python结合re过滤敏感词
越来越觉得Python可爱了，最近写一个过滤敏感词的类，因为好多地方需要用。于是查了一些资料。发现实现代码挺简单的，在这里记录一下。import re
from Common.CommonSingleton import CSingleton
class CSensitiveFilter(CSingleton):
#初始化类
def __init__(self):
self.filename='word.dat'
self.strPatton='(';
self.readFlag = False;
self.pattern='';
self.readFilterPatten();
def init(self):
if self.readFlag == False:
self.readFilterPatten();
#读取敏感词文件，构造过滤pattern
def readFilterPatten(self):
file = open(self.filename)
for eachline in file:
self.strPatton=self.strPatton+eachline.replace('\n','')+'|';
self.strPatton=self.strPatton[:-1]+")"
file.close();
self.readFlag=True;
self.pattern = re.compile(self.strPatton)
#敏感词过滤
def filter(self,message):
return self.pattern.sub('*',message)
#判断是否有敏感字
def judgeSpecialSign(self,message):
match = self.pattern.match(message.strip());
if match == None:
return True;
return False;
