Serilog - 如何制作自定义控制台输出格式? [英] Serilog - how to make custom console output format?

问题描述

我正在使用 Serilog 和 serilog-sinks-console 在我的 C# 项目中，我想知道如何在不创建全新格式化程序的情况下修改控制台输出的格式.我只需要调整一件事信息 java (slf4j/logback) 之类的格式.

I am using Serilog with serilog-sinks-console in my C# project and I am wondering how can I modify format of console output without creating whole new formatter. I just need to adjust one thing info java (slf4j/logback) like format.

从这里:

00:19:49 [DBG] Microsoft.AspNetCore.Hosting.Internal.WebHost - App starting
00:19:49 [DBG] Microsoft.AspNetCore.Hosting.Internal.WebHost - App started

进入这个:

00:19:49 [DBG] m.a.h.i.WebHost - App starting
00:19:49 [DBG] m.a.h.i.WebHost - App started

或者只是这种简单的格式:

or just this simple format:

00:19:49 [DBG] WebHost - App starting
00:19:49 [DBG] WebHost - App started

推荐答案

感谢@Ruben Bartelink 的指导.如果其他人会想知道如何做这样的事情，这里是一个简单的例子:

Thanks for the direction to @Ruben Bartelink. If anyone else will be wondering how to do such thing here is the simple example:

更丰富:

class SimpleClassEnricher : ILogEventEnricher
{
  public void Enrich(LogEvent logEvent, ILogEventPropertyFactory propertyFactory)
  {
    var typeName = logEvent.Properties.GetValueOrDefault("SourceContext").ToString();
    var pos = typeName.LastIndexOf('.');
    typeName = typeName.Substring(pos + 1, typeName.Length - pos - 2);
    logEvent.AddOrUpdateProperty(propertyFactory.CreateProperty("SourceContext", typeName));
  }
}

然后用法:

Log.Logger = new LoggerConfiguration()
    .MinimumLevel.Debug()
    .Enrich.With(new SimpleClassEnricher())
    .WriteTo.Console(outputTemplate: "{Timestamp:HH:mm:ss} [{Level:u3}] {SourceContext} - {Message:lj}{NewLine}{Exception}")
    .CreateLogger();
