How to get cookies from response of scrapy splash

it should still fix some issue You can try the following approach: - write a small Lua script that returns the html + the cookies:
lua_request = """
    function main(splash)
        splash:init_cookies(splash.args.cookies)
        assert(splash:go(splash.args.url))
        splash:wait(0.5)
        return {
            html = splash:html(),
            cookies = splash:get_cookies()
        }
    end
    """
yield SplashRequest(
    url,
    self.parse,
    endpoint='execute',
    args={'lua_source': self.lua_request}
)
def parse(self, response):
    cookies = response.data['cookies']
    headers = response.headers

Scrapy selector not working on Splash response


Tag : python , By : user186435

it fixes the issue Your spider works fine with me, with Scrapy 1.1, Splash 2.1 and no modification of the code in your question, just using settings suggested in https://github.com/scrapy-plugins/scrapy-splash
As other have mentioned, your parse function can be simplified by using response.css() and response.xpath() directly, without needing to re-build a Selector from the response.
import scrapy
from scrapy.selector import Selector
from scrapy_splash import SplashRequest

class CartierSpider(scrapy.Spider):
  name = 'cartier'
  start_urls = ['http://www.cartier.co.uk/en-gb/collections/watches/mens-watches/ballon-bleu-de-cartier/w69017z4-ballon-bleu-de-cartier-watch.html']

  def start_requests(self):
    for url in self.start_urls:
      yield SplashRequest(url, self.parse, args={'wait': 0.5})

  def parse(self, response):
    yield {
      'title': response.xpath('//title/text()').extract_first(),
      'link': response.url,
      'productID': response.xpath('//span[@itemprop="productID"]/text()').extract_first(),
      'model': response.xpath('//span[@itemprop="model"]/text()').extract_first(),
      'price': response.css('div.price-wrapper').xpath('.//span[@itemprop="price"]/text()').extract_first(),
    }

How to set cookies in Scrapy+Splash when javascript makes multiple requests?


Tag : development , By : user184975

I wish this help you Yes, there is an example in scrapy-splash README - see Session Handling section. In short, first, make sure that all settings are correct. Then use SplashRequest(url, endpoint='execute', args={'lua_source': script}) to send scrapy requests. Rendering script should be like this:
function main(splash)
    splash:init_cookies(splash.args.cookies)

    -- ... your script

    return {
        cookies = splash:get_cookies(),
        -- ... other results, e.g. html
    }
end

Scrapy: missing cookies in response

wish helps you I've created the basic scrapy project and enabled cookiemiddleware as in documentation. , After adding
USER_AGENT = 'Mozilla/5.0 (X11; Linux x86_64; rv:50.0) Gecko/20100101 Firefox/50.0'

Getting a response body with scrapy splash


Tag : python , By : redha

I think the issue was by ths following , open_in_browser() cannot detect responses from Splash as HTML responses. This is because Splash HTML response objects are subclasses of Scrapy’s TextResponse instead of HtmlResponse (for now).
You could reimplement open_in_browser() in a way that works for your use case for the time being.
