第三方登录单点

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.doDelete(url, null);

删除CASTGC的cookie

//刪除cookie
Cookie newCookie = new Cookie("CASTGC", null);

newCookie.setMaxAge(0);
newCookie.setPath("http://127.0.0.1:8080/");
response.addCookie(newCookie);
