And if you see the resulting OpenAPI (at `/openapi.json` in your API), you will see your extension as part of the specific *path operation* too:

```JSON hl_lines="22"
{
    "openapi": "3.1.0",
    "info": {
        "title": "FastAPI",
        "version": "0.1.0"
    },
    "paths": {
        "/items/": {

```Python hl_lines="6"
{!../../../docs_src/path_operation_advanced_configuration/tutorial005.py!}
```

Wenn Sie die automatische API-Dokumentation öffnen, wird Ihre Erweiterung am Ende der spezifischen *Pfadoperation* angezeigt.

Vous devez vous assurer qu'il est unique pour chaque opération.

// pathNeedsClean returns whether path.Clean may change the path.
// Will detect all cases that will be cleaned,
// but may produce false positives on non-trivial paths.
func pathNeedsClean(path []byte) bool {
	if len(path) == 0 {

	}

	rooted := path[0] == '/'

	for r < n {

```
/files/{file_path:path}
```

In diesem Fall ist der Name des Parameters `file_path`. Der letzte Teil, `:path`, sagt aus, dass der Parameter ein *Pfad* sein soll.

Sie verwenden das also wie folgt:

```

repository for all Gradle builds. Gradle will check hashes (md5 and sha256) of used dependencies and will fail builds with
`Dependency verification failed` errors when local artifacts are absent or have different hashes listed in the
[verification-metadata.xml](https://github.com/JetBrains/kotlin/blob/master/gradle/verification-metadata.xml) file.

### パス変換

Starletteのオプションを直接使用することで、以下のURLの様な*パス*を含んだ、*パスパラメータ*の宣言ができます:

```
/files/{file_path:path}
```

この場合、パラメータ名は `file_path` です。そして、最後の部分 `:path` はパラメータがいかなる*パス*にもマッチすることを示します。

したがって、以下の様に使用できます:

```Python hl_lines="6"
{!../../../docs_src/path_params/tutorial004.py!}
```

!!! tip "豆知識"
    最初のスラッシュ (`/`)が付いている `/home/johndoe/myfile.txt` をパラメータが含んでいる必要があります。
