我想從我的SQL Server數據庫在Windows Server 2008 R2上運行的SQL Server數據庫中獲取一些JSON對象返回的行，但我收到了500內部服務器錯誤，任何人都可以請幫助我解決這個問題？以下是一些更多信息。無法通過http GETrequest訪問SQL Server數據庫
開發環境：WebMartrix 2
代碼：
@{
var result = MyDataBase.GetData();
Response.ContentType = "application/json";
Json.Write(result, Response.Output);
}
這裏是響應錯誤消息：
警告：你已經包括此頁面上的谷歌地圖API多次。這可能會導致意外的錯誤。
