问题描述

在带有 system.debug=true 的 Azure DevOps Release Pipeline 中运行 Azure Powershell 任务时，您将获得类似于以下内容的输出：

我需要将 Azure DevOps 连接的 SPN 添加到资源。更改订阅或管道时，SPN 也会更改，我不想硬编码该值。由于该值打印在 system.debug=true 输出中，我想知道如何在管道任务中访问我自己的 SPN。spnObjectId":"76055cb6-3b75-4191-9309-306b32dad443"是否可以使用 Powershell 以某种方式读出？

解决方案

可以使用 Get-AzureRmContext 访问有关服务主体的信息，但信息有限，并且某些信息在日志中被混淆，因此您需要再次调用 Get-AzureRmServicePrincipal 以访问 ObjectId

$Context = Get-AzureRmContext
$AzureDevOpsServicePrincipal = Get-AzureRmADServicePrincipal -ApplicationId $Context.Account.Id
$ObjectId = $AzureDevOpsServicePrincipal.Id

暴露的 Id$Context.Account.Id是服务主体 ApplicationId
