20160520update: 最省事的还是读JSON
#=====================================
发现python读写配置文件比较方便。
import ConfigParser
接口:ConfigParser.ConfigParser()
读写文件:read write
结构: config file =>sections=>options=>items
读取某个option的值(str): get(section,option)
1) 基本的读取配置文件
-read(filename) 直接读取ini文件内容
-sections() 得到所有的section,并以列表的形式返回
-options(section) 得到该section的所有option
-items(section) 得到该section的所有键值对
-get(section,option) 得到section中option的值,返回为string类型
-getint(section,option) 得到section中option的值,返回为int类型,还有相应的getboolean()和getfloat() 函数。
2.基本的写入配置文件
-add_section(section) 添加一个新的section
-set( section, option, value) 对section中的option进行设置,需要调用write将内容写入配置文件。
程序如下:
#/usr/bin/python
import ConfigParser
import string, os, sys
cf = ConfigParser.ConfigParser()
cf.read("test.conf")
#return all section
secs = cf.sections()
print 'sections:', secs
opts = cf.options("db")
print 'options:', opts
kvs = cf.items("db")
print 'db:', kvs
#read by type
db_host = cf.get("db", "db_host")
db_port = cf.getint("db", "db_port")
db_user = cf.get("db", "db_user")
db_pass = cf.get("db", "db_pass")
#read int
threads = cf.getint("concurrent", "thread")
processors = cf.getint("concurrent", "processor")
print "db_host:", db_host
print "db_port:", db_port
print "db_user:", db_user
print "db_pass:", db_pass
print "thread:", threads
print "processor:", processors
#modify one value and write to file
cf.set("db", "db_pass", "xgmtest")
cf.write(open("test.conf", "w"))
