次の場所からデータを取得します:

- パスのパラメータ
- ヘッダー
- クッキー
- など

こうすることで、**FastAPI** はそのデータを検証し、変換し、API のドキュメントを自動生成します。

しかし、`Request` オブジェクトに直接アクセスする必要がある場面もあります。

## `Request` オブジェクトの詳細 { #details-about-the-request-object }

**FastAPI** は内部的には **Starlette** の上にいくつかのツール層を載せたものなので、必要に応じて Starlette の [`Request`](https://www.starlette.dev/requests/) オブジェクトを直接使えます。

Kotlin calling OkHttp 3.x:

```kotlin
val client = OkHttpClient.Builder()
    .dns { hostname -> InetAddress.getAllByName(hostname).toList() }
    .build()
```

Kotlin calling OkHttp 4.x:

```kotlin
val client = OkHttpClient.Builder()
    .dns(object : Dns {
      override fun lookup(hostname: String) =

        lenient().when(locator.getURL()).thenReturn(smbUrl);
