### コールバックのパス式 { #the-callback-path-expression }

コールバックの *パス* には、*あなたの API* に送られた元のリクエストの一部を含められる [OpenAPI 3 の式](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#key-expression)を使用できます。

この例では、`str` は次のとおりです:

```Python
"{$callback_url}/invoices/{$request.body.id}"

        secondaryParameterOffset = SECONDARY_PARAMETER_OFFSET;
    }

    @Override
    void reset() {
        super.reset();
        isPrimary = hasMore = true;
    }

    void reset(final int key, final String lastName) {
        reset();
    }

    @Override
    public boolean hasMoreElements() {
        return hasMore;
    }

    @Override
    public Object nextElement() {

Bu durumda, `int` key’lere ve `float` value’lara sahip olduğu sürece herhangi bir `dict` kabul edersiniz:

{* ../../docs_src/body_nested_models/tutorial009_py310.py hl[7] *}

/// tip | İpucu

JSON key olarak yalnızca `str` destekler, bunu unutmayın.

Ancak Pydantic otomatik veri dönüştürme yapar.
