You haven’t imported StandardCharsets.
So either import java.nio.charset.StandardCharsets or replace it with utf-8.

However, I am sure you are gonna ask few more questions because your code wouldn’t work at all.
So I suggest you to check Web component’s source before creating any network related extension.
