Web API offers some powerful routing behaviour. Let’s look at how we can use this in our app to avoid needing a new Controller for every Translation we wish to offer (again, ignore the fact our sample is likely only ever to require two way!).
We currently have a single AlphabetToMorseController with our old ITranslator implementation. In the previous tutorial we abstracted our service into an extensible dictionary, this should allow us to take our Translator Key as a routing parameter and our string to translate as a parameter in the URI on our API.
By the end of the post we’ll have refactored the existing AlphabetToMorseController to a generic TranslatorController, with our ITranslatorService being injected. The Key will be provided through a Web API Route, and the Get Requested to the Controller will return a collection of available Translators.
