从asp.net核心标识获取applicationuser的属性 [英] Get property of applicationuser from the asp.net core identity

问题描述

我找到了此链接:

如何获取当前登录的用户ID ASP.NET Core

但是答案都过时了！

这个SO帖子既不能作为解决方案，也可以作为解决方法:

And this SO post can not neither be a solution, its just a boilerplate workaround: How should I access my ApplicationUser properties from within my MVC 6 Views?

在mvc动作中:base.User不是ApplicationUser类型，也不是base.User.Identity.两者都不能转换为ApplicationUser.

In the mvc action: base.User is not of type ApplicationUser neither is base.User.Identity. Both can not be casted into ApplicationUser.

那么登录后如何访问放置在applicationuser对象中的自定义属性?

So how can I access my custom properties put inside the applicationuser object when logged in?

推荐答案

对于控制器，请依赖UserManager<ApplicationUser>.然后，您可以通过请求的HttpContext访问ApplicationUser.我为我的项目写了一个扩展方法:

For the controller, have a dependency on UserManager<ApplicationUser>. Then, you can access the ApplicationUser through the HttpContext of the request. I wrote an extension method for my project:

 public static class IdentityExt
 {
    public static Task<T> GetCurrentUser<T>(this UserManager<T> manager, HttpContext httpContext) where T: class{
        return manager.GetUserAsync(httpContext.User);
    }
 }

这将返回当前用户，并允许您访问其所有属性.

That returns the current user, and will allow you to access all of their properties.

这里是动作内:

public Task<IActionResult> Index(){
     var user = await _userManager.GetCurrentUser(HttpContext);
}
