CAS应用集成
本文介绍CAS应用如何 与MaxKey进行集成。
应用注册
应用在MaxKey管理系统进行注册，注册的配置信息如下
CAS客户端配置
本文使用JAVA WEB程序为例

引入依赖包
jar包依赖如下
cas-client-core-3.2.1.jar
commons-codec-1.9.jar
commons-io-2.2.jar
commons-logging-1.1.1.jar

SpringBoot CAS配置
源代码地址
https://github.com/MaxKeyTop/MaxKey-SpringBoot4CAS-demo
demo分别写了三个请求:拦截请求 test1/index,test1/index1 以及不拦截请求test1/index2,
引入依赖包
<dependency>
<groupId>net.unicon.cas</groupId>
<artifactId>cas-client-autoconfig-support</artifactId>
<version>2.3.0-GA</version>
</dependency>
SpringBoot配置
server:
port: 8989
cas:
# cas服务端地址
server-url-prefix: http://sso.maxkey.top/sign/authz/cas/
# cas服务端登陆地址
server-login-url: http://sso.maxkey.top/sign/authz/cas/login
# 客户端访问地址
client-host-url: http://localhost:8989/
# 认证方式，默认cas
validation-type: cas
# 客户端需要拦截的URL地址
authentication-url-patterns:
- /test1/index
- /test1/index1
扩展配置项
cas.authentication-url-patterns
cas.validation-url-patterns
cas.request-wrapper-url-patterns
cas.assertion-thread-local-url-patterns
cas.gateway
cas.use-session
cas.redirect-after-validation
cas.allowed-proxy-chains
cas.proxy-callback-url
cas.proxy-receptor-url
cas.accept-any-proxy
server.context-parameters.renew
CAS注解
在application启动类上加上 @EnableCasClient 注解
@SpringBootApplication
@EnableCasClient
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
获取登录用户信息
@GetMapping("test1/index1")
public String index1(HttpServletRequest request){
String token =request.getParameter("token");
System.out.println("token : "+token);
Assertion assertion = (Assertion) request.getSession().getAttribute(AbstractCasFilter.CONST_CAS_ASSERTION);
String username= assertion.getPrincipal().getName();
System.out.println(username);
return "test index cas拦截正常,登录账号:"+username;
}
