Question

在ASP Web API中，我使用个人帐户注册用户。我在这个官方教程之后实现了这个功能：

现在我希望能够为用户分配一个角色：何时执行Register方法我想传递POST请求中的角色：

{
   "UserName": "Alice",
   "Password": "password123",
   "ConfirmPassword": "password123",
   "Role": "admin"                  -> i want add this
}

并且Register方法必须正确评估数据库的表。如何处理web api个人帐户中的角色？有什么教程吗？

在创建用户和相应角色

后，只需在代码中添加以下行

var roleresult = UserManager.AddToRole(currentUser.Id, "RoleName");

您还应该将角色属性添加到您的视图模型（通常称为 RegisterBindingModel ），该属性将传递给注册方法。

以下是注册方法的完整示例（ RoleEntity 和 UserEntity 是我在相应类中的实现身份，但这也适用于您的自定义实现）

public async Task<IdentityResult> RegisterAsync(RegisterViewModel model)
{
    var user = new UserEntity { UserName = model.UserName };
    var role = model.Role.ToString();

    if (await _roleManager.FindByNameAsync(role) == null)
    {
        var roleResult = await _roleManager.CreateAsync(new RoleEntity(role));

        if (roleResult != IdentityResult.Success)
        {
            return roleResult;
        }
    }

    var result = await _userManager.CreateAsync(user, model.Password);

    if (!result.Succeeded)
    {
        return result;
    }

    var addToRoleResult = await _userManager.AddToRoleAsync(user.Id, role);

    return !addToRoleResult.Succeeded ? addToRoleResult : IdentityResult.Success;
}

我的 RegisterViewModel 看起来像这样

public class RegisterViewModel
{
    [Required(ErrorMessage="This field is required")]
    [Display(Name = "User name", Prompt="Please enter user name...")]
    public string UserName { get; set; }

    [Required(ErrorMessage = "This field is required")]
    [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
    [DataType(DataType.Password)]
    [Display(Name = "Password", Prompt="Please enter password...")]
    public string Password { get; set; }

    [DataType(DataType.Password)]
    [Display(Name = "Confirm password", Prompt = "Please enter confirm password...")]
    [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
    public string ConfirmPassword { get; set; }

    [Required(ErrorMessage = "This field is required")]
    [Display(Name = "Role")]
    public Roles Role { get; set; }
}
