方法1：继承IExceptionLogger

ExceptionLogger是框架提供的表示未处理的异常记录器的抽象类

public class RecordExceptionLogger : ExceptionLogger    {        public void LogCore(ExceptionLoggerContext context)        {            var request = context.Request;            LogUtil.WriteLog(request, context.Exception);        }        public override async Task LogAsync(ExceptionLoggerContext context, CancellationToken cancellationToken)        {            await Task.Run(() => LogCore(context), cancellationToken);        }    }
