網絡核心：“ HttpContext”不包含“當前”的定義

Question

我正在將一個項目從.Net 4.6.2遷移到.Net Core 2.0。 我在下面收到錯誤消息。 'HttpContext' does not contain a definition for 'Current'

我該如何解決？

原始代碼：

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 &&

錯誤代碼：

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

嘗試輸入的代碼：

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

錯誤：

非靜態字段，方法或屬性'HttpContext.Session'需要對象引用

也許您可以使用HttpContext.User.Identity.IsAuthenticated
