单点登录实现

前端代码：

function openIsc(){
    $.get("${ctx}/singleSignOn/getUrltoisc", function(msg) {
        try {
            if(!msg){
                 Dialog.error("无法跳转");
               }
           else{
                var url = msg;
                window.open(url,'_blank','noopener noreferrer');
           }
        } catch (e) {
            console.log(e);
            Dialog.error("无法跳转");
        }
    });

通过ajax访问后台，后台取出链接通过Window.open打开。

后台代码：

public class SingleSignOnService {
    private  final String host = "172.18.247.XXX"; // artemis网关服务器ip端口;
    private  final String appKey = "*******";  // 秘钥appkey
    private  final String appSecret = "XXXXXXXXXX";// 秘钥appSecret
    private  final String sevice = "ip";//海康威视安防监控平台网址
    private  final String urlHead = "ip/bic/ssoService/v1/tokenLogin?"; // 拼接URL字符串开头;
    private  String getIscToken(String useAccount) throws ServiceException {
        /**
         * STEP1：设置平台参数，根据实际情况,设置host appkey appsecret 三个参数.
         */
        ArtemisConfig.host = host; // artemis网关服务器ip端口
        ArtemisConfig.appKey = appKey;  // 秘钥appkey
        ArtemisConfig.appSecret = appSecret;// 秘钥appSecret
        /**
         * STEP2：设置OpenAPI接口的上下文
         */
        final String ARTEMIS_PATH = "/artemis";
        /**
         * STEP3：设置接口的URI地址
         */
        String getTokenUrl = ARTEMIS_PATH+"/api/cas/v1/tgt/login";
        Map<String, String> path = new HashMap<String, String>(2) {
            {
                put("https://", getTokenUrl); //根据现场环境部署确认是http还是https
            }
        };

        /**
         * STEP4：设置参数提交方式
         */
        String contentType = "application/json";

        /**
         * STEP5：组装请求参数
         */
        Map<String, String> body = new HashMap<String, String>();
        body.put("userCode", useAccount);
        body.put("service",sevice );
        body.put("language", "zh_CN");
        /**
         * STEP6：调用接口
         */
        String result = ArtemisHttpUtil.doGetArtemis(path, body, null, contentType, null);// get请求application/json类型参数
        JSONObject resData = JSONObject.parseObject(result);
        ServiceAssert.hasText(resData.toString(), "调用接口失败");
        ServiceAssert.isTrue(resData.containsKey("code"), "获取token失败");
        String dataString = resData.getString("data");
        JSONObject tokenData = JSONObject.parseObject(dataString);
        String token = tokenData.getString("token");
        return token;
    }

    public String getIscIndexURL(String useAccount) throws ServiceException {
