用戶離線時如何啟動從Bot到Skype for Business的出站郵件

Question

根據一個和兩個 ，我發現可以向用戶發送主動消息。 但是，當用戶離線時，它似乎不起作用。 可能嗎？

我正在使用C＃和bot框架V3。

我有兩個問題：

1. 即使用戶不在線也可以向用戶發送消息

2. 如果我使用下面的代碼（是兩個代碼），是否可以啟動對話框？ 如果是，怎么辦？

我的代碼如下

public class CustomWebAPIController : ApiController
{
    [HttpPost]

    [Route("api/CustomWebAPI")]
    public async Task<HttpResponseMessage> SendMessage([FromBody]string userobj)
    {
        try
        {

            //Initiate a Conversation
            string trustServiceUri = "https://api.skypeforbusiness.com/platformservice/botframework";
            MicrosoftAppCredentials.TrustServiceUrl(trustServiceUri);
            ConnectorClient connector = new ConnectorClient(new Uri(trustServiceUri));
            List<ChannelAccount> participants = new List<ChannelAccount>();
            participants.Add(new ChannelAccount("sip:XXXXX@XXXXX.onmicrosoft.com", "Agent"));
            ConversationParameters parameters = new ConversationParameters(true, new ChannelAccount("sip:XXXXXbot@XXXXX.onmicrosoft.com", "Bot"), participants, "TestTopic");
            ConversationResourceResponse response = connector.Conversations.CreateConversationAsync(parameters).Result;

            //Initiate another connector with the ServiceURL from above response.
            ConnectorClient connectorSend = new ConnectorClient(new Uri(response.ServiceUrl));
            IMessageActivity msg = Activity.CreateMessageActivity();
            msg.Recipient = new ChannelAccount("sip:XXXXX@XXXXX.onmicrosoft.com", "Agent");
            msg.Text = "text message";
            msg.Locale = "en-Us";
            msg.From = new ChannelAccount("sip:XXXXXbot@XXXXX.onmicrosoft.com", "Bot");
            msg.Type = ActivityTypes.Message;
            msg.Timestamp = DateTime.UtcNow;
            msg.ChannelId = "skypeforbusiness";
            msg.ServiceUrl = response.ServiceUrl;
            msg.Conversation = new ConversationAccount(isGroup: true, id: response.Id, name: null);
            //Send the message from Bot to User
            //var result = connectorSend.Conversations.SendToConversationAsync(msg.Conversation.Id, (Activity)msg).Result;
            await connector.Conversations.SendToConversationAsync((Activity)msg);

            var resp = new HttpResponseMessage(HttpStatusCode.OK);

            return resp;

        }
        catch (Exception ex)
        {
            return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ex);
        }
    }
}

您引用的第一個文檔指出：

只要用戶處於與機器人的用戶發起的對話中，並且仍打開Skype對話窗口

當前，這是Skype for Business Bots的限制（預覽）。
