Beispiel: Schreiben der Eigenschaften aller Services in eine CSV-Datei
In diesem Beispielskript wird die ArcGIS-REST-API zum Lesen ausgewählter Eigenschaften aller Services und Schreiben dieser Eigenschaften in eine Datei mit kommagetrennten Werten (CSV) verwendet. Das Skript enthält relativ viele Codezeilen, da es viele verschiedene Service-Typen verarbeiten muss.
Mit diesem Skript können Sie einen schreibgeschützten Bericht zu Service-Eigenschaften erstellen, der mit einem Tabellenkalkulationsprogramm wie Microsoft Excel angezeigt werden kann.
Detailinformationen:
Wenn Sie mehrere Service-Eigenschaften mithilfe einer Kalkulationstabelle gleichzeitig bearbeiten möchten, sollten Sie ein anderes Skript schreiben, mit dem Werte aus der CSV-Datei abgerufen und als Änderungen auf den Service angewendet werden können. Informationen dazu finden Sie unter Beispiel: Bearbeiten von Service-Eigenschaften.
