Question

当使用Smack将数据包发送到openfire时，我得到错误remote-server-not-found（404）。任何人都可以解释这个错误意味着什么？它意味着无法连接到服务器或数据包有问题？

        PacketFilter responseFilter = new PacketIDFilter(packet.getPacketID());
        PacketCollector response = connection.createPacketCollector(responseFilter);

        connection.sendPacket(packet);



        // Wait up to a certain number of seconds for a reply.
        Packet result = response.nextResult(timeout);



        // Stop queuing results
        response.cancel();



        if (result == null) {
            throw new XMPPException("No response from server.");
        }
        else if (result.getError() != null) {  

            System.out.println("error:"+result.getError());   //i get error here.... 404
            throw new XMPPException(result.getError());
        }

// ---下面是我如何连接到openfire。

        ConnectionConfiguration config = new ConnectionConfiguration("localhost", 5222);
        config.setCompressionEnabled(true);
        config.setSASLAuthenticationEnabled(true);



        XMPPConnection connection = new XMPPConnection(config);
        // Connect to the server
        connection.connect();
        // Log into the server
        connection.login("test", "test","testresource");

我附上了从日志

Answer 1

我遇到了一个类似的问题，我刚刚解决了。

我在本地计算机上运行了一个Openfire服务器，我正在使用Smack API与服务器通信。在Openfire中，我定义了两个用户：发送者和接收者。我没有使用电子邮件地址作为用户名。

在我的代码中，我在一个线程上连接了“sender”，在一个单独的线程上连接了“receiver”。最初，在发送消息时，我收到了来自Openfire服务器的remote-server-not-found(404)错误响应。我发现，在发件人创建聊天请求时，我需要将参与者设置为receiver@[Openfire domain]。

因此，如果您的Openfire域名为 foo ，则为receiver@foo。显然，这不是“接收者”用户的电子邮件地址。通常，域实际上只是运行Openfire服务器的计算机的名称。

Answer 2

此错误由服务器生成（请参阅XMPPError）。我试着自己得到完全相同的错误代码，但失败了。但是，我觉得这是服务器的错误配置。您尝试与其他客户端连接，例如使用您最喜欢的Jabber客户端？

您还可以尝试启用Smacks XMPP调试功能并发布导致错误的消息：

static {
    XMPPConnection.DEBUG_ENABLED = true;
}

（您可能还想添加smackx-debug.jar以获得更多调试功能）

Answer 3

请检查数据包是否发送给了正确的用户！

您应该为iq数据包的“to”属性设置有效的JID，以便服务器可以将数据包发送到接收方。之前我收到此错误，因为我将错误的JID设置为数据包。

顺便说一句，您可以在代码中添加XMPPConnection.DEBUG_ENABLED = true，以查看您发送的内容或查看openfire Web控制台中的错误日志，您可能会发现以下错误：尝试连接到远程服务器时出错：theWrongHost（DNS查找：theWrongHost：5269）

openfire smack发送包404错误意味着什么？
