## `StaticFiles` verwenden

* Importieren Sie `StaticFiles`.
* „Mounten“ Sie eine `StaticFiles()`-Instanz in einem bestimmten Pfad.

```Python hl_lines="2  6"
{!../../../docs_src/static_files/tutorial001.py!}
```

!!! note "Technische Details"
    Sie könnten auch `from starlette.staticfiles import StaticFiles` verwenden.

 *
 * <p>{@link java.nio.file.Path} users will find similar utilities in {@link MoreFiles} and the
 * JDK's {@link java.nio.file.Files} class.

### <a href="https://github.com/encode/apistar" class="external-link" target="_blank">APIStar</a> (≦ 0.5)

Kurz bevor ich mich entschied, **FastAPI** zu erstellen, fand ich den **APIStar**-Server. Er hatte fast alles, was ich suchte, und ein tolles Design.

    InputStream in = new ByteArrayInputStream(PRE_FILLED_100);
    byte[] b = ByteStreams.toByteArray(in, 100);
    assertThat(b).isEqualTo(PRE_FILLED_100);
  }

  public void testToByteArray_withSize_givenSmallerSize() throws IOException {
    InputStream in = new ByteArrayInputStream(PRE_FILLED_100);
    byte[] b = ByteStreams.toByteArray(in, 80);
    assertThat(b).isEqualTo(PRE_FILLED_100);
  }

    例如，`pip install python-multipart`。

## 导入 `File` 与 `Form`

```Python hl_lines="1"
{!../../../docs_src/request_forms_and_files/tutorial001.py!}
```

## 定义 `File` 与 `Form` 参数

创建文件和表单参数的方式与 `Body` 和 `Query` 一样：

```Python hl_lines="8"
{!../../../docs_src/request_forms_and_files/tutorial001.py!}
```

文件和表单字段作为表单数据上传与接收。

声明文件可以使用 `bytes` 或 `UploadFile` 。

!!! note "기술적 세부사항"
    `from starlette.staticfiles import StaticFiles` 를 사용할 수도 있습니다.

    **FastAPI**는 단지 개발자인, 당신에게 편의를 제공하기 위해 `fastapi.static files` 와 동일한 `starlett.static files`를 제공합니다. 하지만 사실 이것은 Starlett에서 직접 온 것입니다.
