請告訴我 scrapy 啟動代碼有什么問題

Question

我試圖 scrapy 三星新聞室墨西哥的內容（#recent_list_box > li）數據。 但它不起作用，你能告訴我為什么嗎？

https://news.samsung.com/mx

想我帶來了 javascript 的內容，但我看不懂

版本：scrapy：2.1.0 飛濺：3.4.1

蜘蛛代碼

import scrapy
from scrapy_splash import SplashRequest
from scrapy import Request


class CrawlspiderSpider(scrapy.Spider):
    name = 'crawlspider'
    allowed_domains = ['news.samsung.com/mx']
    page = 1
    start_urls = ['https://news.samsung.com/mx']

    def start_request(self):
        for url in self.start_urls:
            yield SplashRequest(
                         url,
                         self.main_parse,
                         endpoint='render.html',
                         args = {'wait': 10}
                     )

    def parse(self, response):
        lists = response.css('#recent_list_box > li').getAll()
        for list in lists:
            yield {"list" :lists.get() }

我們已經包括了所涉及的中間件。 設置代碼

BOT_NAME = 'spider'
SPIDER_MODULES = ['spider.spiders']
NEWSPIDER_MODULE = 'spider.spiders'
LOG_FILE = 'log.txt'
AJAXCRAWL_ENABLED = True
ROBOTSTXT_OBEY = False
SPLASH_URL = 'http://127.0.0.1'
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'
SPLASH_LOG_400 = True

以下是日志文件中的剩余日志。 如果您能告訴我為什么留下下面的日志以及為什么我無法讀取我想要的數據，我將不勝感激

你必須改變

lists = response.css('#recent_list_box > li').getAll()

至

lists = response.css('#recent_list_box > li').getall()

小寫字母“a”
