python递归解析JSON（目前最好的
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_function
import json
def 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 indict
if __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 : 0
base_config.enforce.inherit : 0
base_config.enforce.global : 0
base_config.modify.value : 0
base_config.modify.inherit : 0
base_config.modify.global : 0
safe_control_list.list.gid : 0
safe_control_list.list.gname : 全网计算机
safe_control_list.list.isactive : 1
safe_control_list.list.rule_id : 0
safe_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 : 1
safe_control_list.list.policy_tpl : 33
safe_control_list.list.policy_tpl_id : 17
safe_control_list.list.isonline : 3
safe_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
detail.baseline.cancel_scheduled_task : 1
detail.baseline.comeonstage : topwin
detail.baseline.conf_ver : 2635792175
detail.baseline.conf_ver_s : f7f8ac46##

detail.baseline.scheduled_task : 1

detail.baseline.scheduled_task_rule.extra.countdown_type : 3600
detail.baseline.scheduled_task_rule.extra.cycle_type : 1
detail.baseline.scheduled_task_rule.extra.every_type : 1
detail.baseline.scheduled_task_rule.gid : 0
detail.baseline.scheduled_task_rule.is_notice : 1
detail.baseline.scheduled_task_rule.is_reportback : 0
detail.baseline.scheduled_task_rule.module_id : 3
detail.baseline.scheduled_task_rule.name :
detail.baseline.scheduled_task_rule.notice_msg :
detail.baseline.scheduled_task_rule.status : 1
detail.baseline.scheduled_task_rule.tpl_id : 420
detail.baseline.scheduled_task_rule.type : 1
id : 1
type : 2100如果大家在使用过程中有任何问题，希望告知，我加以完善！！！
