下面的文章來源於參考文獻[1], 這裡將我的實踐過程記錄如下,方便後來人參考,我的作業系統是Ubuntu 14.04 64bit

一.安裝開源BT種子製作軟體包

cd  /home/taoyx/下載/

wget http://jaist.dl.sourceforge.net/project/mktorrent/mktorrent/1.0/mktorrent-1.0.tar.gz

tar zxvf mktorrent-1.0.tar.gz

cd mktorrent-1.0

make

sudo make install

安裝完成後,使用下面的命令檢視mktorrent是否在下面的目錄中

which mktorrent

/usr/local/bin/mktorrent

二.安裝python的bencode模組,以便用來獲取BT種子檔案資訊,

wget https://pypi.python.org/packages/source/b/bencode/bencode-1.0.tar.gz

tar zxvf bencode-1.0.tar.gz

cd bencode-1.0.tar.gz

sudo python setup.py install

三.利用下面的python指令碼make_torrent.py來製作和驗證BT種子檔案資訊, 注意,如果只製作而不驗證, 直接在python中呼叫下面的命令列就可以了.

#!/usr/bin/env python
#encoding: utf-8

import os, re, time, sys
import hashlib, bencode

if len(sys.argv) != 3:
    print 'usage: %s <src_file> <dst_file>' % sys.argv[0]
    sys.exit(1)

bt_file = sys.argv[1]
bt_torrent = sys.argv[2]

if os.path.exists(bt_torrent):
    os.remove(bt_torrent)

if os.path.exists(bt_file):
    #make torrent ......
    cmd = '/usr/local/bin/mktorrent -v -p -l 18 -a http://bt1.text.cn/announce -a http://bt2.text.cn/announce -o %s %s' \
    % (bt_torrent, bt_file)
    #validate torrent info
    result = os.popen(cmd).readlines()[-1].strip()
    if 'done' in result:
        bt_path = {}
        bt_filename = open(bt_torrent, 'rb')
        bt_info = bencode.bdecode(bt_filename.read()).get('info')
        bt_info_hash_hex = hashlib.sha1(bencode.bencode(bt_info)).hexdigest()
        if os.path.isdir(bt_file):
            bt_file_size = 0
            for length in bt_info.get('files'):
                bt_file_size += int(length['length'])
                bt_path['/'.join(length['path'])] = length['length']
        else:
            bt_file_size = bt_info.get('length')
            bt_file_name = bt_info.get('name')
            bt_path[bt_file_name] = bt_file_size
        bt_filename.close()
        print bt_path
        print "Create torrent success"
    else:
        print "Create torrent fail"
        sys.exit(1)
else:
    print "The specified source can not find"
    sys.exit(0)
