Plexus component which can itself have a reference to the host application in order to perform its work. This may not occur in the first versions of the plugin API but a resource needs to simply become the mapping mechanism by which parameters are taken from the REST side of the application and mapped into a method call within a given Plexus component. Whether that be the core Nexus application or a component provided by a plugin.

At the very least in the short term the resource needs to...

        System.arraycopy(err, 0, buf, bodyStart + 8, bc);

        int decoded = resp.decode(buf, headerStart);
        assertTrue(decoded > 0);

        // When error path is taken, no blob should be parsed
        assertNull(resp.getBlob(), "Blob should be null on error path");
        assertNotNull(resp.getErrorData(), "Error data should be present");
        assertArrayEquals(err, resp.getErrorData());

But that will only allow certain types of communication, excluding everything that involves credentials: Cookies, Authorization headers like those used with Bearer Tokens, etc.

So, for everything to work correctly, it's better to specify explicitly the allowed origins.

## Use `CORSMiddleware` { #use-corsmiddleware }

     * Performs MAC signing of the SMB.  This is done as follows.
     * The signature field of the SMB is overwritted with the sequence number;
     * The MD5 digest of the MAC signing key + the entire SMB is taken;
     * The first 8 bytes of this are placed in the signature field.
     *
     * @param data The data.
     * @param offset The starting offset at which the SMB header begins.

Aber das erlaubt nur bestimmte Arten der Kommunikation und schließt alles aus, was Anmeldeinformationen beinhaltet: Cookies, Autorisierungsheader wie die, die mit Bearer Tokens verwendet werden, usw.

Um sicherzustellen, dass alles korrekt funktioniert, ist es besser, die erlaubten Origins explizit anzugeben.
