Smack的API应用

===============================================================
主动发送信息给某个用户
------------------------------------
XMPPConnection.DEBUG_ENABLED = true ;
//设置服务器地址
XMPPConnection conn = new XMPPConnection( "127.0.0.1" );
conn.connect();
//输入账号和密码登陆
conn.login("[email protected]" , "123456" );
//创建一个和test1的对话，并设置信息监听
Chat mychat = conn.getManager().create("[email protected]" ,
new MessageListener() {
@Override
public void processMessage(Chat chat,, Message message) {
String messageBody = message.getBody();
System.out.println("收到信息：" +messageBody);
}
});
//发送给test1文本信息
mychat.sendMessage("hello" );
//退出登陆
conn.disconnect();
===============================================================
设置自己的登陆状态
------------------------------------
XMPPConnection.DEBUG_ENABLED = true ;
//设置服务器地址
XMPPConnection conn = new XMPPConnection( "127.0.0.1" );
conn.connect();
//输入账号和密码登陆
conn.login("[email protected]" , "123456" );
//设置登陆后的个人状态信息
Presence p = new Presence(Presence.Type.available);
p.setStatus("发呆中。。。" );
conn.sendPacket(p);
//退出登陆
conn.disconnect();
==========================================================================
被动接收用户发来的信息
------------------------------------
XMPPConnection.DEBUG_ENABLED = true ;
//设置服务器地址
XMPPConnection conn = new XMPPConnection( "127.0.0.1" );
conn.connect();
//输入账号和密码登陆
conn.login("[email protected]" , "123456" );
//设置信息的监听
conn.getChatManager().addChatListener(new ChatManagerListener() {
@Override
public void chatCreated(Chat chat, boolean createdLocally) {
chat.addMessageListener(new MessageListener() {
@Override
public void processMessage(Chat chat, Message message) {
String messageBody = message.getBody();
System.out.println("接收到信息：" +messageBody);
}
});
}
});
//退出登陆
conn.disconnect();
==========================================================================
获取我的好友列表
------------------------------------
//设置服务器地址
XMPPConnection conn = new XMPPConnection( "127.0.0.1" );
conn.connect();
//输入账号和密码登陆
conn.login("[email protected]" , "123456" );
Collection<RosterEntry> rosters = conn.getRoster().getEntries();
System.out.println("我的好友列表：=======================" );
for (RosterEntry rosterEntry : rosters){
System.out.print("name: " +rosterEntry.getName()+ ",jid: " +rosterEntry.getUser());
System.out.println("" );
}
System.out.println("我的好友列表：=======================" );
conn.disconnect();
==========================================================================
聊天窗口输入状态，使用XEP-0085 协议
------------------------------------
//发送给test1初始文本信息,附带输入状态
Message mess = new Message();
mess.addExtension(new ChatStateExtension(ChatState.active));
mychat.sendMessage(mess);
//发送给test1初始文本信息,附带正在输入的状态
Message mess = new Message();
mess.addExtension(new ChatStateExtension(ChatState.composing));
mychat.sendMessage(mess);
//发送给test1初始文本信息,附带暂停输入的状态
Message mess = new Message();
mess.addExtension(new ChatStateExtension(ChatState.paused));
mychat.sendMessage(mess);
//其他略。。。
//接收的时候
public void processMessage(Chat chat, Message message) {
String messageBody = message.getBody();
PacketExtension pe;
pe = message.getExtension("composing" , "http://jabber.org/protocol/chatstates" );
if (pe != null ){
System.out.println("对方正在输入......" );
}
pe = message.getExtension("active" , "http://jabber.org/protocol/chatstates" );
if (pe != null ){
System.out.println("接收到信息：" +messageBody);
}
pe = message.getExtension("paused" , "http://jabber.org/protocol/chatstates" );
if (pe != null ){
System.out.println("对方已暂停输入" );
}
pe = message.getExtension("inactive" , "http://jabber.org/protocol/chatstates" );
if (pe != null ){
System.out.println("对方聊天窗口失去焦点" );
}
pe = message.getExtension("gone" , "http://jabber.org/protocol/chatstates" );
if (pe != null ){
System.out.println("对方聊天窗口被关闭" );
}
}
==========================================================================
接收邀请，加入多人聊天房间
------------------------------------
MultiUserChat.addInvitationListener(conn, new InvitationListener() {
@Override
public void invitationReceived(XMPPConnection conn, String room,
String inviter, String reason, String password, Message message) {
MultiUserChat multiUserChat = new MultiUserChat(conn, room);
System.out.println("收到来自 " +inviter+ " 的聊天室邀请。邀请附带内容：" +reason);
try {
multiUserChat.join("test2" , password);
} catch (XMPPException e) {
System.out.println("加入聊天室失败" );
e.printStackTrace();
}
System.out.println("成功加入聊天室" );
multiUserChat.addMessageListener(new PacketListener() {
@Override
public void processPacket(Packet packet) {
Message message = (Message)packet;
//接收来自聊天室的聊天信息
System.out.println(message.getFrom()+":" +message.getBody());
}
});
}
//发送信息到聊天室
multiUserChat.sendMessage("新手到来，大家关照！" );
});
