java中的Torrent解析器

Question

java中是否有可用的torrent解析器从.torrent文件中提取元数据...

Answer 1

An article on wiki.theory covering the bitorrent spec led to BDecoder , a decoder for the fileformat used by torrent to encode metadata. Have fun! (The page contains a link to a corresponding encoder too)

The easiest approach should be using the Bittorrent API . The provided lib contains a client, which should be capable of decoding metadata and include the java classes for that purpose.

Answer 2

Have a look at jtorrentparser

It parses an Array of shorts with the static parse() method:

TorrentParser.parse(short[]);

Answer 3

You can use this spec to write up a parser yourself. It shouldn't be too difficult.

Otherwise you could check out the source for any Java-based client. Azureus/Vuze has their source available (don't see any information regarding license at first look).
