简单的im聊天程序
由于项目需要做一个基于xmpp协议的android通讯软件。故开始研究xmpp。
xmpp协议采用的是客户端-服务器架构,所有从一个客户端发到另一个客户端的消息和数据都必须经过xmpp服务器转发,而且支持服务器间dns的路由,也就是说可以构建服务器集群,使不同的

服务器下的客户端也可以通信,xmpp的前身是一个开源组织制定的网络通信协议——jabber,xmpp的核心是在网络上分片段发送xml流的协议,这个协议是xmpp的即时通讯指令的传递手段。
      为了防止服务器间发送的数据被篡改或偷听,xmpp服务器通信引入了tls机制,使用tls机制能实现数据的加密,从而保证了在数据传输过程种数据的安全。
      一个xmpp实体的地址称为jabber identifier或jid,作用类似于ip地址。一个合法的jid包括节点名,域名资源名,其格式为:jid=[node'@']domain['/'resource]

xmpp协议的命名空间:

  • jabber:iq:private   -- 私有数据存储,用于本地用户私人设置信息,比如用户备注等。
  • jabber:iq:conference  -- 一般会议,用于多个用户之间的信息共享
  • jabber:x:encrypted -- 加密的消息,用于发送加密消息
  • jabber:x:expire  -- 消息终止
  • jabber:iq:time  -- 客户端时间
  • jabber:iq:auth  -- 简单用户认证,一般用于服务器之间或者服务器和客户端之间的认证
  • jabber:x:roster  -- 内部花名册
  • jabber:x:signed  -- 标记的在线状态
  • jabber:iq:search -- 用户数据库查询,用于向服务器发送查询请求
  • jabber:iq:register -- 注册请求,用于用户注册相关信息
  • jabber:x:iq:roster -- 花名册管理
  • jabber:x:conference -- 会议邀请,用于向参加会议用户发送开会通知
  • jabber:x:event  -- 消息事件
  • vcard-temp  -- 临时的vcard,用于设置用户的头像以及昵称等

 在网上找了下,有开源的项目beem,开源的用于android的xmpp框架asmack,asmack是smack的android版本。现在开始学习smack

。xmpp就是神马东西,就不废话了。首先在网上下一个openfire和spack,不知道这两个是什么东西,就直接google吧。安装openfire需要mysql的支持,当然,oracle,sqlserver肯定是可以的。还是先上图吧:

openfire + spark + myxmppp

        } catch (exception e) { 
          e.printstacktrace(); 
        } 
  } 
} 

以上代码如果在一般的java project上运行需要加入smack.jar 和klmx2.jar,如果是android project,基本代码不需改变只需将其放入oncreate(...)方法下即可,需要加入asmack.jar包.

1、connectionconfiguration
 作为用于与xmpp服务建立连接的配置。它能配置;连接是否使用tls,sasl加密。
 包含内嵌类:connectionconfiguration.securitymode

2、xmppconnection.
 xmppconnection这个类用来连接xmpp服务.
 可以使用connect()方法建立与服务器的连接。disconnect()方法断开与服务器的连接.
 在创建连接前可以使用xmppconnection.debug_enabled = true; 使开发过程中可以弹出一个gui窗口,用于显示我们的连接与发送packet的信息。

Android中基于XMPP协议实现IM聊天程序与多人聊天室

3、chatmanager
 用于监控当前所有chat。可以使用createchat(string userjid, messagelistener listener)创建一个聊天。
 
4、chat
 chat用于监控两个用户间的一系列message。使用addmessagelistener(messagelistener listener)当有任何消息到达时将会触发listener的processmessage(chat chat, message message)
方法.
 我们可以使用sendmessage()发送消息,这个方法有两个重载方法,一种类类型的参数时string类型,另一种则是传入message对象(后面介绍)。
 那么有这样一种情况,当别人主动跟我们建立连接发送消息,或者系统发送消息时我们怎么才能接收消息呢?
    我现在是这样操作的:

 chatmanager.addchatlistener(new chatmanagerlistener() {
 @override
 public void chatcreated(chat chat, boolean createdlocally) {
  chat.addmessagelistener(new messagelistener() {
  @override
  public void processmessage(chat chat, message message) {
   system.out.println("received message: " + message.getbody());
  }
     
