ASP.Net用户名电子邮件 [英] ASP.Net UserName to Email

问题描述

我对新的ASP.NET身份（RTM）工作，我不知道我将如何去有关更改注册，并从一个用户名电子邮件登录。

I am working with the new ASP.NET Identity (RTM) and I was wondering how would I go on about changing registering and login from being a UserName to an Email.

的想法是，我希望我的用户注册使用他们的电子邮件和密码（电子邮件也可以使用外部登录收购），他们建立在顶部的显示名/用户名。

The idea is that I want my users to sign up using their e-mail and a password (e-mail can also be acquired using external login) and they set-up a display name/username on top.

我看着IdentityUser，我可以看到该用户名是存在的，但是因为这是装在ASP.Net身份不能改变的。

I've looked at IdentityUser and I can see that UserName is there, however since that is packed in ASP.Net Identity that can not be changed.

我知道我可以使用用户名作为电子邮件，使用自定义的验证，然后有一个额外的属性，ApplicationUser称为显示名称但更是一个黑客不是一个解决方案。

I know I could use 'UserName' as a e-mail, with a custom validator and then have an extra attribute for ApplicationUser called DisplayName but that is more of a hack than a solution.

我希望我的问题是清楚的。提前致谢。

I hope my question is clear. Thanks in advance.

推荐答案

如果你真的想使用电子邮件地址登录，那么，恕我直言，有黑客你的建议是最好的办法。因为，如果你坚持正确地做你必须至少

If you really want to use e-mail address to log in, then, IMHO, the "hack" you suggested is the best approach. Because, if you insist on "doing it properly" you'll have to at least

• 修改数据库模式，显然


• 确保用户名的唯一性自己（你可以做一个数据库约束/索引你这样做，但你必须找到一个好办法来处理错误，并将其报告给用户）


• 找到一个很好的替代品只是在你写作User.Identity.UserNamecode


• 可能更加

在另一方面，如果你决定要黑客则需要用户名字段

On the other hand, if you decide to "hack" the UserName field you need to

• 修改RegisterViewModel验证（添加[EmailAddress的]将UserName属性），可能稍微定制[显示（名称= ...）]等。



• 使您的AccountController用于确保UserManager.UserValidator实例允许在电子邮件地址中使用特殊字符。要做到这一点，确保其非默认的构造函数如下：

• modify RegisterViewModel validation (add [EmailAddress] to the UserName property), probably slightly customize [Display(Name=...)] etc.

• make sure UserManager.UserValidator instance used in your AccountController allows special characters used in e-mail addresses. To do this, make sure its nondefault constructor looks like this:

public AccountController(UserManager<ApplicationUser> userManager)
{
    UserManager = userManager;
    var userValidator = UserManager.UserValidator as UserValidator<ApplicationUser>;
    userValidator.AllowOnlyAlphanumericUserNames = false;
}

我希望这能帮助你权衡这两种方法的利弊，并拿出最好的解决方案。祝你好运！

I hope this could help you weigh the pros and cons of both approaches and come up with the best solution. Good luck!
