c# - Azure function 2.x ILogger 与.net core ILogger 不兼容？

Question

我一直在尝试将 .net core 库项目引用到我的 Azure 函数项目中，以调用 .net core 类库中定义的进程之一。

.net core 库项目使用 ILogger。

但是，每当我尝试运行函数时，都会收到以下错误:

[29/11/2019 1:08:35 AM] The 'Function1' function is in error: Microsoft.Azure.WebJobs.Host: Error indexing method 'Function1'. Microsoft.Azure.WebJobs.Host: Cannot bind parameter 'log' to type ILogger`1. Make sure the parameter Type is supported by the binding. If you're using binding extensions (e.g. Azure Storage, ServiceBus, Timers, etc.) make sure you've called the registration method for the extension(s) in your startup code (e.g. builder.AddAzureStorage(), builder.AddServiceBus(),

这是我的代码:

[FunctionName("Function1")]
        public static void Run([TimerTrigger("0 */5 * * * *")] TimerInfo myTimer, ILogger log)
        {
            log.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
            // string templateFile = Path.Combine(context.FunctionAppDirectory, "Data", "HelloHttpOutputTemplate.txt");
            Startup.Main(null).Wait();
        }

我还确认我的 .net core 项目和函数项目引用了相同版本的 ILogger:

'microsoft.extensions.logging.abstractions\3.0.0\lib\netstandard2.0'

如果我从函数项目中删除 .net core 库项目引用，那么它就可以工作。

我的函数CS项目文件:

更新:

现已使用.net core 3.0。

但仍然遇到同样的错误:

这是我的 .csproj 文件:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp3.0</TargetFramework>
    <AzureFunctionsVersion>v2</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="librdkafka.redist" Version="1.2.1" />
    <PackageReference Include="Microsoft.Extensions.Configuration" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.Configuration.EnvironmentVariables" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.Configuration.FileExtensions" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.Configuration.Json" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.DependencyInjection" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.DependencyInjection.Abstractions" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.Http" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.Logging.Console" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.Options" Version="3.0.0" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="1.0.28" />
  </ItemGroup>
  <ItemGroup>
    <None Update="host.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="local.settings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
  </ItemGroup>
</Project>

解决方案:

降级 Microsoft.Extensions.Http、Microsoft.Extensions.Logging.Console、Microsoft.Extensions.Logging.Debug 和Microsoft.Extensions.Options 从 3.0.0 到 2.2.0。然后错误就解决了。

原始答案:

我重现了您的错误:

原因:

程序集冲突。关键是您的最后四个程序集引用。

解决方案:

将它们更改为2.2.0。我这边一切顺利。请尝试一下，如果有困难请告诉我。
