將Microsoft QnA Maker連接到Bot Framework

Question

我已經使用QnA Maker創建了一個bot並設置了一個FB應用程序連接到我們的FB頁面和Microsoft Bot Framework。但是，缺少一些東西。我如何將Microsoft QnA製造商連接到Bot Framework？ （FWIW--目標是一個FB信使機器人，它回答有關非贏利事件的FAQ）。謝謝

Answer 1

您不能直接將QnAMaker端點鏈接到FB。您首先需要使用QnAMaker模板創建一個Bot服務，然後在FB通道上啓用它。請參閱https://docs.microsoft.com/en-us/bot-framework/azure/azure-bot-service-quickstart

Answer 2

您需要註冊QNA製造商並使用下面的代碼來獲取響應。無需在bot框架上註冊。

string responseString = string.Empty; 

var query = 「hi」; //User Query 
var knowledgebaseId = 「YOUR_KNOWLEDGE_BASE_ID」; // Use knowledge base id created. 
var qnamakerSubscriptionKey = 「YOUR_SUBSCRIPTION_KEY」; //Use subscription key assigned to you. 

//Build the URI 
Uri qnamakerUriBase = new Uri("https://westus.api.cognitive.microsoft.com/qnamaker/v1.0"); 
var builder = new UriBuilder($"{qnamakerUriBase}/knowledgebases/{knowledgebaseId}/generateAnswer"); 

//Add the question as part of the body 
var postBody = $"{{\"question\": \"{query}\"}}"; 

//Send the POST request 
using (WebClient client = new WebClient()) 
{ 
    //Set the encoding to UTF8 
    client.Encoding = System.Text.Encoding.UTF8; 

    //Add the subscription key header 
    client.Headers.Add("Ocp-Apim-Subscription-Key", qnamakerSubscriptionKey); 
    client.Headers.Add("Content-Type", "application/json"); 
    responseString = client.UploadString(builder.Uri, postBody); 
}

using Newtonsoft.Json; 

private class QnAMakerResult 
{ 
    /// <summary> 
    /// The top answer found in the QnA Service. 
    /// </summary> 
    [JsonProperty(PropertyName = "answer")] 
    public string Answer { get; set; } 

    /// <summary> 
    /// The score in range [0, 100] corresponding to the top answer found in the QnA Service. 
    /// </summary> 
    [JsonProperty(PropertyName = "score")] 
    public double Score { get; set; } 
} 
//De-serialize the response 
QnAMakerResult response; 
try 
{ 
    response = JsonConvert.DeserializeObject<QnAMakerResult>(responseString); 
} 
catch 
{ 
    throw new Exception("Unable to deserialize QnA Maker response string."); 
}
