Scrapy bypassing start_urls

Question

When running this spider, scrapy tells me that the pages being scraped are 'http://192.168.59.103:8050/render.html' (the splash render endpoint defined in the start_requests "meta" parameter). Of course this is the url that I want to pass start_urls to , not the ones I want to scrape. I'm guessing the issue is with how I'm passing urls from start_urls to start_requests to parse, but I can't pinpoint the exact problem.

also here's my settings file

thanks in advance.

import scrapy
from scrapy.http import Request
from scrapy.selector import Selector
from scrapy.spiders import CrawlSpider, Rule

                    'endpoint': 'render.html',
                    'args': {'wait': 1}
                }
            })

    def parse(self, response):
        ResultsDict = Check_Item()
        Select = Selector(response).xpath

        ResultsDict['title'] = Select(".//*[@class='h1']/text()|.//*[@id='btAsinTitle']/text()").extract()
        ResultsDict['application_url'] = response.url
        return ResultsDict

I suggest that you upgrade to the latest scrapy-splash plugin (what used to be called scrapyjs )

There's a handy scrapy_splash.SplashRequest utility that will "fix" the URL to the original remote host and not the Splash endpoint.

This is an example spider similar to yours:

import scrapy
from scrapy_splash import SplashRequest


class CheckSpider(scrapy.Spider):
    name = "scrapy-splash-example"
    handle_httpstatus_list = [404,429,503]

    start_urls = [
        "http://rads.stackoverflow.com/amzn/click/B00PRH5UJW",
        "http://rads.stackoverflow.com/amzn/click/B00KFITEV8",
        "http://rads.stackoverflow.com/amzn/click/B00J0T73XO",
        "http://rads.stackoverflow.com/amzn/click/B00O65Z0RS",
        "http://rads.stackoverflow.com/amzn/click/B00N3DDDRI"
    ]

    def start_requests(self):
        for url in self.start_urls:
            yield SplashRequest(url,
                                callback=self.parse,
                                args={
                                    'wait': 1,
                                })

    def parse(self, response):
        self.logger.debug("Response: status=%d; url=%s" % (response.status, response.url))
