performance de TechEmpower montrent que les applications **FastAPI** tournant sous Uvicorn comme <a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">étant l'un des frameworks Python les plus rapides disponibles</a>, seulement inférieur à Starlette et Uvicorn (tous deux utilisés au cœur de FastAPI).

Mais en prêtant attention aux tests de performance et aux comparaisons, il faut...

### Check the docs { #check-the-docs }

Now you can start your app and go to <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

You will see your docs have the normal *path operations* and now also some **webhooks**:

/// info

For a more complete explanation of `**user_dict` check back in [the documentation for **Extra Models**](../extra-models.md#about-user-in-dict){.internal-link target=_blank}.

///

## Return the token { #return-the-token }

The response of the `token` endpoint must be a JSON object.

Si tienes una versión anterior, obtendrás errores al intentar usar `Annotated`.

Asegúrate de [Actualizar la versión de FastAPI](../../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} al menos a la 0.95.1 antes de usar `Annotated`.

### Importar `Depends`

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[3] *}

### Declarar la dependencia, en el "dependant"

Nehmen wir an, Sie haben eine benutzerdefinierte Exception `UnicornException`, die Sie (oder eine Bibliothek, die Sie verwenden) `raise`n könnten.

sleep 1

echo "Copying data to source sitea/olockbucket"
./mc cp --quiet /etc/hosts sitea/olockbucket
sleep 1

echo "Verifying the metadata difference between source and target"
if diff -pruN <(./mc stat --no-list --json sitea/bucket/hosts | jq .) <(./mc stat --no-list --json siteb/bucket/hosts | jq .) | grep -q 'COMPLETED\|REPLICA'; then
	echo "verified sitea-> COMPLETED, siteb-> REPLICA"
fi

    } catch (ClassCastException e) {
      return false;
    }
  }

  @Override
  public boolean containsAll(Collection<?> targets) {
    for (Object target : targets) {
      if (target == null) {
        // This set never contains null.  We need to explicitly check here
        // because some comparator might throw NPE (e.g. the natural ordering).
        return false;
      }
    }

        "bar",
        "foo"
    ]
}
```

## Zusammenfassung

Deklarieren Sie Header mittels `Header`, auf die gleiche Weise wie bei `Query`, `Path` und `Cookie`.

# リクエストフォームとファイル

`File`と`Form`を同時に使うことでファイルとフォームフィールドを定義することができます。

/// info | 情報

アップロードされたファイルやフォームデータを受信するには、まず<a href="https://andrew-d.github.io/python-multipart/" class="external-link" target="_blank">`python-multipart`</a>をインストールします。

例えば、`pip install python-multipart`のように。
