首先是在 Microsoft Entra admin center 中配置你的应用程序角色

 然后分配用户到你创建的角色

1. 首先从下图找到你要配置的程序

2. 然后找到分配用户到角色的地方

选择用户

再选择角色

 这样就成功给用户分配了权限

接下来就可以在Blazor页面中读取了

@using Microsoft.AspNetCore.Components.Authorization
@inject AuthenticationStateProvider AuthenticationStateProvider@code {private ClaimsPrincipal user;protected override async Task OnInitializedAsync(){LoadFromName();NavigationManager.LocationChanged += OnLocationChanged;var authState = await AuthenticationStateProvider.GetAuthenticationStateAsync();user = authState.User;var claims = user.Claims.Where(c => c.Type == "http://schemas.microsoft.com/ws/2008/06/identity/claims/role").ToList();var IsUser = claims.Any(claim => claim.Value.ToLower() == "user");var IsSuperUser = claims.Any(claim => claim.Value.ToLower() == "superuser");}}
