Blazor WebAssembly .NET Core 托管迁移到 .NET 8，无需 CascadingAuthenticationState 组件

Question

我有一些 .NET Core 托管的 Web 程序集项目，它在外部公司服务器上使用 OIDC 身份验证，配置为：

builder.Services.AddOidcAuthentication(opt =>
{
    opt.ProviderOptions.Authority = "https://xx.xx.pl/auth/realms/xx";
    opt.ProviderOptions.ClientId = "xxxx";
    opt.ProviderOptions.DefaultScopes.Add("email");
    opt.ProviderOptions.ResponseType = "code";
});

我想要这样的：

https://learn.microsoft.com/en-us/aspnet/core/migration/70-80?view=aspnetcore-8.0&tabs=visual-studio#update-a-blazor-web assembly-app

在 .NET 8 中，我不使用

CascadingAuthenticationState

组件，所以如果我添加：

builder.Services.AddCascadingAuthenticationState();

没有任何改变/重定向，因为它应该/没有任何中断。

但是当我删除

<CascadingAuthenticationState>

组件时，当我运行时，我看到未授权 - 好吧

按照应有的方式重定向到外部登录页面，我可以登录，然后返回“我的页面”

我看到“身份验证完成登录...”，但它没有重定向到上一页，而是失败并显示：

添加

builder.Services.AddOptions();
builder.Services.AddAuthorizationCore();

我做错了什么？
