Create and validate torrent seed files using the Python Open Source Library __python

The following article from the reference [1], here will be my practice process record as follows, convenient up-and reference, my operating system is Ubuntu 14.04 64bit

I. Installation of open source BT seed production software package

cd/home/taoyx/Download/

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

Once the installation is complete, use the following command to see if Mktorrent is in the following directory

Which mktorrent

/usr/local/bin/mktorrent

Two. Install the Python bencode module, which is used to obtain information about the BT seed file,

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

Three. Use the following Python script make_torrent.py to make and validate BT seed file information, and note that if you are only making and not validating, call the following command line directly in Python.

#!/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 '% ( Bt_torrent, bt_file) #validate torrent Info result = Os.popen (cmd). ReadLines () [ -1].strip () If ' do ' 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.exi T (1) else:print "The specified source can not find" sys.exit (0)

Here is the call effect graph
