/// tip | Astuce

`aGVsbG8=` est l'encodage base64 de `hello`.

///

Pydantic décodera ensuite la chaîne base64 et vous fournira les octets originaux dans le champ `data` du modèle.

Vous recevrez une réponse comme :

```json
{
  "description": "Some data",
  "content": "hello"
}
```

```json

```

/// tip | 豆知識

`aGVsbG8=` は `hello` の base64 エンコードです。

///

その後、Pydantic は base64 文字列をデコードし、モデルの `data` フィールドに元のバイト列を渡します。

次のようなレスポンスを受け取ります:

```json
{
  "description": "Some data",
  "content": "hello"
}
```

## 出力データ向けの Pydantic `bytes` { #pydantic-bytes-for-output-data }

    val request =
      Request(
        url = server.url("/"),
        body = "hello".toRequestBody(),
      )
    client.newCall(request).execute().use { response ->
      assertThat(response.body.string()).isEqualTo("")
    }
    val recordedRequest = server.takeRequest()
    assertThat(recordedRequest.body).isEqualTo("hello".encodeUtf8())
  }
