# Puppeteer

#### 什么是Puppeteer？

[**Puppeteer**](https://developer.chrome.com/docs/puppeteer)是一个 JavaScript 函式库，它提供进阶 API 来透过 DevTools 协定或 WebDriver BiDi 控制 Chrome 或 Firefox。 Puppeteer 预设在无头（无可见 UI）中运行，但可以配置为在可见（「有头」）浏览器中运行。

const puppeteer = require('puppeteer');
(async () => {
  const browser = await puppeteer.launch({
    headless: false,
    args: ['--proxy-server=t.pr.thordata.net:9999]  
});
  const page = await browser.newPage();
    await page.authenticate({
        username: 'td-customer-USERNAME',
        password: 'PASSWORD'
    });
    await page.goto('https://ipinfo.thordata.com');
    await page.screenshot({path: 'example.png'});
    await browser.close();
})();
