无法与任何提供的主机建立套接字 [英] Could not establish socket with any provided host
问题描述
我正在为Android中的文件传输而苦苦挣扎.我正在使用smack 4.1连接到openfire服务器.
I am struggling with file transfer in android.I am using smack 4.1 to connect to openfire server.
我的问题是: 当我使用Spark到Spark进行文件传输时，它工作正常.但是，当我将文件从 Spark传输到Android或从Android传输到Android 时，iq收到显示错误提供的主机" :
My problem is: When i am using Spark to Spark file transfer, it works fine.But when i transfer file from Spark to Android or Android to Android, The iq received showing error "Could not establish socket with any provided host" like this:
<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:
My ProviderManager code is:
我将ServiceDiscoveryManager和ProviderManager用作:
I am using ServiceDiscoveryManager and ProviderManager as:
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());
and，iam还将谈判者注册为:
and , iam also registering a Negotiator as:
FileTransferNegotiator fileTransferNegotiator = FileTransferNegotiator.getInstanceFor(xmppTcpConnection);
我还在Spark调试器中指出: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，然后Spark协商流和文件.
Also i noted in spark debugger that: When spark to spark transfer, the same message occurs i.e. Could not establish socket with any provided host but then spark negotiate stream and file is transfered.
但是当从spark传输到android时，具有相同错误的iq从android设备接收到，并且协商是由spark启动的，但是在我端没有收到文件.
But while transfering from spark to android,The iq with same error received from android device and the negotiation is initiated by spark but file is not received at my end.
有人可以指导我正确的方法吗?
Can anyone please guide me the right way.
谢谢.

在发送方接收到错误IQ之后，发送方再次将IQ发送给接收方以进行文件传输协商流，但是在此iq之后没有接收方接收到iq.
此外，我正在使用以下smack库:
Also, i am using following 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'
推荐答案
我找到了解决方案.问题出在smd SDK上.
I got the solution.The problem is with smack sdk.
Smack在文件传输实现中存在一些错误:在我的情况下，启动程序提供了字节流和ibb方法，响应程序同时接受了这两种方法(这是错误的).
Smack have some bugs in file transfer implementation: in my case initiator offered bytestreams and ibb methods, responder accept both (which is wrong) methods.
(参考:@vitalyster在这里上获取ExecutionException的答案在Android中使用asmack接收文件)
(Reference: answer by @vitalyster here Getting ExecutionException on receiving file using asmack in Android )
它只能接受一个. 因此，在创建FileNegotiator时，我只提供了一个流:
It should accept only one. So while creating FileNegotiator, i offered only one stream as:
FileTransferNegotiator fileTransferNegotiator = FileTransferNegotiator.getInstanceFor(xmppTcpConnection);
FileTransferNegotiator.IBB_ONLY = true;
现在文件传输正常.
谢谢大家.
