.net core 自定义异常信息

思路：在startup.cs的configservice中配置一下，异常实现 ExceptionFilterAttribute 接口

 1 public class ExceptionConfig
 2 {
 3     public static void ConfigureServices(IServiceCollection services)
 4     {
 5         //自定义捕捉异常
 6         services.AddControllersWithViews(
 7             options => options.Filters.Add(typeof(CustomerExceptionFilterAttribute))
 8             );
 9 
10     }
11 
12     public static void Configure(IApplicationBuilder app, IWebHostEnvironment env)
13     {
14 
15        
16     }
17 }

 1  public class CustomerExceptionFilterAttribute : ExceptionFilterAttribute
 2  {
 3 
 4      public CustomerExceptionFilterAttribute() { }
 5 
 6 
 7      public override void OnException(ExceptionContext context)
 8      {
 9          // base.OnException(context);
10          if (!context.ExceptionHandled)
11          {
12 
13              context.Result = new JsonResult(new
14              {
15                  Result = false,
16                  Msg = "请联系开发",
17                  Debug = context.Exception.Message
18              });
19 
20              context.ExceptionHandled = true;
21          };
22      }
23 
24  }
