我正在使用SpringBoot尝试通过websocket连接到janus。我收到一个http请求，然后将命令发送给janus。
我在自己的机器上使用janus on docker，在执行第一个请求后，尝试升级连接（http>ws）时出现异常。
java.util.concurrent.executionexception:javax.websocket.deploymentexception:初始化到[ws://172.17.0.2:8188/janus]的websocket连接的http请求失败，原因是：javax.websocket.deploymentexception:初始化到[ws://172.17.0.2:8188/janus]的websocket连接的http请求失败
原因：java.io.eofexception:到websocket的http升级失败，但可能已收到部分数据：状态代码[0]，http头[{}]
这是我的websocketconfiguration类：

@EnableWebSocket
@Configuration
public class WebSocketConfiguration implements WebSocketConfigurer {

    private final MessageDelegator handler;
    private final Logger logger = LoggerFactory.getLogger(this.getClass().getName());

    @Autowired
    public WebSocketConfiguration(MessageDelegator handler) {
        this.handler = handler;
    }

    @Override
    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
        RequestUpgradeStrategy upgradeStrategy = new TomcatRequestUpgradeStrategy();
        registry.addHandler(handler, "/player")
                .setAllowedOrigins("*")
                .addInterceptors(new HandshakeConfiguration())
                .setHandshakeHandler(new DefaultHandshakeHandler(upgradeStrategy));

        logger.info("WebSocket endpoint: :8666/player");
    }
}

握手配置是一个拦截器：

public class HandshakeConfiguration implements HandshakeInterceptor {

    private Logger logger = LoggerFactory.getLogger(this.getClass().getName());

    @Override
    public boolean beforeHandshake(ServerHttpRequest request, ServerHttpResponse response, WebSocketHandler wsHandler, Map<String, Object> attributes) throws Exception {
        logger.info(request.getHeaders().toString());
        request.getHeaders().add("sec-websocket-Protocol", "janus-protocol");
        logger.info(request.getHeaders().toString());

        return true;
    }

    @Override
    public void afterHandshake(ServerHttpRequest request, ServerHttpResponse response, WebSocketHandler wsHandler, Exception exception) {
        logger.info(response.getHeaders().toString());
    }
}

握手前：
m、 f.w.j.e.w.c.握手配置：[主机：”localhost:8666，upgrade:“websocket”，connection:“upgrade”，sec websocket key:“ynzls1po5dl3awtf/jpd1g==”，sec websocket version:“13”，sec websocket extensions:“permessage deflate；客户端\u最大\u窗口\u位”，用户代理：“python/3.6 websockets/8.1”]
正在添加websocket子策略：
m、 f.w.j.e.w.c.握手配置：[主机：”localhost:8666，upgrade:“websocket”，connection:“upgrade”，sec websocket key:“ynzls1po5dl3awtf/jpd1g==”，sec websocket version:“13”，sec websocket extensions:“permessage deflate；客户端\u最大\u窗口\u位”，用户代理：“python/3.6 websockets/8.1”，sec websocket协议：“janus协议”]
握手后：m.f.w.j.e.w.c.握手配置：[]
