Return View(model: statusCodePagesInfoFeature?.StatusMessage)
Public IActionResult StatusCode(int code) Public class CustomErrorResponseFeature : ICustomErrorResponseFeature Public interface ICustomErrorResponseFeature Custom context feature, to store information from the exception Public NotFoundResponseException(string message) Public class NotFoundResponseException : CustomErrorResponseException Public CustomErrorResponseException(string message, int statusCode) Public class CustomErrorResponseException : Exception Custom exceptions that can be thrown within the middleware For that, we create a CustomErrorResponseMiddleware which basically checks for CustomErrorResponseException exceptions and then re-executes the middleware pipeline for our error handler. There is not really a way to add additional details to it.īut what we could do is create our own error handling implementation on top of that re-execution model. But as Chris Pratt already mentioned, those status codes are typically limited to just their code.

That way, you are able to fully design status code errors. So when you return a non-successful status code from MVC, the middleware detects that and then re-executes the whole pipeline for a status code error route. That middleware allows a pipeline re-execution model, to allow handling status code errors through the normal MVC pipeline. What you could do is something similar to how the StatusCodePages middleware works. I am assuming there is a way to do this with a attribute but I have yet to find a way to do either of these tasks. I also need the ability in a controller to return the standard text or JSON response during the error for cases when I expect a JSON response (API actions and such). How can I have custom error code pages that display the proper error. I could have sworn I used to do this in the past with classic. Calling NotFound() without any parameters hits the error controller but as soon as I pass a message through, the controller is never used and a simple text message is displayed. I expected this message to be pushed to the controller however this is not the case. I setup custom error code pages support in the Startup.cs class file and then created a simple view in a controller that does public IActionResult Example1 => NotFound("Some custom error message"). For more details, see this page in the Information Center, Overview of the custom error page policy.I am trying to create a custom error code page that displays a message I pass to it in my. If the error originates from the WebSphere Application Server Web container, as a result of a WebSphere Application Server problem or perhaps the Web application is not active, then it might be necessary to use the WebSphere Application Server proxy server in conjunction with a special error page application.
WebSphere Application Server proxy server For more details, see the Information Center topic Web.xml.įor example, the following tells the Web application to send error404.html page if there is a 404 error in the application. If the request is handled by a Web application running in WebSphere Application Server, and an error occurs, use the error-page option in web.xml (or web_merged.xml if it exists) to specify a customized error page. Web application running in WebSphere Application Server If the request is handled by IBM HTTP Server, and an error occurs, use the ErrorDocument directive in the IBM HTTP Server config ( nf) to specify a customized error page for that specific error, as described here, ErrorDocument Directive.įor example, the following tells IBM HTTP Server to send the custom404.html page if there is a 404 error in IBM HTTP Server: The Web server plug-in determines if the request should be handled by WebSphere Application Server, or should be handled by IBM HTTP Server.
SCREENSTEPS CUSTOM ERROR PAGE HOW TO
The purpose of this technote is to act as a single point of reference with links to other documentation regarding how to create customized error pages in various IBM software products. However, it is possible to create customized error pages and configure the IBM software to send the customized error pages instead. By default, the error page returned to the browser is generic in appearance. When a request comes in from a Web browser, there might be an error at any of those layers of software. In a typical IBM WebSphere Application Server environment, there are many pieces of IBM software involved, such as IBM HTTP Server, Web server plug-in, and WebSphere Application Server.
