我正在使用android进行文件传输。我使用smack 4.1连接到openfire服务器。
我的问题是： 当我使用Spark to Spark文件传输时，它工作正常。但是当我将文件从 Spark传输到Android或Android到Android 时，iq收到显示错误“无法建立套接字提供主机“像这样：
<iq id="018vq-231" to="sender@domain.com/Spark 2.6.3" from="receiver@domain.com/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：
我正在使用ServiceDiscoveryManager和ProviderManager：
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，iam还将谈判者注册为：
FileTransferNegotiator fileTransferNegotiator = FileTransferNegotiator.getInstanceFor(xmppTcpConnection);
另外我在spark调试器中注意到：当spark to spark transfer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 negotiate stream和file is transfer。
但是当从spark转移到android时，iq从android设备收到相同的错误并且协商是由spark启动的，但是我的文件没有收到。
任何人都可以以正确的方式指导我。
感谢。

在发送方收到错误IQ后，发送方再次向接收方发送IQ以进行文件传输协商流，但在此iq之后没有从接收方接收到iq。
另外，我正在使用以下smack libs：
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'
答案 0 :(得分：3)
我得到了解决方案。问题在于smack sdk。
Smack在文件传输实现中有一些错误：在我的情况下，发起者提供了字节流和ibb方法，响应者接受两种（这是错误的）方法。
（参考：@vitalyster在这里回答Getting ExecutionException on receiving file using asmack in Android）
它应该只接受一个。 因此，在创建FileNegotiator时，我只提供了一个流：
FileTransferNegotiator fileTransferNegotiator = FileTransferNegotiator.getInstanceFor(xmppTcpConnection);
FileTransferNegotiator.IBB_ONLY = true;
现在文件传输工作正常。
谢谢大家。
