python之Python 中的类型化 JSON 序列化/反序列化

class Person: 
    first_name = superjson.Property() 
    last_name = superjson.Property() 
    posts = superjson.Collection(Post) 
 
class Post: 
    title = superjson.Property() 
    description = superjson.Property() 
 
# ^^^ this approach is very similar to Django models/forms 

然后，给定这样的 JSON:

{ 
  "first_name": "John",  
  "last_name": "Smith", 
  "posts": [ 
    {"title": "title #1", "description": "description #1"}, 
    {"title": "title #2", "description": "description #2"}, 
    {"title": "title #3", "description": "description #3"} 
  ] 
} 

我希望它构建一个适当的 Person 对象，其中设置了所有内容:

p = superjson.deserialize(json, Person) # note, root type is explicitly provided 
print p.first_name # 'John' 
print p.last_name # 'Smith' 
print p.posts[0].title # 'title #1' 
# etc... 

• 当然它也应该有助于序列化
• 它应该默认将时间序列化/反序列化到 ISO-8601 或从 ISO-8601 中序列化/反序列化时间，或者通过几行代码轻松实现。

所以，我正在寻找这个 superjson。有人看到类似的东西吗？

请您参考如下方法:

Colander , 结合 limone正是这样做的。

您使用 colander 定义模式:

import colander 
import limone 
 
 
@limone.content_schema 
class Characteristic(colander.MappingSchema): 
    id = colander.SchemaNode(colander.Int(), 
                             validator=colander.Range(0, 9999)) 
    name = colander.SchemaNode(colander.String()) 
    rating = colander.SchemaNode(colander.String())         
 
 
class Characteristics(colander.SequenceSchema): 
    characteristic = Characteristic() 
 
 
@limone.content_schema 
class Person(colander.MappingSchema): 
    id = colander.SchemaNode(colander.Int(), 
                             validator=colander.Range(0, 9999)) 
    name = colander.SchemaNode(colander.String()) 
    phone = colander.SchemaNode(colander.String()) 
    characteristics = Characteristics() 
 
 
class Data(colander.SequenceSchema): 
    person = Person() 

然后传入你的JSON数据结构:

deserialized = Data().deserialize(json.loads(json_string))
