使用 Puppeteer，您将如何从网站上抓取标题和图像，并将它们放在同一个 object 中，以便图像与标题相关？

Question

I am able to get the image src and the title in seperate variables with this code,

  let theOfficeUrl =
    "https://www.cardboardconnection.com/funko-pop-the-office-vinyl-figures";

  let browser = await puppeteer.launch({
    headless: true,
    defaultViewport: null,
  });
  let page = await browser.newPage();

  await page.goto(theOfficeUrl), { waitUntil: "networkidle2" };

  let data = await page.evaluate(() => {
    var image = Array.from(
      document.querySelectorAll("div.post_anchor_divs.gallery img")
    ).map((image) => image.src);

    // gives us an array off all h3 titles on page
    var title = Array.from(document.querySelectorAll("h3")).map(
      (title) => title.innerText
    );
    let forDeletion = ["", "Leave a Comment:"];
    title = title.filter((item) => !forDeletion.includes(item));

    return {
      image,
      title,
    };
  });
  console.log("Running Scraper...");
  console.log({ data });
  console.log("======================");
})();

which yields results like this

data: {
   image: [Array of image srcs],
   title: [Array of title text]
 }
}

But I need them to be an array of objects that have the corresponding titles and image srcs like this

{
data: [
   {
   item: {
      title: "title from website",
      image: "image src from website"
   }
item: {
      title: "title from website",
      image: "image src from website"
   }
item: {
      title: "title from website",
      image: "image src from website"
   }
....so on
 ]
}

Problem i am running into is the website does not have each image and title in a seperate div, they are all in one container div with h3 tags holding title with no class names, and img being in p tags and sometimes h3 tags as well. Website i am trying to scrape

https://www.cardboardconnection.com/funko-pop-yu-gi-oh-vinyl-figures

Trying to scrape the Funko Pop Yu-Gi-Oh. Figures Gallery portion where it has the name of the funko pop and the image beneath it.

Any pointers on this?

Answer 1

Once you have got the individual arrays in the data object, you can create the desired array like so:

data = {
    image: ["image1 src", "image2 src", "image3 src", "image4 src"],
    title: ["title1", "title2", "title3", "title4"]
}

data_new = [];
for (i=0;i<data.image.length;i++) {
  data_new.push({'image':data.image[i], 'title': data.title[i]})
}

This should give you:

data_new = [
    {
        "image": "image1 src",
        "title": "title1"
    },
    {
        "image": "image2 src",
        "title": "title2"
    },
    {
        "image": "image3 src",
        "title": "title3"
    },
    {
        "image": "image4 src",
        "title": "title4"
    }
]

You can try something like this (as images ara lazy-loaded, data-src attribute is more appropriate here):

import puppeteer from 'puppeteer';

const browser = await puppeteer.launch();

try {
  const [page] = await browser.pages();

  await page.goto('https://www.cardboardconnection.com/funko-pop-the-office-vinyl-figures');

  const data = await page.evaluate(() => {
    const titles = Array.from(
      document.querySelectorAll("div.post_anchor_divs.gallery h3")
    ).filter(title => title.innerText !== '');

    return titles.map(title => ({
      title: title.innerText,
      image: title.nextSibling.nextSibling.querySelector('img').dataset.src,
    }));
  });
  console.log(data);
} catch(err) { console.error(err); } finally { await browser.close(); }
