/// tip

Instead of returning a `StreamingResponse` directly, you should probably follow the style in [Stream Data](./stream-data.md), it's much more convenient and handles cancellation behind the scenes for you.

If you are streaming JSON Lines, follow the [Stream JSON Lines](../tutorial/stream-json-lines.md) tutorial.

## Резюме { #recap }

상대 URL을 사용하므로, 예를 들어 API가 `https://example.com/`에 있다면 `https://example.com/token`을 가리킵니다. 하지만 API가 `https://example.com/api/v1/`에 있다면 `https://example.com/api/v1/token`을 가리킵니다.

상대 URL을 사용하는 것은 [프록시 뒤에서](../../advanced/behind-a-proxy.md) 같은 고급 사용 사례에서도 애플리케이션이 계속 동작하도록 보장하는 데 중요합니다.

이 파라미터는 그 endpoint / *경로 처리*를 만들지는 않지만, URL `/token`이 클라이언트가 token을 얻기 위해 사용해야 할 URL이라고 선언합니다. 이 정보는 OpenAPI에 사용되고, 이어서 대화형 API 문서 시스템에서도 사용됩니다.
