服务器端Blazor（预览版6）-是否可以要求对特定页面进行身份验证？

Question

对于Blazor服务器托管页面-是否可以要求身份验证？基于以下文档：

https://docs.microsoft.com/en-au/aspnet/core/security/authorization/policies?view=aspnetcore-3.0

我已将以下内容添加到我的Startup.cs中：

public void ConfigureServices(IServiceCollection services)
{
  services.AddMvc().SetCompatibilityVersion( CompatibilityVersion.Version_2_2 );

  services.AddAuthorization(options =>
  {
      options.AddPolicy("Private", policy => policy.RequireAuthenticatedUser() );
  });
}

这是我放在fetchdata页面顶部的内容：

@page "/fetchdata"
@using HollyTest.Data
@inject WeatherForecastService ForecastService
@attribute [Authorize(Policy="Private")]

<h1>Weather forecast</h1>

<p>This component demonstrates fetching data from a service.</p>

有人可以告诉我我走的路是否正确吗？
