无法加载源的服务索引

Question

我在 .net 核心 3.1 解决方案的内部部署 Devops 2019 构建服务器上遇到未经授权的错误。 尽管这适用于其他解决方案，但构建服务器似乎无法访问工件提要。 这是错误：

Active code page: 65001
[command]"C:\Program Files\dotnet\dotnet.exe" test C:\a\_work\61\s\MySolution\MySolution.csproj --logger trx --results-directory C:\a\_work\_temp
C:\Program Files\dotnet\sdk\3.1.302\NuGet.targets(128,5): error : Unable to load the service index for source https://mydomin/tfs/DefaultCollection/_packaging/MyFeed/nuget/v3/index.json. [C:\a\_work\61\MySolution\MySolution.csproj]
C:\Program Files\dotnet\sdk\3.1.302\NuGet.targets(128,5): error :   Response status code does not indicate success: 401 (Unauthorized). [C:\a\_work\61\s\MySolution\MySolution.csproj]

这里是 pipeline.yaml 文件，错误发生在 DotNetCoreCLI@2 步骤：

# ASP.NET Core (.NET Framework)
# Build and test ASP.NET Core projects targeting the full .NET Framework.
# Add steps that publish symbols, save build artifacts, and more:
# https://docs.microsoft.com/azure/devops/pipelines/languages/dotnet-core

trigger:
- master

pool: 'Default'

variables:
  solution: '**/*.sln'
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Release'

steps:
- task: NuGetToolInstaller@1
  inputs:
    versionSpec: '5.x'

- task: NuGetCommand@2
  inputs:
    restoreSolution: '$(solution)'

- task: VSBuild@1
  inputs:
    solution: '$(solution)'
    msbuildArgs: '/p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:DesktopBuildPackageLocation="$(build.artifactStagingDirectory)\WebApp.zip" /p:DeployIisAppPath="Default Web Site"'
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'

- task: DotNetCoreCLI@2
  inputs:
    command: 'publish'
    publishWebProjects: true
    arguments: '--configuration $(buildConfiguration) --self-contained true  -f netcoreapp3.1 -r win10-x64 --output $(Build.ArtifactStagingDirectory)' 

- task: PublishBuildArtifacts@1
  inputs:
    PathtoPublish: '$(Build.ArtifactStagingDirectory)'
    ArtifactName: 'drop'
    publishLocation: 'Container'

任何建议如何解决身份验证问题？

我尝试在构建服务器上更新工件提要的 PAT 令牌，但没有成功。 这是完整的错误消息：

请尝试在 DevOps 中创建 PAT ，并通过以下命令使用个人访问令牌注册 package 提要：

nuget sources add -name {your feed name} -source {your feed URL} -username {anything} -password {your PAT}
