!!! tip "Tipp"
    Der Parameter könnte einen führenden Schrägstrich (`/`) haben, wie etwa in `/home/johndoe/myfile.txt`.

    In dem Fall wäre die URL: `/files//home/johndoe/myfile.txt`, mit einem doppelten Schrägstrich (`//`) zwischen `files` und `home`.

## Zusammenfassung

In **FastAPI** erhalten Sie mittels kurzer, intuitiver Typdeklarationen:

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

!!! tip
    You could need the parameter to contain `/home/johndoe/myfile.txt`, with a leading slash (`/`).

    In that case, the URL would be: `/files//home/johndoe/myfile.txt`, with a double slash (`//`) between `files` and `home`.

## Recap

With **FastAPI**, by using short, intuitive and standard Python type declarations, you get:

{!../../../docs_src/path_params/tutorial004.py!}
```

!!! tip "Подсказка"
    Возможно, вам понадобится, чтобы параметр содержал `/home/johndoe/myfile.txt` с ведущим слэшем (`/`).

    В этом случае URL будет таким: `/files//home/johndoe/myfile.txt`, с двойным слэшем (`//`) между `files` и `home`.

## Резюме
Используя **FastAPI** вместе со стандартными объявлениями типов Python (короткими и интуитивно понятными), вы получаете:

用法如下：

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

!!! tip "提示"

    注意，包含 `/home/johndoe/myfile.txt` 的路径参数要以斜杠（`/`）开头。

    本例中的 URL 是 `/files//home/johndoe/myfile.txt`。注意，`files` 和 `home` 之间要使用**双斜杠**（`//`）。

## 小结

通过简短、直观的 Python 标准类型声明，**FastAPI** 可以获得：

- 编辑器支持：错误检查，代码自动补全等

```

!!! tip "Astuce"
    Vous pourriez avoir besoin que le paramètre contienne `/home/johndoe/myfile.txt`, avec un slash au début (`/`).

    Dans ce cas, l'URL serait : `/files//home/johndoe/myfile.txt`, avec un double slash (`//`) entre `files` et `home`.

## Récapitulatif

Starten Sie nun Traefik:

<div class="termy">

```console
$ ./traefik --configFile=traefik.toml

INFO[0000] Configuration loaded from file: /home/user/awesomeapi/traefik.toml
```

</div>

Und jetzt starten Sie Ihre Anwendung mit Uvicorn, indem Sie die Option `--root-path` verwenden:

<div class="termy">

```console

Se você instalou Typer CLI, você pode instalar _completion_ com:

<div class="termy">

```console
$ typer --install-completion

zsh completion installed in /home/user/.bashrc.
Completion will take effect once you restart the terminal.
```

</div>
