Refit

Refit is the smartest client abstraction because it generates a client from an interface. All you have to do is provide an abstraction:

1. To use the Refit library, first install the Refit NuGet:

   dotnet add package Refit

2. To create a client in Refit, first create an interface with HTTP methods:

   public interface IStarWarsClient
   {
       [Get("/films")]
       public Task<ApiResult<IEnumerable<Film>>> GetFilms();
   }

Please note that the endpoint here is /films rather than films. If you run the code with films, you will get an exception suggesting that you change the endpoint with a preceding /.

3. To resolve the client, simply run the following code:

   var client = RestService.For<IStarWarsClient>("https://swapi.dev/api/");

On running the demo, the following output gets displayed:

1980-05-17 The Empire Strikes Back
1983-05-25 Return of the Jedi
1999-05-19...
