防止身份警报被触发

Question

我正在做一个项目，我决定将电子邮件实现为用户名并完全删除默认的 MVC 用户名字段。我已经设置了这样的身份注册：

型号：

[Required]
    [EmailAddress]
    [Display(Name = "Email")]
    public string Email { get; set; }

    [Required]
    [StringLength(100, ErrorMessage = "The {0} must be at least {2} 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; }

控制器设置：

if (ModelState.IsValid)
        {
            var user = new ApplicationUser { UserName = model.Email, Email = model.Email };
            var result = await UserManager.CreateAsync(user, model.Password);
            if (result.Succeeded)
            { ...

但是，由于此更改，每当我遇到用户输入已存在的电子邮件的情况时，身份就会触发用户名和电子邮件已经存在。

如何防止在这种情况下触发 "Name is already taken" 警报？我试图从 "new ApplicationUser" 调用中删除用户名参数，但随后它向我发出警告，提示它也不能为 null。谢谢！

这一行 AddErrors(result); 导致了问题。您可以更改方法以忽略以 "Name"

开头的错误

private void AddErrors(IdentityResult result, string[] ignoreStartWith)
{
     foreach (var error in result.Errors)
     {
          if (!ignoreStartWith.Any(s => error.StartsWith(s)))
          {
                ModelState.AddModelError("", error);
          }
     }
}

并像

一样使用它

AddErrors(result, ignoreStartWith:new[] { "Name" });
