IExceptionHandler
.
Что-то вроде:
public class APIErrorHandler : IExceptionHandler
{
public Task HandleAsync(ExceptionHandlerContext context, CancellationToken cancellationToken)
{
var customObject = new CustomObject
{
Message = new { Message = context.Exception.Message },
Status = ... // whatever,
Data = ... // whatever
};
//Necessary to return Json
var jsonType = GlobalConfiguration.Configuration.Formatters.JsonFormatter;
json.SerializerSettings.Formatting = Newtonsoft.Json.Formatting.Indented;
var response = context.Request.CreateResponse(HttpStatusCode.InternalServerError, customObject, jsonType);
context.Result = new ResponseMessageResult(response);
return Task.FromResult(0);
}
}
и в разделе конфигурации WebAPI (public static void Register(HttpConfiguration config)
) напишите:
config.Services.Replace(typeof(IExceptionHandler), new APIErrorHandler());
