在布拉佐爾中：我正在創(chuàng)建一個自定義 AuthenticationStateProvider 類，以便我可以使用托管在 mssql 上的自定義用戶數(shù)據(jù)庫。我的自定義類是：public class ServerAuthenticationStateProvider : AuthenticationStateProvider{    string UserId;    string Password;    public void LoadUser(string _UserId, string _Password)    {        UserId = _UserId;        Password = _Password;    }    public override async Task<AuthenticationState> GetAuthenticationStateAsync()    {        var securityService = new SharedServiceLogic.Security();        var userService = new UserService();        var validPassword = await securityService.ValidatePassword(UserId, Password);        var authenticated = validPassword == true ? true : false;        var identity = authenticated            ? new ClaimsIdentity(await userService.GetClaims(UserId), "AuthCheck")            : new ClaimsIdentity();        var result = new AuthenticationState(new ClaimsPrincipal(identity));        return result;    }}然后我在 Startup.cs 中注冊它： public void ConfigureServices(IServiceCollection services) {        services.AddRazorPages();        services.AddServerSideBlazor();        services.AddSingleton<UserService>();        services.AddAuthorizationCore();        services.AddScoped<AuthenticationStateProvider, ServerAuthenticationStateProvider>(); }我的 App.razor 是：<CascadingAuthenticationState>    <Router AppAssembly="typeof(Startup).Assembly">        <NotFoundContent>            <p>Sorry, there's nothing at this address.</p>        </NotFoundContent>    </Router></CascadingAuthenticationState>現(xiàn)在我想使用 Index.razor 中的服務(wù)：@page "/"@using BadgerWatchWeb.Services@inject AuthenticationStateProvider AuthenticationStateProvider<h1>Sup</h1>由于錯誤，我無法運行此代碼。錯誤說AuthenticationStateProvider does not contain a definition of LoadUser。我認(rèn)為該服務(wù)將能夠使用 ServerAuthenticationStateProvider 中的類。難道不是這樣嗎？
