            - 一个键` schema` ，它的值是来自模型的`JSON Schema`，正确的位置在这里。
                - **FastAPI**在这里添加了对OpenAPI中另一个地方的全局JSON模式的引用，而不是直接包含它。这样，其他应用程序和客户端可以直接使用这些JSON模式，提供更好的代码生成工具等。

O **FastAPI** pegará o modelo do Pydantic, gerará o `JSON Schema`, e adicionará no local correto.

O local correto é:

* Na chave `content`, que tem como valor um outro objeto JSON (`dict`) que contém:
    * Uma chave com o media type, como por exemplo `application/json`, que contém como valor um outro objeto JSON, contendo::
        * Uma chave `schema`, que contém como valor o JSON Schema do modelo, sendo este o local correto.
