在我的websocket服务器中,我正在检索一个cutom标题,我不想链接到它来自的会话。我已经找到了一个有效的ServerEndpointConfig.Configurator
:
public class WebSocketConfig extends ServerEndpointConfig.Configurator {
private static final Logger LOG = LoggerFactory.getLogger(WebSocketConfig.class);
@Override
public void modifyHandshake(ServerEndpointConfig sec, HandshakeRequest request, HandshakeResponse response) {
Map<String, List<String>> headers = request.getHeaders();
if (headers != null) {
if (headers.containsKey("key")) {
List<String> header = headers.get("key");
if (header.size() > 0) {
LOG.info(header.get(0));
}
}
}
}
}
我的ServerEndpoint
看起来像这样:
@ServerEndpoint(value = "/websocket", configurator = WebSocketConfig.class)
public class WebSocket {
private static final Logger LOG = LoggerFactory.getLogger(WebSocket.class);
public WebSocket() {
}
@OnOpen
public void onOpen(Session session) {
LOG.info("OnOpen");
}
@OnClose
public void onClose(Session session) {
LOG.info("OnClose");
}
@OnMessage
public void onMessage(String message, Session session){
LOG.info("OnMessage: " + message);
}
}
在函数onOpen
中,我想保存将会话链接到标头值。但是我怎样才能访问它?
问候。
答案 0 :(得分:0)
我找到了解决问题的方法,我必须在路径中添加路径参数。
不确定这是否是最佳解决方案。
@ServerEndpoint(value = "/websocket/{key}", configurator = WebSocketConfig.class)
public class WebSocket {
private static final Logger LOG = LoggerFactory.getLogger(WebSocket.class);
public WebSocket() {
}
@OnOpen
public void onOpen(Session session, @PathParam("key") String key) {
LOG.info("OnOpen");
}
@OnClose
public void onClose(Session session) {
LOG.info("OnClose");
}
@OnMessage
public void onMessage(String message, Session session){
LOG.info("OnMessage: " + message);
}
}
