Question

我正在尝试为我的机器人/网页设置一个反向通道，以便我可以在两者之间发送事件。我添加了此问题Bot framework get the ServiceUrl of embedded chat control page

中显示的示例

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不存在。我是否需要一个特殊的软件包来处理使用bot框架的反向通道？

Answer 1

根据您的评论，您似乎使用的是旧版本的BotBuilder nuget包;这就是为什么你没有这些属性/价值观。

请更新到最新版本的BotBuilder v3.5.5，这样就可以了。

BackChannel通信不存在ActivityTypes.Event
