Code changes discussion

In order to invoke the Bing Search API, utilized the azure-cognitiveservices-websearch npm package. The request/ response management is more streamlined by this. The source code can be found here, and the repo here.

var websearchAPIClient = require('azure-cognitiveservices-websearch');
var msrestazure = require('ms-rest-azure');
..
..
        // pass Bing Search API key, and get a new object for type CognitiveServicesCredentials
        var credentials = new msrestazure.CognitiveServicesCredentials(process.env.BingSeachApiKey);

        // pass CognitiveServicesCredentials, get a new search client object
        var searchAPIClient = new websearchAPIClient(credentials);

        searchAPIClient.web.search(session.message.text)
            .then((result) => {
                var properties = ["news"]; //["images", "webPages", "news"];
                for (let index = 0; index < properties.length; index++) {
                    if (result[properties[index]]){
                        //console.log(result[properties[index]].value);
                        var botResults = result[properties[index]].value
                                                .map(item => item.name + ' :: ' + item.url);
                        session.endDialog(JSON.stringify(botResults));
                    } else {
                        console.log(`No ${properties[index]} data`);
                    }               
                }
            }).catch((err) => {
            console.log(err);
        });
