/// 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

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**（`//`）。

	Você poderia precisar que o parâmetro contivesse `/home/johndoe/myfile.txt`, com uma barra no inicio (`/`).

	Neste caso, a URL deveria ser: `/files//home/johndoe/myfile.txt`, com barra dupla (`//`) entre `files` e `home`.
