Ele terá uma *operação de rota* que receberá um corpo `Invoice`, e um parâmetro de consulta `callback_url` que conterá a URL para o callback.

Essa parte é bastante normal, a maior parte do código provavelmente já é familiar para você:

# クッキーパラメータモデル { #cookie-parameter-models }

もし関連する**複数のクッキー**から成るグループがあるなら、それらを宣言するために、**Pydanticモデル**を作成できます。🍪

こうすることで、**複数の場所**で**そのPydanticモデルを再利用**でき、バリデーションやメタデータを、すべてのパラメータに対して一度に宣言できます。😎

/// note | 備考

この機能は、FastAPIのバージョン `0.115.0` からサポートされています。🤓

/// tip | 豆知識

これと同じテクニックは `Query` 、 `Cookie` 、 `Header` にも適用できます。 😎

machine across multiple computational devices, including multicore CPUs, general purpose GPUs, and custom-designed ASICs known as Tensor Processing Units (TPUs). This architecture gives flexibility to the application developer, whereas in previous “parameter server” designs the management of shared state is built into the system, TensorFlow enables developers to experiment with novel optimizations and training algorithms. TensorFlow supports a variety of applications, with a focus on training and inference...
