파일을 비동기로 스트리밍하여 응답합니다.

다른 응답 유형과는 다른 인수를 사용하여 객체를 생성합니다:

* `path` - 스트리밍할 파일의 경로.
* `headers` - 딕셔너리 형식의 사용자 정의 헤더.
* `media_type` - 미디어 타입을 나타내는 문자열. 설정되지 않은 경우 파일 이름이나 경로를 사용하여 추론합니다.
* `filename` - 설정된 경우 응답의 `Content-Disposition`에 포함됩니다.

파일 응답에는 적절한 `Content-Length`, `Last-Modified`, 및 `ETag` 헤더가 포함됩니다.

{* ../../docs_src/custom_response/tutorial009.py hl[2,10] *}

또한 `response_class` 매개변수를 사용할 수도 있습니다:

# Whether to use site encoding for English documents.
crawler.document.use.site.encoding.on.english=false
# Whether to append data to documents.
crawler.document.append.data=true
# Whether to append filename to documents.
crawler.document.append.filename=false
# Maximum size of alphanumeric terms in documents.
crawler.document.max.alphanum.term.size=20
# Maximum size of symbol terms in documents.
crawler.document.max.symbol.term.size=10

        final String name = pi.getName();
        final String encodedName = URLEncoder.encode(name, Constants.UTF_8_CHARSET).replace("+", "%20");
        response.header("Content-Disposition", "attachment; filename=\"" + name + "\"; filename*=utf-8''" + encodedName);
        response.header("Pragma", "no-cache");
        response.header("Cache-Control", "no-cache");
        response.header("Expires", "Thu, 01 Dec 1994 16:00:00 GMT");

            public String getIndexFieldFiletype() {

            }

            @Override
            public String getIndexFieldFilename() {
                return "filename";
            }

            @Override
            public String getIndexFieldCreated() {
                return "created";
            }

            @Override

	Timestamp       int64  // Timestamp set at the time of initialization.
	TimeLastRefresh int64  // Timestamp for last lock refresh.
	Source          string // Contains line, function and filename requesting the lock.
	Group           bool   // indicates if it was a group lock.
	Owner           string // Owner represents the UUID of the owner who originally requested the lock.

### `UploadFile`

`UploadFile` tiene los siguientes atributos:

* `filename`: Un `str` con el nombre original del archivo que fue subido (por ejemplo, `myimage.jpg`).
* `content_type`: Un `str` con el tipo de contenido (MIME type / media type) (por ejemplo, `image/jpeg`).

* `media_type` – Ein String, der den Medientyp angibt. Wenn nicht gesetzt, wird der Dateiname oder Pfad verwendet, um auf einen Medientyp zu schließen.
* `filename` – Wenn gesetzt, wird das in der `Content-Disposition` der Response eingefügt.

Datei-Responses enthalten die entsprechenden `Content-Length`-, `Last-Modified`- und `ETag`-Header.

## Downloads for v1.2.7


filename | sha256 hash

[kubernetes.tar.gz](https://storage.googleapis.com/kubernetes-release/release/v1.2.7/kubernetes.tar.gz) | `53db157923c17fa7a0addb3e4dfe7d1b9194b9266a87d371a251d5bb790a1832`

Luego crea un archivo `traefik.toml` con:

```TOML hl_lines="3"
[entryPoints]
  [entryPoints.http]
    address = ":9999"

[providers]
  [providers.file]
    filename = "routes.toml"
```

Esto le dice a Traefik que escuche en el puerto 9999 y que use otro archivo `routes.toml`.

/// tip | Consejo

* `headers` - Cualquier header personalizado para incluir, como un diccionario.
* `media_type` - Un string que da el media type. Si no se establece, se usará el nombre de archivo o la path para inferir un media type.
* `filename` - Si se establece, se incluirá en el response `Content-Disposition`.

Los responses de archivos incluirán los headers apropiados `Content-Length`, `Last-Modified` y `ETag`.
