我希望编写一个json模式来涵盖此（简化）示例

{
    "errorMessage": "",
    "nbRunningQueries": 0,
    "isError": False,
    "result": {
        "foo": {"price":10.0, "country":"UK"},
        "bar": {"price":100.2, "country":"UK"}
    }
}

可以有这个非常琐碎的根架构

schema = {
    "type":"object",
    "required":True,
    "properties":{
        "errorMessage": {"type":"string", "required":True},
        "isError": {"type":"boolean", "required":True},
        "nbRunningQueries": {"type":"number", "required":True},
        "result": {"type":"object","required":True}
    }
}

复杂的是结果{}元素。与标准模式不同，在标准模式中，结果将是相同对象的数组-每个对象都有一个id字段或类似的对象，此响应将模拟一个python字典，如下所示：

{
    "foo": {},
    "bar": {},
    ...
}

因此，鉴于a将获得没有设置键的灵活大小的结果对象，我如何为此编写json模式？

我不会伤心地控制输入，否则我会将其重写为类似

{
    "errorMessage": "",
    "nbRunningQueries": 0,
    "isError": False,
    "result": [
        {"id": "foo", "price":10.0, "country": "UK"},
        {"id": "bar", "price":100.2, "country":"UK"}
    ]
}

任何帮助或相关示例的链接都将非常有用。谢谢。

新的扭曲,只是尝试一些延期的东西.我有以下代码组成100个延迟调用的列表 - 每个等待一个随机时间并返回一个值.该列表打印结果并最终终止反应器.

但是,我很确定我停止反应堆的方式可能......不太好.
