API Reference

Getting Started

Install packages:

dotnet add package Keycloak.AuthServices.Authentication

// Program.cs
using Keycloak.AuthServices.Authentication;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddKeycloakWebApiAuthentication(builder.Configuration);
builder.Services.AddAuthorization();

var app = builder.Build();

app.UseAuthentication();
app.UseAuthorization();

app.MapGet("/", () => "Hello World!").RequireAuthorization();

app.Run();

In this example, configuration is based on appsettings.json.

//appsettings.json
{
 "Keycloak": {
 "realm": "Test",
 "auth-server-url": "http://localhost:8080/",
 "ssl-required": "none",
 "resource": "test-client",
 "verify-token-audience": false,
 "credentials": {
 "secret": ""
 },
 "confidential-port": 0
 }
}

Example - Add Authorization

With Keycloak.AuthServices.Authorization, you can implement role-based authorization in your application. This package allows you to define policies based on roles. Also, you can use Keycloak as Authorization Server. It is a powerful way to organize and apply authorization polices centrally.

var builder = WebApplication.CreateBuilder(args);

var host = builder.Host;
var configuration = builder.Configuration;
var services = builder.Services;

services.AddKeycloakWebApiAuthentication(configuration);

services.AddAuthorization(options =>
 {
 options.AddPolicy("AdminAndUser", builder =>
 {
 builder
 .RequireRealmRoles("User") // Realm role is fetched from token
 .RequireResourceRoles("Admin"); // Resource/Client role is fetched from token
 });
 })
 .AddKeycloakAuthorization(configuration);

var app = builder.Build();

app.UseAuthentication();
app.UseAuthorization();

app.MapGet("/hello", () => "[]")
 .RequireAuthorization("AdminAndUser");

app.Run();

Example - Invoke Admin API

var services = new ServiceCollection();
services.AddKeycloakAdminHttpClient(new KeycloakAdminClientOptions
{
 AuthServerUrl = "http://localhost:8080/",
 Realm = "master",
 Resource = "admin-api",
});

var sp = services.BuildServiceProvider();
var client = sp.GetRequiredService<IKeycloakRealmClient>();

var realm = await client.GetRealmAsync("Test");
