如何在Bot框架中从Bot向多客户端发送消息

Question

问候每一个人！我是Microsoft Bot Framework的新成员，我想知道我们如何从Bot向多个客户端发送消息（不使用聊天组）？请给我一些建议。谢谢 还有一个问题是，当客户端关闭浏览器以便在客户端再次返回时检索对话时，我们如何保存Bot和客户端之间的对话？

Answer 1

阅读文档后，我认为有一种方法CreateConversation()方法可以向多个客户发送电子邮件。

但我认为你可以在for循环中使用CreateDirectConversation()方法，迭代你的用户帐户。这将启动与所有用户帐户的1：1对话。

Answer 2

取自Microsoft Bot Framwork SDK Reference: Starting Conversations

开始对话

要发起对话，您需要调用CreateConversation()或CreateDirectConversation()方法从频道获取ConversationAccount条记录。获得ConversationAccount之后，您可以在对SendToConversation()的消息调用中使用它。

创建1：1对话

CreateDirectConversation()方法用于在机器人和用户之间创建私人1：1对话。

要初始化ConnectorClient，请使用先前消息中保留的ServiceUrl

示例：

var userAccount = new ChannelAccount(name: "Larry", id: "@UV357341");
var connector = new ConnectorClient(new Uri(incomingMessage.ServiceUrl));
var conversationId = await connector.Conversations.CreateDirectConversationAsync(botAccount, userAccount);
IMessageActivity message =  Activity.CreateMessageActivity();
message.From = botAccount;
message.Recipient = userAccount;
message.Conversation = new ConversationAccount(id: conversationId.Id);
message.Text = "Hello";
message.Locale = "en-Us";
await connector.Conversations.SendToConversationAsync((Activity)message); 

创建群组对话

CreateConversation()方法用于创建新的群组对话。

  

注意：目前，电子邮件是支持机器人发起的群组对话的唯一渠道

示例：

var connector = new ConnectorClient(new Uri(incomingMessage.ServiceUrl));
List<ChannelAccount> participants = new List<ChannelAccount>();
participants.Add(new ChannelAccount("joe@contoso.com", "Joe the Engineer"));
participants.Add(new ChannelAccount("sara@contso.com", "Sara in Finance"));
ConversationParameters cpMessage = new ConversationParameters(message.Recipient, true, participants, "Quarter End Discussion");
var conversationId = await connector.Conversations.CreateConversationAsync(cpMessage);
IMessageActivity message = Activity.CreateMessageActivity();
message.From = botAccount;
message.Recipient = new ChannelAccount("lydia@contoso.com", "Lydia the CFO"));
message.Conversation = new ConversationAccount(id: conversationId.Id);
message.ChannelId = incomingMessage.ChannelId;
message.Text = "Hey, what's up everyone?";
message.Locale = "en-Us";
await connector.Conversations.SendToConversationAsync((Activity)message);
