jsonpath 类的用法

import json

#字典 ==> json
test_dict = {"key1":"val1","key2":None,"key3":True,"key4":False}
new_json = json.dumps(test_dict)
print(type(new_json),new_json)     #<class 'str'> {"key1": "val1", "key2": null, "key3": true, "key4": false}
"""
字典与json之间存在差异：
dict = {"key1": "val1", "key2": None, "key3": True, "key4": False}
json = {"key1": "val1", "key2": null, "key3": true, "key4": false}
"""

#json ==> 字典
finally_dict = json.loads(new_json)
print(type(finally_dict),finally_dict)    #<class 'dict'> {'key1': 'val1', 'key2': None, 'key3': True, 'key4': False}

from jsonpath import jsonpath
from pprint import pprint
from Demo2 import test_dic
#result(list) = jsonpath(dic,表达式)
#result = jsonpath(test_dic,"$[user_info]")
#result = jsonpath(test_dic,"$[user_info][China]")
#result = jsonpath(test_dic,"$..China")    #模糊递归搜索 $..
#result = jsonpath(test_dic,"$..China[0,1]")    #索引搜索
#result = jsonpath(test_dic,"$..China[2:4]")    #切片搜索
#result = jsonpath(test_dic,"$..China[[name,age,heighet]]")    #获取指定字段
#result = jsonpath(test_dic,"$..China.[name,age,heighet]")     #获取指定字段
result = jsonpath(test_dic,"$..user_info.[?(@.age<25 && @.sex=='女')]")      #过滤表达式搜索   && 和 ||

pprint(result)
