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

问题描述

我找到了这个链接:

如何获取当前登录的用户 ID ASP.NET Core

但答案都已经过时了！

这个 SO 帖子也不能成为解决方案，它只是一个样板解决方法:我应该如何从我的 MVC 6 视图中访问我的 ApplicationUser 属性?

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 操作中:base.User 不是 ApplicationUser 类型，base.User.Identity 也不是.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.

那么我如何在登录时访问我放在 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，需要依赖UserManager.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);
    }
 }

返回当前用户，并允许您访问他们的所有属性.

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

这是在一个动作里面:

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