用法:
在python中…
importyabencode# bencode supports dicts, lists, ints and strings (bytestrings)yabencode.encode({'foo':'baz','list':['eggs','spam','bacon']})# Input can be string, bytes or a file objectyabencode.decode(b'd3:foo3:baz4:listl4:eggs4:spam5:baconee')try:# Malformed data, 'spam' is missing an 'a'yabencode.decode(b'd3:foo3:baz4:listl4:eggs4:spm5:baconee')exceptyabencode.MalformedBencodeExceptionase:print(e)# Unexpected data type (b':') at position 31 (0x1F hex)try:# Bencode does not support floatsyabencode.encode({'float':3.14})exceptyabencode.BencodeExceptionase:print(e)# Unsupported type <class 'float'>
或者使用命令行工具:
$ yabencode -h usage: yabencode [-h][-t KEY][-r] FILE Bdecode a file/standard input and pretty-print the resulting data positional arguments: FILE Input file. Use - for stdin optional arguments: -h, --help show this help message and exit -t KEY, --truncate KEY Truncate values under given key. May be repeated for multiple values -r, --raw Raw keys - do not decode dictionary keys $ # The 'pieces'-bytestring is rather long, so let's truncate it $ yabencode -t pieces ubuntu-17.04-desktop-amd64.iso.torrent {'announce': b'http://torrent.ubuntu.com:6969/announce', 'announce-list': [[b'http://torrent.ubuntu.com:6969/announce'], [b'http://ipv6.torrent.ubuntu.com:6969/announce']], 'comment': b'Ubuntu CD releases.ubuntu.com', 'creation date': 1492077159, 'info': {'length': 1609039872, 'name': b'ubuntu-17.04-desktop-amd64.iso', 'piece length': 524288, 'pieces': '<truncated>'}} $ # Reading bytes from stdin (using -r to not decode the keys) $ curl -s 'http://torrent.ubuntu.com:6969/scrape?info_hash=%59%06%67%69%b9%ad%42%da%2e%50%86%11%c3%3d%7c%44%80%b3%85%7b'| yabencode -r - {b'files': {b'Y\x06gi\xb9\xadB\xda.P\x86\x11\xc3=|D\x80\xb3\x85{': {b'complete': 3473, b'downloaded': 33029, b'incomplete': 102, b'name': b'ubuntu-17.04-desktop-amd64.iso'}}}
