带有标头属性的 BOT 框架 Directline API 调用

我想调用我的 BOT 框架 Directline API，并带有附加标头属性和直接线路机密。如何在我的 BOT 框架代码中提取它并将其放入 IBOTStore 以备将来使用。我想知道我是否可以在意图级别读取标题属性？

这是我解析 alexa API 请求的示例代码：

 var directLineSecret = ConfigurationManager.AppSettings["directlinesecret"];
        _client = new DirectlineClient(directLineSecret, "alexa" + Guid.NewGuid().ToString().Replace("-", ""));

var client = new HttpClient
        {
            BaseAddress = new Uri("https://directline.botframework.com")
        };

        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

        client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("BotConnector", _secret);
        client.DefaultRequestHeaders.Add("ETag", "*");
        client.DefaultRequestHeaders.Add("channel", _from);

        var response =
            await client.GetAsync("/api/tokens/", HttpCompletionOption.ResponseHeadersRead)
            .ConfigureAwait(false);
        response.EnsureSuccessStatusCode();

        response =
            await client.PostAsJsonAsync("/api/conversations/", new object())
            .ConfigureAwait(false);
        response.EnsureSuccessStatusCode();

        var conversationInfo =
            await response.Content.ReadAsAsync<JObject>()
            .ConfigureAwait(false);

        _conversationId = (string)conversationInfo["conversationId"];
        var scopedToken = (string)conversationInfo["token"];

        client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("BotConnector", scopedToken);

机器人框架

 public async Task None(IDialogContext context, LuisResult result)
    {
        try
        {...............}

感谢您的提前支持！！
