Python处理MLDonkey 下载中文文件乱码问题

python文件内容如下：

# -*- coding: cp936 -*-

import os ,string ,urllib ,operator

# 文件替换目录路径

sdir='/usr/local/mldonkey/incoming/'

# 数字标记

sNum='0123456789'

# 遍历目录做文件名转换

def convert():

filenames=os.listdir(sdir)

for filename in filenames :

if filename != convertName(filename) :

print filename + ' >>> ' + convertName(filename)

os.rename(sdir + filename ,sdir + convertName(filename))

# 转换一个文件名

def convertName(s) :

location = 0

ret = ""

while True :

if location + 8 <= len(s) :

subStr = s[location:location + 8]

if check(subStr) :

ret += "%" + hex((int)(subStr[1:4]))[2:4] + "%" + hex((int)(subStr[5:8]))[2:4]

location = location + 8

else :

ret += s[location :location + 1]

location = location + 1

else :

ret += s[location:]

break

return urllib.unquote(ret)

# 检查一个字符串是否需要做转换

def check(s):

if len(s) != 8 :

return False

if s[0] != '_' or s[4] != '_' :

return False

if (s[1] in sNum) and (s[2] in sNum) and (s[3] in sNum) and (s[5] in sNum) and (s[6] in sNum) and (s[7] in sNum) :

return True

return False

# 执行文件名转换

convert()

要运行此脚步，需要Python2.4，在命令行输入：
python mldonkey.py
运行即可。
