Asp.Net标识中带破折号的标识电子邮件

Question

我正在使用ASP.NET MVC标识，并且当我添加表单的电子邮件时[e-mail]我收到验证错误消息

用户名[e-mail]无效，只能包含字母或数字。

如何更改验证以允许接受电子邮件？

我的cshtml是：

@using (Html.BeginForm("Login", "Account", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { role = "form" }))
        {
            @Html.AntiForgeryToken()
            <div class="reg-header">
                <h2>Register</h2>
            </div>
            <fieldset>
                @if (ViewBag.IsRegister)
                {
                    @Html.ValidationSummary(true, "", new { @class = "text-danger" })
                }
                <div class="margin-bottom-20">
                    @Html.LabelFor(m => m.RegisterViewModel.FirstName)<br />
                    <div class="input-group">
                        <span class="input-group-addon"><i class="fa fa-user"></i></span>
                        @Html.TextBoxFor(m => m.RegisterViewModel.FirstName, new { @class = "form-control" })
                    </div>
                    @Html.ValidationMessageFor(m => m.RegisterViewModel.FirstName, "", new { @class = "text-danger" })
                </div>
                <div class="margin-bottom-20">
                    @Html.LabelFor(m => m.RegisterViewModel.LastName)<br />
                    <div class="input-group">
                        <span class="input-group-addon"><i class="fa fa-user"></i></span>
                        @Html.TextBoxFor(m => m.RegisterViewModel.LastName, new { @class = "form-control" })
                    </div>
                    @Html.ValidationMessageFor(m => m.RegisterViewModel.LastName, "", new { @class = "text-danger" })
                </div>
                <div class="margin-bottom-20">
                    @Html.LabelFor(m => m.RegisterViewModel.Email)<br />
                    <div class="input-group">
                        <span class="input-group-addon"><i class="fa fa-user"></i></span>
                        @Html.TextBoxFor(m => m.RegisterViewModel.Email, new { @class = "form-control" })
                    </div>
                    @Html.ValidationMessageFor(m => m.RegisterViewModel.Email, "", new { @class = "text-danger" })
                </div>
                <div class="margin-bottom-20">
                    @Html.LabelFor(m => m.RegisterViewModel.Password)<br />
                    <div class="input-group ">
                        <span class="input-group-addon"><i class="fa fa-lock"></i></span>
                        @Html.PasswordFor(m => m.RegisterViewModel.Password, new { @class = "form-control" })
                    </div>
                    @Html.ValidationMessageFor(m => m.RegisterViewModel.Password, "", new { @class = "text-danger" })
                </div>
                <div class="margin-bottom-20">
                    @Html.LabelFor(m => m.RegisterViewModel.ConfirmPassword)<br />
                    <div class="input-group">
                        <span class="input-group-addon"><i class="fa fa-lock"></i></span>
                        @Html.PasswordFor(m => m.RegisterViewModel.ConfirmPassword, new { @class = "form-control" })
                        <div class="clear"></div>
                    </div>
                    @Html.ValidationMessageFor(m => m.RegisterViewModel.ConfirmPassword, "", new { @class = "text-danger" })
                </div>
                <div class="row">
                    <div class="col-md-12">
                        <button class="btn-u" type="submit" name="command" value="Register">Register</button>
                    </div>
                </div>
            </fieldset>
        }

这是我的控制器：

                RegisterViewModel model = login.RegisterViewModel;
                var user = new ApplicationUser() { UserName = model.Email, FirstName = model.FirstName, LastName = model.LastName, UserRole = UserRole.Rider };
                IdentityResult result = await UserManager.CreateAsync(user, model.Password);
                if (result.Succeeded)
                {
                    await SignInAsync(user, isPersistent: false);
                    // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
                    // Send an email with this link
                    // string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
                    // var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
                    // await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking <a href="" + callbackUrl + "">here</a>");
                    return RedirectToLocal(returnUrl);
                    //return RedirectToAction("Index", "Home");
                }
                else
                {
                    ViewBag.ReturnUrl = returnUrl;
                    AddErrors(result);
                }

Answer 1

UserManager中使用的默认UserValidator具有设置为true的属性AllowOnlyAlphanumericUserNames。。您需要覆盖此项以允许使用特殊字符。一个可能的解决方案是用自己的实现覆盖UserManager

public class ApplicationUserManager : UserManager<ApplicationUser>
{
    public ApplicationUserManager(IUserStore<ApplicationUser> store) : base(store)
    {
        this.UserValidator = new UserValidator<ApplicationUser>(this) { AllowOnlyAlphanumericUserNames = false };
    }
}
public class ApplicationUser : IdentityUser
{
    //Custom Properties etc.
}

感谢您在这方面的帮助。

事实上，我通过在账户控制器中放入以下内容来解决这个问题

    public AccountController(UserManager<ApplicationUser> userManager)
    {
        var provider = new Microsoft.Owin.Security.DataProtection.DpapiDataProtectionProvider("One");
        userManager.UserTokenProvider = new Microsoft.AspNet.Identity.Owin.DataProtectorTokenProvider<ApplicationUser>(provider.Create("EmailConfirmation"));
        UserManager = userManager;
        UserManager.UserValidator = new UserValidator<ApplicationUser>(UserManager)
        {
            AllowOnlyAlphanumericUserNames = false
        };
    }
