实体框架Scaffold-DbContext用户登录失败

Question

我正在尝试使用Visual Studio 2017和带有Entity Framework Core的.NET Core 2构建API.我按照此链接的指示.我在标题为:逆向工程模型的部分

他们给出的命令如下:

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

我的数据库是Azure SQL数据库,因此我尝试使用Azure门户提供的连接字符串运行此命令:

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

我回来了

Login failed for user 'username'.

从这台机器和用户名和密码,我可以使用SSMS登录数据库.有没有人有任何建议我无法从Visual Studio运行此命令？

Answer 1

我想出了我的问题.我的密码包含字符$,这需要通过在$之前使用`来转义.

Answer 2

将双引号 " 更改为单引号 ' 无需单独添加转义字符，它也适用于其余参数。

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
