asmack xmpp应用遇到的问题

项目中遇到要用xmpp做通讯，原来在的应用跑在linux上用的gloox，现在需要在android上来实现，查了下发现smack最近做了一次大升级，4.0.0发布了，最开始用了smack的库，结果在android上报错，去https://community.igniterealtime.org/ 社区问了下，原来还有个asmack，下了库文件然后写代码：

根据asmack-android-8-4.0.0-rc2.jar 的readme，另外需要dnsjava的库，我用的是dnsjava-2.1.6

最开始发现logcat有一个关于dns的报错，网上查了下发现有说要加下面一句在初始化的时候：

//System.setProperty("sun.net.spi.nameservice.provider.1","dns,dnsjava");

但是后来我发现没有这句，好像也没问题，暂时屏蔽掉了。

asmack的初始化是必须的。

mSmackAndroid = SmackAndroid.init(context);

conf = new ConnectionConfiguration( "wooxonline.com",5222);

SASLAuthentication.supportSASLMechanism("PLAIN",0);

conf.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);

conf.setCompressionEnabled(false);

// disable the built-in ReconnectionManager since we handle this

conf.setReconnectionAllowed(false);

conf.setSendPresence(false);

conf.setDebuggerEnabled(true);

XMPPConnection connection = XMPPTCPConnection(conf);

connection.login(g_email, g_password);

最开始少了sasl方式的设置，发现连接没问题，但是login的时候总是返回noresponse error，查了发现asmask对于连接出错抛的异常比较简单，不会细分。

log如下：

在注册新用户的时候，可以使用accountmanager也可以使用IQ package，方法如下：

public static final int REGISTER_METHOD_ACCOUNT_MANAGER = 0;

public static final int REGISTER_METHOD_IQ_PACKAGE = 1;

public static final int REGISTER_RESULT_SERVER_NO_RESULT = 0;

public static final int REGISTER_RESULT_SUCCESS = 1;

public static final int REGISTER_RESULT_ACCOUNT_EXIST = 2;

public static final int REGISTER_RESULT_FAIL = 4;

public static final int REGISTER_RESULT_NO_CONNECTION = 4;

/**

* register

* @param username

* @param password

* @return 1:success 0:server not return 2:account exist 3:fail 4:no connection

public int register(String username, String password) {

if (!((mConnection != null) && mConnection.isConnected())) {

return REGISTER_RESULT_NO_CONNECTION;

} else {

reg_method = REGISTER_METHOD_ACCOUNT_MANAGER;

Map<String, String> attributes = new HashMap<String, String>();

attributes.put("username", username);

attributes.put("password", password);

//attributes.put("email", "");

//attributes.put("name", "");

if (reg_method == REGISTER_METHOD_ACCOUNT_MANAGER) {

try {

if (mAccountManager == null) {

mAccountManager = AccountManager.getInstance(mConnection);

}

mAccountManager.createAccount(username, password, attributes);

} catch (Exception ex) {

L.e(TAG, ex);

if (ex.toString().equalsIgnoreCase("conflict")) {

L.i(XmppManager.class, " account exist!");

return REGISTER_RESULT_ACCOUNT_EXIST;

} else {

L.i(XmppManager.class, " register fail");

return REGISTER_RESULT_FAIL;

}

L.i(XmppManager.class, " register success!");

return REGISTER_RESULT_SUCCESS;

} else if (reg_method == REGISTER_METHOD_IQ_PACKAGE) {

try {

Registration reg = new Registration();

reg.setType(IQ.Type.SET);

reg.setTo(mConnection.getServiceName());

reg.setAttributes(attributes);

PacketFilter filter = new AndFilter(new PacketIDFilter(reg.getPacketID()),

new PacketTypeFilter(IQ.class));

PacketCollector collector = mConnection.createPacketCollector(filter);

mConnection.sendPacket(reg);

IQ result = (IQ) collector.nextResult(SmackConfiguration.getDefaultPacketReplyTimeout());

collector.cancel();

//System.out.println(result);

if (result == null) {

L.i(XmppManager.class, " no value return by server!");

return REGISTER_RESULT_SERVER_NO_RESULT;

} else if (result.getType() == IQ.Type.ERROR) {

//<error code="409" type="cancel"><conflict xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/></error>

if (result.getError().toString().equalsIgnoreCase("conflict")) {

L.i(XmppManager.class, " account exist!");

return REGISTER_RESULT_ACCOUNT_EXIST;

} else {

L.i(XmppManager.class, " register fail");

return REGISTER_RESULT_FAIL;

}

} else if (result.getType() == IQ.Type.RESULT) {

L.i(XmppManager.class, " register success!");

//Intent intent = new Intent(DaemonService.ACTION_REGISTER);

return REGISTER_RESULT_SUCCESS;

}

L.e(TAG, ":Should not go there for register process!");

} catch (Exception ex) {

L.e(TAG, ex);

}

L.e(TAG, ":Should not go there for register process!");

return REGISTER_RESULT_FAIL;

}

当账户存在时，返回如下包：

D/SMACK﹕ RCV (0): <iq type="error" id="EzQN5-0" from="ddnas-v2.com" to="ddnas-v2.com/c220b282"><query xmlns="jabber:iq:register"><email> </email><password>jacky</password><username>jacky</username><name> </name></query><error code="409" type="cancel"><conflict xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/></error></iq>

但是geterrorcode()接口似乎在4.0的asmack中被去掉了，所以只能判定error是conflict就认为是账户已经存在。

由于服务器强制使用TLS认证，所以对于连接做了新的配置，然后再openfire server上测试没有问题，但是在公司的服务器出问题了，最先我用的是asmak 4.0.0 rc2的库，在认证challenge的时候服务器似乎没有响应，log如下：

翻了一下asmack社区的帖子https://community.igniterealtime.org/message/240015#240015上说rc3的库解决了这个问题，down下来一试，果然，但是认证还是通不过：
