问题
I wrote some WebAPI controllers using WebAPI for DotNetNuke 7.0 using this method
Everything worked great.
Today I upgraded DNN to 7.2.1 and upgraded my projects to ASP.NET Web API2 and my services on my local machine are now not working - they return "HTTP Error 404.0 - Not Found".
I think it is something to do with IIS and extensionless URLs - I checked IIS and DesktopModules is not an application as suggested here.
I tried Fiddler and F12 Debugging tools and the message is giving no clues away. How can I debug this to work out where the problem lies?
回答1:
- The folder that the webapi module is coming from supposed to be not an application, meaning it suppose to use the main web.config.
- Check the web.config (file diff), what's got changed between the upgrades.
