Replace IExceptionHandler in Web Api 2.2 with OWIN middleware exception handler

阅读更多关于 Replace IExceptionHandler in Web Api 2.2 with OWIN middleware exception handler

问题 I have created an OWIN middleware to catch exceptions. The middleware does nothing really but wrap the next call with try catch like this try { await _next(environment) } catch(Exception exception){ // handle exception } The problem is that the middlware is not capturing the exception because the exception is been handled by the default implementation of IExceptionHandler which returns an xml with the stack trace. I understand that I can replace the default IExceptionHandler implementation

问题 I'm trying to implement both Attribute Routing and the VersionedRoute from RoutingConstaints Sample but when I use both on a controller, the versioned attribute no longer works.

404 Not Found or Bad Request?

阅读更多关于 404 Not Found or Bad Request?

问题 Let's say that we have the following REST call: GET api/companies/5 (get company with id 5) If company '5' doesn't exist, we would typically return a 404 Not Found response. But now, let's take this call: GET api/companies/5/invoices/10 (get invoice 10 from company 5) Now, if company '5' doesn't exist, do we still return a 404 Not Found ? Or should a 404 only be returned if the outer most resource can not be found (invoice 10, in this case). Would Bad Request perhaps be a better option? 回答1:

问题 I've created a RESTful web service using ASP.NET WebApi v2 and I'm using Swashbuckle to generate swagger UI for API documentation. All API calls are under http://localhost/api/ and the swagger UI page is at http://localhost/browser/index (the 'browser' part is configurable). Browsing to http://localhost/ however will land on a empty page, so my question is is it possible to route http://localhost/ to http://localhost/browser/index so the user will be able to see the API documentation just by
