blazor 项目中的自定义身份验证状态提供程序在服务器端不起作用

Question

大家好!我想让我的自定义身份验证模式Blazor WebAssembly应用程序(这是工作室创建3项目——客户端,服务器,共享)。我的想法是避免IS4的权威，让我自己的"内部"。用户的测试目的和了解auth机械的工作以及。我通过创建我的自定义AuthenticationStateProvider?就像官方文件中显示的那样。这是我的AuthenticationStateProvider类:

public class CustomAuthStateProvider : AuthenticationStateProvider
{
private bool _isLoggedIn = true;
//this is a parameter defininng whether user logged in or not
//changed by reflection
public bool IsLoggedIn
{
get
{
return _isLoggedIn;
}
set
{
_isLoggedIn = value;
NotifyAuthenticationStateChanged(GetAuthenticationStateAsync());
}
}
private static CustomAuthStateProvider _myInstance = null;

public Serilog.ILogger _logger { get; set; }
public override Task<AuthenticationState> GetAuthenticationStateAsync()
{
ClaimsIdentity identity;
Task<AuthenticationState> rez;
if (IsLoggedIn)
{
identity = new ClaimsIdentity(new[]
{
new Claim(ClaimTypes.Name, "User01"),
}, "Fake authentication type");
}
else
{
identity = new ClaimsIdentity();
}
var user = new ClaimsPrincipal(identity);
rez = Task.FromResult(new AuthenticationState(user));
return rez;
}
public static CustomAuthStateProvider GetMyInstance(Serilog.ILogger logger = null, string mySide = "")
{
//implementing singleton
if (_myInstance == null)
{
_myInstance = new CustomAuthStateProvider();
_myInstance._logger = logger;
}
return _myInstance;
}
}

这是我如何插入客户端(program.cs)

builder.Services.AddSingleton<AuthenticationStateProvider>(x => CustomAuthStateProvider.GetMyInstance(Log.Logger, "Client"));

这是我如何插入服务器端(startup.cs)

services.AddSingleton<AuthenticationStateProvider, CustomAuthStateProvider>();

问题:它在客户端工作得很好，这意味着我可以登录，注销和使用AutorizeView和类似的标签。但它不能在服务器端工作，这意味着HttpContext。用户看不到任何经过认证的用户，不能使用[authorization]和类似的属性。我做错了什么?HttpContext。用户是否连接到asp.net核心项目中的AuthenticationStateProvider ?谢谢,-)

这是我最近为一个服务器端项目整理的一个非常简单的Test AuthenticationStateProvider。

using Microsoft.AspNetCore.Components.Authorization;
using System.Security.Claims;
using System.Threading.Tasks;
namespace Blazor.Auth.Test
{
public class TestAuthenticationStateProvider : AuthenticationStateProvider
{
public TestUserType UserType { get; private set; } = TestUserType.None;
private ClaimsPrincipal Admin
{
get
{
var identity = new ClaimsIdentity(new[]
{
new Claim(ClaimTypes.Sid, "985fdabb-5e4e-4637-b53a-d331a3158680"),
new Claim(ClaimTypes.Name, "Administrator"),
new Claim(ClaimTypes.Role, "Admin")
}, "Test authentication type");
return new ClaimsPrincipal(identity);
}
}
private ClaimsPrincipal User
{
get
{
var identity = new ClaimsIdentity(new[]
{
new Claim(ClaimTypes.Sid, "024672e0-250a-46fc-bd35-1902974cf9e1"),
new Claim(ClaimTypes.Name, "Normal User"),
new Claim(ClaimTypes.Role, "User")
}, "Test authentication type");
return new ClaimsPrincipal(identity);
}
}
private ClaimsPrincipal Visitor
{
get
{
var identity = new ClaimsIdentity(new[]
{
new Claim(ClaimTypes.Sid, "3ef75379-69d6-4f8b-ab5f-857c32775571"),
new Claim(ClaimTypes.Name, "Visitor"),
new Claim(ClaimTypes.Role, "Visitor")
}, "Test authentication type");
return new ClaimsPrincipal(identity);
}
}
private ClaimsPrincipal Anonymous
{
get
{
var identity = new ClaimsIdentity(new[]
{
new Claim(ClaimTypes.Sid, "0ade1e94-b50e-46cc-b5f1-319a96a6d92f"),
new Claim(ClaimTypes.Name, "Anonymous"),
new Claim(ClaimTypes.Role, "Anonymous")
}, null);
return new ClaimsPrincipal(identity);
}
}
public override Task<AuthenticationState> GetAuthenticationStateAsync()
{
var task = this.UserType switch
{
TestUserType.Admin => Task.FromResult(new AuthenticationState(this.Admin)),
TestUserType.User => Task.FromResult(new AuthenticationState(this.User)),
TestUserType.None => Task.FromResult(new AuthenticationState(this.Anonymous)),
_ => Task.FromResult(new AuthenticationState(this.Visitor))
};
return task;
}
public Task<AuthenticationState> ChangeUser(TestUserType userType)
{
this.UserType = userType;
var task = this.GetAuthenticationStateAsync();
this.NotifyAuthenticationStateChanged(task);
return task;
}
}
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
namespace Blazor.Auth.Test
{
public enum TestUserType
{
None,
Visitor,
User,
Admin
}
}

启动regstration:

services.AddScoped<AuthenticationStateProvider, TestAuthenticationStateProvider>();

添加到NavMenu中的简单组件，用于切换用户。

<AuthorizeView>
<Authorized>
<div class="m-1 p-1 text-white">
@user.Identity.Name
</div>
</Authorized>
<NotAuthorized>
<div class="m-1 p-1 text-white">
Not Logged In
</div>
</NotAuthorized>
</AuthorizeView>
<div class="m-1 p-3">
<select class="form-control" @onchange="ChangeUser">
@foreach (var value in Enum.GetNames(typeof(TestUserType)))
{
<option value="@value">@value</option>
}
</select>
</div>
@code {
[CascadingParameter] public Task<AuthenticationState> AuthTask { get; set; }
[Inject] private AuthenticationStateProvider AuthState { get; set; }
private System.Security.Claims.ClaimsPrincipal user;
protected async override Task OnInitializedAsync()
{
var authState = await AuthTask;
this.user = authState.User;
}
private async Task ChangeUser(ChangeEventArgs e)
{
var en = Enum.Parse<TestUserType>(e.Value.ToString());
var authState = await ((TestAuthenticationStateProvider)AuthState).ChangeUser(en);
this.user = authState.User;
}
}
