手动创建参数ReturnUrl
我有像“home/details/5”这样的视图，它可以由匿名用户访问。但有一个按钮，只有注册用户才能按下。没问题，我可以查看 Request.IsAuthenticated ，如果匿名，我会显示按钮登录而不是秘密按钮
，但问题是 - 当按登录时，我可能会丢失页面的地址和参数。如何创建登录按钮并传递参数 ReturnUrl ？就像
<%= Html.ActionLink("enter to buy", "LogOn", "Account", new { ReturnUrl = path to view with route value })%>
我只看到愚蠢的解决方案
<%= Html.ActionLink("enter to buy", "LogOn", "Account", new { ReturnUrl = "home/details/" + ViewContext.RouteData.Values["id"] })%>
，但我不喜欢对控制器的名称进行硬编码
i have view like 'home/details/5', it can be access by anonymous user. but there is button, which can be pressed only by registered users. no problem, i can look into Request.IsAuthenticated , and if anonymous i show button login instead of secret button
but the problem- when press login i can lose address and parameters of page. how can i create login button and pass a parameter ReturnUrl ? something like
<%= Html.ActionLink("enter to buy", "LogOn", "Account", new { ReturnUrl = path to view with route value })%>
i see only stupid solution
<%= Html.ActionLink("enter to buy", "LogOn", "Account", new { ReturnUrl = "home/details/" + ViewContext.RouteData.Values["id"] })%>
but i don't like to hard code names of controller
