python中使用configparser库，实现配置文件的读取

 1 from configparser import ConfigParser

 3 class DoConfig:
 4     def __init__(self,filepath,encoding='utf-8'):
 5         self.cf = ConfigParser()
 6         self.cf.read(filepath,encoding)

10         return self.cf.sections()

12     #获取某一section下的所有option
13     def get_option(self,section):
14         return self.cf.options(section)
15 
16     #获取section、option下的某一项值-str值
17     def get_strValue(self,section,option):
18         return self.cf.get(section,option)
19 
20     # 获取section、option下的某一项值-int值
21     def get_intValue(self,option):
22         return self.cf.getint(section,option)

28     # 获取section、option下的某一项值-bool值
29     def get_boolValue(self,option):
30         return self.cf.getboolean(section,option)
31 
32     def setdata(self,option,value):
33         return self.cf.set(section,value)
34 
35 if __name__ == '__main__':
36     cf = DoConfig('demo.conf')
37     res = cf.get_sections()
38     print(res)
