如何初始化reactor HttpClient的基本鉴权头部？

import reactor.netty.http.client.HttpClient;
import reactor.netty.http.client.HttpClientRequest;
import java.nio.charset.StandardCharsets;
import java.util.Base64;

HttpClient httpClient = HttpClient.create();

String username = "your_username";
String password = "your_password";
String credentials = username + ":" + password;
String encodedCredentials = Base64.getEncoder().encodeToString(credentials.getBytes(StandardCharsets.UTF_8));

httpClient.headers(headers -> headers.set("Authorization", "Basic " + encodedCredentials));

httpClient.get()
    .uri("https://example.com/api")
    .response()
    .block();
