Question

我在C＃中编写了一个使用pub / sub的环聊聊天机器人，因此我可以在防火墙一侧托管机器人。除了卡片内的交互式按钮外，一切似乎都运行良好。如果我创建一个具有特定操作方法名称的按钮，则bot会收到带有相应操作方法名称的CARD_CLICKED消息。但是，环聊聊天应用中的卡片似乎不知道是否发送了响应，因为在环聊聊天应用最终说“＃34;无法联系Bot”之前，机器人最终获得了三次CARD_CLICKED消息。稍后再试一次＆＃34;。我一直在使用NuGet的Google.Apis.HangoutsChat.v1和Google.Cloud.PubSub.V1软件包。

这是猜测，但似乎问题可能是交互式按钮无法通过pub / sub正常工作。任何帮助将不胜感激。

以下是我的代码片段：

SubscriptionName subscriptionName = new SubscriptionName(PROJECT_ID, SUBSCRIPTION_ID);
SubscriberServiceApiClient client = SubscriberServiceApiClient.Create();

GoogleCredential credential = GoogleCredential.FromFile(CREDENTIALS_PATH_ENV_PROPERTY).CreateScoped(HANGOUTS_CHAT_API_SCOPE);
HangoutsChatService chatService = new HangoutsChatService(new BaseClientService.Initializer
{
    ApplicationName = "My Bot",
    HttpClientInitializer = credential
});

while (true)
{
    PullResponse response = client.Pull(subscriptionName, false, 3, CallSettings.FromCallTiming(CallTiming.FromExpiration(Expiration.FromTimeout(TimeSpan.FromSeconds(90)))));

    if ((response.ReceivedMessages == null) || (response.ReceivedMessages.Count == 0))
        Console.WriteLine("Pulled no messages.");
    else
    {
        foreach (ReceivedMessage message in response.ReceivedMessages)
        {
            try
            {
                byte[] jsonBytes = message.Message.Data.ToByteArray();
                JObject json = JObject.Parse(Encoding.UTF8.GetString(jsonBytes));

                string messageType = (string)json["type"];
                switch (messageType)
                {
                    case "MESSAGE":
                    {
                        // Get text
                        string messageText = (string)json["message"]["text"];
                        Console.WriteLine($"[{messageType}] {messageText}");

                        // Send response
                        string spaceName = (string)json["space"]["name"];
                        SpacesResource.MessagesResource.CreateRequest request = chatService.Spaces.Messages.Create(new Message
                        {
                            Cards = new[]
                            {
                                new Card
                                {
                                    Header = new CardHeader
                                    {
                                        Title = "Message Received!"
                                    },

        // Acknowledge the message so we don't see it again.
        string[] ackIds = new string[response.ReceivedMessages.Count];
        for (int i = 0; i < response.ReceivedMessages.Count; ++i)
            ackIds[i] = response.ReceivedMessages[i].AckId;
        client.Acknowledge(subscriptionName, ackIds);
    }
}

在环聊聊天API中使用按钮需要自定义答案，包括：

{
    'thread': {
        'name': thread_id
    },
    'actionResponse': {
        'type': 'UPDATE_MESSAGE'
    }
}

我建议将环聊聊天API与机器人网址一起使用。

使用pub / sub时，交互式按钮无法正常工作
