【问题描述】:
我正在使用 QnA 模板 (Microsoft Azure) 制作聊天机器人。基本上,用户提出问题,机器人将尝试在常见问题解答文档中找到答案。如果失败,我希望它使用用户的查询运行 Bing 搜索并以最准确的答案回复。我发现了这个使用 Bing Web Search API 的示例:https://docs.microsoft.com/en-us/azure/cognitive-services/bing-web-search/quickstarts/nodejs。现在,我只想让机器人回复搜索的第一个链接。 但是,我不知道如何将链接中的代码与生成的 QnA Bot 代码(在 Node.js 中)合并:
var restify = require('restify');
var builder = require('botbuilder');
var botbuilder_azure = require("botbuilder-azure");
var builder_cognitiveservices = require("botbuilder-cognitiveservices");
var request = require('request');
// Setup Restify Server
var server = restify.createServer();
server.listen(process.env.port || process.env.PORT || 3978, function () {
console.log('%s listening to %s', server.name, server.url);
});
// Create chat connector for communicating with the Bot Framework Service
var connector = new builder.ChatConnector({
appId: process.env.MicrosoftAppId,
appPassword: process.env.MicrosoftAppPassword,
openIdMetadata: process.env.BotOpenIdMetadata
});
// Listen for messages from users
server.post('/api/messages', connector.listen());
var tableName = 'botdata';
var azureTableClient = new botbuilder_azure.AzureTableClient(tableName, process.env['AzureWebJobsStorage']);
var tableStorage = new botbuilder_azure.AzureBotStorage({ gzipData: false }, azureTableClient);
// Create your bot with a function to receive messages from the user
var bot = new builder.UniversalBot(connector);
bot.set('storage', tableStorage);
// Recognizer and and Dialog for GA QnAMaker service
var recognizer = new builder_cognitiveservices.QnAMakerRecognizer({
knowledgeBaseId: process.env.QnAKnowledgebaseId,
authKey: process.env.QnAAuthKey || process.env.QnASubscriptionKey, // Backward compatibility with QnAMaker (Preview)
endpointHostName: process.env.QnAEndpointHostName
});
var basicQnAMakerDialog = new builder_cognitiveservices.QnAMakerDialog({
recognizers: [recognizer],
defaultMessage: 'Sorry, I cannot find anything on that topic',
qnaThreshold: 0.3
});
// Override the invokeAnswer function from QnAMakerDialog
builder_cognitiveservices.QnAMakerDialog.prototype.invokeAnswer = function (session, recognizeResult, threshold, noMatchMessage) {
var qnaMakerResult = recognizeResult;
session.privateConversationData.qnaFeedbackUserQuestion = session.message.text;
if (qnaMakerResult.score >= threshold && qnaMakerResult.answers.length > 0) {
if (this.isConfidentAnswer(qnaMakerResult) || this.qnaMakerTools == null) {
this.respondFromQnAMakerResult(session, qnaMakerResult);
this.defaultWaitNextMessage(session, qnaMakerResult);
}
else {
this.qnaFeedbackStep(session, qnaMakerResult);
}
}
else {
this.noMatch(session, noMatchMessage, qnaMakerResult);
}
};
// API call to Bing
basicQnAMakerDialog.noMatch = function (session, noMatchMessage, qnaMakerResult) {
var term = session.message.text;
var key = 'i hid it';
var options = {
url: "https://api.cognitive.microsoft.com/bing/v7.0/search?q=" + term,
method: 'GET',
headers : {
'Ocp-Apim-Subscription-Key' : key
}
};
request(options, function(err,res, body){
if(err){
console.error(err);
session.send(noMatchMessage);
}
body = JSON.parse(body);
session.send("I found a thing: " + body["webPages"]["value"][0]["name"]);
});
};
bot.dialog('basicQnAMakerDialog', basicQnAMakerDialog);
bot.dialog('/', //basicQnAMakerDialog);
[
function (session, results) {
session.replaceDialog('basicQnAMakerDialog');
},
]);
在bot.dialog里面的函数中,我想我应该添加一个条件,比如:如果bot返回默认消息,打开一个网页,让要搜索的“term”成为用户的最后一条消息。但是,我不知道如何准确编码,以及在哪里编码。另外,我不知道如何退出 replaceDialog 函数,以便回复默认消息或常见问题解答中的答案以外的其他内容。
PS:总的来说,我对 javascript 或 Web 开发没有太多经验。任何帮助将不胜感激:)
