RequestObjectFetcher Class

Abblix.Oidc.Server​

Abblix.Oidc.Server.Features.RequestObject​

RequestObjectFetcher Class​

Provides functionality to validate and process JWT request objects, binding their payloads to a request model. This class is typically used in OpenID Connect flows where request parameters are passed as JWTs.

public class RequestObjectFetcher : Abblix.Oidc.Server.Features.RequestObject.IRequestObjectFetcher

Inheritance System.Object → RequestObjectFetcher

Implements IRequestObjectFetcher

Constructors​

RequestObjectFetcher(ILogger<RequestObjectFetcher>, IJsonObjectBinder, IServiceProvider, IOptionsSnapshot<OidcOptions>) Constructor​

Provides functionality to validate and process JWT request objects, binding their payloads to a request model. This class is typically used in OpenID Connect flows where request parameters are passed as JWTs.

public RequestObjectFetcher(Microsoft.Extensions.Logging.ILogger<Abblix.Oidc.Server.Features.RequestObject.RequestObjectFetcher> logger, Abblix.Oidc.Server.Common.Interfaces.IJsonObjectBinder jsonObjectBinder, System.IServiceProvider serviceProvider, Microsoft.Extensions.Options.IOptionsSnapshot<Abblix.Oidc.Server.Common.Configuration.OidcOptions> options);

Parameters​

logger Microsoft.Extensions.Logging.ILogger<RequestObjectFetcher>​

The logger for recording debug information and warnings.

jsonObjectBinder IJsonObjectBinder​

The binder for converting JSON payloads into request objects.

serviceProvider System.IServiceProvider​

The service provider used for resolving dependencies at runtime.

options Microsoft.Extensions.Options.IOptionsSnapshot<OidcOptions>​

Options that define how request object validation is handled, including whether request objects must be signed.

Methods​

RequestObjectFetcher.FetchAsync<T>(T, string, Func<ClientInfo,string>) Method​

Fetches and processes the request object by validating its JWT and binding the payload to the request model.

public System.Threading.Tasks.Task<Abblix.Utils.Result<T,Abblix.Oidc.Server.Common.OidcError>> FetchAsync<T>(T request, string? requestObject, System.Func<Abblix.Oidc.Server.Features.ClientInformation.ClientInfo,string?>? requiredSigningAlgorithm=null)
    where T : class;

Type parameters​

T​

The type of the request model.

Parameters​

request T​

The initial request model to bind the JWT payload to.

requestObject System.String​

The JWT contained within the request, if any.

requiredSigningAlgorithm System.Func<ClientInfo,System.String>​

An optional selector returning the signing algorithm the request object must use for a given client, or null to impose no per-client requirement.

Implements FetchAsync<T>(T, string, Func<ClientInfo,string>)

Returns​

System.Threading.Tasks.Task<Abblix.Utils.Result<T,OidcError>>
A task representing the asynchronous operation. The task result contains an Abblix.Utils.Result<> which either represents a successfully processed request or an error indicating issues with the JWT validation.

Remarks​

This method is used to decode and validate the JWT contained in the request. If the JWT is valid, the payload is bound to the request model. If the JWT is invalid, an error is returned and logged.
