свои собственные заголовки <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">при помощи префикса 'X-'</a>.

Если же вы хотите добавить собственные заголовки, которые клиент сможет увидеть в браузере, то вам потребуется добавить их в настройки CORS ([CORS (Cross-Origin Resource Sharing)](cors.md){.internal-link target=_blank}), используя параметр `expose_headers`, см. документацию <a href="https://www.starlette.dev/middleware/#corsmiddleware"...

It is based on <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, which in turn is designed based on Requests, so it's very familiar and intuitive.

With it, you can use <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a> directly with **FastAPI**.

Оскільки HTTPX розроблений на основі Requests, його API є інтуїтивно зрозумілим для тих, хто вже знайомий з Requests.

З його допомогою Ви можете використовувати <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a> безпосередньо з **FastAPI**.
