openiddict-access-token-management

Automatic token management for machine to machine and user-centric web app OAuth and OIDC flows

The project is highly inspired by Duende.AccessTokenManagement (refactored to work with OpenIddictClientService)

Client credentials

Setup

services.AddOpenIddict()

    // Register the OpenIddict client components.
    .AddClient(options =>
    {
        // Allow grant_type=client_credentials to be negotiated.
        options.AllowClientCredentialsFlow();

        // Disable token storage, which is not necessary for non-interactive flows like
        // grant_type=password, grant_type=client_credentials or grant_type=refresh_token.
        options.DisableTokenStorage();

        // Register the System.Net.Http integration and use the identity of the current
        // assembly as a more specific user agent, which can be useful when dealing with
        // providers that use the user agent as a way to throttle requests (e.g Reddit).
        options.UseSystemNetHttp()
               .SetProductInformation(typeof(Program).Assembly);

        // Add a client registration matching the client application definition in the server project.
        options.AddRegistration(new OpenIddictClientRegistration
        {
            Issuer = new Uri("https://localhost:44385/", UriKind.Absolute),

            ClientId = "console",
            ClientSecret = "388D45FA-B36B-4988-BA59-B187D329C207"
        });
    });

// default cache
services.AddDistributedMemoryCache();

services.AddClientAccessTokenManagement(options => {
    // or leave it empty and set options.DisableAccessTokenEncryption() on server
    options.EncryptionKey = "DRjd/GnduI3Efzen9V9BvbNUfc/VKgXltV7Kbk9sMkY=";
});

HTTP Client Factory

services.AddClientAccessHttpClient("invoices", "invoice.client", client =>
{
    client.BaseAddress = new Uri("https://apis.company.com/invoice/");
});

services.AddHttpClient<CatalogClient>(client =>
    {
        client.BaseAddress = new Uri("https://apis.company.com/catalog/");
    })
    .AddClientAccessTokenHandler("catalog.client");

Refresh token and cookie on the server have expired

services.AddUserAccessTokenManagement(options => {
    // or leave it empty and set options.DisableAccessTokenEncryption() on server
    options.UseUnauthorizedMiddleware = true;
    // redirect to login
    options.UnauthorizedRedirectOptions.RelativeUri = "/login";

    options.UnauthorizedRedirectOptions.AppendReturnUrlToQuery = true;
    // change returnUrl query name, default is 'returnUrl'
    options.UnauthorizedRedirectOptions.ReturnUrlQueryName = "myReturnUrlQueryName";

or same

services.AddClientAccessTokenManagement(options => ...);

Middleware

app.UseMiddleware<UnauthorizedMiddleware>();
