ASP.NET MVC自定义验证Authorize Attribute

前几天Insus.NET有在数据库实现过对某一字段进行加密码与解密《

 

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[usp_Users_VeryLoginVerify]
(
    @U_nbr NVARCHAR(20),
    @pwd NVARCHAR(100)
)
AS
BEGIN    
    DECLARE @errmsg NVARCHAR(50) = N'用户名或密码错误。'

    IF NOT EXISTS(SELECT TOP 1 1 FROM [dbo].[Users] WHERE [U_nbr] = @U_nbr)
    BEGIN    
        RAISERROR(@errmsg,16,1)
        RETURN
    END
        
    SELECT [U_nbr] AS [Account] FROM [dbo].[Users] WHERE [U_nbr] = @U_nbr AND CONVERT(NVARCHAR(100),DECRYPTBYPASSPHRASE('insus#sec!%y',[Pwd]))  = @pwd  

    IF @@ROWCOUNT <= 0
    BEGIN    
        RAISERROR(@errmsg,16,1)
        RETURN
    END
END
