azure - Azure DevOps Pipeline 上的 YAML 解析器错误

Question

我在我的 azure Devop 管道上遇到以下错误，它似乎与参数循环有关，但尽管以多种不同的方式编写脚本，我似乎无法摆脱它。 YAML 验证器和我的 YAML linter 未检测到问题。

/azure-pipelines.yml(行:1，列:12):意外值“”

下面是我的代码，它也使用了一个模板，我将把它包含在它下面。

azure-pipelines.yml

parameters:
steps:
- ${{ each project in parameters.projects }}:
  - task: UsePythonVersion@0
    displayName: 'Setting python version to 3.7'
    inputs:
      versionSpec: '3.7'
      architecture: 'x64'

  - script: |
      pushd '$(System.DefaultWorkingDirectory)/${{ project }}'
      pip install -r requirements.txt
    displayName: 'Install prerequisites'

  - task: ArchiveFiles@2
    displayName: 'Archive files'
    inputs:
      rootFolderOrFile: '$(System.DefaultWorkingDirectory)/${{ project }}'
      includeRootFolder: false
      archiveFile: '$(System.DefaultWorkingDirectory)/${{ project }}.zip'

  - task: PublishBuildArtifacts@1
    inputs:
      PathtoPublish: '$(System.DefaultWorkingDirectory)/${{ project }}.zip'
      artifactName: 'drop'

  - task: AzureResourceManagerTemplateDeployment@3
    displayName: 'ARM Template deployment: Resource Group scope'
    
    inputs:
      azureResourceManagerConnection: $(serviceConnectionName)
      subscriptionId: $(subscriptionId)
      resourceGroupName: $(resourceGroupName)
      location: $(resourceGroupLocation)
      csmFile: 'deployment_template.json'
      overrideParameters: '-appName ${{ project }} -storageAcctName $(storageAcctName)  -hostingPlanName $(hostingPlanName)'

  - task: AzureFunctionApp@1
    inputs:
      azureSubscription: $(serviceConnectionName)
      appType: functionAppLinux
      appName: ${{ project }}
      package: '$(System.DefaultWorkingDirectory)/${{ project }}.zip'

如果我将你的 azure-pipelines.yml 放入 Azure DevOps 中的管道编辑器中，它会用警告标记 parameters: 的行结尾

"Incorrect type. Expected "array"."

到目前为止，我还没有在管道上使用模板，但是来自 MS doc page ，似乎您需要像这样指定要传递的参数:

#azure-pipelines.yml

parameters:
- name: projects
  type: object #object, since you are passing a list of strings
steps:
- ${{ each project in parameters.projects }}:
