Entity Framework Scaffold-DbContext 用戶登錄失敗

Question

我正在嘗試使用 Visual Studio 2017 和帶有 Entity Framework Core 的 .NET Core 2 構建一個 API。 我正在按照此鏈接中的說明進行操作。 我在標題為：逆向工程你的 model 的部分

他們給出的運行命令如下：

Scaffold-DbContext "Server=(localdb)\mssqllocaldb;Database=Blogging;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models

我的數據庫是 Azure SQL 數據庫，因此我嘗試使用 Azure 門戶提供的連接字符串運行此命令：

Scaffold-DbContext "Server=tcp:dbname.database.windows.net,1433;Initial Catalog=DBNAME_DB;Persist Security Info=False;User ID=username;Password=password;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models

我被退回了

從同一台機器和用戶名和密碼，我可以使用 SSMS 登錄到數據庫。 有沒有人對我無法從 Visual Studio 運行此命令有任何建議？

Answer 1

我想出了我的問題。 我的密碼包含字符 $，需要在 $ 之前使用 ` 將其轉義。

Answer 2

將雙引號 " 更改為單引號 ' 不必單獨添加轉義字符，它也適用於其余參數。

Scaffold-DbContext 'Server=tcp:dbname.database.windows.net,1433;Initial Catalog=DBNAME_DB;Persist Security Info=False;User ID=username;Password=password;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;' Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models

Answer 3

您是否嘗試更新連接字符串的 web.config 文件。 這可能是不允許您登錄 azure 的原因。

Answer 4

請確保用戶登錄名存在於目標 SQL Azure 數據庫上，而不僅僅是存在於 Azure SQL 數據庫服務器上。

-- 在主數據庫上 CREATE LOGIN MaryLogin WITH PASSWORD = '';

-- 關於用戶數據庫

創建用戶 MaryUser 從登錄 MaryLogin;

創建在Azure門戶防火牆規則，以允許訪問SQL Azure的數據庫作為解釋在這里。 確保端口 TCP 1433 從您的計算機打開。

Answer 5

對我來說，以下命令在 Package 管理器控制台中執行時有效：PM>

Scaffold-DbContext "Server=.;Database=Employee;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models
