Você pode adicionar um `title`:

```Python hl_lines="10"
{!../../docs_src/query_params_str_validations/tutorial007.py!}
```

E uma `description`:

```Python hl_lines="13"
{!../../docs_src/query_params_str_validations/tutorial008.py!}
```

## Apelidos (alias) de parâmetros

Imagine que você queira que um parâmetro tenha o nome `item-query`.

Desta maneira:

```

```Python
images: List[Image]
```

or in Python 3.9 and above:

```Python
images: list[Image]
```

as in:

//// tab | Python 3.9+

```Python hl_lines="13"
{!> ../../docs_src/body_nested_models/tutorial008_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="15"
{!> ../../docs_src/body_nested_models/tutorial008.py!}
```

////

```Python hl_lines="9  17"
{!> ../../docs_src/request_files/tutorial001_02.py!}
```

////

## 带有额外元数据的 `UploadFile`

您也可以将 `File()` 与 `UploadFile` 一起使用，例如，设置额外的元数据:

```Python hl_lines="13"
{!../../docs_src/request_files/tutorial001_03.py!}
```

## 多文件上传

FastAPI 支持同时上传多个文件。

可用同一个「表单字段」发送含多个文件的「表单数据」。

上传多个文件时，要声明含 `bytes` 或 `UploadFile` 的列表（`List`）：
