网络核心：“ HttpContext”不包含“当前”的定义

Question

I am migrating a project from .Net 4.6.2 into .Net Core 2.0. I am receiving error below. 'HttpContext' does not contain a definition for 'Current'

How would I resolve this?

Original Code:

public class CustomerAuthorize : AuthorizeAttribute
{
    /// Gets or sets a session variable indicates that the logged in user has been already authorized to login to the system. 
    private bool IsAuthorized
    {
        get
        {
            if (HttpContext.Current.Session["IsAuthorized"] != null &&

Error Code:

'HttpContext' does not contain a definition for 'Current'

Attempted Code:

public class CustomerAuthorize : AuthorizeAttribute
{
    // Gets or sets a session variable indicates that the logged in user has been already authorized to login to the system. 

    const string IsAuthorized2 = "IsAuthorized";
    private bool IsAuthorized
    {
        get
        {
            if (HttpContext.Session.GetString(IsAuthorized2) != null

Error:

An object reference is required for the non-static field, method, or property 'HttpContext.Session'

Answer 1

也许您可以使用HttpContext.User.Identity.IsAuthenticated
