Method Details

readAuthentication

public Authentication readAuthentication(ServerCall<?,?> call,
 Metadata headers)
                                  throws AuthenticationException

Description copied from interface: GrpcAuthenticationReader

Tries to read the Authentication information from the given call and metadata.

Note: Implementations are free to throw an AuthenticationException if no credentials could be found in the call. If an exception is thrown by an implementation then the authentication attempt should be considered as failed and no subsequent GrpcAuthenticationReaders should be called. Additionally, the call will fail as Status.UNAUTHENTICATED. If the call instead returns null, then the call processing will proceed unauthenticated.

Specified by:

readAuthentication in interface GrpcAuthenticationReader

Parameters:

call - The call to get that send the request.

headers - The metadata/headers as sent by the client.

Returns:

The authentication object or null if no authentication is present.

Throws:

AuthenticationException - If the authentication details are malformed or incomplete and thus the authentication attempt should be aborted.
