        public readonly ISystemService _systemService;
        public readonly ILogger<IndexModel> _logger;

public IndexModel(ISystemService systemService, ILogger<IndexModel> logger)
        {
            _systemService = systemService;
            _logger = logger;
        }

public void OnGet()
        {
            _logger.LogInformation("正常日志记录");
            ViewData["Description"] = _systemService.GetDescription();
            //触发异常
            throw new Exception("测试异常状态日记记录");
        }
    }
```

```
public class ExceptionLogFilter : IAsyncExceptionFilter
    {
        public async Task OnExceptionAsync(ExceptionContext context)
        {
            Furion.Logging.Log.ScopeContext(ctx =>
            {
                //给日志上下文添加额外数据
                ctx.Set("TestContextData", "---来自ExceptionFilter的测试数据！---");
            });
            await Task.CompletedTask;
        }
    }
```

```
internal class DatabaseLoggingWriter : IDatabaseLoggingWriter
    {
        public void Write(LogMessage logMsg, bool flush)
        {
            Console.WriteLine("上下文额外数据是：{0}", logMsg.Context.Get("TestContextData"));
            return;
        }
    }
```
我想在ExceptionFilter中给日志上下文附加数据，然后在DatabaseLoggerWriter中写入数据库。但到了DatabaseLoggerWriter logMsg.Context为空值。
正常的日志通过PageFilter附加数据没有这个问题。

```
internal class RazorPageLogFilter : IAsyncPageFilter
    {
        public async Task OnPageHandlerExecutionAsync(PageHandlerExecutingContext context, PageHandlerExecutionDelegate next)
        {
            Furion.Logging.Log.ScopeContext(ctx =>
            {
                //给日志上下文添加额外数据
                ctx.Set("TestContextData", "来自PageFilter的测试数据！");
            });
            await next.Invoke();
        }

public Task OnPageHandlerSelectionAsync(PageHandlerSelectedContext context)
        {
            return Task.CompletedTask;
        }
    }

```