  });
 }
 });

 
5、message

  •  message用于表示一个消息包(可以用调试工具看到发送包和接收包的具体内容)。它有以下多种类型。
  •   message.type.normal -- (默认)文本消息(比如邮件)
  •   message.type.chat -- 典型的短消息,如qq聊天的一行一行显示的消息
  •   message.type.group_chat -- 群聊消息
  •   message.type.headline -- 滚动显示的消息
  •   message.type.error -- 错误的消息
  •  message有两个内部类:
  •   message.body -- 表示消息体
  •   message.type -- 表示消息类型

6、roster
 表示存储了很多rosterentry的一个花名册.为了易于管理,花名册的项被分贝到了各个group中.
 当建立与xmpp服务的连接后可以使用connection.getroster()获取roster对象。
 别的用户可以使用一个订阅请求(相当于qq加好友)尝试订阅目的用户。可以使用枚举类型roster.subscriptionmode的值处理这些请求:
 accept_all: 接收所有订阅请求
 reject_all:拒绝所有订阅请求
 manual:  手工处理订阅请求
 
 创建组:rostergroup group = roster.creategroup("大学");
 向组中添加rosterentry对象: group.addentry(entry);
 
7、rosterentry
 表示roster(花名册)中的每条记录.它包含了用户的jid,用户名,或用户分配的昵称.
 
8、rostergroup
 表示rosterentry的组。可以使用addentry(rosterentry entry)添加。contains(string user) 判断某用户是否在组中.当然removeentry(rosterentry entry)就是从组中移除了。getentries()

获取所有rosterentry.
 
9、presence
 表示xmpp状态的packet。每个presence packet都有一个状态。用枚举类型presence.type的值表示:
 available -- (默认)用户空闲状态
 unavailable -- 用户没空看消息
 subscribe -- 请求订阅别人,即请求加对方为好友
 subscribed -- 统一被别人订阅,也就是确认被对方加为好友
 unsubscribe -- 他取消订阅别人,请求删除某好友
 unsubscribed -- 拒绝被别人订阅,即拒绝对放的添加请求
 error -- 当前状态packet有错误
 内嵌两个枚举类型:presence.mode和presence.type.
 可以使用setstatus自定义用户当前的状态(像qq一样的)

上面有两张spark客户端的聊天室列表占有者一列不同的原因:当使用以下代码获取时不能获取occupantscount和subject的值:  

system.out.println(roominfo.getoccupantscount() + " : " + roominfo.getsubject()); 

这是由于openfire端有个bug(暂且这样说吧,我不知为什么openfire这样做).首先修改smack的一个bug,修改roominfo类的roominfo(discoverinfo info) 方法:         

iterator<string> values = form.getfield("muc#roominfo_subject").getvalues(); 
if (values.hasnext()) { 
  this.subject = values.next(); 
} 
else { 
  this.subject = ""; 
} 
 

改为:   

final formfield subjfield = form.getfield("muc#roominfo_subject");  
this.subject = subjfield == null ? "" : subjfield.getvalues().next(); 

  修改openfire的源码,org/jivesoftware/openfire/muc/spi/multiuserchatserviceimpl类的public dataform getextendedinfo(string name, string node, jid senderjid) 方法:         

      /*final formfield fieldocc = dataform.addfield(); */ 
      fieldsubj.setvariable("muc#roominfo_occupants"); 
      fieldsubj.setlabel(localeutils.getlocalizedstring("muc.extended.info.occupants")); 
      fieldsubj.addvalue(integer.tostring(room.getoccupantscount())); 

  
改为:         

final formfield fieldoccu= dataform.addfield(); 
fieldoccu.setvariable("muc#roominfo_occupants"); 
fieldoccu.setlabel(localeutils.getlocalizedstring("muc.extended.info.occupants")); 
fieldoccu.addvalue(integer.tostring(room.getoccupantscount()));
