Eksempel: Oprette brugerdefineret plug-in, der bruger Google Maps-API som geospatial dataprovider

Du kan bruge en brugerdefineret plug-in, hvis du vil bruge geospatiale data fra en dataprovider af efter eget valg i stedet for at bruge standard Bing Kort-API i Field Service og Project Service.

Eksemplet er tilgængeligt her: Brugerdefineret plug-in, der bruger Google Maps API som geospatial dataprovider (Dynamics 365)

Forudsætninger

Der kræves internetforbindelse til hentning af eksempelprojektet og gendannelse af de NuGet-pakker, der bruges i eksempelprojektet.

Krav

  • Dynamics 365 Field Service-løsningen, der skal være installeret på din Dynamics 365 (online)-forekomst. Flere oplysninger: Installere og konfigurere Field Service

  • Brug din egen Google-API-nøgle i filen GoogleDataContracts.cs i eksemplet:

    public const string GoogleApiKey = "<PROVIDE YOUR GOOGLE API KEY";

Demonstrerer

Dette eksempel viser, hvordan du kan oprette en brugerdefineret plug-in til msdyn_GeocodeAddress og msdyn_RetrieveDistanceMatrix-handlingerne i Universal Resource Scheduling, der bruger Google Maps API til geospatiale data i stedet for at bruge standard Bing Kort API'en.

Kør eksemplet

I dette eksempel oprettes der en plug-in-assembly-fil: CustomPlugin-FS-Geospatial.dll.

  1. Download eller klon eksempelkopien.
  2. Naviger til den placering, hvor du hentede eller klonede lageret på computeren, gå til mappen field-service/CustomPlugin-FS-Geospatial, og dobbeltklik på filen CustomPlugin-FS-Geospatial.sln for at åbne løsningen i Visual Studio.
  3. Vælg Opbyg>Opbyg løsning i Visual Studio. De NuGet-pakker, der bruges i løsningen, hentes automatisk, hvis muligheden for at gendanne NuGet-pakker automatisk under opbygning af et projekt i Visual Studio er aktiveret. Flere oplysninger: Aktivering og deaktivering af gendannelse af pakker

Når du har kørt eksemplet

Når du har kørt (opbygget) eksemplet, bliver en brugerdefineret plug-in-assembly-fil, CustomPlugin-FS-Geospatial.dll, tilgængelig i mappen <Project>\bin\debug. Registrer eksemplet på den brugerdefinerede plug-in-assembly på din Dynamics 365 (online) forekomst for at kunne bruge plug-in'en til at bruge Google Maps API'en i stedet for Bing Kort-standard-API'en. Flere oplysninger: Registrere og installere din brugerdefinerede plug-in.
