Using CustomCredentialsAuthProvider in JsonServiceClient - servicestack

Question

I try to implement my own custom CredentialsAuthProvider. The server seems to work fine with the following implementation:
public class MyCustomCredentialsAuthProvider : CredentialsAuthProvider
{
public override bool TryAuthenticate(IServiceBase authService, string userName, string password)
{
if (userName == "testuser" && password == "1234")
{
return true;
}
else
{
return false;
}
}
public override IHttpResult OnAuthenticated(IServiceBase authService, IAuthSession session, IAuthTokens tokens,
Dictionary<string, string> authInfo)
{
session.FirstName = "Testuser Joe Doe";
authService.SaveSession(session, SessionExpiry);
return null;
}
}
When I call on my Browser http://localhost:8088/auth/credentials?UserName=testuser&Password=1234 I get back a page containing a session ID and the testuser Joe Doe. Looks fine.
Now I try to call this from my Windows WPF client. I have created a Login Page and a LoginViewModel class since I implement the MVVM pattern. But I do not understand, what I really have to set the provider property in the Authenticate class to.
In my WPF class I have the following:
public partial class App : Application
{
public JsonServiceClient ServiceClient { get; private set; }
public App()
{
this.InitializeComponent();
}
// ....
}
And then in my LoginViewModel I have a Login() method which is a RelayCommand implementation of the login button like so (The form contains also a field where you have to enter the name of the application server since there is more than one. This is why I compose the baseUri in the handler):
private void Login()
{
var baseUri = $"http://{AppServer}:8088";
((App)Application.Current).InitServiceClient(baseUri);
var client = ((App) Application.Current).ServiceClient;
//var response = client.Send<AuthResponse>(new Auth { UserName = "Test", Password = "TestPassword" });
var authResponse = client.Post(new Authenticate
{
provider = CredentialsAuthProvider.Name, // <-- WHAT SHOULD THIS BE???
UserName = "testuser",
Password = "1234",
RememberMe = true,
});
// ....
}
CredentialsAuthProvider is unknown by the compiler. What do I need to pass here and what assemblies do I need? So far I have:
ServiceStack.Ckient
ServiceStack.Interfaces
ServiceStack.Text
MyService.ServiceModel //DLL containing the DTOs etc., NO implementations
What am I missing and doing wrong here?

CredentialsAuthProvider.Name just provides typed access to the "credentials" string literal, which you can use in its place, e.g:
var authResponse = client.Post(new Authenticate
{
provider = "credentials",
UserName = "testuser",
Password = "1234",
RememberMe = true,
});
You can find the list of Auth provider literals in the Authentication docs.
