WPF一步步开发XMPP IM客户端1：入门

[起因&目标]

因为工作原因接触openfire服务端和spark客户端开发，主要是基于openfire扩展开发了针对企业用途的服务器插件，还开发了各个平台上的客户端(Windows\mac\android\ios\linux)，详情可搜索微信公众号：CVTalk 

在开发过程中，发现基于Spark开发Java Swing客户端（公司内部命名CVTalk）比较重，用户体验很难做到和微信客户端看齐，皮肤的开发也比较费力，公司里绝大部分是windows的客户端，而且高清分辨率屏幕的用户越来越多, 那蚂蚁一样的小字和拥挤的布局改造很费劲，内存占用过多的问题也解决不了，swing客户端越发力不从心。

于是，我打算利用业余时间做一个 轻量级、易用、稳定、美观的Windows客户端。并抛砖引玉放开源：https://lightchat.codeplex.com/

 

坚持轻客户端，体验第一。 目标功能只有7个

1、  单聊

2、  群聊

3、  人员搜索

4、  消息搜索

5、  截屏传输

6、  文件传输

7、  插件扩展平台和企业业务集成接口，及xmpp少量扩展和服务器插件

 

特性：

• XMPP message、iq、presence、vcard、roster.....
• MUC(Multi-User Chat) support
• Fast localized(sqlite) user search,and Openfire ofUser import & sync
• Easy message search console
• Extensible organizational structure tree interface （Chinese users love it）
• HD resolution screen support
• ...

界面采用Modern UI。布局采用微信PC的方式，即搜索+联系人+聊天窗一体，不开新窗。

第一版的界面，单聊界面

消息搜索：

主要类介绍

 

1、Config.cs:全局设置类

//是否显示即时调试窗口        public static bool IsDebug = false;        public static String Version = "0.1";//@加上bareJid的域名部分        public static String Domain = "@im";//注意：这个是域名，一般为该服务器的机器名        public static String Server = "im";//外网或内网IP,目前AutoResolveConnectServer设置为true也不起作用，只能先改hosts文件        //public static readonly String ServerIP = "111.63.127.83";         public static readonly String ResourceName = "LightChat";        public static readonly bool IsCheckPresence = false;        public static readonly bool IsCheckChatState = false;        public static readonly bool AutoAgents = false;        public static readonly bool AutoPresence = true;        public static readonly bool AutoRoster = true;        //### 如果无法登陆，请在hosts文件中关联IP到Server域名 ###//C:\Windows\System32\drivers\etc\hosts  最后一行增加IP映射 比如 111.63.127.83 im        //自动解析connectserver属性，设置为true就会解析server属性即会利用System.Net.DNS.Resolve方法来将域名映射成ip地址        public static readonly bool AutoResolveConnectServer = false;        public static String MeCharacter = "我: ";        //### Organization structure data source definition  ###        //### 组织架构数据源定义 ###        //support：XML\Json\SqliteDB        //public static IDataSource OrgSource = new XmlDataSource();        public static IDataSource OrgSource = new DbDataSource();        //### User search data source ###        //### 用户搜索数据源 ###        public static IResultsProvider SearchSource = new UserSearchProvider();

用户搜索数据源，使用统一的返回结果接口IResultsProvider

public static IResultsProvider SearchSource = new UserSearchProvider();

 使用接口的目的是使业务代码具有扩展性，比如组织架构数据源实现松耦合的具体实现。

2、登陆类： LightChat.Pages.Login

代码

/// <summary>    /// Login.xaml 的交互逻辑    /// </summary>    public partial class Login : UserControl    {        public Login()        {            InitializeComponent();            //读取设置            this.Dispatcher.BeginInvoke(new Action(LoadSettings), null);

               return;            }            if (tbxPassword.Password == "")            {                ModernDialog.ShowMessage("注意：您的账户名未填写。", "提示", MessageBoxButton.OK);                return;            }            LoginXMPP();            SaveSettingsDB();        }        /// <summary>        /// 执行登录        /// </summary>        private void LoginXMPP()        {            XmppStatic.xmppCon = new XmppClientConnection();            XmppStatic.xmppCon.Server = Config.Server;

           try            {                //登录事件，异步                 XmppStatic.xmppCon.OnLogin += new ObjectHandler(xmppCon_OnLogin);                //socket断开事件                XmppStatic.xmppCon.OnClose += new ObjectHandler(xmppCon_OnClose);

           }            catch (Exception ex)            {                Console.WriteLine(ex.Message);            }                    }            private void xmppCon_OnClose(object sender)        {            this.Dispatcher.BeginInvoke(new Action(UIChangeOnClose), null);
