Python复杂对象转JSON
在Python对于简单的对象转json还是比较简单的，如下：
import jsond = {'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 jsonclass 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" }]
