python之json模块

json字符串对象转字典，采用loads方法，当转换后的字典有Boolean类型的时候，要注意json字符串的值小写：

import json
a='{"CityId":18,"CityName":"西安","ProvinceId":27,"CityOrder":1,"c":null,"d":true,"e":false}'
b=json.loads(a)
print (b)
print (type(b))
print (b["d"])
print (type(b["d"]))

E:python36python3.exe E:/uiautomator/test.py
{'CityId': 18, 'CityName': '西安', 'ProvinceId': 27, 'CityOrder': 1, 'c': None, 'd': True, 'e': False}
<class 'dict'>
True
<class 'bool'>

字典转json字符串，采用dumps方法，如果转换的字典带有中文需要带参数ensure_ascii = False，确保原样输出：

import json
a={"CityId":18,"CityName":"西安","ProvinceId":27,"CityOrder":1,"c":False}
b=json.dumps(a,ensure_ascii = False)
print (b)
print (type(b))

E:python36python3.exe E:/uiautomator/test.py
{"CityId": 18, "CityName": "西安", "ProvinceId": 27, "CityOrder": 1, "c": false}
<class 'str'>
