介紹

接下來我們使用 puppeteer的分析功能把抓到的 資料透過 evaluate 取到 outerHTML，因為也不想一直在網路上測試所以會把資料存成靜態檔案

        var data = await page.content()
        fs.writeFile(`page${i}.html`, data, (err) => console.log(err));

Puppeteer就使用 local file的功能搭配 evaluate 使用，local mode 要記得使用 schema為 file:///

import * as puppeteer from 'puppeteer'

(async function go() {

  const browser = await puppeteer.launch({
    headless: false,
    args: ['--start-maximized'],
    //userDataDir: "./userData/"
  });
  const page = await browser.newPage();

  await page.setUserAgent(`Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36`)
  //console.log('test use agent')
  // await watchDog;
  let currentScreen = await page.evaluate(() => {
    return {
      width: window.screen.availWidth,
      height: window.screen.availHeight,
    };
  });
  await page.setViewport(currentScreen);
  try {
    await page.goto('file:///Users/user/Sites/case/puppeteerProject/getOpenData/page1.html')

    let handle = await page.$$(".line");

    handle.forEach(async (v) => {
      let temp = await page.evaluate((data: HTMLElement) => {
        // console.log(data)
        return data.outerHTML;
      }, v)
      console.log(temp)

    })


  } catch (err) {
    console.log('err')
   
  }
})()
