This directive does not implement the complete OAuth2 protocol, but instead enables implementing it, by extracting the needed token from the HTTP headers.
Refer to authenticateOAuth2 for a detailed description of this directive.
Its semantics are equivalent to
authenticateOAuth2PF ’s, where not handling a case in the Partial Function (PF) leaves the request to be rejected with a
See also authenticateOAuth2PF if the authorization operation is rather quick, and does not have to execute asynchronously.
See Credentials and password timing attacks for details about verifying the secret.
For more information on how OAuth2 works see RFC 6750.
Usage in code is exactly the same as authenticateBasicPFAsync, with the difference that one must validate the token as OAuth2 dictates (which is currently not part of Akka HTTP itself).
