GenHTTP.Modules.Webservices

The webservice module provides an easy way to implement RESTful services that can be consumed by clients as needed.

ℹī¸
Webservices can quickly be created by using a project template.

Hosting an API

To host an API using this framework you can define a new class that hosts your operations as dedicated methods. The signature of those methods will define how your API can be called via HTTP.

The following example shows how to define and host a service that can be used to manage an entity (books in this case).

using GenHTTP.Engine.Internal;

using GenHTTP.Api.Protocol;

using GenHTTP.Modules.Webservices;
using GenHTTP.Modules.Security;
using GenHTTP.Modules.Layouting;

public class BookService
{

    // GET http://localhost:8080/books/?page=1&pageSize=20
    [ResourceMethod]
    public List<Book> GetBooks(int page, int pageSize) { /* ... */ }

    // GET http://localhost:8080/books/4711
    [ResourceMethod(":id")]
    public Book? GetBook(int id) { /* ... */ }

    // PUT http://localhost:8080/books/
    [ResourceMethod(RequestMethod.PUT)]
    public Book AddBook(Book book) { /* ... */ }

    // POST http://localhost:8080/books/
    [ResourceMethod(RequestMethod.POST)]
    public Book UpdateBook(Book book) { /* ... */ }

    // DELETE http://localhost:8080/books/4711
    [ResourceMethod(RequestMethod.DELETE, ":id")]
    public Book? DeleteBook(int id) { /* ... */ }

}

var service = Layout.Create()
                    .AddService<BookService>("books")
                    .Add(CorsPolicy.Permissive());

await Host.Create()
          .Handler(service)
          .Development()
          .Console()
          .RunAsync();
