python 类对象与json的相互转化

直接上代码

#coding:utf-8
import json

class JSONObject:
    def __init__(self, d):
        self.__dict__ = d

def json2obj(s):
    return json.loads(s, object_hook=JSONObject)

def obj2json(a):
    return json.dumps(a,default=lambda obj:obj.__dict__,sort_keys=True) #indent=4,这个参数用来更好的展示json

a = {"status":1,"info":"发布成功","data":{"id":"52","feed_id":"70"}}
b = json2obj(json.dumps(a))
print(b.info)

print(obj2json(a))
#out-put : 发布成功
#out-put :  {"data": {"feed_id": "70", "id": "52"}, "info": "\u53d1\u5e03\u6210\u529f", "status": 1}
