blazor 方案已存在：addidentities

Question

正如您在屏幕截图中看到的，我只有一处添加身份。我制作了一个自定义用户管理器并注册了它。

我不知道如何获得任何其他可能的重复项，它说它已经添加了

在此输入图片描述

using Microsoft.AspNetCore.Components.Authorization;
using Microsoft.AspNetCore.Identity;
using Microsoft.EntityFrameworkCore;
using Swamp.Components;
using Swamp.Components.Account;
using Swamp.Data;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents();

builder.Services.AddCascadingAuthenticationState();
builder.Services.AddScoped<IdentityUserAccessor>();
builder.Services.AddScoped<IdentityRedirectManager>();
builder.Services.AddScoped<AuthenticationStateProvider, IdentityRevalidatingAuthenticationStateProvider>();
var connectionString = builder.Configuration.GetConnectionString("DefaultConnection") ?? throw new InvalidOperationException("Connection string 'DefaultConnection' not found.");

builder.Services.AddDbContextFactory<ApplicationDbContext>(options =>
    options.UseSqlServer(connectionString));

builder.Services.AddQuickGridEntityFrameworkAdapter(); ;

builder.Services.AddAuthentication(options =>
    {
        options.DefaultScheme = IdentityConstants.ApplicationScheme;
        options.DefaultSignInScheme = IdentityConstants.ExternalScheme;
    })
    .AddIdentityCookies();

builder.Services.AddDbContext<ApplicationDbContext>(options =>
    options.UseSqlServer(connectionString));

builder.Services.AddQuickGridEntityFrameworkAdapter();
builder.Services.AddDatabaseDeveloperPageExceptionFilter();

builder.Services.AddIdentity<ApplicationUser, IdentityRole>()
    .AddUserManager<UserManagerExtension>()
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddSignInManager()
    .AddDefaultTokenProviders();
builder.Services.AddServerSideBlazor().AddCircuitOptions(x => x.DetailedErrors = true);

builder.Services.AddSingleton<IEmailSender<ApplicationUser>, IdentityNoOpEmailSender>();
var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseMigrationsEndPoint();
}
else
{
    app.UseExceptionHandler("/Error", createScopeForErrors: true);
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
    app.UseMigrationsEndPoint();
}

app.UseHttpsRedirection();

app.UseStaticFiles();
app.UseAntiforgery();


app.MapRazorComponents<App>()
    .AddInteractiveServerRenderMode();

// Add additional endpoints required by the Identity /Account Razor components.
app.MapAdditionalIdentityEndpoints();

app.Run();

我搜索了任何其他具有 Services.AddIdentities 的地方，但没有出现任何结果

当使用

AddIdentity

时，这将隐式添加一个方案名称为“Identity.Application”的cookie。

但是你使用另一个

.AddIdentityCookies();

，它基本上是相同的方案名称cookie。这是没有必要的。
