我正在努力解决 android 中的文件传输问题。我正在使用 smack 4.1 连接到 openfire 服务器。
我的问题是：
当我使用 Spark 到 Spark 文件传输时，它工作正常。但是当我从Spark 到 Android 或 Android 到 Android, 收到的 iq 显示错误“无法与任何提供的主机建立套接字”像这样：
<iq id="018vq-231" to="[email protected] /cdn-cgi/l/email-protection/Spark 2.6.3" from="[email protected] /cdn-cgi/l/email-protection/Smack" type="error">
<error code="-1" type="CANCEL">
<item-not-found xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/>
<text xmlns="urn:ietf:params:xml:ns:xmpp-stanzas" xml:lang="en">Could not establish socket with any provided host</text>
</error>
</iq>
我的接收代码是：
FileTransferManager fileTransferManager = FileTransferManager.getInstanceFor(xmppTcpConnection);
fileTransferManager .addFileTransferListener(new FileTransferListener() {
@Override
public void fileTransferRequest(final FileTransferRequest request) {
final IncomingFileTransfer transfer = request.accept();
File file = new File("Path/To/Save", transfer.getFileName());
transfer.recieveFile(file);
}
});
我的 ProviderManager 代码是：
我将 ServiceDiscoveryManager 和 ProviderManager 用作：
ServiceDiscoveryManager sdm = ServiceDiscoveryManager.getInstanceFor(AppConstant.xmppTcpConnection);
sdm.addFeature("http://jabber.org/protocol/disco#info");
sdm.addFeature("jabber:iq:privacy");
sdm.addFeature("jabber.org/protocol/si");
ProviderManager.addIQProvider("query",
"http://jabber.org/protocol/bytestreams", new BytestreamsProvider());
ProviderManager.addIQProvider("query",
"http://jabber.org/protocol/disco#items", new DiscoverItemsProvider());
ProviderManager.addIQProvider("query",
"http://jabber.org/protocol/disco#info", new DiscoverInfoProvider());
ProviderManager.addIQProvider("si","http://jabber.org/protocol/si",new StreamInitiationProvider());
并且，我还将谈判者注册为：
FileTransferNegotiator fileTransferNegotiator = FileTransferNegotiator.getInstanceFor(xmppTcpConnection);
我还在 Spark 调试器中注意到：当 Spark 到 Spark 传输时，会出现相同的消息，即无法与任何提供的主机建立套接字，但随后 Spark 协商流和文件被传输。
但是，在从 Spark 传输到 Android 时，从 Android 设备收到具有相同错误的 iq，并且协商是由 Spark 发起的，但我端未收到文件。
谁能指导我正确的方法。
Thanks.

发送方收到错误 IQ 后，发送方再次将 IQ 发送到接收方进行文件传输协商流，但在该 iq 之后没有从接收方收到任何 iq。
另外，我正在使用以下 smack 库：
compile 'org.igniterealtime.smack:smack-android:4.1.1'
compile 'org.igniterealtime.smack:smack-core:4.1.1'
compile 'org.igniterealtime.smack:smack-tcp:4.1.1'
compile 'org.igniterealtime.smack:smack-extensions:4.1.1'
