Python实现复杂对象转JSON的方法示例

本文实例讲述了Python实现复杂对象转JSON的方法。分享给大家供大家参考,具体如下:

在Python对于简单的对象转json还是比较简单的,如下:

import json

d = {'a': 'aaa', 'b': ['b1', 'b2', 'b3'], 'c': 100}

json_str = json.dumps(d)

print json_str

对于复杂对象,可以使用下面的方法来实现,比如:

import json

class Customer:

def __init__(self, name, grade, age, home, office):

self.name = name

self.grade = grade

self.age = age

self.address = Address(home, office)

def __repr__(self):

return repr((self.name, self.grade, self.age, self.address.home, self.address.office))

class Address:

def __init__(self, home, office):

self.home = home

self.office = office

def __repr__(self):

return repr((self.name, self.grade, self.age))

customers = [

Customer('john', 'A', 15, '111', 'aaa'),

Customer('jane', 'B', 12, '222', 'bbb'),

Customer('dave', 'B', 10, '333', 'ccc'),

]

json_str = json.dumps(customers, default=lambda o: o.__dict__, sort_keys=True, indent=4)

print json_str

结果如下

[

{

"address": {

"home": "111",

"office": "aaa"

},

"age": 15,

"grade": "A",

"name": "john"

},

{

"address": {

"home": "222",

"office": "bbb"

},

"age": 12,

"grade": "B",

"name": "jane"

},

{

"address": {

"home": "333",

"office": "ccc"

},

"age": 10,

"grade": "B",

"name": "dave"

}

]
