java - 无法使用 Beem-Asmack 在 XMPP FileTransfer 中处理上传

转载作者：太空狗更新时间：2023-10-29 14:27:39

我在处理从“Android 聊天”到其他客户端(如 Pidgin)的文件传输时遇到问题:Pidgin 客户端收到传输请求，但我的应用程序无法开始传输文件。

我必须说我已经阅读了所有 stackoverflows 问题，一些 http://community.igniterealtime.org/线程，但所有这些都没有解决我的问题。

为了测试，我在端口 5222 上使用 jabber.org 服务器，并且我使用 Beem-Asmack 库 v7(在某些客户端中，您还必须指定代理:这是必要的吗？？)。文件传输代码如下:

public boolean sendFile(final String jid, final String path, String description) {
    ServiceDiscoveryManager sdm = ServiceDiscoveryManager.getInstanceFor(this.xmpp);
    /*if (sdm==null) {
        sdm = new ServiceDiscoveryManager(this.xmpp);*/
        sdm.addFeature("http://jabber.org/protocol/disco#info");
        sdm.addFeature("http://jabber.org/protocol/disco#item");
        sdm.addFeature("jabber:iq:privacy");
    //}

    Log.d("sending file", "maganer");
    FileTransferNegotiator.setServiceEnabled(this.xmpp, true);
    FileTransferManager manage = new FileTransferManager(this.xmpp);
    Log.d("sending file", "set true");

    OutgoingFileTransfer.setResponseTimeout(10000);
    OutgoingFileTransfer oft = manage.createOutgoingFileTransfer(this.myRoster.getPresence(jid).getFrom());
    try {
        Log.d("sending file", "try to send... " + path);
        oft.sendFile(new File(path), description);
        Log.d("sending file", "Accepted");
        while (!oft.isDone()) {
            Log.d("status", oft.getStatus().toString());
            Log.d("percent", new Long(oft.getBytesSent()).toString());
            if (oft.getStatus() == FileTransfer.Status.error) {
                Log.e("percent", "Error " + new Long(oft.getBytesSent()).toString() + " " + oft.getError() + " " + oft.getException());
                oft.cancel();
                return false;
            }
            //Thread.sleep(1000);
        }
    } catch (Throwable e) {
        e.printStackTrace();
        Log.e("sendFile", path);
        return false;
    }
    return true;
}

现在我将描述我的错误:从日志记录中，我收到 -1 作为“百分比”和“协商流”作为“状态”。我不知道我错在哪里以及如何开始传输。感谢您的任何意见或建议。

编辑 (2)现在我已经通过添加部分解决了我的问题

FileTransferNegotiator.IBB_ONLY = true;

在初始化 FileTransferManager 和重新安排 ServiceDiscoveryManager 初始化之前，如下所示:

ServiceDiscoveryManager sdm = ServiceDiscoveryManager.getInstanceFor(this.xmpp);
     if (sdm==null)
         sdm = new ServiceDiscoveryManager(this.xmpp);
     sdm.addFeature("http://jabber.org/protocol/disco#info");
     sdm.addFeature("http://jabber.org/protocol/disco#item");
     sdm.addFeature("jabber:iq:privacy");

我还在启动时添加了以下配置:

SmackConfiguration.setPacketReplyTimeout(15000);

顺便说一句，现在我达到了与原始文件相同数量的进度值，但文件没有在接收方关闭。因此，会引发超时并中止传输。我如何传达文件的最终确定？似乎我传输了整个文件，即使其他客户端 (Pidgin) 不处理它。再次感谢。

最佳答案

public void send()
{

    configureProviderManager(connection);
    FileTransferNegotiator.IBB_ONLY = true;
    FileTransferNegotiator.setServiceEnabled(connection, true);
    FileTransferManager manager = new FileTransferManager(connection);
    //OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer("hariom@jabber.ccc.de/Smack");
    String to = connection.getRoster().getPresence("hariom@jabber.ccc.de").getFrom();
    OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer(to);


    File file = new File("/sdcard/DCIM/Camera/1385869353956.jpg");
    try {
        Log.d("file sending",file.getAbsolutePath()+" "+file.getName());
        configureProviderManager(connection);
       transfer.sendFile(file, "test_file");
    } catch (XMPPException e) {
       e.printStackTrace();
    }

    while(!transfer.isDone()) {
        Log.d("status", transfer.getStatus().toString());
        Log.d("percent", new Long(transfer.getBytesSent()).toString());
        if (transfer.getStatus() == Status.error) {
            Log.e("percent", "Error " + new Long(transfer.getBytesSent()).toString() + " " + transfer.getError() + " " + transfer.getException());
            transfer.cancel();

        }

        if(transfer.getStatus().equals(Status.refused))
                 System.out.println("refused  " + transfer.getError());
        else if( transfer.getStatus().equals(Status.error))
             System.out.println(" error " + transfer.getError());
        else if(transfer.getStatus().equals(Status.cancelled))
           System.out.println(" cancelled  " + transfer.getError());
        else
           System.out.println("Success");
