java - android使用websocket无法访问cookie。

我的java服务端为了分清各个用户使用session里的用户名做了区分，html页面使用没有问题，但是在android端访问的时候取不到cookie值。

public boolean beforeHandshake(ServerHttpRequest request, ServerHttpResponse response, WebSocketHandler wsHandler,
            Map attributes) throws Exception {
        if (request instanceof ServletServerHttpRequest) {
            ServletServerHttpRequest servletRequest = (ServletServerHttpRequest) request;
            // 链接webSocket时传递的参数 标识是否是特定分组， Null表明不是
            //String type = (String) servletRequest.getServletRequest().getParameter("type");
            HttpSession session = servletRequest.getServletRequest().getSession(false);
            if (session != null) {
                LoginUserInfo user = (LoginUserInfo) session.getAttribute("loginUserInfo");
//                System.out.println("id");
//                System.out.println(session.getId());
                if (user != null) {
                    attributes.put("user", user);
                    //attributes.put("type", type);
                    
                    Enumeration params = servletRequest.getServletRequest().getParameterNames();
                    while (params.hasMoreElements()) {
                        String param = params.nextElement();
                        attributes.put(param, servletRequest.getServletRequest().getParameter(param));                        
                    }
                }
            }
        }
        return true;
    }

//websocket建立

WebSocketClient websocket;
