linux安装 略;
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
var route = process.argv[2];
var pageName = process.argv[3];
await page.goto(route, {waitUntil: 'networkidle2'});
await page.pdf({ path: pageName, scale: 1, landscape: true, printBackground: true, format: "A4", preferCSSPageSize: true, displayHeaderFooter: false, margin: { left: "10mm", right:"9.5mm",top:"10mm",bottom:"9.5mm"}})
await browser.close();
})();
自定义浏览器和puppeteer路径
报错:

引用浏览器设置 args: ['--no-sandbox', '--disable-setuid-sandbox']
const puppeteer = require('/root/node_modules/puppeteer');
const path = require('path');
(async () => {
// const browser = await puppeteer.launch();
const browser = await puppeteer.launch({
// 这里注意路径指向可执行的浏览器。
// 各平台路径可以在 node_modules/puppeteer-core/lib/BrowserFetcher.js 中找到
// Mac 为 '下载文件解压路径/Chromium.app/Contents/MacOS/Chromium'
// Linux 为 '下载文件解压路径/chrome'
// Windows 为 '下载文件解压路径/chrome.exe'
args: ['--no-sandbox', '--disable-setuid-sandbox'],
executablePath: path.resolve('/root/node_modules/puppeteer/.local-chromium/linux-641577/chrome-linux/chrome')
});
const page = await browser.newPage();
var route = process.argv[2];
var pageName = process.argv[3];
await page.goto(route, {waitUntil: 'networkidle2'});
await page.pdf({ path: pageName, scale: 1, landscape: true, printBackground: true, format: "A4", preferCSSPageSize: true, displayHeaderFooter: false, margin: { left: "10mm", right:"9.5mm",top:"10mm",bottom:"9.5mm"}})
await browser.close();
})();
完成。
