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);
        }
    }
