如果你想用 python 编写你的客户端,在 linux 上,安装它:

If you want to write your client in python, on linux, install it with:

sudo apt-get install python-libtorrent

一个非常简单的python代码示例,用它来下载种子:

A very simple example of python code to use it to download a torrent:

import libtorrent as lt
import time
import sys

ses = lt.session({'listen_interfaces': '0.0.0.0:6881'})

info = lt.torrent_info(sys.argv[1])
h = ses.add_torrent({'ti': info, 'save_path': '.'})
s = h.status()
print('starting', s.name)

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

    print('
%.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, s.state), end=' ')

    alerts = ses.pop_alerts()
    for a in alerts:
        if a.category() & lt.alert.category_t.error_notification:
            print(a)

    sys.stdout.flush()

    time.sleep(1)

print(h.status().name, 'complete')
