Azure DevOps如何获取任务中的安全变量值

Question

我在管道变量页面上将连接字符串声明为安全，但在管道中我无法获取该值。我已经阅读了文档中的相关页面，但当我想在任务中使用值时，它没有提供示例。 https://learn.microsoft.com/en-us/azure/devops/pipelines/process/variables?view=azure-devops&tabs=yaml%2Cbatch#secret-variables

The task where I want to get the value you can see below
- task: AzureWebAppContainer@1
        displayName: Deploy to App Service
        inputs:
          azureSubscription: 'free_subscription(id)'
          appName: 'app-service'
          containers: 'containerregistry.azurecr.io/something:$(tag)'
          **WANT TO USE IT HERE**
          appSettings: 'CONNECTION_STRING=$(CONNECTION_STRING)'

$(CONNECTION_STRING) 返回空字符串

编辑

更新了代码，但它无论如何都不起作用...应用设置中的连接字符串仍然为空。

- stage: Deploy
    displayName: Deploy to App Service
    jobs:
    - job: Deploy
      displayName: Deploy
      pool:
        vmImage: ubuntu-latest
      steps:
      - bash: echo "##vso[task.setvariable variable=CONNECTION_STRING]$CONNECTION_STRING"
        displayName: 'Set variable'
      - task: AzureWebAppContainer@1
        displayName: Deploy to App Service
        inputs:
          azureSubscription: 'free_subscription(id)'
          appName: 'app-service'
          containers: 'appnamecontainerregistry.azurecr.io/repository:$(tag)'
          appSettings: |
            [
              {
                "name": "CONNECTION_STRING",
                "value": "$(CONNECTION_STRING)",
                "slotSetting": false
              }
            ]

在选择 secret 管道变量时，您忽略了这一点:

这是referenced here因此，根据您的操作系统是 Linux 还是 Windows，它会是:Linux:$CONNECTION_STRINGWindows:%CONNECTION_STRING%
