C# 无法加载源的服务索引

我在.net core 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。构建服务器似乎无法访问工件提要，尽管这适用于其他解决方案。以下是错误：

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]

这是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:

    ArtifactName: 'drop'
    publishLocation: 'Container'

有没有关于如何解决身份验证问题的建议

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。 以下是完整的错误消息：

请尝试在DevOps中注册，并通过以下命令使用个人访问令牌注册package feed：

---

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

Hi@CeceDong感谢您的建议。我用命令更新了构建服务器上的源代码，但构建仍然失败，出现了相同的身份验证错误。请参阅问题中更新的错误详细信息。还有其他建议吗？请尝试将system.debug设置为true，以查看是否有更多消息。另外，尝试在提要中授予生成代理帐户

Contributor

权限。我向生成代理授予了Contributor权限并设置了调试标志，但没有看到任何与问题相关的内容。我想知道这是否与.NETCore有关。发现此问题，但不确定是否是同一问题。还有其他建议吗？您是否在生成代理计算机上检查了

%appdata%\NuGet\NuGet.config

？有``信息吗？NuGet Authenticate任务是最新推荐的对来自管道的工件提要进行身份验证的方法，但它在Devops 2019中不存在。请检查以下链接中的解决方法，以查看它是否有助于您：
