How to use Spring Boot feign client for Oauth2 authentication?

问题

我在本地有一个 OAuth 服务器，并希望从另一个服务使用 Feign 客户端调用它，以对我进行身份验证并提供一些令牌。

这是我在 Postman 中如何传递用户名、密码和授权类型的方式

这是我如何传递基本身份验证详细信息的方式

如何在 Spring Boot 中使用 Feign 客户端实现相同的功能？

英文:

I have an oauth server at localhost and want to call it from another service uisng feign-client for authenticating me and giving me some token.

Here is how i pass my username,password and grant type i postman

Here is how my pass the basic auth details

How to do the same functionality using FeignClient in Spring Boot?

将@EnableFeignClients注解放置在Spring Boot主应用程序的Java类中。
创建一个Feign客户端接口来调用Web服务：

  1. @FeignClient(value = "service-auth",
  2.     configuration = ClientConfig.class,
  3.     fallbackFactory = ClientFallbackFactory.class,
  4.     url = "http://localhost:10000/oauth/")
  5. public interface GenericAbstractClient {
  7.     @RequestMapping(value="/token",
  8.             method = RequestMethod.POST,
  9.             consumes = MediaType.APPLICATION_JSON_UTF8_VALUE,
  10.             produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
  11.     ResponseVo auth(@RequestBody RequestVo body);
  12. }

以及ClientFallbackFactory类：

  1. @Component
  2. class ClientFallbackFactory implements FallbackFactory<GenericAbstractClient> {
  4.     private static final Logger LOGGER = LoggerFactory.getLogger(ClientFallbackFactory.class);
  6.     @Override
  7.     public GenericAbstractClient create(Throwable cause) {
  9.         return new GenericAbstractClient() {
  11.             @Override
  12.             public ResponseVo auth(RequestVo body) {
  13.                 LOGGER.warn("Hystrix exception", cause.getMessage());
  14.                 return null;
  15.             }
  16.         };
  17.     }
  18. }

你的RequestBody可能是一个Java类：

  1. @Data
  2. @NoArgsConstructor
  3. @AllArgsConstructor
  4. @Builder
  5. public class RequestVo {
  7.     private String grant_type;
  8.     private String username;
  9.     private String password;
  10. }

以及ResponseVo类：

  1. @Data
  2. @NoArgsConstructor
  3. @AllArgsConstructor
  4. @Builder
  5. public class ResponseVo {
  7.     private String access_token;
  8.     private String token_type;
  9.     private String expires_in;
  10.     private String scope;
  11. }

你还可以添加以下配置：

  1. @Configuration
  2. public class ClientConfig {
  4.     private int connectTimeOutMillis = 120000;
  5.     private int readTimeOutMillis = 120000;
  7.     @Bean
  8.     public Request.Options options() {
  9.         return new Request.Options(connectTimeOutMillis, readTimeOutMillis);
  10.     }
  11. }

这是你提供的内容的翻译部分。

英文:

put @EnableFeignClients in the spring boot main application java class .
create after an Feign client interface to call the web service :

  1.     @FeignClient(value = &quot;service-auth&quot;,
  2.         configuration = ClientConfig.class,
  3.         fallbackFactory = ClientFallbackFactory.class,
  4.         url = &quot;http://localhost:10000/oauth/&quot;)
  5.     public interface GenericAbstractClient {
  8.     @RequestMapping(value=&quot;/token&quot;,
  9.             method = RequestMethod.POST,
  10.             consumes = MediaType.APPLICATION_JSON_UTF8_VALUE,
  11.             produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
  12.     ResponseVo auth(@RequestBody RequestVo body);
  15. }

> and ClientFallbackFactory as :

  1.     @Component
  2.     class ClientFallbackFactory implements FallbackFactory&lt;GenericAbstractClient&gt; {
  4.     private static final Logger LOGGER = LoggerFactory.getLogger(ClientFallbackFactory.class);
  7.    
  9.      @Override
  10.       public GenericAbstractClient create(Throwable cause) {
  12.     return new GenericAbstractClient () {
  15.       @Override
  16.       public ResponseVo oauth(RequestVo body) {
  17.         LOGGER.warn(&quot;Hystrix exception&quot;, cause.getMessage());
  18.         return null;
  19.       }
  21.     
  22.     };
  23. }
  24. }

Your RequestBody might be a java class :

  1. @Data
  2. @NoArgsConstructor
  3. @AllArgsConstructor
  4. @Builder
  5. public class RequestVo {
  8. private String grant_type;
  9. private String username;
  10. private String password;

}

and The ResponseVo class :

  1.     @Data
  2. @NoArgsConstructor
  3. @AllArgsConstructor
  4. @Builder
  5. public class ResponseVo {
  8. private String access_token;
  9. private String token_type;
  10. private String exprires_in;
  11. private String scope;

}

and you can add thise config :

  1. @Configuration
  2. public class ClientConfig {
  5.     private int connectTimeOutMillis = 120000;
  6.     private int readTimeOutMillis = 120000;
  9.     @Bean
  10.     public Request.Options options() {
  11.         return new Request.Options(connectTimeOutMillis, readTimeOutMillis);
  12.     }
  13. }
