大佬教程收集整理的这篇文章主要介绍了python将ansible配置转为json格式实例代码，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

python将ansible配置转为json格式实例代码

ansible的配置文件举例如下，这种配置文件不利于在前端的展现，因此，我们用一段简单的代码将ansible的配置文件转为json格式的：

[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)

然后前端代码(使用bootstrap treeview)如下：

<script src="/static/js/bootstrap-treeview.js"></script>
  <script type="text/javascript">
    $(document).ready(function () {

      $('#btn-get-hostgroup').click(function () {
        getAll@R_772_10943@k = $('#hostgrouptree').treeview('get@R_772_10943@ked');
        for (var i = 0; i < getAll@R_772_10943@k.length; i++) {
          console.log(getAll@R_772_10943@k[i].text);
        }
      });


      $.ajax({
        url: '/web_test/ansible',type: 'GET',success: function (data) {
          result = JSON.parse(data);
          nodes = [];
          for (var hostgroup in result) {
            var nodeshostgroup = [];
            hosts = result[hostgroup];
            for (var i = 0; i < hosts.length; i++) {
              nodeshostgroup.push({text: hosts[i],SELEctable:falsE});
            }
            nodes.push({text: hostgroup,nodes: nodeshostgroup,SELEctable:falsE});
          }
          $('#hostgrouptree').treeview({data: [{text: 'all',nodes: nodes,SELEctable:falsE}],show@R_772_10943@kbox: true,showBorder:falsE});
        }
      });
    });
  </script>
{% endblock %}
{% block page_content %}

  <div class="col-md-4" id="hostgrouptree">

  </div>

  <div class="col-md-6">
    <button id="btn-get-hostgroup" type="button" class="btn btn-default">获取选中的组</button>
  </div>
