GraphQLControllerBase::resolve_request_principal │ private │ WC 1.0

Resolve the request principal once per HTTP request.

Invoked eagerly at the top of {@see self::process_request()}, so a principal resolver throwing ApiException{} fails the request before any resolver runs (single coded error in the response, no data).

The principal is never null — anonymous requests are signalled by a principal whose authentication state is unauthenticated (for the default Principal{}, that's Principal::$user->ID === 0). Plugin resolvers can also signal "invalid credentials" by throwing ApiException.

The configured resolver's resolve_principal() may declare its \WP_REST_Request parameter or omit it; the autogenerated subclass overrides {@see self::principal_resolver_takes_request()} so this call uses the right arity without runtime reflection.

Method of the class: GraphQLControllerBase{}

No Hooks.

Returns

null. Nothing (null).

Usage

// private - for code of main (parent) class only
$result = $this->resolve_request_principal( $request ): object;
$request(WP_REST_Request) (required)
The incoming REST request.
