有人可以告诉我为什么 Azure Pipelines 不喜欢这个 yaml 文件吗？

谁能告诉我为什么在将此 YAML 文件放入管道时出现以下错误？

Line 14, Col 7: Unexpected Value Display Name
Line 45, Col 6: A sequence was not expected

Answer 1

请先查看此文档：YAML schema reference 和 Define variables，以下是设置多作业输出变量的示例 yaml。

jobs:
# Set an output variable from job A
- job: A
  pool:
    vmImage: 'vs2017-win2016'
  steps:
  - powershell: echo "##vso[task.setvariable variable=myOutputVar;isOutput=true]this is the value"
    name: setvarStep
  - script: echo $(setvarStep.myOutputVar)
    name: echovar

# Map the variable into job B
- job: B
  dependsOn: A
  pool:
    vmImage: 'ubuntu-18.04'
  variables:
    myVarFromJobA: $[ dependencies.A.outputs['setvarStep.myOutputVar'] ]  # map in the variable
                                                                          # remember, expressions require single quotes
  steps:
  - script: echo $(myVarFromJobA)
    name: echovar

因此以下 yaml 的 sn-p 应该是正确的语法供您参考。

pool:
  vmImage: windows-latest

variables: 
  azureSubscription: 'subscription here'
  RG: 'WClassroomInTheCloud'

jobs:
- job: job1   
  steps:
  - task: AzureCLI@1
    displayName: 'Azure CLI '
    inputs:
      azureSubscription: $(azureSubscription)
      scriptLocation: inlineScript
      inlineScript: |
        mkdir $(Pipeline.Workspace)\BlobFile
        az storage blob download --container-name $(containername) --file '$(Pipeline.Workspace)/s/student.json' --name 'student.json' --connection-string 'VALUE IN HERE'

  - pwsh: |
      cd '/home/vsts/work/1/s/'
      ls
      $armOutput = Get-Content '/home/vsts/work/1/s/student.json' | convertfrom-json
      $student = $armOutput.studentvalue #use student not studentvalue
      $type = $armOutput.type
      Write-Host "The value of [$student] is [$type]"
      Write-Host "##vso[task.setvariable variable=studentvalue;isOutput=true]$student" #use studentvalue not $studentvalue
    name: setvarStep

  - script: echo $(setvarStep.studentvalue)
    name: echovar

- job: job2
  displayName: Create Web App 
  dependsOn: job1
  variables:
    webappname: $[ dependencies.job1.outputs['setvarStep.studentvalue'] ]

  steps: 
  
  - task: AzureWebApp@1
    inputs:
      azureSubscription: $(azureSubscription)
      appType: 'webApp'
      resourceGroupName: $(RG)
      appName: $(webappname)
      package: $(System.DefaultWorkingDirectory)**/*.csproj

  - task: AzureAppServiceSettings@1

      appName: $(webappname)
      resourceGroupName: $(RG)
      # To deploy the settings on a slot, provide slot name as below. By default, the settings would be applied to the actual Web App (Production slot)
      # slotName: staging
      appSettings: |
        {
          "name": "DIAGNOSTICS_AZUREBLOBCONTAINERSASURL",
          "value": "VALUEINHERE",
          "slotSetting": false
        },
        {
          "name": "DIAGNOSTICS_AZUREBLOBRETENTIONINDAYS",
          "value": "365",
          "slotSetting": false
        },
        {
          "name": "OEM",
          "value": "netsupport",
          "slotSetting": false
        },
        {
          "name": "SCM_REPOSITORY_PATH",
          "value": "d:\\home\\respository",
          "slotSetting": false
        },
        {
          "name": "VIDEO_CLIENT_URL",
          "value": "https://signal-uks.classroom.cloud",
          "slotSetting": false
        },
        {
          "name": "WEBSITE_NODE_DEFAULT_VERSION",
          "value": "10.15.2",
          "slotSetting": false
        }

Answer 2

第二个错误是因为第 40 行的 steps 处于 webappname 的级别，而它本应处于 variables 的级别。通常不应使用单空格缩进来避免此类错误。

我不确定第一个错误，但请尝试在第 10 行写 displayName 而不是 dislayName。
