Question

使用Eclipse IDE尝试为OpenHab项目创建Java Websocket客户端，从而使用默认的Jetty Websocket库。 OpenHab项目打算连接到需要令牌授权的websocket端点，发送请求消息并检索实时/连续测量。

所以，我有

public static final String SUBSCRIPTION_URL = "wss://api.tibber.com/v1-beta/gql/subscriptions";

此外，我的WS开放代码：

public void open() throws Exception {
    if (isConnected()) {
        logger.warn("Open: connection is already open");
    }
    logger.warn("Connecting to: {}", SUBSCRIPTION_URL);

    sslContextFactory = new SslContextFactory(true);
    sslContextFactory.setTrustAll(true);

    client = new WebSocketClient(sslContextFactory);
    client.setMaxIdleTimeout(360 * 1000);

    TibberWebSocketListener socket = new TibberWebSocketListener();

    request = new ClientUpgradeRequest();
    String token = new StringBuilder("Bearer ").append(configuration.getToken()).toString();
    request.setHeader("Authorization", token);
    request.setSubProtocols("graphql-subscriptions");

    client.start();
    client.connect(socket, new URI(SUBSCRIPTION_URL), request);

}

但是，使用此代码，看来我已经建立连接，但最终出现IOException：1分钟后管道破裂。如果我只连接无信息/连接有发送信息，我都会遇到相同的错误。

Answer 1

java.io.IOException：管道损坏

这意味着Java（和Jetty）下的操作系统或网络检测到连接已关闭。

“破损管道”实际上相当普遍，尤其是在移动设备或无线网络中。

Java或Jetty也无能为力，它发生在其控制范围之外。
