python将ansible配置转为json格式实例代码

[webserver]
192.168.204.70
192.168.204.71

[dbserver]
192.168.204.72
192.168.204.73
192.168.204.75

[proxy]
192.168.204.76
192.168.204.77
192.168.204.78

[test]
192.168.204.79
192.168.204.80

[haproxy]
192.168.205.82
192.168.204.83

 用python将ansible配置转为json格式，python代码如下：

import ConfigParser
import json

dict_result = {}
cf = ConfigParser.ConfigParser(allow_no_value=True)
cf.read('/etc/ansible/hosts.test')

secs = cf.sections()

for sec in secs:
 dict_result[sec] = cf.options(sec)
print json.dumps(dict_result)

转换结果如下(python版本使用2.7版本的)：

/usr/local/python/bin/python /tmp/test.py
{"test": ["192.168.204.79", "192.168.204.80"], "haproxy": ["192.168.205.82", "192.168.204.83"], "webserver": ["192.168.204.70", "192.168.204.71"], "proxy": ["192.168.204.76", "192.168.204.77", "192.168.204.78"], "dbserver": ["192.168.204.72", "192.168.204.73", "192.168.204.75"]}

 转换成json文件就方便在前端进行展示了，使用Flask提供json格式的接口如下：

#获取ansible分组
@app.route('/web_test/ansible')

def web_test_ansible():
  dict_result = {}
  cf = ConfigParser.ConfigParser(allow_no_value=True)
  cf.read('/etc/ansible/hosts.test')

  secs = cf.sections()
  for sec in secs:
    dict_result[sec] = cf.options(sec)
  return json.dumps(dict_result)
