loads和dumps的用法

Posted 2022-05-17 tzxy

import json

s=‘"name":"wuxie","sex":"m","data":null‘
dict1=json.loads(s)#load 字符串转字典。可将null变为none
print(type(dict1),dict1)
#---------------------------------------------
d="name":"wuxie","sex":"m","data":None
str1=json.dumps(d)#字典转字符串，可将none变为null
print(type(str1),str1)

----------------运行结果-------------
<class ‘dict‘> ‘name‘: ‘wuxie‘, ‘sex‘: ‘m‘, ‘data‘: None
<class ‘str‘> "name": "wuxie", "sex": "m", "data": null

　　

import requests
import json
get_result=requests.get("http://v.juhe.cn/certificates/typeList.php",params="key":"")
post_result=requests.post(url="http://v.juhe.cn/certificates/typeList.php",data="key":"feff6a9dcd1191d36ae0145739c50afc")
s=json.dumps(get_result.json(),ensure_ascii=True)#字典转字符串，将none转变为null，ascii编码为true时，请求信息是乱码
#解决乱码
# s=json.dumps(get_result.json(),ensure_ascii=False)#ASCII编码改为False
print(s)
print(post_result.text)

--------运行结果-------------
