Découvrir les langues disponibles (version Advanced)

Ce document explique comment utiliser l'API Cloud Translation pour répertorier les langues disponibles à l'aide de Cloud Translation – Advanced.

Avant de commencer

Pour pouvoir utiliser l'API Cloud Translation, vous devez disposer d'un projet pour lequel l'API Cloud Translation est activée et qui est associé à des identifiants appropriés. Vous pouvez également installer des bibliothèques clientes pour les langages de programmation courants afin de faciliter les appels vers l'API.

Pour en savoir plus, consultez la page Configuration.

Envoyer une requête sur les langues disponibles

Pour découvrir les langues disponibles pour cette API, envoyez une requête HTTP à l'aide d'une URL au format suivant :

https://translation.googleapis.com/v3/projects/project-number-or-id/locations/location/supportedLanguages

Obtenir la liste des langues disponibles

API REST et ligne de commande

Pour obtenir la liste de toutes les langues disponibles, envoyez une requête GET à l'URL https://translation.googleapis.com/v3/projects/project-number-or-id/locations/location/supportedLanguages. Vous trouverez ci-dessous un exemple de requête GET effectuée avec curl et PowerShell. L'exemple se sert du jeton d'accès associé à un compte de service configuré pour le projet à l'aide du SDK Cloud de Google Cloud. Pour obtenir des instructions sur l'installation du SDK Cloud, la configuration d'un projet avec un compte de service et l'obtention d'un jeton d'accès, consultez la page Configuration.

Avant d'utiliser les données de requête ci-dessous, effectuez les remplacements suivants :

project-number-or-id par le numéro ou l'ID de votre projet Google Cloud

Méthode HTTP et URL :

GET https://translation.googleapis.com/v3/projects/project-number-or-id/locations/global/supportedLanguages

Pour envoyer votre requête, choisissez l'une des options suivantes :

curl

Exécutez la commande suivante :

curl -X GET \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
https://translation.googleapis.com/v3/projects/project-number-or-id/locations/global/supportedLanguages

PowerShell

Exécutez la commande suivante :

$cred = gcloud auth application-default print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
  -Method GET `
  -Headers $headers `
  -Uri "https://translation.googleapis.com/v3/projects/project-number-or-id/locations/global/supportedLanguages
" | Select-Object -Expand Content

Vous devriez recevoir une réponse JSON de ce type :

{
  "languages": [
     "languageCode": "af",
      "supportSource": true,
      "supportTarget": true
    },
    {
      "languageCode": "am",
      "supportSource": true,
      "supportTarget": true
    },
    {
      "languageCode": "ar",
      "supportSource": true,
      "supportTarget": true
    },
    ....
    {
      "languageCode": "zu",
      "supportSource": true,
      "supportTarget": true
    }
   ]
}

La liste est triée alphabétiquement par code de langue. Cette requête renvoie les codes de langue ISO-639-1 correspondant aux langues disponibles. Certains codes de langue incluent également un code pays, tel que zh-CN ou zh-TW. Exemple :

   {
      "languageCode": "zh-TW",
      "supportSource": true,
      "supportTarget": true
    },

C#

Répertorier les langues disponibles avec le nom écrit dans la langue cible

API REST et ligne de commande

Voici un autre exemple qui renvoie la liste des langues disponibles, avec les noms écrits dans la langue cible spécifiée. La liste renvoyée est triée par ordre alphabétique selon la langue cible.

Avant d'utiliser les données de requête ci-dessous, effectuez les remplacements suivants :

project-number-or-id par le numéro ou l'ID de votre projet Google Cloud

Méthode HTTP et URL :

GET https://translation.googleapis.com/v3/projects/project-number-or-id/locations/global/supportedLanguages?display_language_code=sq

Pour envoyer votre requête, choisissez l'une des options suivantes :

curl

Exécutez la commande suivante :

curl -X GET \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
https://translation.googleapis.com/v3/projects/project-number-or-id/locations/global/supportedLanguages?display_language_code=sq

PowerShell

Exécutez la commande suivante :

$cred = gcloud auth application-default print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
  -Method GET `
  -Headers $headers `
  -Uri "https://translation.googleapis.com/v3/projects/project-number-or-id/locations/global/supportedLanguages?display_language_code=sq
" | Select-Object -Expand Content

Vous devriez recevoir une réponse JSON de ce type :

{
  "languages": [{
      "languageCode": "af",
      "displayName": "Afrikanisht",
      "supportSource": true,
      "supportTarget": true
    },
    {
      "languageCode": "am",
      "displayName": "Amarikisht",
      "supportSource": true,
      "supportTarget": true
    },
    {
      "languageCode": "en",
      "displayName": "Anglisht",
      "supportSource": true,
      "supportTarget": true
    },
    ...{
      "languageCode": "zu",
      "displayName": "Zulu",
      "supportSource": true,
      "supportTarget": true
    }

	]
}

Dans ce cas, la requête renvoie les mêmes codes de langue que ci-dessus, ainsi que les chaînes name qui donnent les noms des langues écrits dans la langue cible. Dans cet exemple, la langue est l'albanais (sq).
