在我的settings.py下

SPLASH_URL = 'http://127.0.0.1:8050'
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'

我的蜘蛛源代码

# -*- coding: utf-8 -*-
import scrapy
from scrapy.spiders import CrawlSpider
from scrapy_splash import SplashRequest

class SampleSpider(CrawlSpider):
  name = 'sample'
  allowed_domains = ['sample.com']

  def start_requests(self):
    urls = [
      'https://www.sample.com/view-all-clothing/bottoms/leggings'
    ]

    for url in urls:
      yield SplashRequest(url=url, callback=self.parse)

  def parse(self,response):
    for item in response.css("li.product-compact"):
      yield {
        'category_link': response.request.url,
        'title': item.css("a.pdp-link::text").extract()
      }

  pass

我已经完成了所有这些我知道没问题的设置，但我想不出我哪里做错了。

请让我知道，因为我还是 python、scrapy 和 splash JS 渲染服务的新手

它应该在settings.py 中设置：

SPLASH_URL = 'http://0.0.0.0:8050'

并且 docker 容器应该是监听服务器的网卡。

0.0.0.0:8050->8050/tcp
