'Cookies / data handling redirect causes wrong scraping website
I have a problem with a very simple custom spider, but I can't figure it out. Scrapy is redirected to the consent.yahoo page when trying to scrape a page on yahoo finance.
The spider looks like this:
import scrapy
class CompanyDetailsSpider(scrapy.Spider):
name = 'company_details'
allowed_domains = ['finance.yahoo.com']
start_urls = ['https://finance.yahoo.com/screener/predefined/ms_technology']
def parse(self, response):
company_names_list = response.xpath(
'//*[@id="scr-res-table"]/div[1]/table/tbody/tr/td[2]/text()').extract()
company_price_list = response.xpath(
'//*[@id="scr-res-table"]/div[1]/table/tbody/tr/td[3]/span/text()').extract()
count = len(company_names_list)
for i in range(0, count):
print(company_names_list[i], company_price_list[i])
This code was taken from a course on scrapy, where it did work. The problem is when I try to run it. It shows me:
2022-02-01 15:29:08 [scrapy.downloadermiddlewares.redirect] DEBUG: Redirecting (307) to <GET https://guce.yahoo.com/consent?brandType=nonEu&gcrumb=TEYoGM4&done=https%3A%2F%2Ffinance.yahoo.com%2Fscreener%2Fpredefined%2Fms_technology> from <GET https://finance.yahoo.com/screener/predefined/ms_technology>

And when I view the response when I simply run the page in a scrapy shell, it shows: that is redirected to a (cookies?) request page.
I can't find a solution to this anywhere as I can't find anyone reporting the same issue. However, other cookie-related issues say that cookies should be enabled, which I did. And the robot.txt is turned to false. My settings look like this:
BOT_NAME = 'SimpleSpider'

I hope anyone could help with this!
