Android Smack4.1.1 XMPP 文件传输问题与 Iphone

Question

我们在新的 android 4.1.1 中实现了 FileTransfer 功能。 除了将文件传输到 iphone 客户端外，一切正常。协商时传输失败。

当使用 windows smack 客户端传输成功时，我们会收到以下日志。

当使用 iphone smack 客户端传输不成功时，我们会收到以下日志：

通过比较日志，我觉得这是为 xmpp 登录连接设置错误代理的问题。

XMPP 登录代码：

ProxyInfo proxy = new ProxyInfo(null, loc_IP, 7777, null,null);

我真的很想这样用，

ProxyInfo proxy = new ProxyInfo(ProxyType.SOCKS5, loc_IP, 7777, null,null);

，但随后登录过程失败。

= XMPPTCPConnectionConfiguration.builder()
    .setProxyInfo(proxy)
    .setServiceName(loc_IP)
    .setHost(loc_IP)
    .setPort(XMPP_PORT)
    .setCompressionEnabled(false)
    .setDebuggerEnabled(true)
    .setCustomSSLContext(sslContext)
    .setSecurityMode(SecurityMode.ifpossible)
    .setHostnameVerifier(verifier)
    .setUsernameAndPassword(username, pwd)
    .setResource(resourcestring)
    .build();

文件传输启用服务代码：

    ServiceDiscoveryManager sdm=ServiceDiscoveryManager.getInstanceFor(main.login.connection);

    if (sdm == null) {
     sdm = ServiceDiscoveryManager.getInstanceFor(main.login.connection);
     sdm.addFeature("http://jabber.org/protocol/disco#info");
     sdm.addFeature("jabber:iq:privacy");
     sdm.removeFeature("http://jabber.org/protocol/ibb");
    }
		
    SmackConfiguration.DEBUG  = true;
		
    //   FileTransfer Service
        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());

 
    fileTransferNegotiator =     FileTransferNegotiator.getInstanceFor(main.login.connection);
    fileTransferNegotiator.IBB_ONLY = false;

    fileTransferManager = FileTransferManager.getInstanceFor(main.login.connection);
    fileTransferManager.addFileTransferListener(fileTransferListener);

    fileTransferListener =new FileTransferListener() {

    @Override
     public void fileTransferRequest(FileTransferRequest request) {

	     IncomingFileTransfer inComingFileTransfer = request.accept();
     //followed by status handling code in a thread
				}
			};

以下设置帮助我实现了一对一的文件传输：

我们需要创建一个基于 Socks5 的文件传输监听器，这个问题发生在 iphone 和 android 之间进行文件传输时。

1) 由于文件传输是通过 WIFI 进行的，Android 包含所有类型的 ip：ipV4 + ipv6（如果在设备中可用），因此我们需要去除任何 ipv6 类型地址的默认代理设置或空白 0.0。 0.0 类型地址。 2）我们没有正确实现代理，需要实现socks5代理设置。

最后，这些是连接配置上的设置。

//XMPP Connection Setup
connConfig = XMPPTCPConnectionConfiguration
  .builder()
  .setServiceName(loc_IP)
  .setHost(loc_IP)
  .setPort(XMPP_PORT)
  .setCompressionEnabled(false)
  .setDebuggerEnabled(true)
  .setCustomSSLContext(sslContext)
  .setSecurityMode(SecurityMode.disabled)
  .setHostnameVerifier(verifier)
  .setUsernameAndPassword(nick_Name, password)
  .setResource(resourcestring)
  .build();

SmackConfiguration.setDefaultPacketReplyTimeout(50000);
Socks5Proxy.setLocalSocks5ProxyEnabled(false);
Socks5Proxy.setLocalSocks5ProxyPort(7777);

removeAbnormalIP();

SASLPlainMechanism saslPlainMechanism = new SASLPlainMechanism();
SASLAuthentication.registerSASLMechanism(saslPlainMechanism);


CXmppFileTransferManager xmppFileManager = main.getXMPPTransferManager();
xmppFileManager.serviceEnabledForXmppFileTransfer();

private void removeAbnormalIP() {

WifiManager wifiManager = (WifiManager) main.currentContext.getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();

Socks5Proxy mProxy = Socks5Proxy.getSocks5Proxy();
List<String> addresses = new ArrayList<String>();

if (wifiInfo != null) {
	int ipAddress = wifiInfo.getIpAddress();
	String strIPAddess = ((ipAddress >> 0) & 0xFF) + "."
			+ ((ipAddress >> 8) & 0xFF) + "."
			+ ((ipAddress >> 16) & 0xFF) + "."
			+ ((ipAddress >> 24) & 0xFF);

	// ignore "0.0.0.0"
	if (!strIPAddess.equals("0.0.0.0"))
		addresses.add(strIPAddess);

}
// set an ip in case there is a Wifi Connection
// otherwise addresses will be empty and local S5B proxy will not be
// used
mProxy.replaceLocalAddresses(addresses);
