你好，我试图使抓取机器人的网站，使用JavaScript.我有大约20从该网站的网址，并希望扩大到houncers，我需要的网址被刮得很频繁，所以我尝试使用lua脚本做“动态”等待时间.当我使用默认的webkit引擎，该网站的html输出只是文本说，该网站不支持此浏览器，这就是为什么我使用chromium引擎。没有lua脚本，scraping只提供chromium引擎的输出项，但它确实有效。在我尝试使用lua之后，我使用chromium引擎得到了错误，使用webkit它执行时没有错误，但没有给予任何输出项。这是我使用lua的开始请求：

def start_requests(self):
        lua_script = """
        function main(splash, args)
            assert(splash:go(args.url))

            while not splash:select('div.o-matchRow')
                splash:wait(1)
                print('waiting...')
            end
            return {html=splash:html()}
        end    
        """

        for url in self.start_urls:
            yield SplashRequest(
                url=url,
                callback=self.parse,
                endpoint='execute',
                args={'engine': 'chromium', 'lua_source': lua_script}
            )

字符串
这是一些简单的东西，我想测试出来。有人知道什么是处理lua和 chrome 引擎，或者我怎么能使用webkit时，网站不支持它？（顺便说一句，对不起我的英语，我不是一个母语）这些是与 chrome 引擎的错误：
