Serilog 自定义接收器 - 使用 appsettings.json 设置最低级别不起作用

Question

我正在尝试编写一个自定义的 Serilog 接收器，但我似乎无法让“restrictedToMinimumLevel”参数工作。 我相信我的 appsettings.json 是正确的，因为接收器的发射方法确实运行； 但是，该方法适用于所有日志级别。 我错过了什么？

appsettings.json

{
    "Serilog":
    {
        "Using":
        [
            "Serilog.Sinks.Console",
            "CustomSerilogTest"
        ],
        "MinimumLevel":
        {
            "Default": "Debug"
        },
        "WriteTo":
        [
            {
                "Name": "Console",
                "Args":
                {
                    "theme": "Serilog.Sinks.SystemConsole.Themes.AnsiConsoleTheme::Code, Serilog.Sinks.Console",
                    "outputTemplate": "{Timestamp:yyyy-MM-dd HH:mm:ss} [{Level:u3}] {Message} {NewLine}{Exception}"
                }
            },
            {
                "Name": "MyCustomSink",
                "Args":
                {
                    "restrictedToMinimumLevel": "Error"
                }
            }
        ]
    }
}

定制水槽 Class

namespace CustomSerilogTest
{
    public class MyCustomSink : ILogEventSink
    {
        private readonly IFormatProvider _formatProvider;

        public MyCustomSink(IFormatProvider formatProvider)
        {
            _formatProvider = formatProvider;
        }

        public void Emit(LogEvent logEvent)
        {
            //method fires, but is not limited to errors
            var message = logEvent.RenderMessage(_formatProvider);
        }
    }

    public static class SerilogExtensions
    {
        public static LoggerConfiguration MyCustomSink(
          this LoggerSinkConfiguration loggerConfiguration,
          IFormatProvider formatProvider = null)
        {
            return loggerConfiguration.Sink(new MyCustomSink(formatProvider));
        }
    }
}

我想到了。 看来您必须在扩展方法中添加一个参数，如下所示：

public static class SerilogExtensions
{
    public static LoggerConfiguration MyCustomSink(
      this LoggerSinkConfiguration loggerConfiguration,
      LogEventLevel restrictedToMinimumLevel = LevelAlias.Minimum,
      IFormatProvider formatProvider = null)
    {
        return loggerConfiguration.Sink(new MyCustomSink(formatProvider), restrictedToMinimumLevel: restrictedToMinimumLevel);
    }
}
