c# - BackChannel通讯不存在ActivityTypes.Event

我试图在我的漫游器/网页上建立反向通道，以便可以在两者之间发送事件。我已经添加了此问题中显示的示例Bot framework get the ServiceUrl of embedded chat control page

public async Task<HttpResponseMessage> Post([FromBody]Activity activity)
{
    if (activity.Type == ActivityTypes.Event &&
        string.Equals(activity.Name, "buttonClicked", StringComparison.InvariantCultureIgnoreCase))
    {
        ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl));

        // return our reply to the user
        Activity reply = activity.CreateReply("I see that you just pushed that button");
        await connector.Conversations.ReplyToActivityAsync(reply);
    }

    if (activity.Type == ActivityTypes.Message)
    {
        ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl));

        // return our reply to the user
        var reply = activity.CreateReply();
        reply.Type = ActivityTypes.Event;
        reply.Name = "changeBackground";
        reply.Value = activity.Text;
        await connector.Conversations.ReplyToActivityAsync(reply);
    }
    else
    {
        HandleSystemMessage(activity);
    }
    var response = Request.CreateResponse(HttpStatusCode.OK);
    return response;
}

但是，ActivityTypes.Event和activity.Name都不存在。我需要一个特殊的程序包来处理Bot框架的反向通道吗？

最佳答案

根据您的评论，似乎您使用的是BotBuilder nuget软件包的旧版本；这就是为什么您没有这些属性/值。

请更新到最新版本的BotBuilder v3.5.5即可。
