最近在写一个程序的过程中,遇到一个 Python 变量的变量的问题,就是某个变量的值,还是变量,然后我想取最终的值,感谢伟大的 google,写这篇文章记录下。先上代码:
#!/usr/bin/env python
#encoding=utf-8
import inspect
import ConfigParser
confPath="/home/test/config/config"
def modify_config(domain_name, app_type, port, if_api, vip, svn, svnver, yfb_ip, cron_ip, hosts, hostname, if_cas_oa, if_session, if_nginx, check_apps_dir, health_check):
if vip is None:
vip=""
if yfb_ip is None:
yfb_ip=""
if cron_ip is None:
cron_ip=""
if hosts is None:
hosts=""
if if_cas_oa is None:
if_cas_oa=""
if if_session is None:
if_session=""
# 更新指定section, option的值
conf = ConfigParser.ConfigParser()
conf.read(confPath)
### 这个 inspect.getargspec 的作用是取函数的参数列表
arg_list = inspect.getargspec(modify_config).args
### 下面的 conf.set 的第二个参数我只想取 arg 的值,而 第三个参数想取 arg 变量值的值,因为 arg 的值本身就是 modify_config 函数的参数
for arg in arg_list:
conf.set("online", arg, locals().get(arg))
conf.write(open(confPath,"w"))
if __name__ == '__main__':
domain_name = "www.test.com"
app_type = "osp"
port = "8081"
if_api = "1"
vip = "192.168.0.1"
svn = "https://svn.tools.test.com/svn/"
svnver = "24562"
yfb_ip = "192.168.0.1"
cron_ip = "192.168.0.2"
hosts = "www.test.com"
hostname = "JD-TEST-COM"
if_cas_oa = "0"
if_session = "mcs2"
if_nginx = "1"
check_apps_dir = "0"
health_check = "_health_check"
modify_config(domain_name, app_type, port, if_api, vip, svn, svnver, yfb_ip, cron_ip, hosts, hostname, if_cas_oa, if_session, if_nginx, check_apps_dir, health_check)
