Spring Security OAuth 2:如何在OAuth /token请求后获得访问令牌和其他数据

Question

我正在使用Spring安全和Oauth 2.0认证协议来保护REST服务。

我已经实现了一个MVC Spring应用程序，它的工作很好。客户端通过提供客户端凭据(client_id &client_secret),用户凭证(username &(密码)调用定义在servlet-config.xml中的outh/token服务:

<http pattern="/oauth/token" create-session="stateless"
    authentication-manager-ref="clientAuthenticationManager"
    xmlns="http://www.springframework.org/schema/security" > 
    <intercept-url pattern="/oauth/token" access="IS_AUTHENTICATED_FULLY" />
    <anonymous enabled="false" />
    <http-basic entry-point-ref="clientAuthenticationEntryPoint" />
    <custom-filter ref="clientCredentialsTokenEndpointFilter" before="BASIC_AUTH_FILTER" /> 
    <access-denied-handler ref="oauthAccessDeniedHandler" />
 </http>

如果凭据是有效的，客户端将得到一个访问令牌，如下所示:

{
    "value": "b663f10d-553d-445b-afde-e9cd84066a1c",
    "expiration": 1406598295994,
    "tokenType": "bearer",
    "refreshToken": {
        "value": "36737abf-24bd-4b86-ad22-601f4d5cdee4",
        "expiration": 1408890295994
    },
    "scope": [],
    "additionalInformation": {},
    "expiresIn": 299999,
    "expired": false
}

我想有一个响应，也包含用户的详细信息，像这样:

{
        "value": "b663f10d-553d-445b-afde-e9cd84066a1c",
        "expiration": 1406598295994,
        "tokenType": "bearer",
        "refreshToken": {
            "value": "36737abf-24bd-4b86-ad22-601f4d5cdee4",
            "expiration": 1408890295994
        },
        "additionalInformation": {},
        "expiresIn": 299999,
        "expired": false,
        "USER_ID": "1",
        "USER_ROLE": "admin",
        "OTHER DATA..."
    }

有人知道实现这个的方法吗?

我一直在谷歌相当多，但我没有找到一个实现类似场景的例子。如果这个问题听起来很蠢，我很抱歉，但我是Spring Security的新手。

Answer 1

这就是我如何实现类似于您的场景。

1)创建自定义令牌增强器:

public class CustomTokenEnhancer implements TokenEnhancer {
    @Override
    public OAuth2AccessToken enhance(OAuth2AccessToken accessToken, OAuth2Authentication authentication) {
        final Map<String, Object> additionalInfo = new HashMap<>();
        User user = (User) authentication.getPrincipal();
        additionalInfo.put("user_id", user.getId());
        additionalInfo.put("business_id", user.getBusinessId());
        ((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(additionalInfo);
        return accessToken;
    }
}

2)用户自定义令牌增强器配置。

@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
    endpoints
        .tokenStore(tokenStore())
        .tokenEnhancer(tokenEnhancerChain())
        .authenticationManager(authenticationManager)
        .accessTokenConverter(jwtAccessTokenConverter());
}
/**
 * Creates a chain of the list of token enhancers.
 * @return
 * 
 * @since 0.0.1
 * 
 * @author Anil Bharadia
 */
public TokenEnhancerChain tokenEnhancerChain() {
    TokenEnhancerChain chain = new TokenEnhancerChain();
    chain.setTokenEnhancers(Arrays.asList(tokenEnhancer(), jwtAccessTokenConverter()));
    return chain;
}
/**
 * Get the new instance of the token enhancer.
 * @return
 */
@Bean
public TokenEnhancer tokenEnhancer() {
    return new CustomTokenEnhancer();
}

就是这样。下次请求令牌时，您将获得带有附加信息的令牌。

对于那些最近检查解决方案的人来说，这也是一个很好的解决方案。

@GetMapping("/token")
@ResponseBody
public String userinfo(@RegisteredOAuth2AuthorizedClient("${YOUR_CLIENT}") OAuth2AuthorizedClient authorizedClient) {
    return authorizedClient.getAccessToken().getTokenValue();
}
