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:

{* ../../docs_src/path_params/tutorial004.py hl[6] *}

/// 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。

この場合、URLは `files` と `home` の間にダブルスラッシュ (`//`) のある、 `/files//home/johndoe/myfile.txt` になります。
