我无法从公共跟踪器libtorrent下载torrent

Question

我libtorrent在python中使用模块下载torrent.我可以从私人跟踪器下载torrent,但不能从公共跟踪器下载.我尝试使用各种种子,我可以使用"传输"下载.我检查了4个不同的连接,都是一样的.

def downloadTorrent(torrent):
    """
    Download torrent using libtorrent library.
    Torrent will be stored at the current directory.
    """
    ses = lt.session()
    ses.listen_on(6881, 6891)

    info = lt.torrent_info(torrent)
    h = ses.add_torrent({'ti': info, 'save_path': './'})
    ses.start_dht()
    print 'starting', h.name()

    while (not h.is_seed()):
        s = h.status()

        state_str = ['queued', 'checking', 'downloading metadata', \
          'downloading', 'finished', 'seeding', 'allocating', 'checking fastresume']
        print '\r%.2f%% complete (down: %.1f kb/s up: %.1f kB/s peers: %d) %s' % \
          (s.progress * 100, s.download_rate / 1000, s.upload_rate / 1000, \
          s.num_peers, state_str[s.state]),
        sys.stdout.flush()

        time.sleep(1)

    print h.name(), 'complete'

当我尝试时,我得到:

0.00% complete (down: 0.0 kb/s up: 0.0 kB/s peers: 0) downloading 

它停在那里.

我不知道它是否有帮助,但私人跟踪器正在使用 http而不是udp,它不允许DHT.

您并没有真正解释如何在函数中提供 torrent 文件downloadTorrent。如果您已经将 torrent 文件下载到计算机上，您的功能就可以使用。

如果您想提供 torrent url 作为此函数的参数，您需要将 http 响应读取为字节，如下所示torrent = lt.bdecode(urllib2.urlopen(torrent_url, 'rb').read())

以下是适用于 python 2.7 的完整代码：

import libtorrent as lt
import urllib2

public_torrent = 'http://releases.ubuntu.com/14.04.3/ubuntu-14.04.3-desktop-amd64.iso.torrent'

def downloadTorrent(torrent_url):
    """
    Download torrent using libtorrent library.
    Torrent will be stored at the current directory.
    """
    ses = lt.session()
    ses.listen_on(6881, 6891)

    # read torrent file as bytes
    torrent = lt.bdecode(urllib2.urlopen(torrent_url, 'rb').read())

    info = lt.torrent_info(torrent)
    h = ses.add_torrent({'ti': info, 'save_path': './'})
    ses.start_dht()
    print 'starting', h.name()

    while (not h.is_seed()):
        s = h.status()

        state_str = ['queued', 'checking', 'downloading metadata', \
          'downloading', 'finished', 'seeding', 'allocating', 'checking fastresume']
        print '\r%.2f%% complete (down: %.1f kb/s up: %.1f kB/s peers: %d) %s' % \
          (s.progress * 100, s.download_rate / 1000, s.upload_rate / 1000, \
          s.num_peers, state_str[s.state]),
        sys.stdout.flush()

        time.sleep(1)

    print h.name(), 'complete'

downloadTorrent(public_torrent)
