Adding OAuth2 authentication flow

Blackbird can support apps that require OAuth2 connections. Currently Blackbird supports the following standard flows:

• Authorization code (Section 1.3.1 of RFC )
• Implicit grant (Section 1.3.2 of RFC )

To get started, implement interfaces for IOAuth2AuthorizeService and IOAuth2TokenService.

Then add references to these interfaces in your IApplication.

When the OAuth2 flow is started, Blackbird calls instances of the IOAuth2AuthorizeService and IOAuth2TokenService using the GetInstance<T> method of the IApplication interface. You should implement logic to return instances of these interfaces.

Let’s see a simple implementation example:

public class SampleApplication : IApplication
{
  private readonly Dictionary<Type, object> _container;
  public string Name => "Sample Application";

  public SampleApplication()
  {
    _container = LoadTypes();
  }

  public T GetInsance<T>()
  {
    return _container[typeof(T)] as T;
  }

  private Dictionary<Type, object> LoadTypes()
  {
    new Dictionary<Type, object>
    {
      new { IOAuth2AuthorizeService, new OAuth2AuthorizeService() },
      new { IOAuth2TokenService, new OAuth2TokenService() }
    }
  }
}
