如何在ASP.NET Core中获取当前用户

User.FindFirst(ClaimTypes.NameIdentifier).Value

编辑构造函数

下面的代码有效：

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

编辑RTM

您应该注册

IHttpContextAccessor

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