我正试图抓取一个网站，该网站启用了scrapy splash插件的javascript

而且该网站是HTTPS网站

发痒我在scrapy

from scrapy_splash import SplashRequest

我提出这样的要求

yield SplashRequest(link, meta={'item': item}, callback=self.parse_data)

而不是

yield scrapy.Request(link, meta={'item': item}, callback=self.parse_data)

但像往常一样，splash不处理这些请求

我做错了什么？Ubuntu有什么问题吗

您是否尝试在浏览器中打开Splash控制台（即，将浏览器指向安装了Splash的主机上的端口

）？另外，你能分享spider run的碎片日志吗？是的，我通过访问尝试了splash，我现在会更新这个问题。我还看到splash日志中的

qt.network.ssl:qsslslslssocket:无法解析SSLv2_client_方法

，但我能够呈现raymourflanigan.com上的页面。您的并发级别是什么？也许您的Splash实例无法处理来自Scrapy的

并发请求的负载？如果降低并发性，会有什么变化吗？或者启用Autothrottle？然后您可以使用您的Splash日志和scrapy Logstack打开Splash或scrapy Splash上的bug查看常见问题获取网关超时。另外，我会先增加飞溅的日志级别（请参阅）。你呢
