public class JwtHeaderInjecter
extends java.lang.Object
implements javax.ws.rs.client.ClientRequestFilter
These jax-rs client request filter APIs retrieve the JWT token from the
subject on the thread or self issue a JWT token and then adds the token to
the jax-rs client request header to propagate the JWT token.
The code snippet that is shown here demonstrate how to use these APIs to
propagate the token.
// 1. Create a jax-rs client javax.ws.rs.client.Client client = javax.ws.rs.client.ClientBuilder.newClient(); // 2. Register the jwt client request filter api using one of the three ways shown here client.register(new JwtHeaderInjecter()); or client.register(new JwtHeaderInjecter("customHeader")); or client.register(new JwtHeaderInjecter("customHeader","jwtBuilder")); // 3. Make REST request - The jwt token from the subject on the thread will be added to the default header "Authorization" or to the custom header String response = client.target(requesturl).request("text/plain").get(String.class)
