获取身份中的当前用户电子邮件 [英] get current user email in Identity

问题描述

我使用IIdentity界面获取当前的userid和username.

I use IIdentity interface For Getting current userid and username.

因此实现以下方法:

private static IIdentity GetIdentity()
{
    if (HttpContext.Current != null && HttpContext.Current.User != null)
    {
        return HttpContext.Current.User.Identity;
    }

    return ClaimsPrincipal.Current != null ? ClaimsPrincipal.Current.Identity : null;
}

然后在我的IoC容器[structuremap]中添加此代码:_.For<IIdentity>().Use(() => GetIdentity());.

And Add this code: _.For<IIdentity>().Use(() => GetIdentity()); in my IoC Container[structuremap].

用法

this._identity.GetUserId();
this._identity.GetUserName();
this._identity.IsAuthenticated

现在我要实现GetEmailAdress方法，该怎么做?

Now I Want to Implement GetEmailAdress Method, How To do this?

示例

this._identity.GetEmailAdress();

使用this._identity.GetUserName();时，请勿获取用户名数据库.

When use this._identity.GetUserName(); do not get username form database.

推荐答案

您可以在以下几行中做一些事情:

You could do something on these lines:

public static class IdentityExtensions
{
    public static string GetEmailAdress(this IIdentity identity)
    {
        var userId = identity.GetUserId();
        using (var context = new DbContext())
        {
            var user = context.Users.FirstOrDefault(u => u.Id == userId);
            return user.Email;
        }
    }        
}

然后您将可以像以下方式访问它:

and then you will be able to access it like:

this._identity.GetEmailAdress();
