我正在尝试使用身份创建授权。
到目前为止,eveything正在使用我在网上找到的指导。
但是我想修改角色的保存。我创建了一个枚举,我将这个枚举保存到aspNetRoles表中(代码如下)。
将角色保存到用户的方式如下:
UserManager.AddToRole(user.Id, "Admin");
我不喜欢作为第二个参数发送字符串并希望发送枚举。
这可能吗?
到目前为止我的代码:
通过添加自定义属性修改aspnetRoles表:
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base("DefaultConnection", throwIfV1Schema: false)
{
}
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
new public DbSet<ApplicationRole> Roles { get; set; }
}
public class ApplicationRole : IdentityRole
{
[Required]
public RoleId roleId { get; set; }
}
public enum RoleId
{
Developer = 0,
Administrator = 1,
Other = 2
}
在startup.cs中添加角色:
if (!roleManager.RoleExists("Developer"))
{
// first we create Admin rool
var role = new ApplicationRole();
role.Name = "Developer";
role.roleId = RoleId.Developer;
roleManager.Create(role);
//Here we create a Admin super user who will maintain the website
var user = new ApplicationUser();
user.UserName = "ra3iden";
user.Email = "Email@gmail.com";
user.FirstName = "Myname";
user.LastName = "LastName";
string userPWD = "A@Z200711";
var chkUser = UserManager.Create(user, userPWD);
//Add default User to Role Admin
if (chkUser.Succeeded)
{
var result1 = UserManager.AddToRole(user.Id, "Developer");
}
}
正如我上面提到的,我不希望拥有rolename属性,我想使用枚举,这是怎么做的?

public enum Roles

Developer,
Manager
}
if (!roleManager.RoleExists(Roles.Developer))
{
// first we create Admin rool
var role = new ApplicationRole();
role.Name = Roles.Developer;
role.roleId = RoleId.Developer;
roleManager.Create(role);
//Here we create a Admin super user who will maintain the website
var user = new ApplicationUser();
user.UserName = "ra3iden";
user.Email = "Email@gmail.com";
user.FirstName = "Myname";
user.LastName = "LastName";
string userPWD = "A@Z200711";
var chkUser = UserManager.Create(user, userPWD);
//Add default User to Role Admin
if (chkUser.Succeeded)
{
var result1 = UserManager.AddToRole(user.Id, Roles.developer);
}
}

UserManager.AddToRole
是extension method,因此您可以编写类似的方法将您的用户添加到您的角色中:
public static IdentityResult AddToRole<TUser, TKey>(
this UserManager<TUser, TKey> manager,
TKey userId,
RoleId role
)
where TUser : class, Object, IUser<TKey>
where TKey : Object, IEquatable<TKey>
{
return manager.AddToRoleAsync(userId, role.ToString())
.Result;
}
但也许这种情况需要采用不同的方法。 "Admin"
不是魔法常数,但它是常数。如果您想将"Admin"
重命名为"Administrator"
,该怎么办?字符串常量重命名很难操作,可能存在错误。
您可以做的是为您的角色声明命名常量:
public static class Role
{
public const string Admin = "Admin";
public const string Developer = "Developer";
public const string Other = "Other";
}
. . .
UserManager.AddToRole(user.Id, Role.Admin);
