将回调转换为异步的节点导致暂停执行

Question

这里是初级 JS。我计划从多个站点收集 cookie，因此我想将以下内容转换为 Node.js 辅助函数。

const chrome = require('chrome-cookies-secure');
const puppeteer = require('puppeteer');

const url = 'https://www.*.com';
const getCookies = (callback) => {
    chrome.getCookies(url, 'puppeteer', function(err, cookies) {
        if (err) {
            console.log(err, 'error');
            return
        }
        console.log(cookies, 'cookies');
        callback(cookies);
    }, 'Profile 6') // e.g. 'Profile 2'
}

// find profiles at ~/Library/Application Support/Google/Chrome

getCookies(async (cookies) => {
    const browser = await puppeteer.launch({
        headless: false
    });
    const page = await browser.newPage();

    await page.setCookie(...cookies);
    await page.goto(url);
    await page.waitFor(5000);
    browser.close()
});

上面的代码使用来自 Chrome 的 cookie 启动 puppeteer。

我在下面尝试将其作为一个函数，以便我可以轻松传递下面的任何 url。

helper.js

const chrome = require('chrome-cookies-secure');
module.exports.get_cookies = async (url) => {
    chrome.getCookies(url, 'puppeteer', function(err, cookies) {
        if (err) {
            console.log(err, 'error');
            return
        }
        console.log(cookies, 'cookies');
        return Promise.resolve(cookies);
    }, 'Profile 1') // e.g. 'Profile 2'
}

*.js

run = async () => {
    var helper = require('./helper.js')
    const browser = await puppeteer.launch({
        headless: false
    });
    const page = await browser.newPage();
    const url = 'https://www.*.com/';
    var cookies = await helper.get_cookies(url);
    console.log('got cookies');
    await page.setCookie(...cookies);
    await page.goto(url);
    await page.waitFor(5000);
    browser.close()
}

run()

问题是在控制台记录 cookie 后执行暂停。我不确定如何解决此问题。当我 ^C 时，js 并没有告诉我它在执行什么，它只是中断了。

更新

感谢Molda，我能够得到返回的cookies。现在正在尝试处理 Promise 拒绝。

非常感谢 LJHarb 和 Molda

function getCookies(url) {
    return new Promise((resolve, reject) => {
      chrome.getCookies(url, 'puppeteer', function (err, cookies) {
        if (err) { reject(err); }
        else { resolve(cookies); }
      }, chrome_profile);
    });
  }
