# Paramètres de requête

Quand vous déclarez des paramètres dans votre fonction de chemin qui ne font pas partie des paramètres indiqués dans le chemin associé, ces paramètres sont automatiquement considérés comme des paramètres de "requête".

{* ../../docs_src/query_params/tutorial001.py hl[9] *}

La partie appelée requête (ou **query**) dans une URL est l'ensemble des paires clés-valeurs placées après le `?` , séparées par des `&`.

Par exemple, dans l'URL :

def test_no_body_status_code_exception_handlers():
    response = client.get("/http-no-body-statuscode-exception")
    assert response.status_code == 204
    assert not response.content
