ASP.NET Core UseExceptionHandler extension do not work with ABP #1821

bozkan created 5 years ago

ABP Framework version: v4.3.0
UI type: Angular
DB provider: EF Core
Tiered (MVC) or Identity Server Separated (Angular): yes
Exception message and stack trace:
Steps to reproduce the issue:" Apply method explained on https://docs.microsoft.com/en-us/aspnet/core/fundamentals/error-handling?view=aspnetcore-5.0#exception-handler-lambda

I am trying to globally catch (and modify) any exceptions occured on my ABP project and trying different methods which no one could be successful so far. One of them is using the exception handler lambda explained on https://docs.microsoft.com/en-us/aspnet/core/fundamentals/error-handling?view=aspnetcore-5.0#exception-handler-lambda. Even if I configured the lambda and throw exception in some method, the lambda method is not hit.

Hi,

Can you share your code? thanks.

It's just a simple app service method that I throw exception on purpose.

Hi,

It works for me.

public class IndexModel : AbpPageModel
{
    public void OnGet()
    {
        throw new Exception("test");
    }
}

app.UseExceptionHandler(x => x.Run(async errorContext =>
{
    errorContext.Response.StatusCode = (int) HttpStatusCode.InternalServerError;
    errorContext.Response.ContentType = "text/html";

    await errorContext.Response.WriteAsync("<html lang=\"en\"><body>\r\n");
    await errorContext.Response.WriteAsync("ERROR!<br><br>\r\n");

    var exceptionHandlerPathFeature =
        errorContext.Features.Get<IExceptionHandlerPathFeature>();

    if (exceptionHandlerPathFeature?.Error is FileNotFoundException)
    {
        await errorContext.Response.WriteAsync(
            "File error thrown!<br><br>\r\n");
    }

    await errorContext.Response.WriteAsync(
        "<a href=\"/\">Home</a><br>\r\n");
    await errorContext.Response.WriteAsync("</body></html>\r\n");
    await errorContext.Response.WriteAsync(new string(' ', 512));
}));
