Smack_4_2_0.jar 使用

1. Android Studio依赖或者官网下载

  // XMPP通信  compile 'org.igniterealtime.smack:smack-im:4.2.0'  compile 'org.igniterealtime.smack:smack-tcp:4.2.0'  compile "org.igniterealtime.smack:smack-android-extensions:4.2.0"  compile "org.igniterealtime.smack:smack-android:4.2.0"

2. 服务器连接

/**   * 连接服务器   * @return 连接服务器对象   */  public void connect() {    try {      XMPPTCPConnectionConfiguration configuration =          XMPPTCPConnectionConfiguration.builder().setXmppDomain(XMPP_DOMAIN) // 设置域名              .setHostAddress(InetAddress.getByName(XMPP_HOST)) // 设置主机              .setPort(5222) // 设置端口              .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled) // 禁用SSL连接              .setCompressionEnabled(false) // 禁用SSL连接              //.setSendPresence(false) // 设置为离线状态              .setDebuggerEnabled(true) // 开启调试模式              .build();      // 设置需要经过同意才可以添加好友      Roster.setDefaultSubscriptionMode(Roster.SubscriptionMode.manual);      AbstractXMPPConnection connection = new XMPPTCPConnection(configuration);      connection.connect();// 连接, 可设置监听      connection.addConnectionListener(new XMPPConnectionListener());      this.mConnection = connection;    } catch (UnknownHostException e) {      e.printStackTrace();    } catch (XmppStringprepException e) {      e.printStackTrace();    } catch (InterruptedException | IOException | XMPPException | SmackException e) {      e.printStackTrace();    }  }

其中XMPPConnectionListener类实际上是实现ConnectionListener接口。

/** * 服务器连接监听 * Created by mazaiting on 2017/9/19. */public class XMPPConnectionListener implements ConnectionListener {  @Override public void connected(XMPPConnection connection) {}  @Override public void authenticated(XMPPConnection connection, boolean resumed) {}  @Override public void connectionClosed() {}  @Override public void connectionClosedOnError(Exception e) {}  @Override public void reconnectionSuccessful() {}  @Override public void reconnectingIn(int seconds) {}  @Override public void reconnectionFailed(Exception e) {}}

关闭连接则使用

  /**   * 关闭连接   */  public void disConnect() {    checkConnect();    if (mConnection.isConnected()) mConnection.disconnect();    mConnection = null;  }

3. 登录

  /**   * 登录服务器   * @param userName 用户名   * @param passWord 密码   * @return 是否登录成功。 true 成功; false 失败。   */  public boolean login(String userName, String passWord) {    checkConnect(); // 检查是否连接    try {      if (!mConnection.isAuthenticated()){ // 判断是否登录        mConnection.login(userName, passWord);        addListener(); // 设置一些监听        return true;      }      return false;    } catch (XMPPException | SmackException | InterruptedException | IOException e) {      Logger.e("登录出错");      e.printStackTrace();      return false;    }  }

4. 注册
   在注册时非安全链接，无法注册的情况，采取smack.jar内部代码，越过非安全链接的判断。

  /**   * 创建用户   * @param userName 用户名   * @param passWord 密码   * @param attributes 属性   */  public void createAccount(String userName, String passWord, Map<String, String> attributes)      throws SmackException.NotConnectedException, InterruptedException,      XMPPException.XMPPErrorException, SmackException.NoResponseException {    if (StringUtils.isNullOrEmpty(userName)) {      throw new IllegalArgumentException("Username must not be null");    }    if (StringUtils.isNullOrEmpty(passWord)) {      throw new IllegalArgumentException("Password must not be null");    }    attributes.put("username", userName); // 设置用户名    attributes.put("password", passWord); // 设置密码    Registration reg = new Registration(attributes);    reg.setType(IQ.Type.set); // 设置类型    reg.setTo(mConnection.getXMPPServiceDomain());// 设置发送地址    createStanzaCollectorAndSend(reg).nextResultOrThrow();  }  private StanzaCollector createStanzaCollectorAndSend(IQ req) throws      SmackException.NotConnectedException, InterruptedException {    StanzaCollector collector = mConnection.createStanzaCollectorAndSend(new StanzaIdFilter(req.getStanzaId()), req);    return collector;  }

5. 获取当前用户

  /**   * 获取当前用户   */  public EntityFullJid getCurrentUser() {    return mConnection.getUser();  }

6. 获取好友列表

  /***   * 获取好友列表   */  public void getFriendList() {    checkConnect();    Roster roster = Roster.getInstanceFor(mConnection);    Set<RosterEntry> entries = roster.getEntries();    Logger.e(entries.size() + "");    for (RosterEntry entry : entries) {      Logger.e(entry.toString());    }  }

7. 添加角色监听

  /**   * 添加关于角色的监听   */  private void addRosterListener() {    // 获取当前角色    Roster roster = Roster.getInstanceFor(mConnection);    // 接收到好友信息变化    mReceiverFriendStatusListener = new ReceiverFriendStatusListener();    roster.addRosterListener(mReceiverFriendStatusListener);    // 接收到添加好友信息    mAddFriendMessageListener = new AddFriendMessageListener();    roster.addSubscribeListener(mAddFriendMessageListener);  }/** * 获取到其他人添加自己的信息监听 * Created by mazaiting on 2017/9/19. */public class AddFriendMessageListener implements SubscribeListener {  @Override public SubscribeAnswer processSubscribe(Jid from, Presence subscribeRequest) {    // TODO添加好友请求    Logger.e("processSubscribe");    return null;  }}/** * 可以接收到其他人是否删除了自己,好友在线状态改变 * Created by mazaiting on 2017/9/19. */public class ReceiverFriendStatusListener implements RosterListener {  @Override public void entriesAdded(Collection<Jid> addresses) {    Logger.e("entriesAdded");  }  @Override public void entriesUpdated(Collection<Jid> addresses) {    Logger.e("entriesUpdated");  }  @Override public void entriesDeleted(Collection<Jid> addresses) {    Logger.e("entriesDeleted");  }  @Override public void presenceChanged(Presence presence) {    Logger.e("presenceChanged");  }}

8. 设置当前用户状态

  /**   * 设置在线、离线等状态   */  public void setOnLine(Presence.Type type) {    try {      checkConnect();      if (isOnLine != type) {        Presence presence = new Presence(type);        //presence.setStatus("Gone fishing");// 设置状态消息        mConnection.sendStanza(presence);        isOnLine = type;      }    } catch (Exception e) {      e.printStackTrace();    }  }
