调用它的结果后就可以使用Python标准编码中的<a href="https://docs.python.org/3/library/json.html#json.dumps" class="external-link" target="_blank">`json.dumps()`</a>。

这个操作不会返回一个包含JSON格式（作为字符串）数据的庞大的`str`。它将返回一个Python标准数据结构（例如`dict`），其值和子值都与JSON兼容。

/// note

`jsonable_encoder`实际上是FastAPI内部用来转换数据的。但是它在许多其他场景中也很有用。

To verify the above sample alert follow below steps

1. Start a distributed MinIO instance (4 nodes setup)
2. Start Prometheus server and AlertManager

`Field` 的工作方式和 `Query`、`Path`、`Body` 相同，参数也相同。

/// note | "技术细节"

实际上，`Query`、`Path` 都是 `Params` 的子类，而 `Params` 类又是 Pydantic 中 `FieldInfo` 的子类。

Pydantic 的 `Field` 返回也是 `FieldInfo` 的类实例。

`Body` 直接返回的也是 `FieldInfo` 的子类的对象。后文还会介绍一些 `Body` 的子类。
