ssl - 尝试将 websocket 连接到安全的客户端端点会引发错误 : XNIO000100: 'https' URL scheme chosen but no SSL provider given

Question

我正在尝试在 java 中创建一个 websocket，它监听端点 f.ex 上的本地应用程序。 “wss://localhost.localapp.com:8080/”。

应用程序确实通过该 websocket 发送有关正在发生的事情的信息。

当我运行 web 应用程序并尝试连接到安全的 websocket 时，它会抛出此错误:

XNIO000100: 'https' URL scheme chosen but no SSL provider given

这是我连接到客户端端点的代码:

@ClientEndpoint
public class ClientEndpoint {

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

    public ClientEndpoint() {
        WebSocketContainer container = ContainerProvider.getWebSocketContainer();
        try {
            container.connectToServer(this, new URI("wss://localhost.localapp.com:8080/"));
        } catch (DeploymentException | URISyntaxException | InterruptedException | IOException e) {
            System.out.println("Connection error occured!: " + e);
        }
    }

    @OnOpen
    public void onOpen(Session session) {
        this.logger.info("New websocket session opened: " + session.getId());
    }

    @OnClose
    public void onClose(Session session) {
        this.logger.info("Websoket session closed: " + session.getId());
    }

    @OnMessage
    public void onMessage(Session session, String message) throws IOException, EncodeException {
        this.logger.info("Message recieved: " + message);
    }

    @OnError
    public void error(Session session, Throwable t) {
        t.printStackTrace();
    }
}

所以错误发生在这行代码上:

container.connectToServer(this, new URI("wss://localhost.localapp.com:8080/"));

堆栈跟踪输出如下:

ERROR localhost jboss7.1 [RunnerReadFacade] Application was stopped due to exception. Transaction is rollbacked.: java.lang.IllegalArgumentException: XNIO000100: 'https' URL scheme chosen but no SSL provider given

我该如何解决？

使用 JavaScript，我不需要 SSL 提供程序，只需运行即可简单地创建与 websocket 的连接:

websocket = new WebSocket("wss://localhost.localapp.com:8080/");

为什么只有Java会报错？

更新:

这可能无法完成，因为应用程序在您的本地计算机上，而服务器不在本地。

但是，如果您使用本地服务器，可以做到这一点吗？

您可以切换到程序化客户端端点或定义线程本地 SSL 上下文。查看详情 https://issues.jboss.org/browse/THORN-2131 (wsstest-master.zip 包括演示应用程序)。 “实现 io.undertow.websockets.jsr.WebsocketClientSslProvider 并添加 META-INF/services 条目”对我不起作用。
