python -config-ini 配置文件的使用

python使用自带的configparser模块用来读取配置文件，配置文件的形式类似windows中的ini文件

在使用前需要先安装该模块，使用pip安装即可

2.configparser读取文件的基本方法

依赖： pip install  configparser

中文乱码问题:  j解决

 conf.read(path,encoding="utf-8")

config.ini

[test]
test = myttwar
rndis = 0
aaa = 0
[kafka]
host = 192.168.25.147:9092

ConfigUtils.py:(推荐使用)

    # 使用介绍
# cf=ConfigUtils('../../config.ini') #加载配置文件 config.ini
# cf.getValue('kafka','host') #  读取某个域下的key值
# cf.getValue('test','test1','1000')  #设置某个域下的key所对应的value值，这里最好设置字符串不然再读会报错，具体原因没探究
# for k in cf.options('milestoneCode'):   #获取某个域下的所有key
#     print( k)
# cf.reset('test')    #重置某个域下所有key的value为0

方式2：直接定义方法：
