- schemabuilder.Str
- schemabuilder.Bool
- schemabuilder.Number
- schemabuilder.Int
- schemabuilder.Object
- schemabuilder.Array
>>>importschemabuilderasjsb>>>importpprint>>>>>>name=jsb.Str(pattern="^[a-zA-Z][- 'a-zA-Z0-9]+")>>>email=jsb.Str(format="email")>>>user=jsb.Object(properties={...'name':name(required=True),...'email':email(),...'home':jsb.Str(format='uri'),...})>>>pprint.pprint(user.to_dict()){'properties':{'email':{'type':'string'},'home':{'format':'uri','type':'string'},'name':{'type':'string'}},'required':['name'],'type':'object'}
模式
schema收集这些定义进行验证（使用jsonschema）或 出版。
