Hir*_*ndo 2 c# asp.net-identity asp.net-core blazor blazor-server-side
我有一个 .net cor 3.1 Blazor 服务器项目。我在这个项目中使用默认的身份系统。我想在不登录的情况下访问特定的剃须刀页面。我怎么做？任何想法？
我尝试添加@attribute [AllowAnonymous]到剃刀页面。但这对我不起作用
_Host.cshtml
page "/"
@using Microsoft.AspNetCore.Authorization
@namespace has.Pages
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
@attribute [Authorize]
@{
Layout = null;
}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />

应用剃刀
<CascadingAuthenticationState>
<Router AppAssembly="@typeof(Program).Assembly">
<Found Context="routeData">
<RouteView RouteData="@routeData" DefaultLayout="@typeof(MainLayout)" />
</Found>
<NotFound>
<LayoutView Layout="@typeof(MainLayout)">
<Error404 />
</LayoutView>
</NotFound>
</Router>
<AntContainer />
</CascadingAuthenticationState>
我找到了答案。@attribute [AllowAnonymous]我在该文件夹内的单独文件夹中创建了另一个 _Host.cshtml Pages，并将我的剃刀页面放入该文件夹中。
添加@layout PublicLayout到您的匿名访问组件。就我而言，是 MyAnonymousComponent.razor。PublicLayout是PublicSection/PublicLayout.razor
我的项目结构是这样的
MyProject
-Pages
-Section1
-Section2
-Shared
_Layout.cshtml
-PublicSection // This folder has anonymous access components
_Host.cshtml
_Layout.cshtml
MyAnonymousComponent.razor
PublicApp.razor
PublicLayout.razor
_Host.cshtml
-Shared
MainLayout.razor
App.razor
_Imports.razor
Program.cs
Startup.cs
MyProject
-Pages
-Section1
-Section2
-Shared
_Layout.cshtml
-PublicSection // This folder has anonymous access components
_Host.cshtml
_Layout.cshtml
MyAnonymousComponent.razor
PublicApp.razor
PublicLayout.razor
_Host.cshtml

@page "/publicsection"
@using has.Pages.PublicRazor
@using Microsoft.AspNetCore.Authorization
@namespace has.Pages
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
@attribute [AllowAnonymous]
@{

}
