需要先安裝bencode.py庫。
pip install bencode.py
import bencode
import hashlib
from urllib.parse import quote
def torrent_file_to_magnet(torrent_file):
data = open(torrent_file, 'rb').read()
metadata = bencode.bdecode(data)
name = metadata['info']['name']
dn = quote(name)
info_bts = bencode.bencode(metadata['info'])
info_hash = hashlib.sha1(info_bts).hexdigest()
return f'magnet:?xt=urn:btih:{info_hash}&dn={dn}'
if __name__ == '__main__':
print(torrent_file_to_magnet('ubuntu-20.04-desktop-amd64.iso.torrent'))
輸出:
magnet:?xt=urn:btih:9fc20b9e98ea98b4a35e6223041a5ef94ea27809&dn=ubuntu-20.04-desktop-amd64.iso
