java - XMPP Smack 无法接收消息

Question

我读了很多关于如何通过 smack 4.1 发送和接收消息的相关帖子 和开火。根据我的理解，我实现了以下代码

我可以连接，我可以登录。但是当发送消息表单 user1 到 user2 时，我什么也没得到。

代码:

提前谢谢您!

Answer 1

快速浏览一下代码，发现了一些错误:

1. createChat 期望第一个参数是 userJid(不是主机 IP)

   Chat newChat = chatmanager.createChat("ehsan@<service name>" ,new ChatMessageListener() {
       @Override
       public void processMessage(Chat chat, Message message) {
           Log.d("","message :"+  message.getBody());
       }
   });  
   

2. 启用调试并检查日志

   connection = new XMPPTCPConnection(
           XMPPTCPConnectionConfiguration.builder()
                   .setServiceName("192.168.1.6")
                   .setUsernameAndPassword("ehsan", "123")
                   .setPort(9090)
                   .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
                   .setCompressionEnabled(false)
                   .setDebuggerEnabled(true)
                   .build());
   

3. 将端口从 9090 更改为 5222(如果您没有更改默认配置；请检查 openfire 管理面板)

4. 首选使用 addAsyncStanzaListener 监听传入数据包。
