如何在ASP.NET Core中获得当前用户 [英] How to get current user in asp.net core

问题描述

我想找一个当前用户来获取诸如电子邮件之类的用户信息. 但是我不能在asp.net核心中做到这一点.我很混乱 这是我的代码.

I want to get a current user for getting information of a user such as an email. But I can't do that in asp.net core. I'm so confused This is my code.

HttpContext在控制器的构造函数中几乎为空. 在每个动作中都吸引用户是不好的.我想一次获取用户信息并将其设置为ViewData;

HttpContext almost is null in constructor of controller. It's not good to get a user in each action. I Wanna get information of user once and set them into ViewData;

public DashboardController()
{
    var user = HttpContext.User.GetUserId();
}

推荐答案

User.FindFirst(ClaimTypes.NameIdentifier).Value

编辑构造函数

以下代码有效:

public Controller(IHttpContextAccessor httpContextAccessor)
{
    var userId = httpContextAccessor.HttpContext.User.FindFirst(ClaimTypes.NameIdentifier).Value 
}

为RTM编辑

您应该注册IHttpContextAccessor:

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddHttpContextAccessor();
    }
