【python】读取cfg/ini/txt配置文件

1.config.cfg文件内容：

 现需读取config.cfg里的host内容：

# @Time    : 2021/9/4 20:21
# @File    : readCfg.py
import os

from configparser import ConfigParser
import os

class ReadCfg():
    def __init__(self):
        pass

    def getPath(self):
        #获取当前目录
        current_dir = os.path.abspath('')
        #获取上一级目录
        filePath = os.path.dirname(current_dir)
        #再获取上一级目录
        lastFilePath = os.path.dirname(filePath)
        #拼接配置文件的路径
        cfgPath =os.path.join(lastFilePath,'conf','config.cfg')
        print(cfgPath)
        return cfgPath
    #默认获取主机的地址
    def readCfg(self,section='hostname',option = 'host'):
        #拼接配置文件的路径
        con = ConfigParser()
        con.read(self.getPath(),'utf-8')
        res = con.get(section,option)
        return res

if __name__ == '__main__':
    readCfg = ReadCfg()

2.readIni.ini

[hostname]
host = http://127.0.0.1:8088

[login]
username = test
password = 123456

读取ini文件的源码为：

# @Time    : 2021/9/4 20:21
# @Author  : '宫雪侠'
# @File    : readCfg.py
import os

from configparser import ConfigParser
import os

class Readini():
    def __init__(self):
        # 获取当前目录
        current_dir = os.path.abspath('')
        # 获取上一级目录
        filePath = os.path.dirname(current_dir)
        # 再获取上一级目录
        lastFilePath = os.path.dirname(filePath)
        # 拼接配置文件的路径
        self.iniPath = os.path.join(lastFilePath, 'conf', 'readini.ini')

    #默认获取主机的地址
    def readCfg(self,section='hostname',option = 'host'):
        #拼接配置文件的路径
        con = ConfigParser()
        con.read(self.iniPath,'utf-8')
        res = con.get(section,option)
        return res

    #默认获取主机的地址
    def getItems(self,section = 'login'):
        #拼接配置文件的路径
        con = ConfigParser()
        con.read(self.iniPath,'utf-8')
        res = con.items(section)
        return dict(res)

if __name__ == '__main__':
    readCfg = Readini().getItems()

读取txt文件源码：

# @Time    : 2021/9/6 15:23
# @Author  : '宫雪侠'
# @File    : readTxt.py
import os

class ReadTxt():
    def __init__(self):
        # 再获取上一级目录
        lastFilePath = os.path.dirname(os.path.abspath(''))
        # 拼接配置文件的路径
        self.txtPath = os.path.join(lastFilePath, 'conf', 'text.txt')
        pass
    def readAllTxt(self):
        with open(self.txtPath,'r',encoding='utf-8') as f:
            text = f.read()
            return text

    def readoneLine(self):
        with open(self.txtPath,'r',encoding='utf-8') as f:            # #读取一行
            text1 = f.readline()
            return text1

    def readLimtSize(self,size):
        with open(self.txtPath,'r',encoding='utf-8') as f:
            text1 = f.readline(size)
            return text1

    def witeTxt(self):
        with open(self.txtPath,'w',encoding='utf-8') as f:
            f.write('我是中国人')
    #追加
    def appendTxt(self):
        with open(self.txtPath,'a',encoding='utf-8') as f:
            f.write('我是中国人
')

if __name__ == '__main__':
    readTxt = ReadTxt()
    readTxt.appendTxt()
