我使用smack 4.1.7作为我在android上的xmpp库和openfire作为我的服务器。一旦设备从飞行模式上线，我尝试强力重新连接时会出现异常。在正常的工作流程中，我没有得到这个例外。我希望我的应用程序支持离线模式，因此我必须确保从离线模式到在线模式的平稳过渡。我使用飞行模式来测试这种情况。
我正在使用重新连接管理器以20秒的固定延迟处理重新连接。我强制重新连接，因为如果用户已经在应用程序中，我不希望用户等待20秒以进行xmpp重新连接。这就是为什么我依靠重新连接管理器仅在应用程序处于后台时才重新连接。我希望这有助于理解我在这里要做的事情。
我在Android上启用Smack调试模式发布堆栈跟踪：

如果我从日志中正确理解，当我尝试在网络更改事件中立即重新连接时，当设备从飞行模式连接到互联网时，我会收到异常。但它最终会通过重新连接管理器进行连接。我用来触发xmpp connect和login的代码如下：
// The network monitor
private BroadcastReceiver networkMonitor = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
if (isOnline && !Utilities.isOnline(AbstractActivity.this)) {
isOnline = false;
} else if (!isOnline && Utilities.isOnline(AbstractActivity.this)) {
// Trigger only when going from offline to online
isOnline = Utilities.isOnline(AbstractActivity.this);
// Re-establish the xmpp connection if it was disconnected
if (isOnline ) {
connectAndAuthenticate();
}
}
}
};
public void connectAndAuthenticate() {
if(xmppConnection==null){
XMPPTCPConnectionConfiguration.Builder builder = XMPPTCPConnectionConfiguration.builder()
.setUsernameAndPassword(hashedUserName, getPassword())
.setServiceName(serviceName)
.setHost(getCoreServer())
.setSendPresence(true)
.setSecurityMode(ConnectionConfiguration.SecurityMode.required)
.setPort(Integer.parseInt(port))
.setResource(getDeviceID());
if (BuildConfig.DEBUG) {
builder.setDebuggerEnabled(true);
}
XMPPTCPConnectionConfiguration config = builder.build();
xmppConnection = new MVXMPPTCPConnection(config);
// Disable the roster
Roster.getInstanceFor(xmppConnection).setRosterLoadedAtLogin(false);
ReconnectionManager reconnectionManager = ReconnectionManager.getInstanceFor(xmppConnection);
reconnectionManager.enableAutomaticReconnection();
reconnectionManager.setReconnectionPolicy(ReconnectionManager.ReconnectionPolic y.FIXED_DELAY);
reconnectionManager.setFixedDelay(20);
PingManager pingManager = PingManager.getInstanceFor(xmppConnection);
pingManager.registerPingFailedListener(this);
pingManager.setPingInterval(60);
// Instantiates a ChatStateManager.
ChatStateManager.getInstance(xmppConnection);
}
// connect
try {
Log.i(TAG, "Before xmppConnection connect.....");
xmppConnection.connect();
Log.i(TAG, "After xmppConnection connect.....");
} catch (SmackException.AlreadyConnectedException e) {
e.printStackTrace();
} catch (SmackException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (XMPPException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
// login
try {
Log.i(TAG, "Before xmppConnection login.....");
xmppConnection.login(hashedUserName, getPassword(), getDeviceID());
Log.i(TAG, "After xmppConnection login.....");
// return
} catch (SmackException.AlreadyLoggedInException e) {
e.printStackTrace();
} catch (SmackException.ConnectionException e) {

} catch (XMPPException e) {

} catch (Exception e) {

}
}
我收到很多这些错误。有人可以帮帮我吗。我在谷歌搜索了很多，几乎没有任何结果。我也在Smack支持社区发布了这个问题，但还没有收到任何人的回复。
PS：我已经耗尽了我可以在这里添加身体部位的行数，所以我发布了openfire服务器日志作为答案，因为我不知道如何以正确的格式包含所有内容而不会像这样打破它们。我为它道歉。答案 0 :(得分：0)

似乎客户端从未收到对'auth'节的响应。在查看smack库中的代码之后，我认为'XMPPTCPConnection.java'中'connectInternal（）'方法中的代码可能会导致此错误。我认为当connect方法仍处于握手过程中时，会调用登录，这可能会使服务器上的内容搞乱。在我们呼叫登录之前是否应该有一些延迟，直到握手过程完成？如果是这样，我该如何解决这个问题呢？如果不是那么可能导致超时错误的原因是什么？
感谢。

当您为移动客户端提供服务时，服务器端异常在生产日志中非常常见。这清楚地表明，在移动设备上，我们的网络一直在切换，它与桌面LAN / WiFi连接不同，后者不经常连接/断开连接。
所以你的具体案例似乎是一个，你可以通过我相信你已经在做的重新连接政策来控制这个。
