TooTallNate java-websockets：无法连接到WSS服务器

Question

我正在尝试使用TooTallNate-Jave-Websocket libray连接到WSS套接字。

每当我开始连接时，都会出现此错误：

SocketClient : onClose
 Invalid status code received: 421 Status line: HTTP/1.1 421 unknown protocol
 1002
 false

我正在以这种方式形成网址

  Uri.Builder builder = new Uri.Builder();
                builder.scheme("wss")
                        .authority(server)
                        .appendQueryParameter("session-id", sessionId)
                        .appendQueryParameter("udid", udid)
                        .appendQueryParameter("token", token);

    logger.info(" The server URL "+ builder.build().toString() + " "+ builder.build().getScheme() + " "+ builder.build().getAuthority()); 

SocketClient socks = new SocketClient(new URI(builder.build().toString())); 
socks.connect();

我的websocket实现非常基础，就像这样：

public static class SocketClient extends WebSocketClient{

        public SocketClient(URI serverUri, Draft draft){
            super(serverUri, draft);
        }

        public SocketClient(URI serverUri){
            super(serverUri);
        }

        @Override
        public void onMessage(String message) {
            logger.info("SocketClient : OnMessage");
            logger.info(message);
        }

        @Override
        public void onOpen(ServerHandshake handshakedata) {
            logger.info("SocketClient : onOpen");
            logger.info(handshakedata.getHttpStatus() + "");
        }

        @Override
        public void onClose(int code, String reason, boolean remote) {
            logger.info("SocketClient : onClose");
            logger.info(reason);
            logger.info(code + "");
            logger.info( remote + "");
        }

        @Override
        public void onError(Exception ex) {
            logger.info("SocketClient : onError");
            logger.info(ex.toString());
        }
    }

我检查了我要连接的服务器是否具有有效的证书，并且它确实有效。所以我猜我构造URL的方式出了问题。
