Python处理MLDonkey 下载中文文件乱码问题 (2)

上次写了一篇关于mldonkey转码的东西，最近作了一次修改，不过仍然需要Python2.4版本的支持，代码如下：

mldonkey.py

# -*- coding: cp936 -*- ############################################################ # convert mldonkey's chinese # Version: 0.1 # Author: kongxx # Email: [email protected] ############################################################ import os ,sys ,string ,urllib ,telnetlib ,operator # define the mldonkey incoming dir sdir='/usr/local/mldonkey/incoming/' #flag the num sNum='0123456789' #length len8 = 8 len12 = 12 lengths = [len8 ,len12] def convert(): filenames=os.listdir(sdir) for filename in filenames : for length in lengths : s1 = filename s2 = convertName(filename ,length) try : if s1 != s2 : print '############################################################' print 'The source name is:' + s1 print 'The target name is:' + s2 print '' confirm = raw_input('Do you confirm rename the file[yes or no]? ') if confirm == 'yes' : os.rename(sdir + s1 ,sdir + s2) break except UnicodeDecodeError: print '' # convert ths file name # param s the filename # param length def convertName(s ,length) : location = 0 ret = '' if length not in lengths: return s while True : if location + length <= len(s) : subStr = s[location:location + length] if check(subStr) : if length == len8 : ret += "%" + hex((int)(subStr[1:4]))[2:4] + "%" + hex((int)(subStr[5:8]))[2:4] if length == len12 : ret += "%" + hex((int)(subStr[1:4]))[2:4] + "%" + hex((int)(subStr[5:8]))[2:4] + "%" + hex((int)(subStr[9:12]))[2:4] location = location + length else : ret += s[location :location + 1] location = location + 1 else : ret += s[location:] break ret = urllib.unquote(ret) if ret == s : return s try : if length == len8 : return ret.decode('GBK') if length == len12 : return ret.decode('UTF-8') except UnicodeDecodeError: return ret def check(s): if len(s) != len8 and len(s) != len12: return False if s[0] != '_' or s[4] != '_' : return False if len(s) == len12 and s[8] != '_': return False s = s.replace('_','') for c in s : if (c not in sNum) :return False return True convert()

在命令行输入python mldonkey.py即可以转换。
