C# 使用accesstoken/AuthenticationResult（如中间件中的UseCookieAuthentication（）手动设置cookie

在控制器中的操作中，我们拥有包含AccessToken的AuthenticationResult

我们希望使用此令牌进行手动登录，该令牌等同于UserCookieAuthentication owin中间件。可能吗

public partial class Startup
{
    public void ConfigureAuth(IAppBuilder app)
    {
        app.UseCookieAuthentication(new CookieAuthenticationOptions());
        app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);

        app.UseWindowsAzureActiveDirectoryBearerAuthentication(
            new WindowsAzureActiveDirectoryBearerAuthenticationOptions
            {
                Tenant = ConfigurationManager.AppSettings["ida:Tenant"],
                TokenValidationParameters = new TokenValidationParameters
                {
                ValidAudience = ConfigurationManager.AppSettings["ida:Audience"]
            },
            });
    }
}

我一直在查看HttpContext.GetOwinContext（）.Authentication.SignIn（），但这不需要任何令牌。

在Katana/Owin Github项目中，以下令牌助手使用AuthenticationResponseGrant方法解决了此问题：

                result = await authContext.AcquireTokenAsync(resource, clientId, uc);

                var principal = await new TokenHelper().GetValidatedClaimsPrincipalAsync(result.AccessToken);

                var claimsIdentity = new ClaimsIdentity(principal.Claims, CookieAuthenticationDefaults.AuthenticationType);

                var properties = new AuthenticationProperties();

                HttpContext.GetOwinContext().Authentication.AuthenticationResponseGrant =
                    new AuthenticationResponseGrant(claimsIdentity, properties);
