Python脚本解析BitTorrent种子文件内容

有很多种子文件，有时候记不清里面都是什么东西，又不想一个一个的拖放到迅雷或BT软件里头看，

上网查了一下Python的脚本，自己也稍微修改了一下，代码如下，粘贴到文本编辑器中：

保存成py后缀的，直接运行

import re def tokenize(text, match=re.compile("([idel])|(/d+):|(-?/d+)").match): i = 0 while i < len(text): m = match(text, i) s = m.group(m.lastindex) i = m.end() if m.lastindex == 2: yield "s" yield text[i:i+int(s)] i = i + int(s) else: yield s def decode_item(next, token): if token == "i": # integer: "i" value "e" data = int(next()) if next() != "e": raise ValueError elif token == "s": # string: "s" value (virtual tokens) data = next() elif token == "l" or token == "d": # container: "l" (or "d") values "e" data = [] tok = next() while tok != "e": data.append(decode_item(next, tok)) tok = next() if token == "d": data = dict(zip(data[0::2], data[1::2])) else: raise ValueError return data def decode(text): try: src = tokenize(text) data = decode_item(src.next, src.next()) for token in src: # look for more tokens raise SyntaxError("trailing junk") except (AttributeError, ValueError, StopIteration): raise SyntaxError("syntax error") return data if __name__ == "__main__": #需要读取的文件名称放到这里 data = open("Riko.Tachibana.torrent", "rb").read() torrent = decode(data) myfile = file("testit.txt", 'w') a = u'文件名称'.encode('gbk') b = u'文件大小'.encode('gbk') print "%s /t %s /n" % (a,b) for file in torrent["info"]["files"]: print "%s /t %d Mb " % ("/".join(file["path"]), file["length"]/1024/1024) print "-----------------------------------------------------------------"

注意要保存成Utf-8格式的文件，不能使用ASCII编码格式保存，否则中文会乱码或无法编译
