背景介绍:基于netcore2.2开发api接口程序,自定义了一个异常捕获中间件,用于捕获未经处理的异常以及状态码404、500等访问(设计的出发点就是,出现了非200的响应,我这边全部会进行处理成200,并返回固定格式的JSON格式数据),并进行统一的信息返回。

返回的JSON实体定义如下:

 

 

中间件部分代码如下所示:

 

 

 

 

异常截图如下:

 

 

 文字信息:fail: Microsoft.AspNetCore.Server.Kestrel[13]
      Connection id "0HLVT9ADLSD7M", Request id "0HLVT9ADLSD7M:00000001": An unhandled exception was thrown by the application.
