node.js - 尝试将 Microsoft QnA 制造商服务与 Bot Framework 连接，但未从我的机器人那里得到任何回复

我是 Microsoft bot 框架的新手，正在尝试使用 QnA maker 构建基本 bot

但我被困在将 QnA 制造商服务与app.js.

没有得到 QnA 制造商的回复。

应用程序.js

const restify = require('restify');
const builder = require('botbuilder');
const cognitiveServices = require('botbuilder-cognitiveservices');
//connecting to server

const server = restify.createServer();
server.listen(process.env.port || process.env.PORT || 3978,
    function () {
        console.log('%s listening to %s',server.name,server.url);
    }
);

const connector = new builder.ChatConnector({
    appId: process.env.MicrosoftAppId,
    appPassword: process.env.MicrosoftAppPassword
});
//listening post from server
server.post('/api/messages', connector.listen());

var bot = new builder.UniversalBot(connector);

const recognizer = new cognitiveServices.QnAMakerRecognizer({
    knowledgeBaseId: "ffek8d39-dldc-48df-a9db-d902efc18cda",
    subscriptionKey: "881jc9eb-1a5b-4a10-bi89-233afh83ce98",
});

const qnaMakerDialog = new cognitiveServices.QnAMakerDialog({
    recognizers: [recognizer],
    defaultMessage: "Sorry I don't understand the question",
    qnaThreshold: 0.4,
});

bot.dialog('/', qnaMakerDialog);

Answer 1

QnAMaker 当前处于 GA 版本，不再处于预览状态。这看起来并不多，但它确实意味着单个识别器变量的区别：endpointHostName。

您目前拥有：

const recognizer = new cognitiveServices.QnAMakerRecognizer({
    knowledgeBaseId: "kbid",
    subscriptionKey: "subKey"
});

相反，它应该如下所示：

const recognizer = new cognitiveServices.QnAMakerRecognizer({
    knowledgeBaseId: "kbid",
    authKey: "subKey",
    endpointHostName: "https://NAMEOFMYQNABOTHERE.azurewebsites.net/qnamaker"
});

端点在 QnAMaker.ai 的代码片段中列为“HOST”。

至于您没有收到任何回复的原因，那是因为您没有必要的代码让您的机器人告诉您它不知道您在谈论哪个 QnAMaker 知识库。对最终的 bot.dialog 部分稍作改动将对此有所帮助。

bot.dialog('qnaMakerDialog', qnaMakerDialog);    

bot.dialog('/', 
    [
        function (session) {
            var qnaKnowledgebaseId = "kbid";
            var qnaAuthKey = "subKey";
            var endpointHostName = "https://NAMEOFMYQNABOTHERE.azurewebsites.net/qnamaker";

            // QnA Subscription Key and KnowledgeBase Id null verification
            if ((qnaAuthKey == null || qnaAuthKey == '') || (qnaKnowledgebaseId == null || qnaKnowledgebaseId == ''))
                session.send('Please set QnAKnowledgebaseId, QnAAuthKey and QnAEndpointHostName (if applicable) in App Settings. Learn how to get them at https://aka.ms/qnaabssetup.');
            else {
                    session.replaceDialog('qnaMakerDialog');
            }
        }
    ]);

这样，如果其中任何一个丢失或不正确，您的机器人将返回上面显示的预设消息，让您知道缺少某些内容。

快乐编码！
