在身份中获取当前用户的电子邮件

get current user email in Identity

我使用 IIdentity 界面获取当前 useridusername

所以实现以下方法:

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;
}

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

用法

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

现在我想实现GetEmailAdress方法,如何实现?

示例

this._identity.GetEmailAdress();

当使用 this._identity.GetUserName(); 时,不要从 数据库.

中获取用户名

你可以在这些行上做一些事情:

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;
        }
    }        
}

然后您将能够像这样访问它:

this._identity.GetEmailAdress();

可以在ASP.NET Identity获取当前用户如下图:

ApplicationUser user = System.Web.HttpContext.Current.GetOwinContext()
    .GetUserManager<ApplicationUserManager>()
    .FindById(System.Web.HttpContext.Current.User.Identity.GetUserId());

//If you use int instead of string for primary key, use this:
ApplicationUser user = System.Web.HttpContext.Current.GetOwinContext()
    .GetUserManager<ApplicationUserManager>()
    .FindById(Convert.ToInt32(System.Web.HttpContext.Current.User.Identity.GetUserId()));


AspNetUsers table:

获取自定义属性
ApplicationUser user = UserManager.FindByName(userName);
string mail= user.Email;

希望这对您有所帮助...

家庭控制器

 [AllowAnonymous]
        public ActionResult GetUserEmail()
        {
            try
            {
                var userID = User.Identity.GetUserId();
                ViewBag.EmailData = db.AspNetUsers.Where(s => s.Id == userID).Select(x => x.Email).FirstOrDefault().ToString();
                return Content(ViewBag.EmailData);
            }
            catch
            {
                return null;
            }
        }

并在视图中

@{
string USREmail = Html.Action("GetUserEmail", "Home").ToString();
}

您可以显示电子邮件

@USREmail
