在Blazor中将Identity与AddDbContextFactory结合使用

public void ConfigureServices(IServiceCollection services)
{
    // 注册Identity服务
    services.AddIdentity<ApplicationUser, IdentityRole>()
        .AddEntityFrameworkStores<ApplicationDbContext>()
        .AddDefaultTokenProviders();

    // 注册数据库上下文工厂
    services.AddDbContextFactory<ApplicationDbContext>(options =>
        options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

    // 其他服务配置...
}

@inject SignInManager<ApplicationUser> SignInManager
@inject IDbContextFactory<ApplicationDbContext> DbContextFactory

@code {
    // 使用SignInManager进行身份验证
    private async Task Login()
    {
        var result = await SignInManager.PasswordSignInAsync(username, password, rememberMe, lockoutOnFailure);
        if (result.Succeeded)
        {
            // 登录成功
        }
        else
        {
            // 登录失败
        }
    }

    // 使用DbContextFactory获取数据库上下文实例
    private async Task GetData()
    {
        using var dbContext = DbContextFactory.CreateDbContext();
        var data = await dbContext.SomeTable.ToListAsync();
        // 处理数据
    }
}
