azure - .Net6 Azure Functions 中的 ILogger 依赖项注入(inject)问题

Question

我最近将 .NET 3.1 azure 函数代码转换为 .NET6。启动类中的以下代码工作正常，在作为 Azure 函数部署到 Azure 时，但在转换为 .NET6 后，我们收到以下错误。

Microsoft.Azure.WebJobs.Script.WebHost: Invalid host services detected. Microsoft.Azure.WebJobs.Script.WebHost: The following service registrations did not match the expected services: [Missing] ServiceType: Microsoft.Extensions.Logging.ILoggerProvider, Lifetime: Singleton, ImplementationType: Microsoft.Azure.WebJobs.Script.Diagnostics.FunctionFileLoggerProvider, Microsoft.Azure.WebJobs.Script, Version=4.11.0.0, Culture=neutral, PublicKeyToken=null [Missing] ServiceType: Microsoft.Extensions.Logging.ILoggerProvider, Lifetime: Singleton, ImplementationType: Microsoft.Azure.WebJobs.Script.Diagnostics.HostFileLoggerProvider, Microsoft.Azure.WebJobs.Script, Version=4.11.0.0, Culture=neutral, PublicKeyToken=null.

启动类代码

public class Startup : IWebJobsStartup
{
    public void Configure(IWebJobsBuilder builder)
    {
        builder.Services.AddCashMatchingService();
        builder.Services.AddDataManagerService();
           
        builder.Services.AddOptions();
        builder.Services.AddSingleton<ILoggerFactory, LoggerFactory>();
        builder.Services.AddSingleton(typeof(ILogger<>), typeof(Logger<>));
        builder.Services.AddSingleton<ILoggerProvider>(p=>new DebugLoggerProvider());
        builder.Services.AddLogging(lb => lb.ClearProviders()
            .AddSerilog(
                Activator.CreateInstance<LoggerConfiguration>().Enrich
                    .FromLogContext()
            .WriteTo.AzureBlobStorage(Environment.GetEnvironmentVariable(
                 "azureStorageConnection-StorageConnection"),
                  (Serilog.Events.LogEventLevel)Enum.Parse(
                     typeof(Serilog.Events.LogEventLevel),
              Environment.GetEnvironmentVariable("Serilog_MinimumLevel")),
              Environment.GetEnvironmentVariable("Serilog_ContainerName"),
              Environment.GetEnvironmentVariable("Serilog_StorageFileName"))
            .WriteTo.ApplicationInsights(TelemetryConfiguration.CreateDefault(),
                TelemetryConverter.Events)
            .CreateLogger()));
    }
}

不要清除 comment by Loul G 中提到的日志记录提供程序.

我也遇到了同样的问题。看起来 AZ Functions 由于某些未知原因需要这 2 个特定的记录器提供程序
