IdentityServer4 custom AuthorizeInteractionResponseGenerator

IdentityServer4 custom AuthorizeInteractionResponseGenerator

In IdentityServer4, the AuthorizeInteractionResponseGenerator is responsible for generating responses to user authorization requests, such as login or consent prompts. You can create a custom implementation of this class to provide your own logic for generating these responses.

To create a custom AuthorizeInteractionResponseGenerator, you need to implement the IAuthorizeInteractionResponseGenerator interface and register it with IdentityServer4. Here are the steps to do this:

  • Implement the IAuthorizeInteractionResponseGenerator interface:
public class CustomAuthorizeInteractionResponseGenerator : IAuthorizeInteractionResponseGenerator { // Implement the interface methods }
  • In the ProcessInteractionAsync method of your implementation, you can provide your own logic for generating responses to user authorization requests. Here's an example that generates a custom response for a specific client:
public class CustomAuthorizeInteractionResponseGenerator : IAuthorizeInteractionResponseGenerator { public async Task<InteractionResponse> ProcessInteractionAsync(ValidatedAuthorizeRequest request, ConsentResponse consent = null) { // Check if this is a request from a specific client if (request.Client.ClientId == "my-client-id") { // Generate a custom response return new InteractionResponse { IsError = true, Error = "custom_error", ErrorDescription = "This is a custom error message." }; } // If this is not a request from the specific client, use the default implementation return await Task.FromResult<InteractionResponse>(null); } }

In this example, we check if the request is from a specific client by comparing the client ID to a hardcoded value. If it is, we generate a custom response that indicates an error occurred. Otherwise, we return null to use the default implementation.

  • Register your custom implementation with IdentityServer4 in the ConfigureServices method of your Startup class:
services.AddTransient<IAuthorizeInteractionResponseGenerator, CustomAuthorizeInteractionResponseGenerator>();

This registers your custom implementation with the DI container so it can be used by IdentityServer4.

With these steps, you can create a custom AuthorizeInteractionResponseGenerator to provide your own logic for generating responses to user authorization requests.
