在Puppeter实例中运行循环

刚开始使用Puppeter,我可以启动浏览器,转到url,运行一系列操作,然后关闭浏览器。我想看看是否可以打开浏览器并在同一会话中循环一组操作。

我有一个JSON对象,其中包含我想访问的URL,所以我想循环访问它

// teams.js
module.exports = {
  premier_league: [
    { team_name: "Team 1", url: "https://url-of-site/team_1"},
    { team_name: "Team 2", url: "https://url-of-site/team_2"}
  ]
}

我的《木偶师》剧本如下

// index.js
const TEAM = require('./teams');
const puppeteer = require('puppeteer');

(async () => {
  // Initialise Browser
  const browser = await puppeteer.launch({headless: false});
  const page = await browser.newPage();
  await page.setViewport({
    width: 1280,
    height: 800
  });
  await page.goto('login page');

  await page.click('login_box');
  await page.keyboard.type('username');

  await page.click('login_password');
  await page.keyboard.type('password');

  await page.click('login_button');
  await page.waitForNavigation();

  // Go To Team URL
  await page.goto('Team URL')

  await browser.close();
})();

所以为了循环我的JSON对象,我可以使用

Object.keys(TEAM['premier_league']).forEach(function(key) {

  // Output url of each team
  console.log(TEAM['premier_league'][key]['url'])

});

如果我用循环包装我的go-to url,那么 page 不再可访问

// index.js
const TEAM = require('./teams');
const puppeteer = require('puppeteer');

(async () => {
  // Initialise Browser
  const browser = await puppeteer.launch({headless: false});
  const page = await browser.newPage();
  await page.setViewport({
    width: 1280,
    height: 800
  });
  await page.goto('login page');

  await page.click('login_box');
  await page.keyboard.type('username');

  await page.click('login_password');
  await page.keyboard.type('password');

  await page.click('login_button');
  await page.waitForNavigation();

  Object.keys(TEAM['premier_league']).forEach(function(key) {

    // Go To Team URL
    await page.goto(TEAM['premier_league'][key]['url'])

  });

  await browser.close();
})();

实际误差为

await page.goto(TEAM[args][key]['url'])
    ^^^^
