【问题描述】：
我会尽量简单地解释我的问题。 我无法返回原始 URL，这要归功于它的 ReturnUrl。
这是我启动应用程序时所拥有的：
https://localhost:XXXX/Identity/Account/Login?ReturnUrl=%2F%3FGB%3DMjI2fC0x
到目前为止，一切都很好。
然后，一旦我使用我的帐户登录，我就会进入索引页面。
https://localhost:XXXX/?GB=MjI2fC0x
再次，一切都很好。
但是当我退出时，我会来到这个：
https://localhost:XXXX/Identity/Account/Logout
我怎样才能使网址成为this？
https://localhost:XXXX/Identity/Account/Logout?ReturnUrl=%2F%3FGB%3DMjI2fC0x
或者这个：
https://localhost:XXXX/Identity/Account/Login?ReturnUrl=%2F%3FGB%3DMjI2fC0x

【问题讨论】：
-
显示你的代码，你是如何渲染注销
ActionLink的？我很肯定你必须自己处理这个问题RedirecToAction或其他东西。 -
@Hashka 因为您在注销表单上执行
asp-route-GB="@Url.Action("Index", "Home", new { area = "" })"，但注销操作需要returnUrl。将其更新为类似于其他链接上的asp-route-returnUrl="@Model.ReturnUrl"。 -
你想要一个带returnurl的链接，所以你不需要使用asp-route-GB，它不会去HomeController/Index的链接。
-
@Pirate & Yiyi，完成。但是看看我的更新帖子......
