[英]How can I login to remote webservice from spring boot feign client
嗨,我是新来的假装客户和outh2。 我正在使用Spring Boot 1.5.6。 我想登录我没有写的远程网络服务。 该Web服务使用outh2。 我想将访问令牌从该Web服务获取到我的伪装客户端。
我的假客户喜欢:
@FeignClient(name = "feignclient", url ="BASE_URL" )
public interface FeignGateAway{
@RequestMapping(method = RequestMethod.POST, value = "BASE_URL/oauth/token?"
+ "client_id=client_id"
+ "&client_secret=client_sercret"
+ "&username=email"
+ "&password=password"
+ "&grant_type=password"
+ "&redirect_uri=urn:ietf:wg:oauth:2.0:oob")
Object login();
}
当我发送请求时,出现此错误:
com.netflix.client.ClientException:负载平衡器没有适用于客户端的服务器:feignGateAway
您将oauth配置添加到伪装中

*/
@AliasFor(annotation = FeignClient.class, attribute = "configuration")
Class<?>[] configuration() default OAuth2InterceptedFeignConfiguration.class;
/**

*/
String url() default "";

boolean decode404() default false;
/**

Class<?> fallback() default void.class;

String path() default "";
}
@Configuration
public class OAuth2InterceptedFeignConfiguration {
private JHipsterProperties jHipsterProperties;
private LoadBalancerClient loadBalancerClient;
@Bean(name = "oauth2RequestInterceptor")
public RequestInterceptor getOAuth2RequestInterceptor() throws IOException {
if (loadBalancerClient != null) {
jHipsterProperties.getSecurity().getClientAuthorization().setLoadBalancerClient(loadBalancerClient);
}
return new OAuth2FeignRequestInterceptor(
new DefaultOAuth2ClientContext(), jHipsterProperties.getSecurity().getClientAuthorization()
);
}
@Inject
public void setjHipsterProperties(JHipsterProperties jHipsterProperties) {
this.jHipsterProperties = jHipsterProperties;
}
@Autowired(required = false)
public void setLoadBalancerClient(LoadBalancerClient loadBalancerClient) {
this.loadBalancerClient = loadBalancerClient;
}
}
并把假装客户变成这样
@AuthorizedFeignClient(name = "notification-service")
public interface NotificationServiceClient {
@RequestMapping(path = "notifications/email/send", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_UTF8_VALUE)
public void sendMail(@RequestParam("to") String to, @RequestParam("subject") String subject, @RequestParam("body") String body);
}
