cas restful接口实现SSO

一、使用pac4j插件

https://apereo.github.io/cas/6.0.x/protocol/REST-Protocol.html 官网链接cas restclient

二、cas server端下载依赖

三、使用客户端测试连接

    private final static String CAS_LOGIN_URL = "https://mmoayyed.unicon.net:8433/cas";
//    private final static String CAS_LOGIN_URL = "https://mmoayyed.unicon.net:8433/cas/v1/tickets/login";
    private final static String APP_URL = "http://app1.cas.com:9001/hello/index";
    private final static String serviceUrl = "http://app1.cas.com:9001";


    @PostMapping(value="/hello/restLogin")
    public void restLogin(HttpServletRequest request, HttpServletResponse response) {
        final CasConfiguration casConfiguration = new CasConfiguration(CAS_LOGIN_URL);
        casConfiguration.setRestUrl("https://mmoayyed.unicon.net:8433/cas/v1/tickets/login");
        CasRestFormClient client = new CasRestFormClient();
        client.setConfiguration(casConfiguration);

        System.out.println("界面提交执行");

        WebContext webContext = new J2EContext(request, response);

        try {
            UsernamePasswordCredentials credentials = client.getCredentials(webContext);
            String userName = credentials.getUsername();
            System.out.println(userName);
            CasRestProfile profile = client.getUserProfile(credentials, webContext);
            String tgc = profile.getTicketGrantingTicketId();
            String redirectUrl=CAS_LOGIN_URL+"?service="+APP_URL+"&tgc="+tgc;
            final TokenCredentials casCredentials = client.requestServiceTicket(serviceUrl, profile, webContext);
            // validate service ticket
            final CasProfile casProfile = client.validateServiceTicket(serviceUrl, casCredentials, webContext);
            response.sendRedirect("http://app1.cas.com:9001/hello/restLogin");
        } catch (HttpAction | IOException e) {
//        } catch (HttpAction e) {
            e.printStackTrace();
        }
    }

 这时：出现的问题是使用cas restclient进行测试，虽然显示时st认证成功，但是在cas server的登陆页依旧没有显示成功，而没有使用cas restclient接口的时候，cas client在st认证成功的情况下，cas server的登陆页显示的就是登陆成功的界面

对此分析借鉴的原因是：要是由于业务系统使用自己的登陆页面登陆后，没有在CAS的域下写入TGC的Cookie值
