Недавно я учусь использовать Scrapy с spla sh для сканирования динамических c сайтов.
Вот содержимое моего паука:
# -*- coding: utf-8 -*-
import scrapy
from scrapy_splash import SplashRequest
class InfoSpider(scrapy.Spider):
name = 'info'
url = 'https://hackerone.com/kubernetes'
def start_requests(self):
yield SplashRequest(
self.url,
callback=self.parse,
endpoint='render.html',
args={
'wait': 15
})
def parse(self, response):
result = response.css('strong span').getall()
self.log(result)
if result:
self.log("FOUND!")
else:
self.log("NOT FOUND!")
Однако, ответ, возвращаемый spla sh, по-прежнему не совпадает с ответом, который я проверяю в браузере.
Настройки spla sh верны, так как я проверил его на localhost: 8050. Вот содержимое в моем setting.py

Надеюсь не знаю, что не так с кодом. Элементы не отображаются в окончательном коде html, полученном spla sh. Ваши советы будут высоко оценены.
