Question

我可以看到nlog起作用是因为我的日志文件越来越大，但是只记录了一些东西，例如应用程序正在启动，路线正在更改等。

但是，无论我在何处放置logger.LogCritical或其他自定义日志方法，都无法正常工作。

我正在使用ASP.NET COre 3.1和最新的NLog。

这是我的启动代码：

 public static IHostBuilder CreateHostBuilder( string[] args ) =>
     Host.CreateDefaultBuilder( args )
       .ConfigureWebHostDefaults( webBuilder =>
       {
           webBuilder.UseStartup<Startup>();
       } )
       .ConfigureLogging( logging =>
       {
           logging.ClearProviders();
           logging.SetMinimumLevel( Microsoft.Extensions.Logging.LogLevel.Trace );
           logging.AddNLog( "nlog.config" );
       } );

和nlog.config：

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      autoReload="true"
      internalLogLevel="Info"
      internalLogFile="c:\temp\internal-nlog.txt">

  <!-- enable asp.net core layout renderers -->
  <extensions>
    <add assembly="NLog.Web.AspNetCore"/>
  </extensions>

  <!-- the targets to write to -->
  <targets>
    <!-- write logs to file  -->
    <target xsi:type="File" name="allfile" fileName="c:\temp\nlog-all-${shortdate}.log"
            layout="${longdate}|${event-properties:item=EventId_Id}|${uppercase:${level}}|${logger}|${message} ${exception:format=tostring}" />

    <!-- another file log, only own logs. Uses some ASP.NET core renderers -->
    <target xsi:type="File" name="ownFile-web" fileName="c:\temp\nlog-own-${shortdate}.log"
            layout="${longdate}|${event-properties:item=EventId_Id}|${uppercase:${level}}|${logger}|${message} ${exception:format=tostring}|url: ${aspnet-request-url}|action: ${aspnet-mvc-action}" />
  </targets>

  <!-- rules to map from logger name to target -->
  <rules>
    <!--All logs, including from Microsoft-->
    <logger name="*" minlevel="Trace" writeTo="allfile" />

    <!--Skip non-critical Microsoft logs and so log only own logs-->
    <logger name="Microsoft.*" maxlevel="Info" final="true" /> <!-- BlackHole without writeTo -->
    <logger name="*" minlevel="Trace" writeTo="ownFile-web" />
  </rules>
</nlog>

我在控制器中这样使用它：

           logger.LogInformation( "test critical IN CONTROLLER" );

这是将其注入构造器的方式：

  public AuthController( IMediator mediator, ILogger<AuthController> logger )
        {
            this.mediator = mediator;
            this.logger = logger;
        }

我可以看到他：

，但是没有日志。甚至不在log-all.txt文件中，该文件将记录所有内容，而与跟踪级别无关

这是我的appsettings.json

  "Logging": {
      "IncludeScopes": false,
      "LogLevel": {
        "Default": "Trace",
        "Microsoft": "Warning",
        "Microsoft.Hosting.Lifetime": "Information"
      }
    },

Nlog不记录自定义日志
