Websocket http握手 cookie信息

// 连接服务端
String uri = "ws://localhost:8080/websocket";
System.out.println("Connecting to " + uri);
try {WebSocketContainer container = ContainerProvider.getWebSocketContainer();container.connectToServer(ClientSocket.class, URI.create(uri));
} catch (Exception e) {e.printStackTrace();
}// 客户端接收类
@ClientEndpoint
public class ClientSocket {@OnOpenpublic void onOpen(Session session) { }@OnMessagepublic void onMessage(String message) {}@OnErrorpublic void onError(Throwable t) {}
}

ClientSocket 可能需要继承 Endpoint，具体要看使用版本的情况

• webSocket 发送消息

session.getBasicRemote().sendText(message);

• webSocket 连接时 传递cookie 和header

public static Session connection(String uri, String cookieValue){Session session = null;try {WebSocketContainer container = ContainerProvider.getWebSocketContainer();ClientEndpointConfig cec = ClientEndpointConfig.Builder.create().configurator(new ClientEndpointConfig.Configurator() {public void beforeRequest(Map<String, List<String>> headers) {System.out.println("Setting user cookie in beforeRequest ...");if(null != cookieValue && !cookieValue.isEmpty()){ArrayList<String> value = new ArrayList<>();value.add(cookieValue);// 设置header，headers.put("cookie", value);}}}).build();session = container.connectToServer(ClientSocket.class, cec, URI.create(uri));} catch (Exception e) {e.printStackTrace();}return session;
}
