【问题描述】：

我有以下代码来开始两个用户之间的聊天对话：

               // Create Connection.
                Connection.DEBUG_ENABLED = true;
                config     = new ConnectionConfiguration(CHAT_SERVER);
                connection = new XMPPConnection(config);
                connection.connect();
                connection.login(chatLogin, password);

                // Create Chat Manager.
                chatManager = connection.getChatManager();

                // Create Chat.
                chat = chatManager.createChat(friendLogin, messageListener);

                // Set listener for outcoming messages.
                chatManager.addChatListener(chatManagerListener);

                String str_your_chat_id     = Integer.toString(your_chat_id);
                String str_receiver_chat_id = Integer.toString(receiver_chat_id);

                // Set Subscription to receive user status
                Presence subscribe = new Presence(Presence.Type.subscribe);
                subscribe.setTo(str_your_chat_id +"[e-mail]");
                connection.sendPacket(subscribe);

                Presence subscribed = new Presence(Presence.Type.subscribed);
                subscribed.setTo(str_receiver_chat_id +"[e-mail]");
                connection.sendPacket(subscribed);


                subscribe = new Presence(Presence.Type.subscribe);
                subscribe.setTo(str_receiver_chat_id +"[e-mail]");
                connection.sendPacket(subscribe);


                subscribed = new Presence(Presence.Type.subscribed);
                subscribed.setTo(str_your_chat_id +"[e-mail]");
                connection.sendPacket(subscribed);

但是当它运行来自 asmack 服务器的消息时，会响应“你不能订阅自己”。

有人知道我做错了什么吗？

【参考方案1】：

这段代码有问题：

            // Set Subscription to receive user status
            Presence subscribe = new Presence(Presence.Type.subscribe);
            subscribe.setTo(str_your_chat_id +"[e-mail]");
            connection.sendPacket(subscribe);

您为自己订阅，但您没有

很高兴听到您想要实现的目标
