* `path` - The filepath to the file to stream.
* `headers` - Any custom headers to include, as a dictionary.
* `media_type` - A string giving the media type. If unset, the filename or path will be used to infer a media type.
* `filename` - If set, this will be included in the response `Content-Disposition`.

File responses will include appropriate `Content-Length`, `Last-Modified` and `ETag` headers.

### `UploadFile`

`UploadFile` has the following attributes:

* `filename`: A `str` with the original file name that was uploaded (e.g. `myimage.jpg`).
* `content_type`: A `str` with the content type (MIME type / media type) (e.g. `image/jpeg`).

        analysisSession: KtAnalysisSession,
        selectedFqName: FqName,
        fullFqName: FqName,
        contextElement: KtElement,
    ): Collection<KtSymbol> {
        with(analysisSession) {
            val fullSymbolsResolved = resolveKdocFqName(fullFqName, contextElement)
            if (selectedFqName == fullFqName) return fullSymbolsResolved.mapTo(mutableSetOf()) { it.symbol }
            if (fullSymbolsResolved.isEmpty()) {

        expression: KtSimpleNameExpression,
        builder: KtSymbolByFirBuilder,
        fir: FirResolvedImport,
        session: FirSession
    ): List<KtSymbol> {
        val fullFqName = fir.importedFqName
        val selectedFqName = getQualifierSelected(expression, forQualifiedType = false)
        val rawImportForSelectedFqName = buildImport {
            importedFqName = selectedFqName

### `UploadFile`

`UploadFile` имеет следующие атрибуты:

* `filename`: Строка `str` с исходным именем файла, который был загружен (например, `myimage.jpg`).
* `content_type`: Строка `str` с типом содержимого (MIME type / media type) (например, `image/jpeg`).

Dann erstellen Sie eine Datei `traefik.toml` mit:

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

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

Dadurch wird Traefik angewiesen, Port 9999 abzuhören und eine andere Datei `routes.toml` zu verwenden.

!!! tip "Tipp"

然后创建包含如下内容的 `traefik.toml` 文件：

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

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

这个文件把 Traefik 监听端口设置为 `9999`，并设置要使用另一个文件 `routes.toml`。

!!! tip "提示"

    使用端口 9999 代替标准的 HTTP 端口 80，这样就不必使用管理员权限运行（`sudo`）。

接下来，创建 `routes.toml`：

Please rename files so there are no repeats. For example, README.md and
Readme.md would be the same file on Windows. In this test, you would get a
warning for "readme.md" because it makes everything lowercase. There are
repeats of these filename(s) with different casing:
EOF
    find . | tr '[A-Z]' '[a-z]' | sort | uniq -d | tee $BATS_FILE_TMPDIR/repeats
    [[ ! -s $BATS_FILE_TMPDIR/repeats ]]
}

Then create a file `traefik.toml` with:

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

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

This tells Traefik to listen on port 9999 and to use another file `routes.toml`.

!!! tip

!!! tip
    A file starting with a dot (`.`) is a hidden file in Unix-like systems, like Linux and macOS.

    But a dotenv file doesn't really have to have that exact filename.
