smack 消息发送状态

Question

我正在使用 smack 和 openfire 在 android 中创建聊天应用程序。 对于消息状态，我在其他中传递和显示的消息没有问题 客户（仔细检查）。 我将向发件人发送一个简单的 json 消息，如下所示： {“交付”：timestapmp} 并解析它并仔细检查低于之前发送的时间戳的消息。 问题是关于发送状态（一次检查）。 当我发送消息时，服务器没有响应该消息已发送的任何内容。 是否可以在 smack 中发送带有来自服务器的回调的消息。 如果可能，是否可以在回调响应中发送时间服务器。 谢谢。

Answer 1

据我所知，我已经掌握了这个接口：ReceiptReceivedListener，它位于smack 4.2

以下是我的实现方式：

private ReceiptReceivedListener receiptReceivedListener;

/**
 * get DeliveryReceiptManager
 *
 * @return
 */
private DeliveryReceiptManager getDeliveryReceiptManager() {
    if (deliveryReceiptManager == null && getConnection() != null) {
        deliveryReceiptManager = DeliveryReceiptManager.getInstanceFor(getConnection());
    }
    return deliveryReceiptManager;
}

添加监听器

getDeliveryReceiptManager().addReceiptReceivedListener(receiptReceivedListener);

收到回电

receiptReceivedListener = new ReceiptReceivedListener() {
    @Override
    public void onReceiptReceived(Jid fromJid, Jid toJid, String receiptId, Stanza receipt) {
        //TODO : on recieved status of message delivery
    }
};

这肯定会帮助你

以下是 Smack 4.2 的界面以及完整的详细信息：

/**
 * Callback invoked when a new receipt got received.
 * <p>
 * {@code receiptId} correspondents to the message ID, which can be obtained with
 * {@link org.jivesoftware.smack.packet.Stanza#getStanzaId()}.
 * </p>
 * 
 * @param fromJid the jid that send this receipt
 * @param toJid the jid which received this receipt
 * @param receiptId the message ID of the stanza(/packet) which has been received and this receipt is for
 * @param receipt the receipt
 */
void onReceiptReceived(Jid fromJid, Jid toJid, String receiptId, Stanza receipt);

Answer 2

private void acknowledgementFromServer(final Message message) throws StreamManagementException.StreamManagementNotEnabledException {
        if (connection != null && connection.isSmEnabled()) {
            connection.addStanzaIdAcknowledgedListener(message.getStanzaId(), new StanzaListener() {
                @Override
                public void processStanza(Stanza packet) throws SmackException.NotConnectedException, InterruptedException {

                        MessageAsyncTask task = new MessageAsyncTask(packet.getStanzaId(), MSG_STATUS_SENT);
                        task.execute();

                }
            });
        }

嘿，你可以这样做......每次发送消息时调用方法，方法是将消息作为参数传递给上述方法

注意：应该启用流管理才能使其工作，可以如下完成：

DeliveryReceiptManager.setDefaultAutoReceiptMode(DeliveryReceiptManager.AutoReceiptMode.always);
        ProviderManager.addExtensionProvider(DeliveryReceipt.ELEMENT, DeliveryReceipt.NAMESPACE, new DeliveryReceipt.Provider());
        ProviderManager.addExtensionProvider(DeliveryReceiptRequest.ELEMENT, DeliveryReceipt.NAMESPACE, new DeliveryReceiptRequest.Provider());
