次のようなリクエストを送れます:

```json
{
    "description": "Some data",
    "data": "aGVsbG8="
}
```

/// 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"
}
```

            "Integer", 0, 0, null, null, false, null, null, null, null, null, false);
    protected final ColumnInfo _columnDescription = cci("description", "description", null, null, String.class, "description", null, false,
            false, false, "text", 0, 0, null, null, false, null, null, null, null, null, false);

この場合、**FastAPI** は以下のようなボディを期待します:

```JSON hl_lines="2"
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    }
}
```

以下の代わりに:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```
