Question

我刚刚根据[SDK参考]中发布的示例开发了一个演示skype调用bot。我在Azure中发布了该项目，并在skype频道的门户网站上注册，更新了相关页面。如果我在Skype上与机器人聊天，一切都运行正常，但如果我尝试skype通话，而不是我所期待的消息，我会收到一条语音消息“无法与该项目通话，但我们正在努力”。这是因为正在进行审批流程还是我错过了一些步骤？

这是CallingController代码：

using Microsoft.Bot.Builder.Calling.Events;
using Microsoft.Bot.Builder.Calling.ObjectModel.Contracts;
using Microsoft.Bot.Builder.Calling.ObjectModel.Misc;

using System.IO;
using System.Threading.Tasks;
using System.Web;

        public ICallingBotService CallingBotService
        {
            get; private set;
        }

        public SimpleCallingBot(ICallingBotService callingBotService)
        {
            if (callingBotService == null)
                throw new ArgumentNullException(nameof(callingBotService));
            this.CallingBotService = callingBotService;

Answer 1

根据您的评论，我认为问题在于启用Skype频道时使用的网址。在Bot Framework的Skype设置中配置的Calling WebHook URL应该基于您的网址https://skyva.azurewebsites.net/api/calling/call。

您的CallingController应如下：

[BotAuthentication]
[RoutePrefix("api/calling")]
public class CallingController : ApiController
{
    public CallingController() : base()
    {
        CallingConversation.RegisterCallingBot(callingBotService => new SimpleCallingBot(callingBotService));
    }

    [Route("callback")]
    public async Task<HttpResponseMessage> ProcessCallingEventAsync()
    {
        return await CallingConversation.SendAsync(this.Request, CallRequestType.CallingEvent);
    }

    [Route("call")]
    public async Task<HttpResponseMessage> ProcessIncomingCallAsync()
    {
        return await CallingConversation.SendAsync(this.Request, CallRequestType.IncomingCall);
    }
}

我解决了这个问题，在skype bot配置中我必须指定调用端点而不是回调。现在机器人正常工作。
