python中dict轉換爲對象屬性（包含json轉換）

1.json轉換爲dict

import json
d = '{"person":[{"firstName":"Brett","lastName":"McLaughlin","email":"aaaa"},{"firstName":"Jason","lastName":"Hunter","email":"bbbb"},{"firstName":"Elliotte","lastName":"Harold","email":"cccc"}]}'

dict_ = json.loads(d)

print(dict_)

2.dict轉爲json

j = json.dumps(dict_)
print(j)

3.dict轉爲對象屬性

class DictObj(object):
    def __init__(self,map):
        self.map = map

    def __setattr__(self, name, value):
        if name == 'map':
             object.__setattr__(self, name, value)
             return;
        print ('set attr called ',name,value)
        self.map[name] = value

    def __getattr__(self,name):
        v = self.map[name]
        if isinstance(v,(dict)):
            return DictObj(v)
        if isinstance(v, (list)):
            r = []
            for i in v:
                r.append(DictObj(i))
            return r
        else:
            return self.map[name];

    def __getitem__(self,name):
        return self.map[name]
