Update OnBeforeTokenAcquisitionForOnBehalfOf event to construct ClaimsPricipal from token#3714
Conversation
…ipal from token In PR #3712 changed the usage of user to userHint, but based on the logic at the beginning of the changed method, the single source of truth in terms of OBO shall be derived from tokenUsedToCallTheWebApi. This change constructs a ClaimsPrincipal from the token string and preserves the BootstrapContext for use in event handlers.

This pull request introduces a new
OnBehalfOfEventArgsclass to provide richer context for on-behalf-of token acquisition events and updates the related public API signatures to use this new class instead of passing aClaimsPrincipaldirectly. This change improves extensibility and clarity for event handlers involved in token acquisition flows.Key changes:
API Enhancements:
OnBehalfOfEventArgsclass, which encapsulates the user (ClaimsPrincipal) and the user assertion token, providing additional context for on-behalf-of token acquisition operations. (src/Microsoft.Identity.Web.TokenAcquisition/OnBehalfOfEventArgs.cs, src/Microsoft.Identity.Web.TokenAcquisition/OnBehalfOfEventArgs.csR1-R27)OnBehalfOfEventArgsclass and its properties. (src/Microsoft.Identity.Web.TokenAcquisition/PublicAPI/net8.0/PublicAPI.Unshipped.txt,src/Microsoft.Identity.Web.TokenAcquisition/PublicAPI/net9.0/PublicAPI.Unshipped.txt,src/Microsoft.Identity.Web.TokenAcquisition/PublicAPI/net10.0/PublicAPI.Unshipped.txt,src/Microsoft.Identity.Web.TokenAcquisition/PublicAPI/net462/PublicAPI.Unshipped.txt,src/Microsoft.Identity.Web.TokenAcquisition/PublicAPI/net472/PublicAPI.Unshipped.txt, src/Microsoft.Identity.Web.TokenAcquisition/PublicAPI/net10.0/PublicAPI.Unshipped.txtR4-R13)Breaking Changes to Event Handler Signatures:
BeforeTokenAcquisitionForOnBehalfOf.Invokeand its async counterpart to accept anOnBehalfOfEventArgsinstance instead of aClaimsPrincipal, across all relevant API files. This affects both synchronous and asynchronous event hooks.TokenAcquisitionExtensionOptions.InvokeOnBeforeTokenAcquisitionForOnBehalfOfand its async version to useOnBehalfOfEventArgsinstead ofClaimsPrincipal.These changes collectively make the token acquisition event handling more robust and future-proof by encapsulating relevant data in a dedicated event args class.PR #3712 changed the usage of user to userHint, but based on the logic at the beginning of the affected method, the single source of truth in terms of OBO shall be derived from tokenUsedToCallTheWebApi. This change constructs a ClaimsPrincipal from the token string.
