Spring OAuth2RestTemplate无法获得新的accessToken

标签： spring-security-oauth2 netflix-zuul spring-oauth2

我正在使用带有 authorization_code流和 @EnableZuulProxy 的spring-boot-oauth2。我跟随tut-spring-security-and-angular-js with oauth2中的示例。  为开发目的，我将 access_token_validty 设置为60秒。 Everythings工作正常，直到访问令牌仍然有效。但是当访问令牌过期时（我等了一会儿就过期了），我得到了例外，如下所示..

我使用的是spring-boot 1.5.4版，我还将OAuth2RestTemplate配置为this github问题。任何建议都会非常感激。

3 个答案:

答案 0 :(得分：0)

正在使用相同的教程并在实现访问令牌刷新时遇到同样的问题。 

Caused by: org.springframework.security.authentication.BadCredentialsException: Cannot obtain valid access token
    at org.springframework.cloud.security.oauth2.proxy.OAuth2TokenRelayFilter.getAccessToken(OAuth2TokenRelayFilter.java:99) ~[spring-cloud-security-1.2.1.RELEASE.jar:1.2.1.RELEASE]

具体 - 当我收到错误时，我的测试应用程序被修改为使用通常的令牌，而不是JWT，但我认为解决问题并不重要。

澄清问题：

1）为客户添加密码授予：

@Configuration
@EnableAuthorizationServer
protected static class AuthServerConfig
    extends AuthorizationServerConfigurerAdapter {

@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    clients.inMemory()
        .withClient("app0")
        .secret("secret0")
        .authorizedGrantTypes("authorization_code","refresh_token","password")
        .scopes("some_scope");
}

2）通过curl执行以下请求（可以使用postman或其他首选实用程序）

curl -X POST \
  http://localhost:9999/uaa/oauth/token \
  -H 'authorization: Basic YXBwMDpzZWNyZXQw' \
  -H 'content-type: multipart/form-data;' \
  -F grant_type=password \
  -F scope=some_scope \
  -F username=john \
  -F password=123

3）它返回

{
    "access_token": "cc5fff72-8f09-4770-87f5-f2237ce5978f",
    "token_type": "bearer",
    "refresh_token": "da55eb5c-6d31-4d70-9af8-bad8ce8a777f",
    "expires_in": 43199,
    "scope": "some_scope"
}

4）获取refresh_token的值并在下一个curl命令

中使用它 
curl -X POST \
  http://localhost:9999/uaa/oauth/token \
  -H 'authorization: Basic YXBwMDpzZWNyZXQw' \
  -H 'content-type: multipart/form-data;' \
  -F grant_type=refresh_token \
  -F scope=some_scope \
  -F refresh_token=da55eb5c-6d31-4d70-9af8-bad8ce8a777f

5）得到答案：

{"error":"server_error","error_description":"UserDetailsService is required."}

使用错误说明可以轻松地found on GitHub

找到合适的解决方案和解释

简单地说，有必要将UserDetailsS​​ervice注入AuthorizationServerConfiguration并将其添加到AuthorizationServerEndpointsConfigurer配置中。例如：

@Autowired
private AuthenticationManager authenticationManager;
@Autowired
private UserDetailsService userDetailsService;

@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints)
        throws Exception {
    endpoints
        .authenticationManager(authenticationManager)
        .userDetailsService(userDetailsService);

}

如果在此修改后发生以下错误

***************************
APPLICATION FAILED TO START
***************************

Description:

Field userDetailsService in demo.AuthserverApplication$AuthServerConfig required a bean of type 'org.springframework.security.core.userdetails.UserDetailsService' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.security.core.userdetails.UserDetailsService' in your configuration.

这意味着auth服务器代码缺少显式定义的UserDetailsS​​ervice（就像在问题中提到的原始教程一样）

出于测试目的，内存中的UserDetailsS​​ervice bean可以像这样指定

@EnableResourceServer
public class AuthserverApplication extends WebMvcConfigurerAdapter {

    @Bean
    public UserDetailsService userDetailsService() {
        InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();
        manager.createUser(User.withUsername("john").password("123").roles("USER").build());
        manager.createUser(User.withUsername("ivan").password("123").roles("USER").build());
        return manager;
    }

答案 1 :(得分：0)

OAuth服务器调用用户详细信息查询，因此需要为UserDetailsS​​ervice注入一个bean。在我的情况下，我能够通过LdapUserDetailsS​​ervice获得这个，因为我的用户详细信息保存在LDAP中。

答案 2 :(得分：0)

作为tut-spring-security-and-angular-js的示例，我还有3个应用 UI ， API 和 Auth 。我的 UI 应用程序有3种方案可以从我的 API 应用程序中获取数据。

  1. 来自我的 UI 应用程序本身（我必须从数据库加载一些设置和信息）
  2. 对于登录用户（我的 UI 应用程序显示与当前登录用户及其角色相关的一些内容）
  3. 用于客户端（某些页面使用JQuery加载数据ajax calls.eg：show表格格式为JQuery DataTable）

