Question

我想：

访问初始化会话的页面
将会话存储在JSON对象中
访问同一页面，该页面现在应该识别现有会话

我尝试的实现如下：

import puppeteer from 'puppeteer';

const createSession = async (browser, startUrl) => {
  const page = await browser.newPage();

  await page.goto(startUrl);

  await page.waitForSelector('#submit');

  const cookies = await page.cookies();
  const url = await page.url();

  return {
    cookies,
    url
  };
};

const useSession = async (browser, session) => {
  const page = await browser.newPage();

  for (const cookie of session.cookies) {
    await page.setCookie(cookie);
  }

  await page.goto(session.url);
};

const run = async () => {
  const browser = await puppeteer.launch({
    headless: false
  });

  const session = await createSession(browser, 'http://foo.com/');

  // The session has been established
  await useSession(browser, session);
  await useSession(browser, session);
};

run();

createSession用于捕获已加载页面的Cookie。
useSession应使用现有Cookie加载页面。

但是，这不起作用 - session.url页面无法识别会话。似乎并非所有的cookie都是以这种方式捕获的。

Answer 1

page#cookies似乎会返回一些session=true,expires=0配置的Cookie。 setCookie忽略了这些值。

我通过构建覆盖expires和session属性的新Cookie数组来解决这个问题。

const cookies = await page.cookies();

const sessionFreeCookies = cookies.map((cookie) => {
  return {
    ...cookie,
    expires: Date.now() / 1000 + 10 * 60,
    session: false
  };
});

在撰写此答案时，未记录session属性。请参阅以下问题https://github.com/GoogleChrome/puppeteer/issues/980。

您可以调用内部方法page.cookies()来从所有域中获取Cookie。

Network.getAllCookies
