예제

다음 예제에서는 AuthorizationContext 값을 사용하여 인증을 사용자 지정하는 AuthorizationAttribute 구현을 보여 줍니다.

Public Class RestrictAccessToAssignedManagers
    Inherits AuthorizationAttribute

    Protected Overrides Function IsAuthorized(ByVal principal As System.Security.Principal.IPrincipal, ByVal authorizationContext As System.ComponentModel.DataAnnotations.AuthorizationContext) As System.ComponentModel.DataAnnotations.AuthorizationResult
        Dim eph As EmployeePayHistory
        Dim selectedEmployee As Employee
        Dim authenticatedUser As Employee

        eph = CType(authorizationContext.Instance, EmployeePayHistory)
            
        Using context As New AdventureWorksEntities()
            selectedEmployee = context.Employees.SingleOrDefault(Function(e) e.EmployeeID = eph.EmployeeID)
            authenticatedUser = context.Employees.SingleOrDefault(Function(e) e.LoginID = principal.Identity.Name)
        End Using

        If (selectedEmployee.ManagerID = authenticatedUser.EmployeeID) Then
            Return AuthorizationResult.Allowed
        Else
            Return New AuthorizationResult("Only the authenticated manager for the employee can add a new record.")
        End If
    End Function
End Class

public class RestrictAccessToAssignedManagers : AuthorizationAttribute

        }

        if (selectedEmployee.ManagerID == authenticatedUser.EmployeeID)

            return AuthorizationResult.Allowed;
        }
