所以我刚开始学习MVC,并想知道我是否应该在我的控制器中使用多个动作,或只是一个来实现一个简单的注册页面。

我应该做这样的事情(多重行动):

HTML(RegisterForm)

clickuid

控制器

    <form action="CheckRegistration" method="post">
       Username:
        <input type="text" name="username"/>
        <input type="submit" value="Login" />
    </form>

或者这(单一行动):

HTML(注册)

    public ActionResult RegisterForm()
    {
        return View();
    }
    public ActionResult CheckRegistration()
    {
        bool success = true;

        // Create User Object and populate it with form data
        User currentUser = new User();
        currentUser.Username = Request.Form["username"].Trim().ToString();

        // Validate Registration
        // code

        // Add user to database
        // code

        if (success)
        {
            return View("Login");
        }else
        {
            return View("RegistrationSuccess");
        }
    }

控制器

    <form action="Register" method="post">
       Username:
        <input type="text" name="username"/>
        <input type="submit" value="Login" />
    </form>

按照我想到的第一种方式,它有多个动作并将其分成多个步骤。

第二种方式使用一个动作,因此当第一次调用Register视图时,它不会将用户添加到数据库,因为验证失败并且只返回View()。

从专业角度来看哪种方式更好(更好),或者这两种方式都是不好的方式,并且有更好的方法。

您应该有一个简单的视图并在帖子中登录。

    // GET: /Account/Register
    [AllowAnonymous]
    public ActionResult Register()
    {
        return View();
    }

    //
    // POST: /Account/Register
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Register(RegisterViewModel model)
    {
        if (ModelState.IsValid)
        {
            var user = new ApplicationUser() { UserName = model.Email, Email = model.Email };
            IdentityResult result = await UserManager.CreateAsync(user, model.Password);
            if (result.Succeeded)
            {
                await SignInAsync(user, isPersistent: false);

                // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
                // Send an email with this link
                // string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
                // var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
                // await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>");

                return RedirectToAction("Index", "Home");
            }
            else
            {
                AddErrors(result);
            }
        }

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

您可以在MVC中使用同名方法。

1)声明第一个方法为 [HttpGet] 所以它将返回View和

2)将第二种方法声明为 [HttpPost]

[HttpGet]
public ActionResult RegisterForm()
{
    return View();
}

[HttpPost]
public ActionResult RegisterForm()
{
    bool success = true;
    String otherData = ""

    // Create User Object and populate it with form data
    User currentUser = new User();
    currentUser.Username = Request.Form["username"].Trim().ToString();

    // Validate Registration
    // code

    // Add user to database
    // code

    if (success)
    {
        return RedirectToAction("RegisterSuccess");
    }else
    {
        return View("RegisterForm");
    }
}
