			- 媒体类型的密钥，例如 `application/json` ，它包含另一个`JSON`对象作为值，该对象包含：
				- 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。


**在OpenAPI中为该路径操作生成的响应将是：**

A função não retorna um grande `str` contendo os dados no formato JSON (como uma string). Mas sim, retorna uma estrutura de dados padrão do Python (por exemplo, um `dict`) com valores e subvalores compatíveis com JSON.
