尝试使用std :: function和std :: bind绑定方法时遇到问题.

在我的CommunicationService类中:

this->httpServer->BindGET(std::bind(&CommunicationService::ManageGETRequest, this, std::placeholders::_1));

CommunicationService :: ManageGetRequest签名:

MessageContent CommunicationService::ManageGetRequest(std::string uri, MessageContent msgContent)

BindGET签名:

void RESTServer::BindGET(RequestFunction getMethod)

RequestFunction typedef:

typedef std::function<MessageContent(std::string, MessageContent)> RequestFunction;

BindGET上的错误:

错误C2664:'void RESTServer :: BindGET(RequestFunction)':无法从'std :: _ Binder <std :: _ Unforced,MessageContent(__cdecl communication :: CommunicationService ::*)(std :: string,MessageContent)转换参数1, communication :: CommunicationService*const,const std :: _ Ph <1>&>'to'RequestFunction'

之前,我的RequestFunction是这样的:

typedef std::function<void(std::string)> RequestFunction;

它工作得很好.(当然,调整了所有签名方法).

我不明白导致错误的原因.

我正在尝试通过DirectLineClient库将活动发送到我的机器人：

        var directLineClient = new DirectLineClient($"{secret}");
        directLineClient.BaseUri = new Uri($"https://directline.botframework.com/");

        var conversation = await directLineClient.Conversations.StartConversationAsync().ConfigureAwait(false);
        var activity = new Microsoft.Bot.Connector.DirectLine.Activity();
        activity.From = new Microsoft.Bot.Connector.DirectLine.ChannelAccount();
        activity.From.Name = "Morgan";
        activity.Text = message;
        activity.Type = "message";

        var resourceResponse = await directLineClient.Conversations.PostActivityAsync(conversation.ConversationId, activity).ConfigureAwait(false);
        await ReadBotMessagesAsync(directLineClient, conversation.ConversationId);

resourceResponse始终为null。

我添加了一种方法来等待机器人的响应：

    private static async Task ReadBotMessagesAsync(DirectLineClient client, string conversationId)
    {
        string watermark = null;

        while (true)
        {
            var activitySet = await client.Conversations.GetActivitiesAsync(conversationId, watermark);
            watermark = activitySet?.Watermark;

            foreach (Microsoft.Bot.Connector.DirectLine.Activity activity in activitySet.Activities)
            {
                Console.WriteLine(activity.Text);

                if (activity.Attachments …
