无法与任何提供的主机建立套接字

Could not establish socket with any provided host

我正在努力处理 android.I 中的文件传输,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,当我将文件从 Spark 传输到 Android 或从 Android 传输到 Android[=47= 时,它工作 fine.But ], 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,我还注册了一个 Negotiator 作为:

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 协商流和文件是已转移。

但是从 spark 传输到 android 时,从 android 设备接收到具有相同错误的 iq 并且协商由 spark 发起但我端未收到文件。

谁能指导我正确的方法。

谢谢。

sender端收到error IQ后,sender再次向receiver发送IQ文件传输协商流,但此iq后没有收到receiver端的iq

此外,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'

我得到 solution.The 问题是 smack sdk。

Smack 在文件传输实现中有一些错误:在我的例子中,发起者提供字节流和 ibb 方法,响应者接受这两种(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
