### Use your tags { #use-your-tags }

Use the `tags` parameter with your *path operations* (and `APIRouter`s) to assign them to different tags:

{* ../../docs_src/metadata/tutorial004.py hl[21,26] *}

/// info

Read more about tags in [Path Operation Configuration](path-operation-configuration.md#tags){.internal-link target=_blank}.

///

### Check the docs { #check-the-docs }

But remember that when you import `Query`, `Path`, `File` and others from `fastapi`, those are actually functions that return special classes.

///

/// tip

To declare File bodies, you need to use `File`, because otherwise the parameters would be interpreted as query parameters or body (JSON) parameters.

///

The files will be uploaded as "form data".

/// tip | 豆知識

使用するすべてのタグにメタデータを追加する必要はありません。

///

### 自作タグの使用

`tags` パラメーターを使用して、それぞれの *path operations* (および `APIRouter`) を異なるタグに割り当てます:

{* ../../docs_src/metadata/tutorial004.py hl[21,26] *}

/// info | 情報

タグのより詳しい説明を知りたい場合は [Path Operation Configuration](path-operation-configuration.md#tags){.internal-link target=_blank} を参照して下さい。

Swagger UI will handle it behind the scenes for you, but it needs this "redirect" helper.

### Create a *path operation* to test it { #create-a-path-operation-to-test-it }

Now, to be able to test that everything works, create a *path operation*:

{* ../../docs_src/custom_docs_ui/tutorial001.py hl[36:38] *}

### Test it { #test-it }

# Body - Paramètres multiples

Maintenant que nous avons vu comment manipuler `Path` et `Query`, voyons comment faire pour le corps d'une requête, communément désigné par le terme anglais "body".

## Mélanger les paramètres `Path`, `Query` et body

Tout d'abord, sachez que vous pouvez mélanger les déclarations des paramètres `Path`, `Query` et body, **FastAPI** saura quoi faire.

    val c = this[i]
    if (c == '%' || c == '+' && plusIsSpace) {
      // Slow path: the character at i requires decoding!
      val out = Buffer()
      out.writeUtf8(this, pos, i)
      out.writePercentDecoded(this, pos = i, limit = limit, plusIsSpace = plusIsSpace)
      return out.readUtf8()
    }
  }

  // Fast path: no characters in [pos..limit) required decoding.
  return substring(pos, limit)
}
