python 的 ConfigParser 模块

来源：互联网发布：spring源码深度解析编辑：程序博客网时间：2024/05/21 06:49

configParser 模块用于操作特定格式的配置文件，该类配置文件可以包含一个或多个节（section），每个节可以有多个参数（键=值）。

样例配置文件（/home/colben/git/python/conf/example_conf）

[book]  title:ConfigParser模块教程  author:大头爸爸  email:366500050@qq.com  time:2012-09-20 22:04:55    [size]  size:1024    [other]  blog:csdn.net

上面配置文件中用的是冒号，也可以用等号。

example.py文件

# -*- coding: utf-8 -*-  import ConfigParser  import string  config=ConfigParser.ConfigParser()  config.read(u'/home/colben/git/python/conf/example_conf')  print string.upper(config.get("book","title")),  print "by",config.get("book","author"),  print "("+config.get("book","email")+")"  print  print config.get("size","size")  print  print config.sections()    for section in config.sections():      print section      for option in config.options(section):          print " ",option,"=",config.get(section,option)

example.py文件执行结果

CONFIGPARSER模块教程 by 大头爸爸 (366500050@qq.com)    1024    ['book', 'size', 'other']  book    title = ConfigParser模块教程    author = 大头爸爸    email = 366500050@qq.com    time = 2012-09-20 22:04:55  size    size = 1024  other    blog = csdn.n

写入配置文件实例

import ConfigParser  import sys  config=ConfigParser.ConfigParser()  config.add_section("book")  config.set("book","title","这是标题")  config.set("book","author","大头爸爸")  config.add_section("size")  config.set("size","size",1024)  config.write(sys.stdout)

执行结果

[book]  title = 这是标题  author = 大头爸爸    [size]  size = 1024

ConfigParser方法

#1、创建ConfigParser实例  config=ConfigParser.ConfigParser()    #2、返回配置文件中节序列  config.sections()    #3、返回某个项目中的所有键的序列  config.options(section)    #4、返回section节中，option的键值  config.get(section,option)    #5、添加一个配置文件节点(str)  config.add_section(str)    #6、设置section节点中，键名为option的值(val)  config.set(section,option,val)    #7、读取配置文件  config.read(filename)    #8、写入配置文件  config.write(obj_file)

综合实例

#coding=utf-8    import ConfigParser    def writeConfig(filename):      config = ConfigParser.ConfigParser()      # set db      section_name = 'db'      config.add_section( section_name )      config.set( section_name, 'dbname', 'MySQL')      config.set( section_name, 'host', '127.0.0.1')      config.set( section_name, 'port', '80')      config.set( section_name, 'password', '123456')      config.set( section_name, 'databasename', 'test')        # set app      section_name = 'app'      config.add_section( section_name )      config.set( section_name, 'loggerapp', '192.168.20.2')      config.set( section_name, 'reportapp', '192.168.20.3')        # write to file      config.write( open(filename, 'a') )    def updateConfig(filename, section, **keyv):      config = ConfigParser.ConfigParser()      config.read(filename)      print config.sections()      for section in config.sections():          print "[",section,"]"          items = config.items(section)          for item in items:              print "\t",item[0]," = ",item[1]      print config.has_option("dbname", "MySQL")      print config.set("db", "dbname", "11")      print "..............."      for key in keyv:          print "\t",key," = ", keyv[key]      config.write( open(filename, 'r+') )    if __name__ == '__main__':      file_name = 'test.ini'      writeConfig(file_name)      updateConfig(file_name, 'app', reportapp = '192.168.100.100')      print "end__"
