我们要完成的任务是输出JSON字典，并且对其中的每个元素，要输出它的所有父节点。那么很容易想到的做法就是递归解析。

我参考了别人的一些文章和回答，总结了如下的解决方案：

from __future__ import print_functionimport jsondef dict_generator(indict, pre=None):    pre = pre[:] if pre else []    if isinstance(indict, dict):        for key, value in indict.items():            if isinstance(value, dict):                if len(value) == 0:                    yield pre+[key, '{}']                else:                    for d in dict_generator(value, pre + [key]):                        yield d            elif isinstance(value, list):                if len(value) == 0:                                       yield pre+[key, '[]']                else:                    for v in value:                        for d in dict_generator(v, pre + [key]):                            yield d            elif isinstance(value, tuple):                if len(value) == 0:                    yield pre+[key, '()']                else:                    for v in value:                        for d in dict_generator(v, pre + [key]):                            yield d            else:                yield pre + [key, value]    else:        yield indictif __name__ == "__main__":    sJOSN =  ''    sValue = json.loads(sJOSN)    for i in dict_generator(sValue):        print('.'.join(i[0:-1]), ':', i[-1])

我对于以下几个例子做出测试

{
       "base_config":{
           "enforce":{
               "value":"0",            "inherit":"0",            "global":"0"        },        "modify":{
               "value":"0",            "inherit":"0",            "global":"0"        }    },    "safe_control_list":{
           "list":[            {
                   "gid":"0",                "gname":"全网计算机",                "isactive":"1",                "rule_id":"0",                "rule_name":"请选择规则",                "time_range":"所有时间",                "time_range_id":"1",                "policy_tpl":"33",                "policy_tpl_id":"17",                "isonline":"3",                "priority":"1"            }        ]    }}

测试结果如下

base_config.enforce.value : 0base_config.enforce.inherit : 0base_config.enforce.global : 0base_config.modify.value : 0base_config.modify.inherit : 0base_config.modify.global : 0safe_control_list.list.gid : 0safe_control_list.list.gname : 全网计算机safe_control_list.list.isactive : 1safe_control_list.list.rule_id : 0safe_control_list.list.rule_name : 请选择规则safe_control_list.list.time_range : 所有时间safe_control_list.list.time_range_id : 1safe_control_list.list.policy_tpl : 33safe_control_list.list.policy_tpl_id : 17safe_control_list.list.isonline : 3safe_control_list.list.priority : 1

使用另外一个测试用例

{
       "detail":{
           "baseline":{
               "cancel_scheduled_task":"1",            "comeonstage":"topwin",            "conf_ver":2635792175,            "conf_ver_s":"f7f8ac46##",            "mission_id":0,            "rules":{
               },            "scheduled_task":"1",            "scheduled_task_rule":{
                   "autoexec_on_coundown":"1",                "exec_countdown":"0",                "exec_interval":"0",                "exec_mode":"4",                "exec_time":"*|00|*|*|*",                "extra":{
                       "countdown_type":"3600",                    "cycle_type":"1",                    "every_type":"1"                },                "gid":0,                "is_notice":"1",                "is_reportback":"0",                "module_id":3,                "name":"",                "notice_msg":"",                "status":1,                "tpl_id":420,                "type":1            }        }    },    "id":1,    "type":2100}

测试结果如下

如果大家在使用过程中有任何问题，希望告知，我加以完善！！！
