I got a subscription for splash on scrapinghub and I want to use this from a script that is running on my local machine. The instructions I have found so far are:

  1. Edit the settings file:

I got this one from my scraping hub account SPLASH_URL = 'http://xx.x0-splash.scrapinghub.com'

DOWNLOADER_MIDDLEWARES = { 'scrapy_splash.SplashCookiesMiddleware': 723, 'scrapy_splash.SplashMiddleware': 725, 'scrapy.downloadermiddlewares.httpcompression.HttpCompressionMiddleware': 810, }
SPIDER_MIDDLEWARES = { 'scrapy_splash.SplashDeduplicateArgsMiddleware': 100, }
DUPEFILTER_CLASS = 'scrapy_splash.SplashAwareDupeFilter'
HTTPCACHE_STORAGE = 'scrapy_splash.SplashAwareFSCacheStorage'
From that I have one question, when I try to open the splash server on the browser it asks me for a username, I don't see where to set this on scrapy.

  1. the spider file:
    import scrapy import json from scrapy import Request from scrapy_splash import SplashRequest import scrapy_splash
    class ListSpider(scrapy.Spider):
name = 'list'
 allowed_domains = ['https://medium.com/']
 start_urls = ['https://medium.com/']

 def parse(self, response):
     print (response.body)
     with open('data/cookies_file.json') as f:
         cookies_data = json.loads(f.read())[0]
     #print (cookies_data)
     url = 'https://medium.com/' 
     #cookies=cookies_data,
     yield Request(url,  callback=self.afterlogin,meta={'splash': {'args': {'html': 1, 'png': 1,}}})

 def afterlogin(self,response):
     with open(data_dir + 'after_login_page.html','w') as f:
         f.write(str(response.body))

I'm not getting errors but I'm not sure if splash is working either, also besides the server ip, scraping provides a password which I don't know where to use for this script.
After using splashrequest and adding the API key, This is the traceback of I'm getting, the content of the sites is still not loading.

如果您查看他们的示例文件，就会发现他们已经展示了如何使用它
https://github.com/scrapy-plugins/scrapy-splash/blob/e40ca4f3b367ab463273bee1357d3edfe0601f0d/example/scrashtest/spiders/quotes.py


# -*- coding: utf-8 -*-

import scrapy
from scrapy.linkextractors import LinkExtractor

from scrapy_splash import SplashRequest

class QuotesSpider(scrapy.Spider):
    name = "quotes"
    allowed_domains = ["toscrape.com"]
    start_urls = ['http://quotes.toscrape.com/']

    # http_user = 'splash-user'
    # http_pass = 'splash-password'

    def parse(self, response):
        ...

此外，您需要生成SplashRequest而不是Request，您实际上在代码中根本没有使用Splash

yield Request(url,  callback=self.afterlogin,meta={'splash': {'args': {'html': 1, 'png': 1,}}})

应该是

yield SplashRequest(url,  callback=self.afterlogin,meta={'splash': {'args': {'html': 1, 'png': 1,}}})
