从 azure 部署的机器人向 MS 团队发送主动消息

我已经将机器人部署到 azure，当连接到 azure 中的 MS 团队频道时，我能够 ping 机器人并接收消息，这很好。 我还在机器人中添加了主动消息传递，其中通道中每隔一分钟就会触发一条消息。

它在模拟器中工作，但在网络聊天和 MS 团队中不起作用： 通知控制器未被触发。

你能帮我一下吗？ 我已将代码上传至GITHUB：https://github.com/nivinsuna Three/Botv4.git https://github.com/nivinsunathree/Botv4.git

public override async Task OnTurnAsync(ITurnContext turnContext, CancellationToken cancellationToken = default(CancellationToken))
{
    await base.OnTurnAsync(turnContext, cancellationToken);


    System.Timers.Timer checkForTime = new System.Timers.Timer(interval60Minutes);
    checkForTime.Elapsed += new ElapsedEventHandler(checkForTime_Elapsed);
    checkForTime.Enabled = true;


    // Save any state changes that might have occured during the turn.
    await _conversationState.SaveChangesAsync(turnContext, false, cancellationToken);
    await _userState.SaveChangesAsync(turnContext, false, cancellationToken);
}

void checkForTime_Elapsed(object sender, ElapsedEventArgs e)
{
    bool timeIsReady = true;
    if (timeIsReady == true)
    {
        var url = "http://localhost:3978/api/notify";

        try
        {
            Process.Start(url);
        }
        catch
        {
            // hack because of this: https://github.com/dotnet/corefx/issues/10361
            if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
            {
                url = url.Replace("&", "^&");
                Process.Start(new ProcessStartInfo("cmd", $"/c start {url}") { CreateNoWindow = false });
            }
            else if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux))
            {
                Process.Start("xdg-open", url);
            }
            else if (RuntimeInformation.IsOSPlatform(OSPlatform.OSX))
            {
                Process.Start("open", url);
            }
            else
            {
                throw;
            }
        }
    }
}

一分钟后，它应该在频道中触发以下消息：

await turnContext.SendActivityAsync(MessageFactory.Text($"Hello!" + Environment.NewLine + $"Trust you are well" + Environment.NewLine + $"Hope that you are having a good day" + Environment.NewLine + $"We are contacting you concerning lea access requests" + Environment.NewLine + $"Could you please review the following tasks if any and add the required information!"), cancellationToken);
//await turnContext.SendActivityAsync(MessageFactory.Text($"Please type ok to continue!"), cancellationToken);
await turnContext.SendActivityAsync(MessageFactory.Text("Could you please click on the below button to continue?"));

var card = new HeroCard
{
    //Text = "Could you please click on the below button to continue?",
    Buttons = new List<CardAction>
        {
            new CardAction(ActionTypes.ImBack, title: "lea access request", value: "lea access request"),
        },
};
var reply = MessageFactory.Attachment(card.ToAttachment());
await turnContext.SendActivityAsync(reply, cancellationToken);

我通过电子邮件提到了这一点，但我会在这里为其他人重新发布：

您的主动消息传递在模拟器中有效，但在团队中无效，因为您只添加了一个ConversationReference in EchoBot.OnConversationUpdateActivityAsync.

正如所解释的here https://stackoverflow.com/questions/55517906/how-do-i-send-a-11-welcome-message/55525014#55525014，Teams 仅在安装机器人或用户第一次与机器人交谈时发送 ConversationUpdate。Here https://stackoverflow.com/questions/57304988/how-to-send-a-conversationupdate-to-microsoft-teams-from-bot-manually/57315460#57315460是一种可以测试它的方法。
