1.创建一个包含用户登录信息的用户表格。例如：

CREATE TABLE [dbo].[Users]( [Id] [int] IDENTITY(1,1) NOT NULL, [Username] nvarchar NOT NULL, [Password] nvarchar NOT NULL, [Role] [int] NOT NULL, CONSTRAINT [PK_Users] PRIMARY KEY CLUSTERED ([Id] ASC) )

2.在Blazor应用程序中使用ASP.NET Core Identity进行身份验证。

3.在客户端项目中添加以下包：

Microsoft.AspNetCore.Components.WebAssembly.Authentication

4.在程序启动的时候，将appsettings.json文件中的用户登录信息加载到内存中。例如：

builder.Services.AddHttpClient("ServerAPI", client => client.BaseAddress = new Uri(builder.HostEnvironment.BaseAddress)) .AddHttpMessageHandler(sp => { var handler = sp.GetService() .ConfigureHandler( authorizedUrls: new[] { "https://localhost:5001" }, scopes: new[] { "ServerAPI" }); return handler; });

builder.Services.AddSingleton( new HttpClient( new HttpClientHandler { ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAnyServerCertificateValidator }) { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });

// Load user login information from appsettings.json. var userSection = Configuration.GetSection("User"); if (userSection.Exists()) { var users = userSection.Get>(); if (users != null) { foreach (var user in users) { builder.Services.AddSingleton(user); } } }

5.在Blazor的页面中使用AuthenticationStateProvider获取用户的身份信息。例如：

@using Microsoft.AspNetCore.Components.WebAssembly.Authentication @using Microsoft.AspNetCore.Components.Authorization @inject AuthenticationStateProvider AuthenticationStateProvider

@code { private bool isAuthenticated; private string username; private string password;

protected override async Task OnInitializedAsync()
{
    var authState = await AuthenticationStateProvider.GetAuthenticationStateAsync();
    isAuthenticated
