服务器端开启监听5222端口
{
////
allDone.Reset();
// Start an asynchronous socket to listen for connections.
Console.WriteLine("等待连接
![](https://www.cnblogs.com/Images/dot.gif)
listener.BeginAccept(new AsyncCallback(AcceptCallback), null);
//// 等待客户端连接
allDone.WaitOne();
}
如果收到客户端请求就异步调用AcceptCallback初始化套接字连接
,并为客户端建立一个通信线程,新建初始化套接字连接采用异步调
用读取套接字信息
: this()
{
m_Sock = sock;
m_Sock.BeginReceive(buffer, 0, BUFFERSIZE, 0, new AsyncCallback(ReadCallback), null);
m_Sock.SendTimeout = 100;
}
客户端与服务器端的交互过程
1客户端异步向服务器端发送连接请求
<stream:stream to='localhost' xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' version='1.0' xml:lang='en'>
2服务器端收到请求,初始化回应流,并随机生成一相SessionID
<stream:stream xmlns:stream="http://etherx.jabber.org/streams" from="localhost" id="30e3b
3等待服务器返回消息后客户端发送用户名(由于在客户端采用了异步调用
方式,所以UI界面感觉不到等待)
<iq xmlns="jabber:client" id="agsXMPP_1" type="get" to="localhost">
<query xmlns="jabber:iq:auth"><username>test</username></query></iq>
4服务器端收到用户名等待用户提供密码
<iq xmlns="jabber:client" from="localhost" type="result" id="agsXMPP_1">
<query xmlns="jabber:iq:auth"><username>test</username><password />
<digest /></query></iq>
5客户端提供加密后的密码
<iq xmlns="jabber:client" id="agsXMPP_2" to="localhost" type="set">
<query xmlns="jabber:iq:auth"><username>test</username>
<digest>e66557d2b67256bf7e9b
<resource>MiniClient</resource></query></iq>
6服务器端从数据库验证用户名和密码,并返回结果
iq xmlns="jabber:client" from="localhost" type="result" id="agsXMPP_2" />
7如果返回错误,客户端提示并终断连接,否则客户端发送响应数据
8 服务器端返回数据
9 客户端发送状态,
10服务器收到状态,发送IQ节并通知其它用户.
