详解Nodejs中自动化浏览器操作神器Puppeteer的使用

npm install puppeteer

const puppeteer = require('puppeteer');

async function run() {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await page.screenshot({path: 'example.png'});
  await browser.close();
}

run();

const puppeteer = require('puppeteer');

async function login() {
  const browser = await puppeteer.launch({headless: false});
  const page = await browser.newPage();
  await page.goto('https://example.com/login');

  await page.type('#username', 'yourUsername');
  await page.type('#password', 'yourPassword');
  await page.click('#submit');

  await page.waitForNavigation();
  console.log('Logged in!');
  await browser.close();
}

login();

const puppeteer = require('puppeteer');

async function interceptNetwork() {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();

  await page.setRequestInterception(true);
  page.on('request', request => {
    if (request.url().endsWith('.png') || request.url().endsWith('.jpg'))
      request.abort();
    else
      request.continue();
  });

  await page.goto('https://example.com');
  await browser.close();
}

interceptNetwork();
