msg.data = st;
foreach (TcpChannel item in channel.Server.GetOnlines())
{
item.Send(msg);
}
}
}
只需要以上简单的代码就完成了聊天室服务端的功能，对于用户退出可以通过连接释放事件来做处理具体代码：
protected override void OnDisposed(object sender, ChannelDisposedEventArgs e) {
base.OnDisposed(sender, e);
Console.WriteLine("{0} disposed", e.Channel.EndPoint);
JsonMessage msg = new JsonMessage();
User user = new User();
user.Name = e.Channel.Name;
user.ID = e.Channel.ClientID;
user.IP = e.Channel.EndPoint.ToString();
msg.type = "unregister";
msg.data = (User)e.Channel.Tag;
foreach (TcpChannel item in this.Server.GetOnlines())
{
if (item != e.Channel)
item.Send(msg);
}
}
这样聊天定的服务端代码就已经完成了．
JavaScript代码
对于html5代码首先要做的一件事就是连接到服务器，相关javascript
function connect() { channel = new TcpChannel();
channel.Connected = function (evt) {
callRegister.parameters.name = $('#nikename').val();
channel.Send(callRegister, function (result) {
if (result.status == null || result.status == undefined) {
$('#dlgConnect').dialog('close');
registerid = result.data;
list();
}
});
};
channel.Disposed = function (evt) {
$('#dlgConnect').dialog('open');
};
channel.Error = function (evt) {
alert(evt);
};
channel.Receive = function (result) {
if (result.type == "register") {
var item = getUser(result.data);
$(item).appendTo($('#lstOnlines'));
}
else if (result.type == 'unregister') {
$('#user_' + result.data.ID).remove();
}
else if (result.type == 'say') {
addSayItem(result.data);
}
else {
}
}
channel.Connect($('#host').val());
}
通过Receive回调池数来处理不同消息的情况，如果是接收到其他用户的注册信息，则把用户信息添加到列表中；如果收到的其他用户的退出信息则在用户列表种移走；直接收到消息添加到消息显示框中即可．有jquery的帮助以上事件都变得非常简单．
用户注册调用过程:
var callRegister = { url: 'Handler.Register', parameters: { name: ''} }; function register() {
$('#frmRegister').form('submit', {
onSubmit: function () {
var isValid = $(this).form('validate');
if (isValid) {
connect();
}
return false;
}
});
}
获取在线用户列表过程:
var callList = { url: 'Handler.List', parameters: {} };
