ASP.NET MVC登录RETURNURL始终是NULL？ [英] ASP.NET MVC Login ReturnUrl always NULL?

问题描述

在ASP.NET MVC使用窗体身份验证尝试重新登录一个网站时，它把一个RETURNURL参数查询字符串。我的登录操作方法接受一个RETURNURL字符串。然而，似乎RETURNURL串总是空，即使当它显然是在查询字符串。为什么这可能是这样或可能的修复有什么想法？

Using Forms Authentication in ASP.NET MVC when trying to log back into a site, it puts a ReturnUrl parameter in the query string. My Logon action method accepts a "returnUrl" string. However it seems that returnUrl string is always null, even when it is clearly in the query string. Any thoughts on why this might be the case or a possible fix?

推荐答案

也许你不包括 RETURNURL 参数为你登录表单的action属性，从而张贴到URL没有这个参数？

Maybe you don't include the ReturnURL parameter into you login form's action attribute, thus posting to a URL without that parameter?
