Python讀取ini配置文件

需求：

寫個項目，用到數據庫，多個地方使用，不能硬編碼。很類似java的properties文件

Python支持ini文件的讀取

涉及模塊：

ConfigParser

xml文件

1. db_config.ini
2. [baseconf]
3. host=127.0.0.1
4. port=3306
5. user=root
6. password=root
7. db_name=evaluting_sys
8. [concurrent]
9. processor=20

對應的python代碼

1. #!/usr/bin/python
2. # -*- coding:utf-8 -*-
3. #author: lingyue.wkl
4. #desc: use to db ops
5. #---------------------

9. import sys,os
10. import ConfigParser
12. class Db_Connector:
13. def __init__(self, config_file_path):
14. cf = ConfigParser.ConfigParser()
15. cf.read(config_file_path)
17. s = cf.sections()
18. print 'section:', s
20. o = cf.options("baseconf")
21. print 'options:', o
23. v = cf.items("baseconf")
24. print 'db:', v
26. db_host = cf.get("baseconf", "host")
27. db_port = cf.getint("baseconf", "port")
28. db_user = cf.get("baseconf", "user")
29. db_pwd = cf.get("baseconf", "password")
31. print db_host, db_port, db_user, db_pwd
33. cf.set("baseconf", "db_pass", "123456")
34. cf.write(open("config_file_path", "w"))
35. if __name__ == "__main__":
36. f = Db_Connector("../conf/db_config.ini")

得到結果：

section: ['concurrent', 'baseconf']
options: ['host', 'db_name', 'user', 'password', 'port']
db: [('host', '127.0.0.1'), ('db_name', 'evaluting_sys'), ('user', 'root'), ('password', 'root'), ('port', '3306')]
127.0.0.1 3306 root root
