Package io.debezium.server.http.jwt

Class JWTAuthenticator

java.lang.Object

io.debezium.server.http.jwt.JWTAuthenticator

All Implemented Interfaces:

Authenticator

public class JWTAuthenticator
extends Object
implements Authenticator

Implements the logic for authenticating against an endpoint supporting the JSON Web Tokens (JWT) scheme. Once authentication is successful, the authenticator can add the authentication details to the header of an HTTP request using a HTTPRequest.Builder instance. After the initial authentication is successful, additional authentication attempts will refresh the token.
