azure - 在 nuget.config 中提供 globalPackagesFolder 时，为 dot net core 服务构建管道失败，并出现错误 401(未经授权)

Question

在 ADO 中为 dot net core 服务构建管道时遇到一个奇怪的问题。

我正在尝试为 nuget.config 文件中引用的包设置路径。下面是 nuget.config 文件。

    <?xml version="1.0" encoding="utf-8"?>
<configuration>
  <config>
    <add key="repositorypath" value="..\..\Packages" />
     <!--Affects projects using PackageReference only--> 
    <add key="globalPackagesFolder" value="..\..\Packages" />
    <add key="dependencyversion" value="HighestMinor" />
  </config>
  <solution>
    <add key="disableSourceControlIntegration" value="true" />
  </solution>
  <packageRestore>
    <!-- Allow NuGet to download missing packages -->
    <add key="enabled" value="True" />
    <!-- Automatically check for missing packages during build in Visual Studio -->
    <add key="automatic" value="True" />
  </packageRestore>
  <activePackageSource>
    <add key="All" value="(Aggregate source)" />
  </activePackageSource>
  <packageSources>
    <add key="NuGet Server" value="my private feed" />
    <add key="NuGet" value="https://api.nuget.org/v3/index.json" />
  </packageSources>
  <disabledPackageSources />
</configuration>

添加以下行后，出现 401 Unauthorized。

<add key="globalPackagesFolder" value="..\..\Packages" />

异常

Retrying 'FindPackagesByIdAsync' for source 'myfeed/nuget/v3/flat2/microsoft.extensions.dependencyinjection/index.json'.
  Response status code does not indicate success: 401 (Unauthorized).
  Restore failed in 8.09 sec for /home/vsts/work/1/s/Service/Test/myproject.Tests/myproject.Tests.csproj.

以下是构建管道中的任务

pool:
  vmImage: 'ubuntu-latest'

variables:
  buildConfiguration: 'Release'

steps:

- task: NuGetToolInstaller@1

- task: NuGetCommand@2
  inputs:
    #command: 'restore'
    restoreSolution: 'Service/myservice.sln'
    feedsToUse: config
    nugetConfigPath: 'Service/.nuget/nuget.config'
    externalFeedCredentials: 'MyPackages'

- script: dotnet build "Service/myservice.sln" --configuration $(buildConfiguration) -p:langversion=latest
  displayName: 'dotnet build $(buildConfiguration)'

Answer 1

Build Pipeline for dot net core service fails with error 401 (Unauthorized) when provided globalPackagesFolder in nuget.config

根据错误信息:

Retrying 'FindPackagesByIdAsync' for source 'myfeed/nuget/v3/xxx'.
  Response status code does not indicate success: 401 (Unauthorized).

我们可以知道它正在尝试访问您的私有(private) nuget feed 并收到此 401(未经授权)错误。您似乎没有在 nuget.config 文件中提供认证信息。

要解决此问题，请尝试在 nuget.config 中添加认证信息，如下所示:

  <packageSourceCredentials>
    <NuGet Server>
      <add key="Username" value="xxxxx" />
      <add key="ClearTextPassword" value="Password/PAT" />
    </NuGet Server>
  </packageSourceCredentials>

检查this线程了解更多详细信息。

希望这有帮助。
