我开始学习Microsoft Bot Framework,但是当我尝试使用Connector时,它总是返回：

“message”: “An error has occurred.”,
“exceptionMessage”: “Unable to deserialize the response.”,
“exceptionType”: “Microsoft.Rest.RestException”,

这是代码

  public async Task<Message> Post([FromBody]Message message)
    {
        try
        {
            if (message.Type == "Message")
            {
                // calculate something for us to return
                //int length = (message.Text ?? string.Empty).Length;

                // return our reply to the user
                //                return message.CreateReplyMessage($"You sent {length} characters");

                //var counter = message.GetBotPerUserInConversationData<int>("counter");

                //// create a reply message   
                //Message replyMessage = message.CreateReplyMessage($"{++counter} You said:{message.Text}");

                //// save our new counter by adding it to the outgoing message
                //replyMessage.SetBotPerUserInConversationData("counter", counter);

                //// return our reply to the user
                ////return replyMessage;

                //                return message.CreateReplyMessage("Yo, I got it.", "en");
                // var replyMessage = message.CreateReplyMessage("Yo, I heard you.", "en");
                // var connectorr = new ConnectorClient();
                // connectorr.BaseUri = new Uri("http://localhost:3978/");

                //return await connectorr.Messages.SendMessageAsync(replyMessage);


                var connector = new ConnectorClient();
                connector.BaseUri = new Uri("http://localhost:3978/api/messages");

               await connector.Messages.SendMessageAsync(message.CreateReplyMessage($"You said:{message.Text}"));
              await  connector.Messages.SendMessageAsync(message.CreateReplyMessage("Yo 2.", "en"));
              await  connector.Messages.SendMessageAsync(message.CreateReplyMessage("Yo 3.", "en"));

                return null;
            }
            else
            {
                return HandleSystemMessage(message);
            }

        }
        catch (Exception ex)
        {

            throw;
        }
    }

最佳答案 您应该将其升级到最新版本3.8.0.
