下面的文章来源于参考文献[1], 这里将我的实践过程记录如下,方便后来人参考,我的操作系统是Ubuntu 14.04 64bit
一.安装开源BT种子制作软件包
cd /home/taoyx/下载/
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
安装完成后,使用下面的命令查看mktorrent是否在下面的目录中
which mktorrent
/usr/local/bin/mktorrent
二.安装python的bencode模块,以便用来获取BT种子文件信息,
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脚本make_torrent.py来制作和验证BT种子文件信息, 注意,如果只制作而不验证, 直接在python中调用下面的命令行就可以了.
#!/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)下面是调用效果图
