更改 ASP.NET Core 服务 DefaultIdentity 不会更改密码选项

Question

在脚手架身份验证之后，我很难更改身份选项。

我使用了这个命令：

dotnet new webapp --auth Individual -o mywebapp

然后，我更改了 Startup.cs 文件，更改了身份选项：

 public void ConfigureServices(IServiceCollection services)
    {
        services.Configure<CookiePolicyOptions>(options =>
        {
            // This lambda determines whether user consent for non-essential cookies is needed for a given request.
            options.CheckConsentNeeded = context => true;
            options.MinimumSameSitePolicy = SameSiteMode.None;
        });

        services.AddDbContext<ApplicationDbContext>(options =>
            options.UseSqlite(
                Configuration.GetConnectionString("DefaultConnection")));

        services.AddDefaultIdentity<IdentityUser>(config =>
        {
            // TODO
            //config.SignIn.RequireConfirmedEmail = true;
        })
            .AddDefaultUI(UIFramework.Bootstrap4)
            .AddEntityFrameworkStores<ApplicationDbContext>();


        services.Configure<IdentityOptions>(options =>
        {
            // Password settings
            options.Password.RequireDigit = true;
            options.Password.RequireNonAlphanumeric = false;
            options.Password.RequireUppercase = false;
            options.Password.RequireLowercase = false;
            options.Password.RequiredLength = 3;
            options.Password.RequiredUniqueChars = 1;

            // Lockout settings
            options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(5);
            options.Lockout.MaxFailedAccessAttempts = 5;
            options.Lockout.AllowedForNewUsers = true;

            // User settings
            options.User.RequireUniqueEmail = true;
        });

设置options.Password.RequiredLength 无效。

当我运行应用程序时，浏览器显示错误消息：

The Password must be at least 6 and at max 100 characters long.

我没有预料到错误“至少 6”；从我读到的应该是“3”。 我该如何解决这个问题？

这么多的黑魔法正在发生，搜索“至少”的框架什么也没有发现。

编辑---> 添加搭建好的 ViewModel 代码：

namespace netplus.Models.Account
{
   public class RegisterViewModel
   {
      [Required, MaxLength(256)]
      public string Username { get; set; }

      [Required, DataType(DataType.Password)]
      public string Password { get; set; }

      [DataType(DataType.Password), Compare(nameof(Password))]
      public string ConfirmPassword { get; set; }
   }
}

Answer 1

对于IdentityOptions，配置为_userManager.CreateAsync(user, Input.Password)验证密码。

对于The Password must be at least 6 and at max 100 characters long，这由RegisterModel 中的ViewModel 控制。

您无法使用IdentityOptions 来控制此客户端验证。

按照以下步骤控制它：

1. 右键项目->Add New Scaffold Item->Identity->Check Account\Register->右击Data context class

2. 打开RegisterModel并修改InputModel进行客户端验证

   public class InputModel
   {
       [Required]
       [EmailAddress]
       [Display(Name = "Email")]
       public string Email { get; set; }
   
       [Required]
       [StringLength(100, ErrorMessage = "The {0} must be at least {2} and at max {1} characters long.", MinimumLength = 6)]
       [DataType(DataType.Password)]
       [Display(Name = "Password")]
       public string Password { get; set; }
   
       [DataType(DataType.Password)]
       [Display(Name = "Confirm password")]
       [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
       public string ConfirmPassword { get; set; }
   }
