Class CompositeAuthenticator

The CompositeAuthenticator uses a list of injected IAuthenticator to provide support for multiple authentication flows.

Inheritance
Object
CompositeAuthenticator
Inherited Members
Namespace: Unity.Cloud.Identity
Syntax
public class CompositeAuthenticator : ICompositeAuthenticator, IUrlRedirectionAuthenticator, IAuthenticator, IAccessTokenProvider, IAuthenticationStateProvider, IDisposable
Remarks

The CompositeAuthenticator uses internally the first IAuthenticator from the injected list that returns a true value when invoking method. Depending on the validated IAuthenticator, the authentication flow can require manual interaction with a UI. Use the value to decide if you need to enable manual login features.

Examples

Constructors

CompositeAuthenticator(CompositeAuthenticatorSettings)

Provides a ICompositeAuthenticator that accepts a CompositeAuthenticatorSettings to handle and prioritize runtime execution contexts.

Declaration
public CompositeAuthenticator(CompositeAuthenticatorSettings compositeAuthenticatorSettings)
Parameters
Type Name Description
CompositeAuthenticatorSettings compositeAuthenticatorSettings

A CompositeAuthenticatorSettings that contains the prioritized list of IAuthenticator.

Properties

AuthenticationState

Holds the current AuthenticationState.

Declaration
public AuthenticationState AuthenticationState { get; }
Property Value
Type Description
AuthenticationState
Implements

RequiresGUI

Whether the ICompositeAuthenticator implementation requires a graphical user interface (GUI) for the authentication flow.

Declaration
public bool RequiresGUI { get; }
Property Value
Type Description
Boolean
Implements
Remarks

A GUI is required for a user to click login and logout buttons and provide credentials when requested. When no GUI is required, the login is done automatically in the InitializeAsync() method.

Methods

CancelLogin()

Cancels the awaiting login operation.

Declaration
public void CancelLogin()
Implements
Exceptions
Type Condition
InvalidOperationException

Dispose()

Disposes IDisposable references.

Declaration
public void Dispose()
Implements

Dispose(Boolean)

Disposes IDisposable references internally.

Declaration
protected virtual void Dispose(bool disposing)
Parameters
Type Name Description
Boolean disposing

The Boolean value received from the public Dispose method.

GetAccessTokenAsync()

Declaration
public Task<string> GetAccessTokenAsync()
Returns
Type Description
Task<String>
Implements

HasValidPreconditionsAsync()

Indicates if the IAuthenticator has valid preconditions to provide authentication in the current execution context.

Declaration
public Task<bool> HasValidPreconditionsAsync()
Returns
Type Description
Task<Boolean>

A task that when completed indicates if the IAuthenticator has valid preconditions to provide authentication in the current execution context.
Implements
Remarks

The CompositeAuthenticator always returns false to prevent nested ICompositeAuthenticator architecture.

InitializeAsync()

A task to initialize the AuthenticationState from either cache or direct injection value.

Declaration
public async Task InitializeAsync()
Returns
Type Description
Task
Implements

LoginAsync()

Performs a login operation.

Declaration
public Task LoginAsync()
Returns
Type Description
Task

A task.
Implements
Exceptions
Type Condition
InvalidOperationException
AuthenticationFailedException

LogoutAsync(Boolean)

Performs a logout operation.

Declaration
public Task LogoutAsync(bool clearBrowserCache = false)
Parameters
Type Name Description
Boolean clearBrowserCache

An optional boolean value that, if set to true, triggers a navigation to the OS default browser to clear any cached session.
Returns
Type Description
Task

A task.
Implements
Remarks

A logout operation clears the user session in the application only. Unless the user manually clears the session in the browser that is used for authentication, a user can get automatically logged in again from cached values, without entering any credentials. Use the clearBrowserCache boolean to also clear the session in the browser to prevent automatic login from a cached session.

Exceptions
Type Condition
InvalidOperationException

Events

AuthenticationStateChanged

Triggers when the AuthenticationState of the current user changes.

Declaration
public event Action<AuthenticationState> AuthenticationStateChanged
Event Type
Type Description
Action<AuthenticationState>
Implements
Remarks

Subscribers of this event should restrict or allow access to available resources and features based on the returned value.
