public class MyAutorFilter : IAuthorizationFilter

config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",

);
// config.Filters.Add(new MyAutorFilter());
还有ActionFilter ExceptionFilter
apiResult 用法
public class ApiResult<T>
{
public int Code { get; set; }
public string Message { get; set; }
public T ReturnValue { get; set; }
}
public ApiResult<string> Get(int id)
{
if (id<0)
{
return new ApiResult<string> { Code = 1, Message = "年龄太小" };
}
else if(id>100)
{
return new ApiResult<string> { Code = 2, Message = "年龄太da" };
}
else
{
return new ApiResult<string> { Code = 0, ReturnValue="Hellp" };
}
}
