Web API-Abfragedatenbeispiele (clientseitiges JavaScript)
Dieses Beispiel veranschaulicht, wie grundlegende Abfragen mit der Web-API von Dynamics 365 for Customer Engagement unter Verwendung von Client-seitigem JavaScript durchgeführt werden können.
Notiz
Dieses Beispiel implementiert die Vorgänge, die unter Web API-Abfragedatenbeispiel beschrieben sind, und nutzt bekannte clientseitige JavaScript-Konstrukte, die unter Web-API-Beispiele (clientseitiges JavaScript) beschrieben sind.
Anforderungen
Dies ist erforderlich, um das Beispiel auszuführen:
Zugriff auf Customer Engagement online oder lokal in Version 8.0 oder höher.
Ein Benutzerkonto mit Rechten zum Import von Lösungen und zur Durchführung von CRUD-Vorgängen (normalerweise eine "Systemadministrator" oder "Systemanpasser" Sicherheitsrolle).
Beispiel ausführen
Um dieses Beispiel auszuführen, gehen Sie zu Microsoft CRM Web API Query Data Sample (Client-side JavaScript) und laden Sie die Archivdatei mit dem Beispiel herunter: Microsoft CRM Web API Query Data Sample (Client-side JavaScript).zip. Extrahieren Sie die Inhalte des Beispiels, und suchen Sie die Datei für die verwaltete WebAPIQueryData_1_0_0_0_managed.zip-Lösung. Importieren Sie die verwaltete Lösung in Ihre Customer Engagement Organisation und führen Sie das Beispiel aus. Anweisungen zum Importieren der Beispiellösung finden Sie unter Web-API-Beispiele (clientseitiges JavaScript)
