А вообще, как-то так делается:

function parseUrl(url) {
    return new Promise((resolve, reject) => {
        request.get(url, (err, res, body) => {
            if (err) {
                reject(err);
                return;
            }
            
            resolve(body);
        })
    });
}

let urls = ["http://javascript.ru", "http://habrahabr.ru"];

Promise.all(
    urls.map((url) => parseUrl(url))
).then((body) => {
    console.log(`Response arrived: ${body}`);
}).catch((err) => {
    console.log(`Error occured: ${err}`);
});