    4. 对于案例1：我使用spring-oauth2 密码流和管理员帐户。所以我创建了以

    的形式获取刷新令牌和访问令牌

}

    以下是从我的 API 服务器

    获取应用程序设置的示例代码 
    public List<Setting> loadApplicationSettings() {
    // @formatter:off
    SettingCriteria criteria = new SettingCriteria();
    criteria.setApplicationId(1234l);
    criteria.setStatus(Status.ACTIVE);

            "settings/search/list", 
            null, 
            criteria,HttpMethod.POST);
        // @formatter:on        
    return Arrays.asList(response.getBody().as(Setting[].class));
}

    对于案例2：我使用@EnableZuulProxy作为tut-spring-security-and-angular-js。

    注意：请勿将zuul映射设为公开映射。请参阅this answer。

    private static final Logger serviceLogger = LogManager.getLogger("serviceLogs." + OAuth2RestService.class.getName());

    @Autowired
    private OAuth2RestOperations restTemplate;

    public <T> T get(String url, Class<T> responseType, HttpHeader... headers) {
        return processRestService(url, HttpMethod.GET, null, responseType, headers);
    }

    public <T> T post(String url, Object body, Class<T> responseType, HttpHeader... headers) {
        return processRestService(url, HttpMethod.POST, body, responseType, headers);
    }

    public <T> T put(String url, Object body, Class<T> responseType, HttpHeader... headers) {
        return processRestService(url, HttpMethod.PUT, body, responseType, headers);
    }

    public <T> T delete(String url, Object body, Class<T> responseType, HttpHeader... headers) {
        return processRestService(url, HttpMethod.DELETE, body, responseType, headers);
    }

    private <T> T processRestService(String url, HttpMethod method, Object body, Class<T> responseType, HttpHeader... headers) {
        serviceLogger.info("Request URL [ " + url + " ] | Request Method [ " + method.name() + " ] | Expected Response-Type [ " + responseType + " ]");
        try {
            MultiValueMap<String, String> headerInfos = null;
            if (headers != null && headers.length > 0) {
                headerInfos = new LinkedMultiValueMap<String, String>();
                for (HttpHeader header : headers) {
                    headerInfos.add(header.getName(), header.getValue().toString());
                }
            }
            RequestEntity<Object> requestEntity = new RequestEntity<Object>(body, headerInfos, method, new URI(RestServiceConfig.createURL(url)));
            ResponseEntity<T> response = restTemplate.exchange(requestEntity, responseType);
            if (response.getStatusCode() == HttpStatus.OK) {
                return response.getBody();
            }
        }
        catch (URISyntaxException e) {
            e.printStackTrace();
        }
        return null;
    }
}

    我们必须将OAuth2RestOperations配置为自己。

    @Configuration
public class AppConfig {

    @Bean
    public RequestContextListener requestContextListener() {
        return new RequestContextListener();
    }

    @Bean
    @Scope(value = "session", proxyMode = ScopedProxyMode.INTERFACES)
    public OAuth2RestOperations oAuth2RestOperations(OAuth2ProtectedResourceDetails details, OAuth2ClientContext oauth2ClientContext) {
        OAuth2RestTemplate oAuth2RestTemplate = new OAuth2RestTemplate(details, oauth2ClientContext);
        return oAuth2RestTemplate;
    }

}

    HttpHeader类

    public class HttpHeader {
    private String name;
    private Object value;

    public HttpHeader(String name, Object value) {
        this.name = name;
        this.value = value;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Object getValue() {
        return value;
    }

    public void setValue(Object value) {
        this.value = value;
    }

}

    以下是使用Oauth2RestService类

    的示例代码 
    @Controller
@RequestMapping("/company")
public class CompanyController extends BaseController {

    @Autowired
    private OAuth2RestService restService;

    @GetMapping
    public String company(Model model) {
        CompanyCriteria criteria = new CompanyCriteria();
        criteria.setWithStaticContent(true);
        criteria.setWithSubKey(true);
        List<CompanyBean> companies = Arrays.asList(restService.post("company/search/list", criteria, CompanyBean[].class));
        model.addAttribute("companies", companies);
        return "home_page";
    }

}

    另一个api电话

    .....
UserCriteria criteria = new UserCriteria();
criteria.setEmail(email);
HashMap<String, Object> myHeaders = new HashMap<>();
myHeaders.put("key", "value");
restService.put("user/search", criteria, Long.class, new HttpHeader("someHeaders", myHeaders));

    如果不是为了获取单个用户并发的访问令牌，那么Everythings工作正常。

    例如，在执行客户端请求之前，我为每个请求提供了一些过滤器，这些请求是从我的 API 服务器获取一些数据。但是我从客户端获得了JQuery ajax调用方法，这些方法是异步运行的。在这种情况下，我的过滤器也会运行异步，当我的密码流的管理员帐户的访问令牌已过期时，这会出错。 见线程Concurrency problems refreshing OAuth2 tokens。所以我在现有过期时获取新访问令牌的方法中添加了synchronized。

    我希望对你有所帮助。如果您从我的代码中发现了一些弱点或代码，请不要费心去纠正我。
