## 安装服务器程序

当您安装 FastAPI 时，它自带一个生产环境服务器——Uvicorn，并且您可以使用 `fastapi run` 命令来启动它。

不过，您也可以手动安装 ASGI 服务器。

请确保您创建并激活一个[虚拟环境](../virtual-environments.md){.internal-link target=_blank}，然后再安装服务器应用程序。

例如，要安装 Uvicorn，可以运行以下命令：

<div class="termy">

```console
$ pip install "uvicorn[standard]"

---> 100%
```

</div>

类似的流程也适用于任何其他 ASGI 服务器程序。

Se você não quer utilizar os modelos Pydantic, você também pode utilizar o parâmetro **Body**. Veja a documentação para [Body - Parâmetros múltiplos: Valores singulares no body](body-multiple-params.md#singular-values-in-body){.internal-link target=_blank}....

### Étape 5 : retourner le contenu

{* ../../docs_src/first_steps/tutorial001.py hl[8] *}

Благодаря ✨ [**спонсорству FastAPI**](../help-fastapi.md#sponsor-the-author){.internal-link target=_blank} ✨ эти компании помогают обеспечивать, чтобы фреймворк и его **экосистема** оставались здоровыми и **устойчивыми**.

OpenAPI doesn't support a way to declare a *path parameter* to contain a *path* inside, as that could lead to scenarios that are difficult to test and define.

Nevertheless, you can still do it in **FastAPI**, using one of the internal tools from Starlette.

And the docs would still work, although not adding any documentation telling that the parameter should contain a path.

### Path convertor { #path-convertor }

You can of course also pass multiple `examples`:

{* ../../docs_src/schema_extra_example/tutorial004_an_py310.py hl[23:38] *}

When you do this, the examples will be part of the internal **JSON Schema** for that body data.
