从私有nuget提要还原nuget包-Docker出现错误

我正在尝试构建docker映像，但在尝试从私有Nuget提要还原Nuget包时出现此错误。我尝试了来自internet的许多解决方案。到目前为止，没有任何效果。请帮助

我的Docker文件如下所示：-

FROM mcr.microsoft.com/dotnet/core/aspnet:2.2-stretch-slim AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/core/sdk:2.2-stretch AS build
WORKDIR /src
COPY ["Api/Api.csproj", "Api/"]
COPY ["Persistence.EntityFramework/Nuget.config", "Persistence.EntityFramework/"]
COPY ["Contracts/Contracts.csproj", "Contracts/"]
COPY ["Persistence/Persistence.csproj", "Persistence/"]
COPY ["Domain/Domain.csproj", "Domain/"]
COPY ["Handlers/Handlers.csproj", "Handlers/"]
COPY ["Localisation/Localisation.csproj", "Localisation/"]
COPY ["Persistence.EntityFramework/Persistence.EntityFramework.csproj", "Persistence.EntityFramework/"]
RUN dotnet restore "Persistence.EntityFramework/Persistence.EntityFramework.csproj" --configfile "Persistence.EntityFramework/Nuget.config"
RUN dotnet restore "Api/Api.csproj"
COPY . .
WORKDIR "/src/Api"
RUN dotnet build "Api.csproj" -c Release -o /app

FROM build AS publish
RUN dotnet publish "Api.csproj" -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "Security.Api.dll"]

我的Nuget.Config如下所示：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <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>
  <packageSources>
    <add key="NuGet.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="companyname" value="http://vnuget.companyname.com/privateNugetFeed/nuget/Packages"/>    
  </packageSources>
</configuration>

嗨，我找到问题了

我的Nuget配置文件中的包源链接不正确

应该是：-

 <add key="companyname" value="http://vnuget.companyname.com/privateNugetFeed/nuget"/>  

这已经解决了问题，docker现在正在正确构建！瞧

 <add key="companyname" value="http://vnuget.companyname.com/privateNugetFeed/nuget"/>
