Verbinden mit Strategy Verwendung eines Workstation-Identitätstokens

Der mstrio-py Die Python-Bibliothek bietet eine Verbindungsmodul, um eine Sitzung mit dem Intelligence Server zu starten. Er unterstützt die Standard- und LDAP-Authentifizierungsmodi.

Um die Sitzung zu starten, müssen Sie die URL zu einfügen Strategy REST-API-Server, Projekt-ID, Benutzername und Kennwort.

Kopieren

from mstrio.connection import Connection

base_url = "https://your-microstrategy-server.com/MicroStrategyLibrary/api"
mstr_username = "Username"
mstr_password = "Password"
project_id = "PROJECT_ID"
conn = Connection(base_url, mstr_username, mstr_password, project_id=project_id)

In Workstation ausgeführte Skripts können geändert werden, um auf die globale Variable zuzugreifen workstationData und das Identitätstoken der Umgebung verwenden, in dem es aktuell gespeichert ist. Wenn die Sitzung auf diese Weise initiiert wird, müssen Benutzer die URL zu nicht mehr einfügen Strategy REST-API-Server und ihre Anmeldeinformationen in das Skript.
