1、拿到ticket
2、解析

public String login(String ticket, String redirectUri) {
        // 组装GET请求的参数
        Map<String, Object> param = new HashMap<>(2);
        param.put("ticket", ticket);
        param.put("service", redirectPrefix + "?redirectUri=sdnu-consume-bill-web");
        String result = HttpUtil.get(getUserInfoPrefix, param, 2000);
        System.out.println(result);
        Document xml = XmlUtil.parseXml(result);

        String userNo = null;
        String userName = null;
        String unitNo = null;

        try {
            userNo = xml.getElementsByTagName("cas:user").item(0).getTextContent();
            userName = xml.getElementsByTagName("cas:cn").item(0).getTextContent();
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }

        //生成老版token
        Map<String, Object> cookieMap = new HashMap<>(4);
        cookieMap.put(JwtUtil.KEY_USER_NO, userNo);
        cookieMap.put(JwtUtil.KEY_USER_NAME, userName);
        // TODO 去表里查
        cookieMap.put(JwtUtil.KEY_UNIT_NO, unitNo);
        String token = JwtUtil.generateToken(cookieMap);
        //生成zbpToken
        JwtUserInfo userInfo = new JwtUserInfo();
        userInfo.setUserId(userNo);
        userInfo.setName(userName);
        userInfo.setUnitNo(unitNo);
        userInfo.setTokenType(JwtUserInfo.TokenType.ADMIN);
        AuthorInfo authorInfo = tokenUtil.createAuthInfo(userInfo, null);
        String zbpToken = authorInfo.getToken();

        return String.format("<!DOCTYPE html>\n" +
