Question

但是我一直在外壳中遇到这个问题。

 2018-09-13 14:50:36 [scrapy.extensions.logstats] INFO: Crawled 0 pages (at 0 pages/min), scraped 0 items (at 0 items/min)

 2018-09-13 14:52:00 [scrapy.spidermiddlewares.httperror] INFO: Ignoring response <502 http://quotes.toscrape.com/js/>: HTTP status code is not handled or not allowed

这是我的代码：

import scrapy
from scrapy_splash import SplashRequest
class MySpider(scrapy.Spider):
    name = "jsscraper"

    start_urls = ["http://quotes.toscrape.com/js/"]

    def start_requests(self):
        for url in self.start_urls:
            yield SplashRequest(url=url, callback=self.parse, endpoint='render.html')

    def parse(self, response):
        for quote in response.css("div.quote"):
        scraped_info={
         'authorname':quote.css('small.author::text').extract_first(), 
         'quote':quote.css('span.text::text').extract_first(),}
          yield scraped_info

我已经安装了scrapy-splash，并且还放置了这些命令在settings.py中。另外我的启动服务器正在运行 http://localhost:8050/。

另外，当我尝试在启动服务器上呈现任何url时，又出现了另一个错误：

HTTP错误400（错误请求）类型：ScriptError-> LUA_ERROR错误   在执行Lua脚本时发生了

Lua错误：[字符串“ function main（splash，args）...”]：2：network3

我正在使用：

初始版本：3.2
卢阿5.2

尝试使用Scrapy和Splash擦除JS页面时出错
