如何在webflux安全的webclient上添加HTTP.POST和HTTP.PUT的HTTP基本身份验证？

implementation 'org.springframework.boot:spring-boot-starter-webflux'
implementation 'org.springframework.boot:spring-boot-starter-security'

@Configuration
@EnableWebFluxSecurity
public class SecurityConfig {

    @Bean
    public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) {
        return http
                .authorizeExchange()
                .pathMatchers(HttpMethod.POST, "/api/**").authenticated()
                .pathMatchers(HttpMethod.PUT, "/api/**").authenticated()
                .anyExchange().permitAll()
                .and()
                .httpBasic()
                .and()
                .build();
    }
}

@Bean
public WebClient webClient() {
    return WebClient.builder()
            .filter(basicAuthentication("username", "password"))
            .build();
}

@Autowired
private WebClient webClient;

public Mono<String> postData() {
    return webClient.post()
            .uri("https://example.com/api/endpoint")
            .bodyValue("data")
            .retrieve()
            .bodyToMono(String.class);
}

public Mono<String> putData() {
    return webClient.put()
            .uri("https://example.com/api/endpoint")
            .bodyValue("data")
            .retrieve()
            .bodyToMono(String.class);
}
