关于局部视图的另一个问题

问题描述

| 我觉得自己完全是个白痴，但对于我的一生，我无法弄清楚我在这里错过了什么。 我有以下几点：

 @section TopPane

{ @ * @ {Html.Action（\“ _ OpenIDSignInPartial \”，\“帐户\”）;} * @ @ {Html.RenderAction（\“ _ OpenIDSignInPartial \”，\“帐户\”）;} 使用您的mysite.com帐户登录或注册一个帐户 @ {Html.RenderPartial（\“ _ LoginPartial \”）;} @ {Html.RenderPartial（\“ _ RegisterPartial \”）;} } 如您所见，我正在渲染3个局部视图。 现在为控制器代码----

public class AccountController : Controller
{
    private readonly IAuthenticationService _authenticationService;
    OpenIdRelyingParty _openIdRelyingParty = new OpenIdRelyingParty(null);
    public AccountController(IAuthenticationService authenticationService)
    {
        _authenticationService = authenticationService;
    }

    public ActionResult Index()
    {
        return View();
    }
    public ActionResult SignIn()
    {
        return View();
    }
    [HttpPost]
    public ActionResult SignIn(AccountSignInviewmodel accountSignInviewmodel)
    {
        return View();
    }
    public ActionResult OpenIdSignIn()
    {
         AccountIndexviewmodel accountIndexviewmodel = new AccountIndexviewmodel();
        IAuthenticationResponse authenticationResponse = _openIdRelyingParty.GetResponse();
         switch (authenticationResponse.Status)
         {
             case AuthenticationStatus.Authenticated:
                 try
                 {
                     var claimedIdentifier = authenticationResponse.ClaimedIdentifier.ToString();
                     _authenticationService.OpenIdSignIn(claimedIdentifier);
                 }
                 catch (Exception)
                 {
                     // Do something with this man!
                     throw;
                 }
                 break;
             case AuthenticationStatus.Canceled:
                 accountIndexviewmodel.openIdSignInviewmodel.ErrorMessage = \"An Error Message\";
                 break;
         }
         return View(\"SignIn\",accountIndexviewmodel); // ALWAYS an ERROR
    }
    [HttpPost]
    public ActionResult OpenIdSignIn(AccountOpenIdSignInviewmodel accountOpenIdSignInviewmodel)
    {
        IAuthenticationResponse authenticationResponse = _openIdRelyingParty.GetResponse();
        if (authenticationResponse == null)
        {
            Identifier identifier;
            if (Identifier.TryParse(accountOpenIdSignInviewmodel.openid_identifier,out identifier))
            {
                try
                {
                    IAuthenticationRequest request =
                        _openIdRelyingParty.CreateRequest(accountOpenIdSignInviewmodel.openid_identifier);

                    return request.RedirectingResponse.AsActionResult();
                }
                catch (ProtocolException protocolException) // Prolly should add some errors to the model
                {
                    ModelState.AddModelError(\"openid_identifier\",\"Unable to authenticate\");
                    return View(\"SignIn\");
                }
            }
        }
        return View();
    }
    public ActionResult _OpenIDSignInPartial(AccountOpenIdSignInviewmodel accountOpenIdSignInviewmodel)
    {
        return PartialView(\"_OpenIdSignInPartial\");
    }
}

当我从OpenIdSignIn ActionResult（）遍历视图时，出现以下错误 传递到字典中的模型项的类型为\'Web.viewmodels.AccountIndexviewmodel \'，但是此字典要求使用模型项'\ Web.viewmodels.AccountSignInviewmodel \'。 好的，好的，我将返回一个AccountSignInviewmodel对吗？然后我收到一条错误消息，说它需要AccountIndexviewmodel ...在这里接22。     

解决方法

        您正在向主视图返回

AccountIndexViewModel

。这意味着必须将2个偏词强类型化为

AccountIndexViewModel

： _LoginPartial _RegisterPartial 如果不是，则在渲染它们时需要传递正确的视图模型。 就

_OpenIDSignInPartial

而言，您是通过

_OpenIDSignInPartial

动作将其渲染的

return PartialView(\"_OpenIdSignInPartial\");

根据错误消息，看起来ѭ7是强类型为ѭ8：

@model AccountSignInViewModel

因此，请确保在返回部分视图时传递此模型的实例：

AccountSignInViewModel signInViewModel = ...
return PartialView(\"_OpenIdSignInPartial\",signInViewModel);
