登录后mvc重定向不起作用

我有一个名为Auth的mvc控制器,以及一个名为login的操作,看起来像这样..

    [HttpPost]
    public async Task<ActionResult> LogIn(LogInModel model)
    {
if (!ModelState.IsValid)
{
return View();
}

var user = await userManager.FindAsync(model.Email, model.Password);

if (user != null)
{
await SignIn(user);
if (!string.IsNullOrWhiteSpace(model.ReturnUrl))
{
 return Redirect(GetRedirectUrl(model.ReturnUrl));
}
else
{
//return RedirectToAction("Index", "Home");
return Redirect("../Home/Index");
}
}
else
{
return View();
}

// user authN failed
//ModelState.AddModelError("", "Invalid email or password");
//return View();
}

但是我没有重定向到我的../Home/Index。即使我成功登录,我也会待在同一页面上。这可能有什么问题?

您使用的是什么版本的MVC?我使用以下方法保护过去使用登录的页面,并检查属于asp.net Identitiy的枚举,因为您可以看到返回URL被传递给方法。

    private ActionResult RedirectToLocal(string returnUrl)
    {
        if (Url.IsLocalUrl(returnUrl))
        {
            return Redirect(returnUrl);
        }
        return RedirectToAction("Index", "Home");
    }

//
    // POST: /Account/Login
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
    {
        if (!ModelState.IsValid)
        {
            return View(model);
        }

        // This doesn't count login failures towards account lockout
        // To enable password failures to trigger account lockout, change to shouldLockout: true
        var result = await SignInManager.PasswordSignInAsync(model.Username, model.Password, model.RememberMe, shouldLockout: false);

        switch (result)
        {
            case SignInStatus.Success:
                return RedirectToLocal(returnUrl);
            case SignInStatus.LockedOut:
                return View("Lockout");
            case SignInStatus.RequiresVerification:
                return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
            case SignInStatus.Failure:
            default:
                ModelState.AddModelError("", "Invalid login attempt.");
                return View(model);
        }
    }

如果您使用的是MVC 4,则可以使用[AllowAnonymous]

在方法调用更改为Ajax之后,出现了相同的问题。只需将响应类型更改为JavaScript并要求其执行导航,因为调用结果是在Javscript代码块内处理的

var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);
switch (result)
{
  case SignInStatus.Success:

      var returnUrlJs = string.Format("location.href='{0}'", returnUrl);
      return new JavaScriptResult() { Script = returnUrlJs };
