为什么微软自己的MVC3模板不遵循胖模型，瘦控制器？

Question

来自微软自己的MVC3

内置模板

模型非常瘦小，基本上没有代码。

模型

public class RegisterModel
{
    [Required]
    [Display(Name = "User name")]
    public string UserName { get; set; }

    [Required]
    [DataType(DataType.EmailAddress)]
    [Display(Name = "Email address")]
    public string Email { get; set; }

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

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

另一方面，当控制器看起来很胖的时候，做更简单的路由.

控制器

[HttpPost]
[AllowAnonymous]
public ActionResult Register(RegisterModel model)
{
    if (ModelState.IsValid)
    {
        // Attempt to register the user
        MembershipCreateStatus createStatus;
        Membership.CreateUser(model.UserName, model.Password, model.Email, null, null, true, null, out createStatus);

        if (createStatus == MembershipCreateStatus.Success)
        {
            FormsAuthentication.SetAuthCookie(model.UserName, false /* createPersistentCookie */);
            return RedirectToAction("Index", "Home");
        }
        else
        {
            ModelState.AddModelError("", ErrorCodeToString(createStatus));
        }
    }

    // If we got this far, something failed, redisplay form
    return View(model);
}

Answer 1

控制器在那里所做的一切都是它的工作，它是相当基本的东西。不会为您生成业务逻辑。当您将有用的功能封装到模型中时，模型就会变胖；您不能期望从模板中看到这一点。

Answer 2

我很好奇你怎么认为控制器可以节食？老实说，我看不到任何东西可以在不违反SRP的情况下移动到模型上。
