into the [SSE wire format](https://html.spec.whatwg.org/multipage/server-sent-events.html#parsing-an-event-stream)
    (`text/event-stream`).

    If you yield a plain object (dict, Pydantic model, etc.) instead, it is
    automatically JSON-encoded and sent as the `data:` field.

    All `data` values **including plain strings** are JSON-serialized.

```

...这个响应将返回：

```json
{
  "message": "Hello World"
}
```

当然，你很可能会找到比格式化 JSON 更好的方式来利用这一点。😉

### `orjson` 或响应模型 { #orjson-or-response-model }

如果你追求的是性能，使用[响应模型](../tutorial/response-model.md) 往往比返回 `orjson` 响应更好。

使用响应模型时，FastAPI 会使用 Pydantic 直接把数据序列化为 JSON，不需要诸如通过 `jsonable_encoder` 转换这样的中间步骤（其他情况下会发生）。

并且在底层，Pydantic 使用与 `orjson` 相同的 Rust 机制来序列化 JSON，所以使用响应模型你已经可以获得最佳性能。

    * Convert Python types (`str`, `int`, `float`, `bool`, `list`, etc).
    * `datetime` objects.
    * `UUID` objects.
    * Database models.
    * ...and many more.
* Automatic interactive API documentation, including 2 alternative user interfaces:
    * Swagger UI.
    * ReDoc.

Coming back to the previous code example, **FastAPI** will:

### Memória por Processo { #memory-per-process }

Agora, quando o programa carrega coisas na memória, por exemplo, um modelo de aprendizado de máquina em uma variável, ou o conteúdo de um arquivo grande em uma variável, tudo isso **consome um pouco da memória (RAM)** do servidor.

  <!-- This module was also published with a richer model, Gradle metadata,  -->
  <!-- which should be used instead. Do not delete the following line which  -->
  <!-- is to indicate to Gradle or any Gradle module metadata file consumer  -->

{* ../../docs_src/response_headers/tutorial002_py310.py hl[1, 7:8] *}

Ensuite, vous pouvez renvoyer n'importe quel objet dont vous avez besoin, comme d'habitude (un `dict`, un modèle de base de données, etc.).

Et si vous avez déclaré un `response_model`, il sera toujours utilisé pour filtrer et convertir l'objet que vous avez renvoyé.
