Scenario 1: Sometimes the structure of the key we see after formatting the json is like this, but the key cannot be found through code analysis Scenario 2: Sometimes
we cannot determine the structure of the json, we can only judge whether the key is in In this json, and return the position of the key in json
At the same time, you can also find the corresponding position according to the value
```python
import json
import jsonpath
import ast
class HandleJson():
def __init__(self, data):

try:
self.data = ast.literal_eval(data)
except:
pass
elif isinstance(data, dict):
self.data = data

'''
用于遍历json树
:param data: 原始数据，或者key对应的value值
:param path: key值字符串，默认值为''
:return:

if isinstance(data, dict):
for k, v in data.items():
tmp = path + "['%s']" % k
yield (tmp, v)
yield from self.__paths(v, tmp)
if isinstance(data, list):
for k, v in enumerate(data):
tmp = path + '[%d]' % k
yield (tmp, v)
yield from self.__paths(v, tmp)
