const puppeteer = require('puppeteer');
const url = 'https://segmentfault.com';

(async() => {
const browser = await puppeteer.launch({
headless: true,
args: ["--no-sandbox", "--single-process"],
});
const page = await browser.newPage();
await page.setViewport({ width: 1920, height: 1080 });
// ‘networkidle2’ means that there are no more than 2 active requests open.
// This is a good setting because for some websites (e.g. websites using websockets) there will always be connections open
await page.goto(url, {
waitUntil: 'networkidle2',
timeout: 1000 * 60 * 5, // 毫秒 超时参数需要加上,有时候网络不好,会导致等着
});
await page.screenshot({path: './data/website.png', type: 'png'});
page.close();
browser.close();
})();
