tokenClient.RequestAuthorizationCodeTokenAsync正在清除HttpContext，可以防止这种情况发生吗?

问题描述

我有以下代码:

using IdentityModel.Client;
using Microsoft.AspNet.Identity;

var tokenClient = new HttpClient();

var testUserName = System.Web.HttpContext.Current.User.Identity.GetUserName(); // This returns a value
var tokenResult = await tokenClient.RequestAuthorizationCodeTokenAsync(
                    new AuthorizationCodeTokenRequest
                    {
                        Address = address,
                        Code = authorizationCode,
                        ClientId = clientId,
                        ClientSecret = clientSecret,
                        GrantType = "authorization_code",
                        RedirectUri = redirectUri
                    });
current = System.Web.HttpContext.Current; // This fails, Current is null
testUserName = System.Web.HttpContext.Current.User.Identity.GetUserName(); // Fails as null

因此，由于此API调用，似乎正在重置HttpContext对象.有什么想法要解决吗?

So it seems the HttpContext object is being reset due to this API call. Any thoughts how to fix this?

提前谢谢.

编辑/更多信息.

这是通过"PostAsync"发生的；也是

This happens with "PostAsync" as well.

var postContent = new FormUrlEncodedContent(post);
var userName = HttpContext.Current.User.Identity.GetUserName(); // returns value
var response = await client.PostAsync(IdentityUrl() + TokenEndPoint,postContent);
userName = HttpContext.Current.User.Identity.GetUserName(); // returns null
