Beispiel: Benutzerdefiniertes Plug-In zur Nutzung der Google Maps-API als räumliche Datenanbieter erstellen
Sie können ein angepasstes Plug-In verwenden, um geospatiale Daten aus einem Datenanbieter Ihrer Wahl verwenden, anstatt die standardmäßige Bing Maps API im Field Service und Project Service zu verwenden.
Beispiel hier verfügbar: Benutzerdefiniertes Plug-In, um die Google Maps-API als geospatialen Datenanbieter zu verwenden (Dynamics 365)
Voraussetzungen
Um das Beispielprojekt herunterzuladen und die NuGet-Pakete wiederherzustellen, die im Beispielprojekt verwendet werden, ist eine Internetverbindung erforderlich.
Anforderungen
Dynamics 365 Field Service-Lösung muss auf der Dynamics 365 (online)-Instanz installiert werden. Weitere Informationen: Installieren Sie den Field Service und richten Sie ihn ein
Erstellen Sie einen eigenen Google-API-Schlüssel in der Datei GoogleDataContracts.cs im Beispiel:
public const string GoogleApiKey = "<PROVIDE YOUR GOOGLE API KEY";
Demonstriert
Dieses Beispiel veranschaulicht, wie ein benutzerdefiniertes Plug-In für die Aktionen msdyn_GeocodeAddress und msdyn_RetrieveDistanceMatrix in Universal Resource Scheduling zur Nutzung der Google Maps-API für geospatiale Daten anstelle der standardmäßigen Bing Maps-API verwendet wird.
Ausführen des Beispiels
In diesem Beispiel wird eine Plug-In Assembly-Datei erstellt: CustomPlugin-FS-Geospatial.dll.
- Laden Sie das herunter oder klonen Sie es Proben Repo.
- Navigieren Sie zu dem Speicherort, an den Sie das Repository auf Ihren Computer heruntergeladen oder geklont haben, und wechseln Sie zum Ordner Field Service/CustomPlugin-FS-Geospatial. Doppelklicken Sie auf die Datei CustomPlugin-FS-Geospatial.sln, um die Lösung in Visual Studio zu öffnen.
- Wählen Sie in Visual Studio Build>Build-Lösung aus. Die NuGet-Pakete, die in der Lösung verwendet werden, werden automatisch heruntergeladen, wenn die Option, NuGet-Pakete automatisch beim Erstellen eines Projekts wiederherzustellen, in Visual Studio aktiviert ist. Weitere Informationen: Aktivieren und Deaktivieren von NuGet-Paketwiederherstellung
Nachdem das Beispiel ausgeführt wurde
Nach der erfolgreichen Ausführung (Erstellung) des Beispiels wird eine benutzerdefinierte Plug-In Assembly-Datei CustomPlugin-FS-Geospatial.dll im Ordner <Project>\bin\debug zur Verfügung gestellt. Registrieren Sie die benutzerdefinierte Beispiel-Plug-In-Assembly auf Ihrer Instanz Dynamics 365 (online), um das Plug-In zur Nutzung der Google Maps-API anstelle der Standard Bing Maps-API verwenden zu können. Weitere Informationen siehe Registrieren und Bereitstellen von Plug-ins.
