Question

我在使用Java连接到websocket时遇到问题。我在以前在localhost端口8080上运行服务器端点时，我的代码工作正常，但是当我尝试连接到我在网上找到的websocket时，我正在

javax.websocket.DeploymentException：来自服务器的HTTP响应[HTTP / 1.1 200 OK]不允许HTTP升级到WebSocket

我使用Simple Websocket客户端chrome扩展测试了ws端点，我得到了响应。所以服务器肯定能正常工作。

我的客户代码：

    package clientendpoints;

import javax.websocket.ClientEndpoint;
import javax.websocket.CloseReason;
import javax.websocket.DeploymentException;
import javax.websocket.OnClose;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;

//import com.fasterxml.jackson.databind.ObjectMapper;
import java.io.IOException;
import java.net.URI;
import java.util.logging.Logger;

@ClientEndpoint
public class MyClientEndpoint {
    private Logger logger = Logger.getLogger(this.getClass().getName());
    Session session = null;
    public MyClientEndpoint(String endpointURI) {
        //start connection 
        javax.websocket.WebSocketContainer container = javax.websocket.ContainerProvider.getWebSocketContainer();
        try {
            container.connectToServer(this, new URI(endpointURI));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @OnOpen
    public void onOpen(Session session) {
        logger.info("Client onOpen..." + session.getId());
        this.session = session;    
    }

    @OnMessage
    public void onMessage(String message, Session session) {
        logger.info("MyClientEndpoint log: " + message);
    }

    @OnClose
    public void onClose(Session session, CloseReason closeReason) {
        logger.info(String.format("Session %s close because of %s", session.getId(), closeReason));
    }

我用

来称呼它

MyClientEndpoint client = new MyClientEndpoint(MY_SECRET_ENDPOINT);

无法连接到Java中的Web套接字
