Issue
I need to scrape this site.
Is made in React so it looks. Then I tried to extract the data with scrapy-splash. I need for example the "a" element with class shelf-product-name
. But the response is an empty array. I used the wait
argument in about 5 seconds.
But I only get an empty array.
def start_requests(self):
yield SplashRequest(
url='https://www.jumbo.cl/lacteos-y-bebidas-vegetales/leches-blancas?page=6',
callback=self.parse,
args={'wait':5}
)
def parse(self,response):
print(response.css("a.shelf-product-name"))
Solution
Actually there is no need to use Scrapy Splash because all required data stored inside <script>
tag of raw html response as json formatted data:
import scrapy
from scrapy.crawler import CrawlerProcess
import json
class JumboCLSpider(scrapy.Spider):
name = "JumboCl"
start_urls = ["https://www.jumbo.cl/lacteos-y-bebidas-vegetales/leches-blancas?page=6"]
def parse(self,response):
script = [script for script in response.css("script::text") if "window.__renderData" in script.extract()]
if script:
script = script[0]
data = script.extract().split("window.__renderData = ")[-1]
json_data = json.loads(data[:-1])
for plp in json_data["plp"]["plp_products"]:
for product in plp["data"]:
#yield {"productName":product["productName"]} # data from css: a.shelf-product-name
yield product
if __name__ == "__main__":
c = CrawlerProcess({'USER_AGENT':'Mozilla/5.0'})
c.crawl(JumboCLSpider)
c.start()
