java - openfire smack发送包404错误是什么意思？

Question

当使用 Smack 将数据包发送到 openfire 时，我收到错误 remote-server-not-found(404) 。谁能解释一下错误是什么意思？是连接服务器失败还是数据包有问题？

        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());
        }

//--- 以下是我如何连接到 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");

我附上了我从日志中收到的 xmpp xml

正在发送....

我遇到了一个类似的问题，最近才解决。

我有一个 Openfire 服务器在我的本地计算机上运行，​​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，我在一个线程上有一个“发送者”连接，在一个单独的线程上有一个“接收者”连接。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，在发送方创建聊天请求时，我需要将参与者设置为receiver@[Openfire domain]。

因此，如果您的 Openfire 域是 foo，它将是 receiver@foo。显然，这不是“接收方”用户的电子邮件地址。通常，域实际上只是运行 Openfire 服务器的机器的名称。
