Estou tentando usar spring-boot-starter-oauth2-client com o novo Spring Framework release 6 HttpInterface
@Configuration
public class RestClientConfig {
@Bean
public RestClient restClient(OAuth2AuthorizedClientManager authorizedClientManager, RestClient.Builder restClientBuilder) {
OAuth2ClientHttpRequestInterceptor interceptor = new OAuth2ClientHttpRequestInterceptor(authorizedClientManager);
return restClientBuilder
.requestInterceptor(interceptor)
.build();
}
}
@RestController
public class LessonsController {
private final RestClient restClient;
public LessonsController(RestClient restClient) {
this.restClient = restClient;
}
@GetMapping("/lessons")
public String fetchLessons() {
return restClient.get()
.uri("https://someserver.om/someprotectedresource")
.attributes(clientRegistrationId("my-client"))
.retrieve()
.body(String.class);
}
}
spring:
application:
name: client-application
security:
oauth2:
client:
registration:
my-client:
provider: my-provider
client-id: ididid
client-secret: secretsecret
authorization-grant-type: client_credentials
scope: download
provider:
my-provider:
token-uri: https://provider.com/token
O acima está funcionando. Temos a confirmação do provedor de token de que obtivemos o token, assim como do servidor de recursos de que obtivemos o recurso, passando o token. Ambas as duas etapas estão funcionando bem, feliz.
https://www.youtube.com/watch?v=aR580OCEp7w Agora gostaríamos de fazer o mesmo, com a nova versão 6 do Spring Framework HttpInterface
Ao fazer isso:
@Configuration
public class UserClientConfig {
private final RestClient restClient;
public UserClientConfig(OAuth2AuthorizedClientManager authorizedClientManager, RestClient.Builder restClientBuilder) {
OAuth2ClientHttpRequestInterceptor interceptor = new OAuth2ClientHttpRequestInterceptor(authorizedClientManager);
this.restClient = restClientBuilder
.requestInterceptor(interceptor)
.baseUrl("https://host.com")
.build();
}
@Bean
public UserClient userClient() {
RestClientAdapter adapter = RestClientAdapter.create(restClient);
return HttpServiceProxyFactory.builderFor(adapter)
.build()
.createClient(UserClient.class);
}
}
@HttpExchange(
url = "/v1",
accept = MediaType.APPLICATION_JSON_VALUE)
public interface UserClient {
@GetExchange("/protectedresource/full")
public User getUserById(@RequestParam Map<String, String> key value);
}
@GetMapping("/lessons")
public User fetchLessons() {
return userClient.getUserById(Map.of("foo", "bar"));
}
Ao usar HttpInterface, isso não funcionaria. O token não é buscado em primeiro lugar. Talvez por causa da falta de .attributes(clientRegistrationId("id")) para @HttpExchange @GetExchange, mas não tenho certeza.
Pergunta: como combinar a interface HTTP com o token spring-boot-starter-oauth2-client?
