用户可以单击登录超链接吗?

你的问题不是很清楚,但如果我能正确理解你,你在寻找 returnUrl 查询参数。例如,如果要将用户发送到 /foo

<a href="/login?returnUrl=/foo">Go to Foo, but login first</a>

这个问题还不清楚,但我会尝试:

在你的 Account

[Authorized] //actually you don't need this attribute here when have it on controller level
//All this action does is authenticating the user and redirecting to home/Index
public ActionResult AutoLogin()
{
  return RedirectToAction("Index", "Home");
}

然后在布局中添加:

@Html.ActionLink(
       "Login", "AutoLogin", "Account", routeValues: new{}, htmlAttributes: new {id = "loginLink"})
