使用相同的用户名和电子邮件创建用户始终返回无效的用户名错误

Question

尝试使用 .net core 在标识表中创建用户。但它总是返回错误无效的用户名。

        var user = new ApplicationUser();
        user.UserName = "[e-mail]";
        user.Email = "[e-mail]";
        string userPWD = "Admin@123";
        var chkUser = await UserManager.CreateAsync(user, userPWD);

配置服务如下。

 public void ConfigureServices(IServiceCollection services)
    {
        services.Configure<CookiePolicyOptions>(options =>
        {
            options.CheckConsentNeeded = context => true;
            options.MinimumSameSitePolicy = SameSiteMode.None;
        });
        services.AddDbContext<ApplicationDbContext>(options =>
                                                                   options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
        services.AddIdentity<ApplicationUser, IdentityRole>(options =>
        {
            options.User.AllowedUserNameCharacters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-._@/";
        })
         .AddEntityFrameworkStores<ApplicationDbContext>().AddDefaultTokenProviders();
        services.Configure<IdentityOptions>(options =>
        {
            // Default Password settings.
            options.Password.RequireDigit = true;
            options.Password.RequireLowercase = true;
            options.Password.RequireNonAlphanumeric = true;
            options.Password.RequireUppercase = true;
            options.Password.RequiredLength = 6;
            options.Password.RequiredUniqueChars = 1;
        });
        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
    }

已将 AllowedUserNameCharacters 添加为 "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-._@/">

但仍然返回错误 用户名"无效，只能包含字母或数字。

您可以在用户验证器上关闭此限制：

UserManager.UserValidator = new UserValidator<TUser>(UserManager) { AllowOnlyAlphanumericUserNames = false }
