Method Summary

Modifier and Type Method and Description
java.util.concurrent.CompletableFuture<IAuthenticationResult> acquireToken(ClientCredentialParameters parameters)

Acquires tokens from the authority configured in the application, for the confidential client itself.
java.util.concurrent.CompletableFuture<IAuthenticationResult> acquireToken(OnBehalfOfParameters parameters)

Acquires an access token for this application (usually a Web API) from the authority configured in the application, in order to access another downstream protected Web API on behalf of a user using the On-Behalf-Of flow.

Field Details

appTokenProvider

public Function<>> appTokenProvider

AppTokenProvider creates a Credential from a function that provides access tokens. The function must be concurrency safe. This is intended only to allow the Azure SDK to cache MSI tokens. It isn't useful to applications in general because the token provider must implement all authentication logic.

Method Details

acquireToken

public CompletableFuture acquireToken(ClientCredentialParameters parameters)

Acquires tokens from the authority configured in the application, for the confidential client itself. It will by default attempt to get tokens from the token cache. If no tokens are found, it falls back to acquiring them via client credentials from the STS

Parameters:

parameters

acquireToken

public CompletableFuture acquireToken(OnBehalfOfParameters parameters)

Acquires an access token for this application (usually a Web API) from the authority configured in the application, in order to access another downstream protected Web API on behalf of a user using the On-Behalf-Of flow. It will by default attempt to get tokens from the token cache. This confidential client application was itself called with an acces token which is provided in the UserAssertion field of OnBehalfOfParameters.

When serializing/deserializing the in-memory token cache to permanent storage, there should be a token cache per incoming access token, where the hash of the incoming access token can be used as the token cache key. Access tokens are usually only valid for a 1 hour period of time, and a new access token in the UserAssertion means there will be a new token cache and new token cache key. To avoid your permanent storage from being filled with expired token caches, an eviction policy should be set. For example, a token cache that is more than a couple of hours old can be deemed expired and therefore evicted from the serialized token cache.
