Developer exception page is useful only for development environment, we can not show it in production environment, also it's not helpful in case of Web-Api.
So, we can create a controller for global error handling,and we can configure it using ExceptionHandler middle-ware like:
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
//if (env.IsDevelopment())
//{
// app.UseDeveloperExceptionPage();
//}
app.UseExceptionHandler("/Error");
app.UseMvc();
}
we can create controller and action methods like below :
public class ErrorController : Controller
{
private readonly IConfiguration config;
public ErrorController(IConfiguration config)
{
this.config = config; // with the help of Iconfiguration we can access appSetting here.
}
[Route("/Error")]
public ActionResult Get([FromServices] IHostingEnvironment webHostEnvironment)
{
var feature = HttpContext.Features.Get<IExceptionHandlerPathFeature>();
var ex = feature?.Error;
var isDev = webHostEnvironment.IsDevelopment();
var problemDetails = new ProblemDetails
{
Status = (int)HttpStatusCode.InternalServerError,
Instance = feature?.Path,
Title = isDev ? $"{ex.GetType().Name}: {ex.Message}" : "An error occurred.",
Detail = isDev ? ex.StackTrace : null,
};
return StatusCode(problemDetails.Status.Value, problemDetails);
//:Other-way to return errors in json format
var feature = HttpContext.Features.Get<IExceptionHandlerPathFeature>();
return Json(new
{
StatusCode = 500,
ContentType = "Application/json",
SerializerSettings = "",
Value = feature.Error.Message
});
}
}
