同时发布到节点从服务器无响应 [英] No response from server while publishing to node

问题描述

我想获得该节点（在Android中使用 asmack 库），并试图在发布该节点的一些内容，但遗憾的是
当节点=（叶节点）mgr.getNode（nodeNameTxt.getText（）的toString（））;
行被执行我收到以下错误

I am trying to get the node (in android and using asmack library ) and trying to publish some content over that node , but unfortunately when node = (LeafNode) mgr.getNode(nodeNameTxt.getText().toString()); line gets executed i am getting following error

 No response from server.: 
at org.jivesoftware.smackx.pubsub.packet.SyncPacketSend.getReply(SyncPacketSend.java:50)
at org.jivesoftware.smackx.pubsub.packet.SyncPacketSend.getReply(SyncPacketSend.java:61)
at org.jivesoftware.smackx.pubsub.PubSubManager.getNode(PubSubManager.java:161)
at com.bcl.NodeManager.publishNode(NodeManager.java:176)
at com.bcl.NodeManager.access$1(NodeManager.java:167)
at com.bcl.NodeManager$2.run(NodeManager.java:101)
at java.lang.Thread.run(Thread.java:1019)

下面是我的code

    PubSubManager mgr = new PubSubManager(xmpp, "pubusb.example.com");
          // Get the node
    LeafNode node;

    try {
            //HERE I AM GETTING THE ERROR
        node = (LeafNode) mgr.getNode(nodeNameTxt.getText().toString());
        node.send(new PayloadItem("test" + System.currentTimeMillis(), 
                   new SimplePayload("book", "pubsub:test:book", "")));
    } catch (XMPPException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
    }

即使在以下行得到执行我得到了同样的错误。

even when a following line get executed i am getting the same error

createLeaf = mgr.createNode(nodeNameTxt.getText().toString());

我真的不知道发生了什么，因为我已设置 SmackConfiguration.setPacketReplyTimeout（10000）;
和服务器运行良好与stophe的JavaScript样本也。

I really dont know whats happening as i have set SmackConfiguration.setPacketReplyTimeout(10000); and server is running fine with stophe javascript sample also.

推荐答案

我怀疑到地址不正确，并在服务器的数据包不会被发送到发布订阅服务。尝试初始化您的pubsub经理这样。

I suspect that the "to" address is incorrect and the packet is not being sent to the pubsub service in your server. Try initializing your pubsub manager like this.

PubSubManager mgr = new PubSubManager(xmpp, "pubsub.xmppdomain.com");

其中xmppdomain.com当然是你的实际的XMPP域。

where xmppdomain.com is of course your actual xmpp domain.

您可以用smack.debugEnabled上运行（或任何Android的当量）检查XML的形式发送，确认这是要去的地方是应该的。

You can run with smack.debugEnabled on (or whatever the android equivalent is) to check the XML being sent, to confirm it is going where it should be.
