发布后不会触发 ConversationUpdate

Question

您好，我在 C# 中使用 Microsoft BotFramework 创建了我的第一个测试机器人。在 private async Task< Activity > HandleSystemMessage(Activity message) 在 if (message.Type == ActivityTypes.ConversationUpdate) 通常它应该通知添加到组的新成员或有人在 Telegram Messenger 中点击机器人的开始按钮。当我使用 BotFramework 模拟器在调试模式下测试它时，一切正常，但在我发布它之后，我发现在 Telegram Messenger 中点击开始按钮后，我的代码没有运行。我的代码在 ActivationType.ConversationUpdate

foreach (var item in message.MembersAdded)
                {
    try
    {
        using (var dbcontext = new WatermarkBotDBEntities())
        {
            dbcontext.BotUsers.Add(new BotUser()
            {
               AddedFriends = 0,
               ConversationID = message.Conversation.Id,
               ServiceUrl = message.ServiceUrl,
               UserID = message.From.Id
            });
         dbcontext.SaveChanges();
         if (Request.RequestUri.Query != "")
         {
             var u = dbcontext.BotUsers.Where(x => x.BotSalCode == Request.RequestUri.Query.Replace("?start=", string.Empty)).FirstOrDefault();
             u.AddedFriends++;
             dbcontext.Entry(u).State = System.Data.Entity.EntityState.Modified;
             if (u != null)
             {
                 var connector = new ConnectorClient(new Uri(u.ServiceUrl));
                 IMessageActivity newMessage = Activity.CreateMessageActivity();
                 newMessage.Type = ActivityTypes.Message;
                //newMessage.From = new ChannelAccount("<BotId>", "<BotName>");
                newMessage.From = new ChannelAccount("c3e7mhdafcecn7ng3", "Bot");
                newMessage.Conversation = new ConversationAccount(false, u.ConversationID);
                newMessage.Recipient = new ChannelAccount(u.UserID);
                if (u.AddedFriends <= 2)
                    newMessage.Text = $"SomeText.";
                else newMessage.Text = "SomeTex";
                await connector.Conversations.SendToConversationAsync((Activity)newMessage);
                 dbcontext.SaveChanges();
           }
        }
    }
}
catch (Exception ex)
{
}

那么如何在电报中检测到命中开始呢？此致

我知道这不是一个完整的答案，但我想与您分享这段代码以防它可能有所帮助。以下是发送欢迎消息的推荐方式，您可以重新使用此代码。

else if (message.Type == ActivityTypes.ConversationUpdate || message.Type == ActivityTypes.Message)
            {
                IConversationUpdateActivity iConversationUpdated = message as IConversationUpdateActivity;
                if (iConversationUpdated != null)
                {
                    ConnectorClient connector = new ConnectorClient(new System.Uri(message.ServiceUrl));

                    foreach (var member in iConversationUpdated.MembersAdded ?? System.Array.Empty<ChannelAccount>())
                    {
                        // if the bot is added, then
                        if (member.Id == iConversationUpdated.Recipient.Id)
                        {
                            var reply = ((Activity)iConversationUpdated).CreateReply(
                            $"Hi! I'm Botty McBot.");
                            await connector.Conversations.ReplyToActivityAsync(reply);
                        }
                    }
                }
            }

这是我经过大量测试后为我的问题找到的答案：在 BotFramework 应用程序中默认定义的 public async Task<HttpResponseMessage> Post([FromBody]Activity activity) 函数中的 MessagesController class 中，您必须执行如下操作：

if (activity.Type == ActivityTypes.Message)
{
    if (activity.Text.StartsWith("/start"))
    {
        //This will return you the start parameter of a link like : http://telegram.me/botname?start=Parameter
        var Parameter = activity.Text.Replace("/start ", "");
    }
}
