第三方的单点登录和公司的单点登录集成时，需要从第三方登录公司的单点系统，
以下为功能单点登录系统提供的后台restful API，返回json格式的数据接口
1． 登录
验证用户名密码,返回TGT
1.1、post请求 x-www-form-urlencoded 编码方式
url：http://xxxx/cas/v2/tickets
params：username=admin&password=bonc
例：（仅作参考）
RestTemplate restTemplate=new RestTemplate();
User user=new User("admin","bonc");
//提交的body内容为user对象，请求的返回的body类型为String
ResponseEntity<String> responseEntity=restTemplate.postForEntity("http://127.0.0.1:8080/cas/v2/tickets",user,String.class);
验证通过返回结果如下：
{"status": "true","TGT":"TGT-2-DgHeQe3cfXXaHGdlO91MgQr05ItWSyJpHFzrQvX0ayvNlXcrhc-cas"}
验证失败：
{"status": "false","message":"error.authentication.credentials.bad"}
1.2、将获取到的TGT的值放到和cas同域的/ path下，key名为CASTGC
例子：
String TGT = jsonV2.getString("TGT");
Cookie cookie = new Cookie("CASTGC", TGT);
cookie.setPath("/");
response.addCookie(cookie);
这就完成了cas服务端登录
然后跳转到公司门户，可以直接访问
（注：一定要保证登录程序和cas的同域，部署不满足时，可以用反向代理来保证同域）
2、退出
从cookie中取key为CASTGC的cookie值:cookies[i].getName().equals("CASTGC")
delete请求： http:// xxxx /cas/v1/tickets/CASTGC的值
String url = "http://127.0.0.1:8080" + "/cas/v1/tickets/" + CASTGC;WebClientUtil.java
WebClientUtil.doDelete(url, null);
