V4 Bot Framework CreateConversationAsync（ConversationReference 已過時）

Question

下面的代碼有效 - 當新用戶添加到 Teams 頻道時，機器人會向用戶個人而不是整個頻道發送歡迎消息。 由於某種原因，它不再起作用——我相信它與CreateConversationAsync()方法有關。 V4 文檔 state： “此方法現已過時，因為 ConversationReference 參數現在是多余的。使用沒有此參數的重載。” 但我一直無法弄清楚如何正確更新下面的代碼以使其正常工作。

CreateConversationAsync：（此方法將對話引用（現已過時）傳遞給 ContinueConversationAsync()）

ConversationReference conversationReference = null;
return await ((BotFrameworkAdapter)turnContext.Adapter).CreateConversationAsync(
  teamsChannelId,
  serviceUrl,
  credentials,
  conversationParameters,
  async (t1, c1) =>
  {
    conversationReference = t1.Activity.GetConversationReference();
    await Task.FromResult(false).ConfigureAwait(false);
  }, cancellationToken).ContinueWith(_ => { return conversationReference; }).ConfigureAwait(false);

繼續對話異步：

 if (conversationReference != null)
 {
    await turnContext.Adapter.ContinueConversationAsync(
      BotAppId,
      conversationReference,
      async (t2, c2) =>
      {
        await t2.SendActivityAsync(MessageFactory.Text(messages[0]), cancellationToken: c2).ConfigureAwait(false);
      },cancellationToken).ConfigureAwait(false);
}

ConversationParameters供參考：

var conversationParameters = new ConversationParameters
{
  IsGroup = false,
  Bot = this.TeamsHelper.GetRecipient(turnContext),
  Members = new List<ChannelAccount>() { member },
  TenantId = this.TeamsHelper.GetChannelTennantId(channelData),
  TopicName = "Testing",
};

任何幫助將不勝感激！

------ 用代碼片段更新 ------

            var teamsChannelId = turnContext.Activity.TeamsGetChannelId();
            var serviceUrl = turnContext.Activity.ServiceUrl;
            var credentials = new MicrosoftAppCredentials(BotAppId, BotAppPassword);
            var channelData = turnContext.Activity.GetChannelData<TeamsChannelData>();

            var conversationParameters = new ConversationParameters
            {
                IsGroup = false,
                Bot = turnContext.Activity.Recipient,
                Members = new List<ChannelAccount>() { member },
                //TenantId = turnContext.Activity.Conversation.TenantId,
                TenantId = channelData.Tenant.Id,
                TopicName = "Testing Topic ",
            };

            var conversationReference = new ConversationReference()
            {
                ChannelId = teamsChannelId,
                Bot = turnContext.Activity.Recipient,
                ServiceUrl = serviceUrl,
                Conversation = new ConversationAccount() { ConversationType = "channel", IsGroup = false, Id = teamsChannelId, TenantId = channelData.Tenant.Id },
            };

            await ((BotFrameworkAdapter)turnContext.Adapter).CreateConversationAsync(
                           teamsChannelId,
                           serviceUrl,
                           credentials,
                           conversationParameters,
                           async (t1, c1) =>
                           {
                               await ((BotFrameworkAdapter)turnContext.Adapter).ContinueConversationAsync(
                                   BotAppId,
                                   conversationReference,
                                   async (t2, c2) =>
                                   {
                                       await t2.SendActivityAsync(MessageFactory.Text("This will be the first response to the new thread"), c2).ConfigureAwait(false);
                                   },
                                   cancellationToken).ConfigureAwait(false);
                           },
                           cancellationToken).ConfigureAwait(false);

想用我得到的建議更新每個人：

如果您想親自向用戶發送消息，您需要傳遞該 1:1 聊天的對話 ID 而不是頻道，因此，對話引用應該是這樣的（請參閱CreateConversationAsync 中的變量 conversationReference ）：

await ((BotFrameworkAdapter)turnContext.Adapter).CreateConversationAsync(
    "msteams",
    serviceUrl,
    credentials,
    conversationParameters,
    async (t1, c1) =>
    {
        var userConversation = t1.Activity.Conversation.Id;
        var conversationReference = new ConversationReference
        {
            ServiceUrl = serviceUrl,
            Conversation = new ConversationAccount
            {
                Id = userConversation,
            },
        };
        await ((BotFrameworkAdapter)turnContext.Adapter).ContinueConversationAsync(
            BotAppId,
            conversationReference,
            async (t2, c2) =>
            {
                await t2.SendActivityAsync(MessageFactory.Text("This will be the first response to the new thread"), c2).ConfigureAwait(false);
            },
            cancellationToken).ConfigureAwait(false);
    },
    cancellationToken).ConfigureAwait(false);

我能夠在本地測試這種方法，它奏效了！
