JavaScript/jQuery、HTML、CSS 构建 Web IM 远程及时聊天通信程序

这篇文章主要介绍用JavaScript和jQuery、HTML、CSS以及用第三方聊天JavaScript（jsjac）框架构建一个BS Web的聊天应用程序。此程序可以和所有连接到Openfire服务器的应用进行通信、发送消息。如果要运行本程序还需要一个聊天服务器Openfire，

以及需要用到Http方式和Openfire通信的第三方库（JabberHTTPBind）。

JabberHTTPBind是jabber提供的XMPP协议通信的Http bind发送的形式，它可以完成WebBrowser和Openfire建立长连接通信。

主要通信流程如下图所示：

用户A通过JavaScript jsjac.js库发送一条消息到JabberHTTPBind这个Servlet容器，然后JabberHTTPBind的Servlet容器会向Openfire发送XMPP协议的XML报文。Openfire Server接收到报文后解析，然后发送给指定的用户B。JabberHTTPBind获取到Openfire Server发送的数据后，解析报文向当前Servlet容器中的链接的Session中找到指定的用户再发送数据给用户B。

WebBrowser端用的是jsjac和JabberHTTPBind建立的连接，所有数据都要经过JabberHTTPBind解析/转换发送给Openfire。

先上张图看看效果，呵呵~这里是用户hoojo和girl的聊天画面，双方在进行互聊……

可以发送表情、改变字体样式（对方界面也可以看到你的字体样式），同时右侧是显示/收缩详情的信息

收缩详情

聊天界面部分截图

用户登录、注册，sendTo表示你登录后向谁发送聊天消息、并且建立一个聊天窗口

登录成功后，你可以在日志控制台看到你的登陆状态、或是在firebug控制台中看到你的连接请求状态

登陆失败

只有connecting，就没有下文了

登陆成功后，你就可以给指定用户发送消息，且设置你想发送消息的新用户点击new Chat按钮创建新会话

如果你来了新消息，在浏览器的标题栏会有新消息提示

如果你当前聊天界面的窗口都是关闭状态，那么在右下角会有消息提示的闪动图标

这里已经贴出了所有的源代码了，如果你非常的需要源代码（但我希望你能自己创建一个工程去复制源代码，这是我希望看到的），那么你可以通过以下方式联系我

注：我不会保证在第一时间给你代码，但我会在空闲的时间给你发送源码

导读

如果你对openfire还不是很了解或是不知道安装，建议你看看这2篇文章

因为这里还用到了JabberHTTPBind 以及在使用它或是运行示例的时候会遇到些问题，那么你可以看看这篇文章

一、准备工作

jsjac JavaScript lib下载：https://github.com/sstrigler/JSJaC/

如果你不喜欢用jsjac JavaScript lib和Openfire通信，那么有一款jQuery的plugin可以供你使用，下载地址

jQuery-XMPP-plugin https://github.com/maxpowel/jQuery-XMPP-plugin

这里有所以能支持Openfire通信的第三方库，有兴趣的可以研究下 http://xmpp.org/xmpp-software/libraries/

</html>

下面这段代码尤为重要，它是设置你链接openfire的地址。这个地址一段错误你将无法进行通信！
<script type="text/javascript">
    window.contextPath = "<%=path%>";
    window["serverDomin"] = "192.168.8.22";
</script>

$.WebIM方法是主函数，用它可以覆盖local.chat中的基本配置，它可以完成聊天窗口的创建。$.WebIM.newWebIM方法是新创建一个窗口，只是消息的接收者是一个新用户。
$.WebIM({
    sender: userName,
    receiver: receiver
});
 
$.WebIM.newWebIM({
    receiver: receiver
});

remote.jsjac.chat.login(document.userForm);方法是用户登录到Openfire服务器

参数如下：
httpbase: window.contextPath + "/JHB/", //请求后台http-bind服务器url
domain: window["serverDomin"], //"192.168.5.231", // 192.168.5.231 当前有效域名
username: "", // 登录用户名
pass: "", // 密码
timerval: 2000, // 设置请求超时
resource: "WebIM", // 链接资源标识
register: true // 是否注册
remote.jsjac.chat.logout();是退出、断开openfire的链接

    $.WebIM.newWebIM = _opts.newWebIM;

    $.WebIM.messageHandler = _opts.messageHandler;

})(jQuery);

这里的方法基本上是聊天窗口上的应用，主要是本地聊天程序的js、HTML元素的操作。如字体、字体大小、颜色、表情、消息的发送等，不涉及到聊天消息发送的核心代码，其中有用到发送远程消息的方法。

remote.jsjac.chat.sendMessage(text, receiver); 这个是发送远程消息的方法，参数1是消息内容、参数2是消息的接收者

如果你有看到这篇文章http://www.cnblogs.com/hoojo/archive/2012/06/18/2553886.html 它是一个单纯的WebIM本地的聊天界面。

3、远程聊天JavaScript核心代码，它是和jsjac库关联的。
