shiro buji pac4j cas 单点退出不起作用

Question

spring 启动 2.2.5

shiro-spring-boot-web-starter 1.5.1

布吉-pac4j 4.1.1

pac4j-cas 3.8.3

cas 覆盖模板 5.3.

我在 tomcat 中使用 https 启动 cas 服务器，并在 eclipse 中启动两个客户端（pac4j1 和 pac4j2）。

单点登录有效，但 single sign out 失败。

以下是我的配置：

我只在 cas 服务器下添加了一个 service 文件，如下所示：

{
  "@class": "org.apereo.cas.services.RegexRegisteredService",
  "serviceId": "^(http)://localhost.*",
  "name": "local",
  "id": 10000003, 
  "evaluationOrder": 1
}

application.yml 共 pac4j1:

server:
  port: 8444
  servlet:
    context-path: /pac4j1

cas:
  client-name: pac4j1Client
  server:
    url: https://localhost:8443/cas
  project:
    url: http://localhost:8444/pac4j1

Pac4jConfig:

@Configuration
public class Pac4jConfig {

    @Value("${cas.server.url}")
    private String casServerUrl;

    @Value("${cas.project.url}")
    private String projectUrl;

    @Value("${cas.client-name}")
    private String clientName;

    @Bean("authcConfig")
    public Config config(CasClient casClient, ShiroSessionStore shiroSessionStore) {

        Config config = new Config(casClient);
        config.setSessionStore(shiroSessionStore);
        return config;
    }


    @Bean
    public ShiroSessionStore shiroSessionStore(){
        return new ShiroSessionStore();
    }


    @Bean
    public CasClient casClient(CasConfiguration casConfig){

        CasClient casClient = new CasClient(casConfig);

        casClient.setCallbackUrl(projectUrl + "/callback?client_name=" + clientName);
        casClient.setName(clientName);
        return casClient;
    }

    @Bean
    public CasConfiguration casConfig(){
        final CasConfiguration configuration = new CasConfiguration();

        configuration.setLoginUrl(casServerUrl + "/login");

        configuration.setProtocol(CasProtocol.CAS20);
        configuration.setAcceptAnyProxy(true);
        configuration.setPrefixUrl(casServerUrl + "/");        

        return configuration;
    }

}

shiro 配置：

        manager.setSubjectFactory(subjectFactory);

        return manager;
    }    

    @Bean

        return realm;

        SingleSignOutFilter singleSignOutFilter = new SingleSignOutFilter();
        singleSignOutFilter.setCasServerUrlPrefix(casServerUrl);
        singleSignOutFilter.setIgnoreInitConfiguration(true);

        bean.setFilter(singleSignOutFilter);
        bean.addUrlPatterns("/*");
        bean.setEnabled(true);

        shiroFilterFactoryBean.setFilters(filters);
        return shiroFilterFactoryBean;
    }   

}

cas server的

application.properties是默认的，cas server使用https(https://localhost:8443/cas)而cas clients是http(http://localhost:8444/pac4j1)。

我哪里错了？

Answer 1

在 leopal 提供的 link SLO 的帮助下，我知道 cas 服务器需要将注销请求发送回客户端。

因此，我查看了cas服务器的日志，发现INFO [org.apereo.cas.logout.DefaultLogoutManager] - <Performing logout operations for。

所以我为 org.apereo.cas.logout 添加了日志，发现关于注销有一些类：DefaultLogoutManager、DefaultSingleLogoutServiceLogoutUrlBuilder、DefaultSingleLogoutServiceMessageHandler 和 SimpleUrlValidator.

执行注销时，DefaultSingleLogoutServiceLogoutUrlBuilder.determineLogoutUrl将从注册服务中获取注销url，或者如果原始url是有效的[=，则从cas客户端获取原始url 46=].

所以我的问题是：我没有在服务json文件和来自cas客户端的原始url中定义注销url localhost:8444 这是一个无效的 ipv4。因此，cas 服务器将不会向客户端发送注销请求。

解决方案是：在项目url中使用ip，而不是在cas客户端的application.yml中使用localhost：

cas:
  client-name: pac4j1Client
  server:
    url: https://localhost:8443/cas
  project:
    url: http://192.168.2.119:8444/pac4j1

为每个 cas 客户端服务 json 文件（尚未尝试）设置了另一个解决方案 logoutUrl。
