I would like to scrape an arbitrary offer from aliexpress. Im trying to use scrapy and selenium. The issue I face is that when I use chrome and do right click > inspect on a element I see the real HTML but when I do right click > view source I see something different - a HTML CSS and JS mess all around.
As far as I understand the content is pulled asynchronously? I guess this is the reason why I cant find the element I am looking for on the page.
I was trying to use selenium to load the page first and then get the content I want but failed. I'm trying to scroll down to get to reviews section and get its content
Is this some advanced anti-bot solution that they have or maybe my approach is wrong?
The code that I currently have:
import scrapy
from selenium import webdriver
import logging
import time
logging.getLogger('scrapy').setLevel(logging.WARNING)
class MySpider(scrapy.Spider):
name = 'myspider'
start_urls = ['https://pl.aliexpress.com/item/32998115046.html']
def __init__(self):
self.driver = webdriver.Chrome()
def parse(self, response):
self.driver.get(response.url)
scroll_retries = 20
data = ''
while scroll_retries > 0:
try:
data = self.driver.find_element_by_class_name('feedback-list-wrap')
scroll_retries = 0
except:
self.scroll_down(500)
scroll_retries -= 1
print("----------")
print(data)
print("----------")
self.driver.close()
def scroll_down(self, pixels):
self.driver.execute_script("window.scrollTo(0, {});".format(pixels))
time.sleep(2)
By watching requests in network tab in inspect tool of browser you will find out comments are comming from here so you can crawl this page instead.
