puppeteer中的页面cookie无法用于保持登录状态

我想在，而无需重新扫描二维码我知道我必须保存cookie并设置以备下次使用扫描二维码并登录到我的帐户后，我在Google chrome开发工具，应用程序选项卡和Cookie部分中看到了cookie，但是page.cookie为空并返回[]我尝试使用示例代码将cookie存储在文件中。在运行代码mycookie.json并创建[]后，运行代码。

怎么办？

const puppeteer = require('puppeteer');
const jsonfile = require('jsonfile');
(async () => {
    const browser = await puppeteer.launch({
        headless: false,
        args: ['--start-maximized']
    });
    const page = await browser.newPage();
    await page.setUserAgent('Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.132 Safari/537.36');
    await page.setViewport({ width: 1280, height: 800 });
    await page.goto('/', {waitUntil: 'networkidle0'});
    await page.setViewport({
        width: 1440,
        height: 900
    });
    await page.waitFor(10000);//wait for scan qr
    console.log(await page.cookies());

    // Save Session Cookies
    var cookiesFilePath = 'mycookie.json';
    const cookiesObject = await page.cookies();
    // Write cookies to temp file to be used in other profile pages
    jsonfile.writeFile(cookiesFilePath, cookiesObject, { spaces: 2 },
     function(err) { 
      if (err) {
      console.log('The file could not be written.', err)
      }
      console.log('Session has been successfully saved')
    })
})();

回答如下：

您应该使用userDataDir如果您使用它，则不会丢失浏览器数据。即使您得到的cookie数据也无济于事，因为Web WhatsApp也使用local-storage。
