### Importer `Query` et `Annotated` { #import-query-and-annotated }

Pour ce faire, importez d’abord :

- `Query` depuis `fastapi`
- `Annotated` depuis `typing`

{* ../../docs_src/query_params_str_validations/tutorial002_an_py310.py hl[1,3] *}

/// info

FastAPI a ajouté la prise en charge de `Annotated` (et a commencé à le recommander) dans la version 0.95.0.

 *  **Timeouts now default to 10 seconds.** Previously we defaulted to never
    timing out, and that was a lousy policy. If establishing a connection,
    reading the next byte from a connection, or writing the next byte to a
    connection takes more than 10 seconds to complete, you’ll need to adjust

### Importar `Query` y `Annotated` { #import-query-and-annotated }

Para lograr eso, primero importa:

* `Query` desde `fastapi`
* `Annotated` desde `typing`

{* ../../docs_src/query_params_str_validations/tutorial002_an_py310.py hl[1,3] *}

/// info | Información

FastAPI añadió soporte para `Annotated` (y empezó a recomendarlo) en la versión 0.95.0.

- Use proper authentication header:
  ```bash
  curl -u admin:admin ...
  # or
  curl -H "Authorization: Basic YWRtaW46YWRtaW4=" ...
  ```

#### Issue: Large bulk imports timing out

**Solution**:
- Split large files into smaller batches (e.g., 10,000 docs per file)
- Increase timeout in `system.properties`:
  ```properties
  crawler.document.request.timeout=600000
  ```

Emin değilseniz, normal `def` kullanın.

---

Not: *path operasyon fonksiyonlarınızda* `def` ve `async def`'i ihtiyacınız kadar karıştırabilirsiniz, her birini sizin için en iyi seçenekle tanımlayın. FastAPI onlar için doğru olanı yapacaktır.

Yukarıdaki durumların herhangi birinde FastAPI yine de asenkron olarak çalışır ve son derece hızlıdır.
