先前的 Azure Active Directory) 註冊應用程式。 必須在與您的 Azure SQL 資料庫資源相同的 Microsoft Entra 租用戶中註冊該應用程式。

建立服務主體以從應用程式存取資源

下列範例會建立 Active Directory (AD) 應用程式和我們驗證 C# 應用程式所需的服務主體。 指令碼會輸出上述 C# 範例所需的值。 如需詳細資訊，請參閱使用 Azure PowerShell 建立服務主體以存取資源。

PowerShell

重要

SQL Database 仍然支援 PowerShell Azure Resource Manager (RM) 模組，但所有未來的開發都是針對 Az.Sql 模組。 AzureRM 模組在至少 2020 年 12 月之前都還會持續收到 Bug 修正。 Az 模組和 AzureRm 模組中命令的引數本質上完全相同。 如需其相容性的詳細資訊，請參閱新的 Azure PowerShell Az 模組簡介。

# sign in to Azure

# for multiple subscriptions, uncomment and set to the subscription you want to work with
#$subscriptionId = "{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}"
#Set-AzContext -SubscriptionId $subscriptionId

$appName = "{app-name}" # display name for your app, must be unique in your directory
$uri = "http://{app-name}" # does not need to be a real uri

# create an AAD app
$azureAdApplication = New-AzADApplication -DisplayName $appName -HomePage $Uri -IdentifierUris $Uri -Password $secret

# create a Service Principal for the app
$svcprincipal = New-AzADServicePrincipal -ApplicationId $azureAdApplication.ApplicationId

Start-Sleep -s 15 # to avoid a PrincipalNotFound error, pause here for 15 seconds

# if you still get a PrincipalNotFound error, then rerun the following until successful.
$roleassignment = New-AzRoleAssignment -RoleDefinitionName Contributor -ServicePrincipalName $azureAdApplication.ApplicationId.Guid

# output the values we need for our C# application to successfully authenticate
Write-Output "Copy these values into the C# sample app"

Write-Output "_subscriptionId:" (Get-AzContext).Subscription.SubscriptionId
Write-Output "_tenantId:" (Get-AzContext).Tenant.TenantId

Start-Sleep -s 15 # to avoid a PrincipalNotFound error, pause for 15 seconds

# if you still get a PrincipalNotFound error, then rerun the following until successful.

# output the values we need for our C# application to successfully authenticate
Write-Output "Copy these values into the C# sample app"

Write-Output "-subscriptionId:" (az account show --query "id")
Write-Output "_tenantId:" (az account show --query "tenantId")
Write-Output "_applicationId:" $azureAdApplication.ApplicationId.Guid
Write-Output "_applicationSecret:" $secret
