为什么 pyppeteer 需要这么长时间才能在 AWS Lambda 上加载单个网页

Question

I am currently trying to crawl MVN Repository using puppeteer on AWS Lambda. However, my test function would run for 15 minutes and proceed to fail after that (See below). It seems like the browser is opened but it doesn't crawl.

Here is my current code:

import json
import asyncio
from pyppeteer import launch
import pyppeteer
import zipfile
import boto3
import time
# import pandas as pd
import os
import logging
import subprocess
from pyppeteer.launcher import Launcher

logger = logging.getLogger()
logger.setLevel(logging.INFO)

pyppeteer.DEBUG = True

async def main(name, url):
    browser = await launch(headless=True, args=["--no-sandbox"], executablePath="/opt/python/headless-chromium")
    page = await browser.newPage()
    await page.setUserAgent('Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.125 Safari/537.36')
    await page.goto(url)


def lambda_handler(event, context):
    asyncio.get_event_loop().run_until_complete(main('lol','https://mvnrepository.com/artifact/com.adobe.xmp/xmpcore'))
    return {
        'statusCode': 200,
        'body': json.dumps('Hello from Lambda!')
    }

The layers for this are:

• A zipped pyppeteer of version 0.2.2
• A headless chrome version of v1.0.0-55 stable release
• A Python version of 3.7

The following is the output after the function has timed out:

}

Apart from the method I tried earlier, I also followed the following tutorials but to no avail:

• https://medium.com/limehome-engineering/running-pyppeteer-on-aws-lambda-with-serverless-62313b3fe3e2
• https://github.com/pyppeteer/pyppeteer/issues/108
• Pyppeteer: Browser closed unexpectedly in AWS Lambda

PS I am able to run the above script with no issues on my localhost

Answer 1

I built a similar configuration but using pyppeteer 1.0.2. When I tried to generate a PDF file from the URL you mentioned (mvnrepository), I got an ugly captcha issue: screen . Have you tried crawling other websites? This could be the problem.

Please let me know if you found a workaround.
