如何在.Net Core 2.0的Razor页面中检查用户是否已通过身份验证 [英] How to check if user is authenticated in Razor pages of .Net Core 2.0

问题描述

我想检查用户是否在Razor页面的ASP.NET Core 2.0应用程序中登录.以下代码在.NET 4.6.1中有效:

I would like to check if a user is logged in in an ASP.NET Core 2.0 application in a Razor page. The following code worked in .NET 4.6.1:

@if (!Request.IsAuthenticated)
{
    <p><a href="@Url.Action("Login", "Account")" class="btn btn1-success btn-lg" role="button" area="">Sign In &raquo;</a></p>
}

如何在Core 2.0中做到这一点?

How can I do this in Core 2.0?

推荐答案

编辑:大卫当然是正确的.

Edit: David is right of course.

只需检查User或HttpContext.User.Identity.IsAuthenticated是否为true.

@if(!User.Identity.IsAuthenticated) 
{
    ...
}
