Python实现批量转换文件编码的方法

import os
import shutil
def match(config,fullpath,type):
  flag=False
  if type == 'exclude':
    for item in config['src']['exclude']:
      if fullpath.startswith(config['src']['path']+os.path.sep+item):
        flag=True
        break
  if type=='filter':
    for item in config['src']['filter']:
      if fullpath.endswith(item):
        flag=True
        break
  return flag
def conver_file(param):
  for root, dirs, files in os.walk(param['src']['path']):
    for filename in files:
      readfile=root+os.path.sep+"%s" %filename
      print(readfile)
      if 'filter' in param['src']:
        if not (match(param,readfile,'filter')):
          continue
      s=''
      outfile=readfile.replace(param['src']['path'],param['dest']['path'])
      try :
        s=open(readfile,encoding=param['src']['encoding']).read()
      except:
        print("file %s read erro" % readfile)
        shutil.copy(readfile,outfile)
      if s: #False and
        print("save")
        with open(outfile, mode='w', encoding=param['dest']['encoding']) as a_file:
          a_file.write(s)
    for dirname in dirs:
      file=root+os.path.sep+"%s" %dirname
      if 'exclude' in param['src']:
        if(match(param,file,'exclude')):
          continue
      outdir=file.replace(param['src']['path'],param['dest']['path'])
      #print(outdir)
      if not os.path.isdir(outdir):
        os.mkdir(outdir)
if __name__ == "__main__":
  param={'src':{'path':r'D:\work\test\trunk','encoding':'gbk','exclude':['dataa'],'filter':['.php','.html','.htm']},
    'dest':{'path':"f:\\test\\new",'encoding':'utf-8'}}
  conver_file(param)
