磁力链接的BT历史
elif pt.isdir(pt.dirname(pt.absoutput = pt.abspath(output_name)path(output_name))):20世纪60年代,美国高级研究署(DARPA)提出要研制一种崭新的、能够适应现代的、生存性很强的网络,目的是对付来自print magneturi的核进攻威胁。翻看一下历史就能知道,当时把全球颗人造卫星送上了太空,美国感觉到了压力,于是他们随后也搞出了另一个足以改变未来世界的东西——ARPANET,当今互联网的雏形。
bt磁力链接 bt磁力链
如何使用python实现bt种子和磁力链接的相互转换
output_name, tor.name() + ".torrent"))相应的将BT种子转换为磁力链代码为:
import bencode, hashlib, base64, lib
torrent = open('ubuntu-12.04.2-server-amd64.iso.torrent', 'rb').read()
metadata = bencode.bdecode(torrent)
hashcontents = bencode.bencode(metadata[''])
digest = hashlib.sha1(hashcontents).digest()
b32hash = base64.b32encode(digest)
params = {'xt': 'urn:btih:%s' % b32hash,
'dn': metadata['']['name'],
'tr': metadata['announce'],
'xl': metadata['']['length']}
paramstr = lib.encode(params)
magneturi = 'magnet:?%s' % paramstr
还有另外一个效率相对较高,而且更方便的方案是安装libtorrent,在ubuntu只需要apt-get install python-libtorrent即可对应转换磁力链的代码为:
import libtorrent as b'se_path': tempdir,t
= bt.torrent_('test.torrent')
print "magnet:?xt=urn:btih:%s&dn=%s" % (._hash(), .name())
转换磁力链接为bt种子文件
下面来看一个反过程,将磁力链转化为种子文件。
1、需要先安装python-libtorrent包 ,在ubuntu环境下,可以通过以下指令完成安装:
# sudo apt-get install python-libtorrent
2、代码如下:
#!/usr/bin/env python
import shutil
import tempfile
import os.path as pt
import sys
import libtorrent as lt
from time import sleep
def magnet2torrent(magnet, output_name=None):
if output_name and \
not pt.isdir(output_name) and \
not pt.isdir(pt.dirname(pt.abspath(output_name))):
print("Invalid output folder: " + pt.dirname(pt.abspath(output_name)))
print("")
sys.exit(0)
tempdir = tempfile.mkdtemp()
ses = lt.session()
params = {
'duplicate_is_error': True,
'storage_mode': lt.storage_mode_t(2),
'paused': False,
'auto_mad': True,
'duplicate_is_error': True
}handle = lt.add_magnet_uri(ses, magnet, params)
print("Downloading Metadata (this may take a while)")
while (not handle.has_metadata()):
try:
sleep(1)
print("Aborting...")
ses.pause()
print("Cleanup dir " + tempdir)
shutil.rmtree(tempdir)
sys.exit(0)
ses.pause()
print("Done")
tor = handle.get_torrent_except KeyboardInterrupt:()
torfile = lt.create_torrent(tor)
output = pt.abspath(tor.name() + ".torrent")
if output_name:
if pt.isdir(output_name):
output = pt.abspath(pt.join(
print("Sing torrent file here : " + output + " ...")
torcontent = lt.bencode(torfile.generate())
f = open(output, "wb")
f.write(lt.bencode(torfile.generate()))
f.close()
print("Sed! Cleaning up dir: " + tempdir)
ses.remove_torrent(handle)
shutil.rmtree(tempdir)
return output
def showHelp():
print("")
print("USAGE: " + pt.basename(sys.argv[0]) + " MAGNET [OUTPUT]")
print(" MAGNET\t- the magnet ")
print(" OUTPUT\t- the output torrent file name")
print("")
def main():
if len(sys.argv) < 2:
showHelp()
sys.exit(0)
magnet = sys.argv[1]
output_name = None
if len(sys.argv) >= 3:
output_name = sys.argv[2]
magnet2torrent(magnet, output_name)
if __name__ == "__main__":
main()
3、用法如下
# python Magnet_To_Torrent2.py
