实现自定义的异常处理类
---------------------------------------------------------------------
public class MyExceptionFilter : IExceptionFilter
{
public bool AllowMultiple => true;
public async Task ExecuteExceptionFilterAsync(HttpActionExecutedContext actionExecutedContext, CancellationToken cancellationToken)
{
// throw new NotImplementedException();
Exception ex= actionExecutedContext.Exception;
//Console.WriteLine(ex.ToString());
}
}
注册自定义异常处理类
----------------------------------------------------------------------------
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional });
//config.Filters.Add(new MyFilter());
config.Filters.Add(new MyExceptionFilter());
}
}
