Openfire jsjac构建webIM

在上一篇文章中,我们已经介绍如何用Openfire和jwchat构建webIM,但是我在搭建的过程中,总是感觉用户在登陆的时候速度非常慢,而且后期维护不好做

那么现在我在介绍一个比较简单的WebIM,在这个里面仅仅有几个简单的js,就可以完成和上面差不多的工作。

界面如下:

首先介绍一下项目的目录结构

一、准备工作

jsjac JavaScript lib下载:http://download.csdn.net/detail/zwdsmileface/8595845

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/

jquery.easydrag 下载:http://fromvega.com/code/easydrag/jquery.easydrag.js

jquery 下载:http://code.jquery.com/jquery-1.7.1.min.js

JabberHTTPBind jhb.jar 下载:http://download.csdn.net/detail/ibm_hoojo/4489188

二、核心代码演示

1、主界面(登陆、消息提示、日志、建立新聊天窗口)代码 index.jsp

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

// 建立一个聊天窗口应用,并设置发送者和消息接收者

remote.jsjac.chat.login(document.userForm);

});

});

var receiver = $("#sendTo").val();

// 建立一个新聊天窗口,并设置消息接收者(发送给谁?)

$.WebIM.newWebIM({

receiver: receiver

});

});

});

</script>

</head>

<body>

<!-- 登陆表单 -->

<form name="userForm" style="background-color: #fcfcfc; width: 100%;">

userName:<input type="text" name="userName" value="boy"/>

password:<input type="password" name="password" value="boy"/>

register: <input type="checkbox" name="register"/>

sendTo: <input type="text" id="to" name="to" value="hoojo" width="10"/>

<input type="button" value="Login" id="login"/>

</form>

<!-- 新窗口聊天 -->

<div id="newConn" style="display: none; background-color: #fcfcfc; width: 100%;">

User:<label></label>

sendTo: <input type="text" id="sendTo" value="hoojo" width="10"/>

<input type="button" value="new Chat" id="newSession"/>

<input type="button" value="Logout" id="logout"/>

</div>

<!-- 日志信息 -->

<div id="error" style="display: ; background-color: red;"></div>

<div id="info" style="display: ; background-color: #999999;"></div>

<!-- 聊天来消息提示 -->

<div class="chat-message">

<img src="images/write_icon.png" class="no-msg"/>

<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。
