範例：建立要使用 Google Maps API 做為地理空間資料提供者的外掛程式
您可以透過自訂外掛程式使用您所選擇資料提供者提供的地理空間資料，而不透過 Field Service 和 Project Service 中的預設 Bing 地圖服務 API 來使用。
範例可在這裡找到：可使用 Google Maps API 做為地理空間資料提供者的自訂外掛程式 (Dynamics 365)
先決條件
須有網際網路連線才能下載範例專案及還原範例專案中使用的 NuGet 套件。
需求
Dynamics 365 Field Service 解決方案必須已安裝在 Dynamics 365 (online) 執行個體上。 其他資訊：安裝和設定 Field Service
在範例的 GoogleDataContracts.cs 檔案中提供您自己的 Google API 金鑰：
public const string GoogleApiKey = "<PROVIDE YOUR GOOGLE API KEY";
示範
此範例顯示如何在 Universal Resource Scheduling 中建立 msdyn_GeocodeAddress 和 msdyn_RetrieveDistanceMatrix 動作的自訂外掛程式，以使用 Google Maps API 存取地理空間資料，而不使用預設 Bing 地圖服務 API 來存取。
執行範例
此範例會產生外掛程式組件：CustomPlugin-FS-Geospatial.dll。
- 下載或複製範例存放庫。
- 瀏覽至電腦中下載或複製所到存放庫的位置、移至 field-service/CustomPlugin-FS-Geospatial 資料夾，然後按兩下 CustomPlugin-FS-Geospatial.sln 檔案以在 Visual Studio 中開啟此解決方案。
- 在 Visual Studio 中，選取建置>建置方案。 如果 Visual Studio已啟用要在建置專案時自動還原 NuGet 套件的選項，將會自動下載解決方案中使用的 NuGet 套件。 其他資訊：啟用和停用套件還原
執行範例之後
成功執行 (建置) 範例之後，<Project>\bin\debug 資料夾就會有自訂外掛程式組件檔案 CustomPlugin-FS-Geospatial.dll 可供使用。 在 Dynamics 365 (online) 執行個體上註冊範例自訂外掛程式組件，才可以透過外掛程式使用 Google Maps API，而不使用預設 Bing 地圖服務 API。 其他資訊：註冊和部署自訂外掛程式
