Okhttp websocket发送消息以打开套接字

现在,我有以下使用OkHttp与WebSockets配合使用的类,但其设置方式是我无法保持WebSocket处于打开状态,因此可以向Web套接字发送新消息。如何在不创建新的websocket连接的情况下继续向同一打开的websocket发送消息?

public class OkHttp extends WebSocketListener {
    public void run() {
        String hostname = "127.0.0.1";
        int port = 8888;
        Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(hostname, port));

        OkHttpClient client = new OkHttpClient.Builder().proxy(proxy).readTimeout(10, TimeUnit.SECONDS).build();

        Request request = new Request.Builder().url("ws://echo.websocket.org").build();
        client.newWebSocket(request, this);

        // Trigger shutdown of the dispatcher's executor so this process can exit
        // cleanly.
        client.dispatcher().executorService().shutdown();
    }

    @Override
    public void onOpen(WebSocket webSocket, Response response) {
        webSocket.send("Hello...");
        webSocket.send("...World!");
        webSocket.send(ByteString.decodeHex("deadbeef"));
        webSocket.close(1000, "Goodbye, World!");
    }

    @Override
    public void onMessage(WebSocket webSocket, String text) {
        System.out.println("MESSAGE: " + text);
    }

    @Override
    public void onMessage(WebSocket webSocket, ByteString bytes) {
        System.out.println("MESSAGE: " + bytes.hex());
    }

    @Override
    public void onClosing(WebSocket webSocket, int code, String reason) {
        webSocket.close(1000, null);
        System.out.println("CLOSE: " + code + " " + reason);
    }

    @Override
    public void onFailure(WebSocket webSocket, Throwable t, Response response) {
        t.printStackTrace();
    }
}

newWebSocket()方法返回一个WebSocket,您可以使用它来排队出站邮件。
