Exemple : Créer un plug-in personnalisé pour utiliser l’API Google Maps pour votre fournisseur de données géospatiales
Vous pouvez utiliser un plug-in personnalisé pour utiliser des données géospatiales d’un fournisseur de données de votre choix au lieu d’utiliser l’API Bing Maps par défaut dans Field Service et Project Service.
L’exemple est disponible ici : Plug-in personnalisé pour utiliser l’API Google Maps comme fournisseur de données géospatiales (Dynamics 365)
Configuration requise
Une connexion Internet est requise pour télécharger l’exemple de projet et restaurer les packages NuGet utilisés dans l’exemple de projet.
Conditions préalables
La solution Dynamics 365 Field Service doit être installée sur votre instance Dynamics 365 (online). Informations complémentaires : Installer et configurer Field Service
Fournissez votre propre clé d’API Google dans le fichier GoogleDataContracts.cs de l’exemple :
public const string GoogleApiKey = "<PROVIDE YOUR GOOGLE API KEY";
Montre ce qui suit
Cet exemple illustre comment créer un plug-in personnalisé pour les actions msdyn_GeocodeAddress et msdyn_RetrieveDistanceMatrix dans Universal Resource Scheduling pour utiliser l’API Google Maps pour les données géospatiales au lieu d’utiliser l’API Bing Maps par défaut.
Exécuter l’exemple
Cet exemple génère un fichier d’assembly de plug-in : CustomPlugin-FS-Geospatial.dll.
- Téléchargez ou clonez les exemples de référentiel.
- Accédez à l’emplacement où vous avez téléchargé ou cloné le référentiel sur votre ordinateur, accédez au dossier field-service/CustomPlugin-FS-Geospatial et double-cliquez sur le fichier CustomPlugin-FS-Geospatial.sln pour ouvrir la solution dans Visual Studio.
- Dans Visual Studio, sélectionnez Build>Générer la solution. Les packages NuGet utilisés dans la solution se téléchargent automatiquement si l’option de restaurer les packages NuGet automatiquement lors de la génération d’un projet est activée dans Visual Studio. Pour plus d’informations : Activation et désactivation de la restauration des packages
Après l’exécution de l’exemple
Après avoir exécuté avec succès (généré) l’exemple, un fichier d’assembly de plug-in personnalisé, CustomPlugin-FS-Geospatial.dll, devient disponible dans le dossier <Project>\bin\debug. Inscrivez l’exemple d’assembly de plug-in personnalisé sur votre instance Dynamics 365 (online) pour pouvoir utiliser le plug-in pour utiliser l’API Google Maps au lieu de l’API Bing Cartes par défaut.
