spring的oauth/token响应中不返回刷新令牌

Question

我正在尝试使用 spring boot 和 spring security 创建一个 Rest API。以下是我为获取授权令牌所做的代码更改的详细信息：-

1]授权服务器配置

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {



    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private TokenStore tokenStore;

    @Autowired
    private UserApprovalHandler userApprovalHandler;

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.tokenStore(tokenStore).userApprovalHandler(userApprovalHandler)
        .authenticationManager(authenticationManager);
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory().withClient("my-trusted-client")
                .authorizedGrantTypes("client_credentials", "password", "refresh_token" )
                .authorities("ROLE_CLIENT").scopes("read","write","trust")
                .secret("secret")
                .accessTokenValiditySeconds(5000)
                .refreshTokenValiditySeconds(6000).autoApprove(true);
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security.checkTokenAccess("isAuthenticated()");
    }
  @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }


    @Bean
    public TokenStore tokenStore() {
        return new InMemoryTokenStore();
    }

    @Bean
    @Autowired
    public TokenStoreUserApprovalHandler userApprovalHandler(TokenStore tokenStore){
        TokenStoreUserApprovalHandler handler = new TokenStoreUserApprovalHandler();
        handler.setTokenStore(tokenStore);
        handler.setRequestFactory(new DefaultOAuth2RequestFactory(clientDetailsService));
        handler.setClientDetailsService(clientDetailsService);
        return handler;
    }

    @Bean
    @Autowired
    public ApprovalStore approvalStore(TokenStore tokenStore) throws Exception {
        TokenApprovalStore store = new TokenApprovalStore();
        store.setTokenStore(tokenStore);
        return store;
    }

}

2]资源服务器配置

@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {

    private static final String RESOURCE_ID = "my_rest_api";

    @Override
    public void configure(ResourceServerSecurityConfigurer resources) {
        resources.resourceId(RESOURCE_ID).stateless(false);
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.headers().frameOptions().disable().and()
                .authorizeRequests()
                .antMatchers("/register").permitAll()
                .antMatchers("/ex/**").authenticated();
    }


}

3]方法安全配置

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true, proxyTargetClass = true)
public class MethodSecurityConfig extends GlobalMethodSecurityConfiguration {
    @SuppressWarnings("unused")
    @Autowired
    private OAuth2SecurityConfiguration securityConfig;

    @Override
    protected MethodSecurityExpressionHandler createExpressionHandler() {
        return new OAuth2MethodSecurityExpressionHandler();
    }
}

当我通过邮递员发出请求时，会返回以下响应：-

请求网址：-

http://localhost:8090/oauth/token?grant_type=client_credentials&username=sr7&password=aA$gm12

收到的回复：-

{
    "access_token": "6e55f38f-4aad-4e84-97d2-24b30d39bf5e",
    "token_type": "bearer",
    "expires_in": 4999,
    "scope": "read write trust"
}

请帮助我找出我在这里做错了什么，这导致我无法获得刷新令牌和响应。

提前致谢。

Answer 1

根据规范，在“客户端凭据”授予类型的情况下，您通常（“不应该”，使用规范术语）没有刷新令牌。引用@chenrui 的这个答案：

client_credentials OAuth 授予服务器机器对机器身份验证的需要，因此无需刷新令牌。

结果，在 Spring Security OAuth 中ClientCredentialsAccessTokenProvider，supportsRefresh返回false，refreshToken方法返回null。

在“客户端凭据”中，裸客户端的凭据用于获取访问令牌。
