Exemple : écrire des propriétés de tous les services dans un fichier CSV

Cet exemple de script utilise l’ArcGIS REST API pour lire les propriétés sélectionnées de tous vos services et les écrire dans un fichier CSV (à valeurs séparées par des virgules). Ce script comprend un nombre relativement élevé de lignes de code, car il doit traiter tous les différents types de service.

Ce script fournit un rapport en lecture seule des propriétés de service qui peut être consulté aisément dans un tableur tel que Microsoft Excel.

Approfondissement :

Si vous souhaitez mettre à jour des propriétés de service par lot en utilisant un tableur, vous pouvez rédiger un autre script afin de lire les valeurs du fichier CSV et de les appliquer au service sous la forme de modifications. Pour savoir comment procéder, consultez la rubrique Exemple : mise à jour des propriétés du service.

Remarque :

Pour exécuter le script pour les sites HTTPS (uniquement), vous devez remplacer le module HTTPConnection par HTTPSConnection partout où il apparaît dans le script et redéfinir le port sur le port 6443.

Remarque :

Si votre site ne possède pas un certificat en cours de validité, les demandes HTTPS contenues dans ce script renvoient l’erreur suivante : [SSL: CERTIFICATE_VERIFY_FAILED]. Pour éviter ce problème, vous pouvez désactiver la vérification du certificat SSL en insérant le code suivant en haut du script :

import ssl
try:
    _create_unverified_https_context = ssl._create_unverified_context
except AttributeError:
    # Legacy Python that doesn't verify HTTPS certificates by default
    pass
else:
    # Handle target environment that doesn't support HTTPS verification
    ssl._create_default_https_context = _create_unverified_https_context
