Spring Oauth2 Client,自动刷新过期的access_token
Posted
技术标签:
【中文标题】Spring Oauth2 Client,自动刷新过期的access_token【英文标题】:Spring Oauth2 Client, automatically refresh expired access_token 【发布时间】:2020-03-27 09:00:24 【问题描述】:让我解释一下我的用例。
我需要一个 spring boot oauth2 客户端应用程序(不是资源服务器,因为我们已经有一个单独的资源服务器)。我还有以下要求:
对于每个向资源服务器发出的请求,我们需要发送 id_token。 (通过自定义 resttemplate 来完成)。
对于任何请求,无论它是否调用资源服务器,如果访问令牌已过期,我的应用程序必须自动刷新它(无需任何用户干预,如任何弹出窗口或重定向。) .
如果 refresh_token 也已过期,则必须注销用户。
问题:
对于第 2 点和第 3 点,我花了很多时间阅读文档和代码以及 Stack Overflow,但无法找到解决方案(或不明白)。所以我决定将我在许多博客和文档中找到的所有部分放在一起,并提出我的解决方案。以下是我对第 2 点的解决方案。
我们可以看看下面的代码并建议这种方法是否有任何问题?

如何解决第 3 点我正在考虑扩展第 2 点的解决方案,但不确定我需要编写什么代码,谁能指导我?

【问题讨论】:
【参考方案1】:没有足够的细节来完全理解您的用例。很好理解:
Spring 安全性正在围绕 OAuth2 快速发展,请考虑提及您正在使用的版本。我的回答假设 5.2+ 您是在 servlet(用户以某种方式登录)还是非 servlet(如@Scheduled
方法)环境中
根据有限的信息和我有限的知识,我有以下提示:
考虑使用WebClient
而不是RestTemplate
,这是他们未来的发展方向。它是反应性的,但不要害怕。它也可以在“阻塞”环境中使用,您不会充分发挥它的潜力,但您仍然可以从它对 OAuth2 的更好支持中受益
WebClient
本身有一个 ServletOAuth2AuthorizedClientExchangeFilterFunction
,它几乎可以实现您想要实现的目标
在创建ServletOAuth2AuthorizedClientExchangeFilterFunction
时,您传入AuthorizedClientServiceOAuth2AuthorizedClientManager
,这是关于如何(重新)验证客户端的策略。
示例配置可能如下所示:
@Bean
public WebClient webClient(ClientRegistrationRepository clientRegistrationRepository, OAuth2AuthorizedClientService authorizedClientService)
AuthorizedClientServiceOAuth2AuthorizedClientManager manager = new AuthorizedClientServiceOAuth2AuthorizedClientManager(clientRegistrationRepository, authorizedClientService);
manager.setAuthorizedClientProvider(new DelegatingOAuth2AuthorizedClientProvider(
new RefreshTokenOAuth2AuthorizedClientProvider(),
new ClientCredentialsOAuth2AuthorizedClientProvider()));
ServletOAuth2AuthorizedClientExchangeFilterFunction oauth2 = new ServletOAuth2AuthorizedClientExchangeFilterFunction(manager);
oauth2.setDefaultClientRegistrationId("your-client-registratioin-id");
return WebClient.builder()
.filter(oauth2)
.apply(oauth2.oauth2Configuration())
.build();
并将其用作:
@Autowire
private final WebClient webClient;
...
webClient.get()
.uri("http://localhost:8081/api/message")
.retrieve()
.bodyToMono(String.class)
.map(string -> "Retrieved using password grant: " + string)
.subscribe(log::info);
希望这有助于朝着正确的方向前进!玩得开心
【讨论】:
您好,感谢您的时间和网络客户端信息。我将用它替换我的休息模板。虽然我不清楚一件事。正如我所提到的,并非所有请求都使用 webclient。假设用户想从使用 jdbc/jpa 直接连接到我的应用程序的数据库中查看一些信息。这种情况下如何刷新令牌? 我忘了说我使用的是 spring security 5.2,而且我有 web 应用程序,所以是的,我有 servlet 环境。以上是关于Spring Oauth2 Client,自动刷新过期的access_token的主要内容,如果未能解决你的问题,请参考以下文章
