docker 部署 puppeteer

官方提供的Dockerfile1️⃣

FROM node:12-slim

# Install latest chrome dev package and fonts to support major charsets (Chinese, Japanese, Arabic, Hebrew, Thai and a few others)
# Note: this installs the necessary libs to make the bundled version of Chromium that Puppeteer
# installs, work.

# If running Docker >= 1.13.0 use docker run's --init arg to reap zombie processes, otherwise
# uncomment the following lines to have `dumb-init` as PID 1

# RUN chmod +x /usr/local/bin/dumb-init

# Uncomment to skip the chromium download when installing puppeteer. If you do,
# you'll need to launch puppeteer with:
#     browser.launch({executablePath: 'google-chrome-stable'})
# ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD true

# Install puppeteer so it's available in the container.
RUN npm init -y &&  \
    npm i puppeteer \
    # Add user so we don't need --no-sandbox.
    # same layer as npm install to keep re-chowned files from using up several hundred MBs more space

构建

# 需要挂代理，我build了一个，并上传到了阿里云，可以直接使用：registry.cn-hangzhou.aliyuncs.com/cuiw/puppeteer-chrome-linux:20210916
cd puppeteer
docker build -t puppeteer-chrome-linux .

puppeteer/server.js

获取ks的视频链接，接收一个url参数（在ks中分享出来的链接）

const http = require("http");
const puppeteer = require('puppeteer');
const server = http.createServer(function (req, res) {
  const urlObj = new URL('http://localhost:3000' + req.url)
  // console.log(urlObj)
    let url = urlObj.searchParams.get('url');
    if (null !== url && url.length > 0) {
      if (urlObj.pathname === '/ks/video') {
        (async () => {
        const browser = await puppeteer.launch({
          args:['--no-sandbox', '--disable-setuid-sandbox'],
        });
        const page = await browser.newPage();
        // 设置浏览器信息
        await page.emulate(puppeteer.devices['iPhone X']);
        await page.goto(url);
        let video = await page.$eval('#video-player', el => el.src);
        console.log(video)

        res.writeHead(200, {"Content-Type": "application/json"});
        let json = JSON.stringify({'url': video });
        res.end(json);

        await browser.close();
      })();
    }
  }else res.end();

});
