如何从识别身份验证中排除剃刀页面和控制器？



我创建了一个具有标识(个人帐户)的blazor web组装项目，并且我通过复制fetchData创建了剃刀。剃刀到一个fetchPeople。Razor，我想允许匿名访问这个页面，这是我的源代码

@page "/fetchpeople"
@using Booking.Shared
@using Microsoft.AspNetCore.Authorization
@using Microsoft.AspNetCore.Components.WebAssembly.Authentication
@inject HttpClient Http
@attribute [AllowAnonymous]
<PageTitle>People</PageTitle>
<h1>People</h1>
<p>This component demonstrates fetching data from the server.</p>
@if (forecasts == null)
{
<p><em>Loading...</em></p>
}
else
{
<table class="table">
<thead>
<tr>
<th>Date</th>
<th>Temp. (C)</th>
<th>Temp. (F)</th>
<th>Summary</th>
</tr>
</thead>
<tbody>
@foreach (var forecast in forecasts)
{
<tr>
<td>@forecast.Id</td>
<td>@forecast.FirstName</td>
<td>@forecast.LastName</td>
<td>@forecast.LastName</td>
</tr>
}
</tbody>
</table>
}
@code {
private PersonModel[]? forecasts;
protected override async Task OnInitializedAsync()
{
forecasts = await Http.GetFromJsonAsync<PersonModel[]>("People");
}
}

控制器:

using Booking.Shared;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using System.Xml.Linq;
using System.Collections.Generic;
using Booking.Server.Data;
using Microsoft.AspNetCore.Authorization;
namespace a1.Server.Controllers
{
[AllowAnonymous]
[ApiController]
[Route("[controller]")]
public class PeopleController : ControllerBase
{

private readonly ILogger<PeopleController> _logger;
private readonly IDataAccess data;

public PeopleController(ILogger<PeopleController> logger, IDataAccess data)
{
_logger = logger;
this.data = data;
}
[HttpGet]
public IEnumerable<PersonModel> Get()
{
return data.testSql().Result.ToArray();
}
}
}

访问页面时，控制台

出现错误

有人知道怎么修理它吗?

我已经在program.cs中添加了这些行

builder.Services.AddHttpClient("Booking.ServerAPI.Anonymous", client =>
{
client.BaseAddress = new Uri(builder.HostEnvironment.BaseAddress);
});

fetchPeople.razor

@page "/fetchpeople"
@using Booking.Shared
@inject IHttpClientFactory _factory
@inject HttpClient Http
<PageTitle>People</PageTitle>
<h1>People</h1>
<p>This component demonstrates fetching data from the server.</p>
@if (forecasts == null)
{
<p><em>Loading...</em></p>
}
else
{
<table class="table">
<thead>
<tr>
<th>Date</th>
<th>Temp. (C)</th>
<th>Temp. (F)</th>
<th>Summary</th>
</tr>
</thead>
<tbody>
@foreach (var forecast in forecasts)
{
<tr>
<td>@forecast.Id</td>
<td>@forecast.FirstName</td>
<td>@forecast.LastName</td>
<td>@forecast.LastName</td>
</tr>
}
</tbody>
</table>
}
@code {
private PersonModel[]? forecasts;
protected override async Task OnInitializedAsync()
{
var httpClient = _factory.CreateClient("Booking.ServerAPI.Anonymous");
forecasts = await httpClient.GetFromJsonAsync<PersonModel[]>("People");
}
}
