/files/{file_path:path}
```

In this case, the name of the parameter is `file_path`, and the last part, `:path`, tells it that the parameter should match any *path*.

So, you can use it with:

At the same point, you try to trigger the autocomplete with `Ctrl+Space` and you see:

With that, you can scroll, seeing the options, until you find the one that "rings a bell":

### Étape 3 : créer un « chemin d’accès » { #step-3-create-a-path-operation }

#### Chemin { #path }

« Chemin » fait ici référence à la dernière partie de l’URL à partir du premier `/`.

Donc, dans une URL telle que :

```
https://example.com/items/foo
```

... le chemin serait :

```
/items/foo
```

/// info

Un « chemin » est aussi couramment appelé « endpoint » ou « route ».
