Question

嗨有没有办法做android xmpp客户端，它将能够获得消息接收确认（XEP-0184）我读到在smack中有XEP-0184但是正常的smack不能用于android（或者我可以' t do）总是有SASL身份验证例外。

Answer 1

Smack通过SMACK-331获得了对XEP-0184的支持。你不能使用Smack＆lt; 4.1直接在Android下，你需要Smack 4.1（或更高版本）。

您可以在DeliveryReceiptManager的javadoc中阅读有关Smack的XEP-0184 API的更多信息。

Answer 2

是的，这适用于普通的Smack。

Gradle依赖

compile "org.igniterealtime.smack:smack-android:4.1.0"
compile "org.igniterealtime.smack:smack-tcp:4.1.0"
compile "org.igniterealtime.smack:smack-extensions:4.1.0" // <-- XEP-0184 classes

准备XMPPTCPConnection，即在连接（）之前连接处理程序以获取送达回执

DeliveryReceiptManager.getInstanceFor(mConnection).addReceiptReceivedListener(new ReceiptReceivedListener() {
        @Override
        public void onReceiptReceived(String fromJid, String toJid, String deliveryReceiptId, Stanza stanza) {
            Log.d(TAG, "onReceiptReceived: from: " + fromJid + " to: " + toJid + " deliveryReceiptId: " + deliveryReceiptId + " stanza: " + stanza);
        }
    });

发送邮件时，请确保包含MessageReceiptRequest

Chat chat;
if (StringUtils.isNullOrEmpty(threadId)) {
    chat = getChatManager().createChat(to);
    Log.d(TAG, "sendMessage: no thread id so created Chat with id: " + chat.getThreadID());
} else {
    chat = getChatManager().getThreadChat(threadId);
    Log.d(TAG, "sendMessage: thread id was used to continue this chat");
}
Message message = new Message(to);
message.addBody("EN", messageText);
String deliveryReceiptId = DeliveryReceiptRequest.addTo(message);
chat.sendMessage(message);
Log.d(TAG, "sendMessage: deliveryReceiptId for this message is: " + deliveryReceiptId);

全部完成

现在，您可以判断对方是否收到了已发送的消息，因为上面的Chat.sendMessage（消息）代码中获取的deliveryReceiptId将由之前设置的onReceiptReceived回调记录。

如何在Smack中使用XMPP XEP-0184“消息发送收据”？
