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 Tabelle 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.

Hinweis:

Wenn Sie das Skript für Sites des Typs "(Nur) HTTPS" ausführen möchten, müssen Sie das Modul HTTPConnection überall im Skript auf HTTPSConnection aktualisieren und den Port zu 6443 ändern.

Hinweis:

Ist für die Site kein gültiges Zertifikat vorhanden, wird für die HTTPS-Anforderungen in diesem Skript der folgende Fehler zurückgegeben: [SSL: CERTIFICATE_VERIFY_FAILED]. Um diese Fehler zu umgehen, können Sie die SSL-Zertifikatüberprüfung deaktivieren. Fügen Sie dazu am Anfang des Skripts folgenden Code ein:

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
