POServiceStack authentication request fails
text
Body
copied!<p>I am trying to set up authentication with my ServiceStack service by following <a href="http://enehana.nohea.com/general/customizing-iauthprovider-for-servicestack-net-step-by-step/" rel="nofollow">this tutorial</a>.</p> <p>My service is decorated with the <code>[Authenticate]</code> attribute.</p> <p>My AppHost looks like this:</p> <pre><code>public class TestAppHost : AppHostHttpListenerBase { public TestAppHost() : base("TestService", typeof(TestService).Assembly) { } public static void ConfigureAppHost(IAppHost host, Container container) { try { // Set JSON web services to return idiomatic JSON camelCase properties. ServiceStack.Text.JsConfig.EmitCamelCaseNames = true; // Configure the IOC container IoC.Configure(container); // Configure ServiceStack authentication to use our custom authentication providers. var appSettings = new AppSettings(); host.Plugins.Add(new AuthFeature(() => new AuthUserSession(), // use ServiceStack's session class but fill it with our own data using our own auth service provider new IAuthProvider[] { new UserCredentialsAuthProvider(appSettings) })); } } </code></pre> <p>where <code>UserCredentialsAuthProvider</code> is my custom credentials provider:</p> <pre><code>public class UserCredentialsAuthProvider : CredentialsAuthProvider { public override bool TryAuthenticate(IServiceBase authService, string userName, string password) { try { // Authenticate the user. var userRepo = authService.TryResolve<IUserRepository>(); var user = userRepo.Authenticate(userName, password); // Populate session properties. var session = authService.GetSession(); session.IsAuthenticated = true; session.CreatedAt = DateTime.UtcNow; session.DisplayName = user.FullName; session.UserAuthName = session.UserName = user.Username; session.UserAuthId = user.ID.ToString(); } catch (Exception ex) { // ... Log exception ... return false; } return true; } } </code></pre> <p>In my user tests I initialize and start my TestAppHost on <code>http://127.0.0.1:8888</code>, then use JsonServiceClient to authenticate itself to the service like so:</p> <pre><code>var client = new JsonServiceClient("http://127.0.0.1:8888/") var response = client.Send<AuthResponse>(new Auth { provider = UserCredentialsAuthProvider.Name, UserName = username, Password = password, RememberMe = true }); </code></pre> <p>But getting the following exception:</p> <pre><code>The remote server returned an error: (400) Bad Request. at System.Net.HttpWebRequest.GetResponse() at ServiceStack.ServiceClient.Web.ServiceClientBase.Send[TResponse](Object request)... </code></pre> <p>The <code>ServiceStack.ServiceInterface.Auth.Auth</code> request contains the correct username and passsword, and the request is being posted to: </p> <pre><code>http://127.0.0.1:8888/json/syncreply/Auth </code></pre> <p>I am not sure why the URL is not <code>/json/auth/credentials</code> or what I might be doing wrong. Any suggestions?</p> <p><hr> <strong>UPDATE</strong></p> <p>Tracing the chain of events up the stack I found the following:</p> <p><code>JsonDataContractSerializer.SerializeToStream</code> correctly serializes the Auth request into Json. However, the <code>System.Net.HttpRequestStream</code> passed to <code>JsonDataContractDeserializer</code> by <code>EndpointHandlerBase</code> has a stream of the correct length that is filled with nulls (zero bytes). As a result, the request object passed to <code>CredentialsAuthProvider.Authenticate</code> has nulls in all its properties.</p> <p>How can the HTTP stream get stripped of its data?</p>

Querying!
