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,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

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

开发环境

  • System:Windows
  • JavaEE Server:Tomcat 5.0.28+/Tomcat 6
  • WebBrowser:IE6+、Firefox3.5+、Chrome 已经兼容浏览器
  • JavaSDK:JDK 1.6+
  • Openfire 3.7.1
  • IDE:eclipse 3.2、MyEclipse 6.5

开发依赖库

  • jdk1.4+
  • serializer.jar
  • xalan.jar
  • jhb-1.0.jar
  • log4j-1.2.16.jar

jhb-1.0.jar 这个就是 JabberHTTPBind,我把编译的 class 打成 jar 包了

JavaScript lib

jquery.easydrag.js 窗口拖拽 JavaScript lib
jquery-1.7.1.min.js jquery lib
jsjac.js 通信核心库
local.chat-2.0.js 本地会话窗口发送消息 JavaScript 库
remote.jsjac.chat-2.0.js 远程会话消息 JavaScript 库
send.message.editor-1.0.js 窗口编辑器 JavaScript 库

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/

        // 建立一个聊天窗口应用,并设置发送者和消息接收者

    <img src="images/write_icon.gif" class="have-msg" style="display: none;"/>
  </div>
  </body>
</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

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。
