如何在 OpenIdConnectEvents.OnAuthorizationCodeReceived 中访问用户的 HttpContext？

Question

在 ASP.NET Core 应用程序中，我有如下代码：

public void ConfigureServices(IServiceCollection services)
{
    services.AddAuthentication(options => ...)
    .AddCookie()
    .AddOpenIdConnect(options =>
    {
        ...
        options.Events = new OpenIdConnectEvents
        {
            ...
            OnAuthorizationCodeReceived = async context =>
            {
                // Here I want to access the user HttpContext. previously System.Web.HttpContext.Current
            }
        };
    });
    ...
}


}

我需要访问当前用户HttpContext 的原因是我正在处理一些在用户会话中缓存访问令牌的AuthenticationContext.AcquireTokenByAuthorizationCodeAsync 逻辑。以前版本的代码使用了System.Web.HttpContext.Current，据我了解，它已从 ASP.NET Core 中删除。 AuthorizationCodeReceivedContext.HttpContext 显然不是我要找的。​​p>

OnAuthorizationCodeReceived 委托的 context 参数包含保存当前 http 上下文的 HttpContext 属性

OnAuthorizationCodeReceived = async context =>
{
    var httpContext = context.HttpContext;
    //..
}
