我正在尝试抓取一个使用 scrapy-splash 插件启用了 javascript 的网站。
我已经使用 docker 安装了 splash 和这些命令我使用的是Ubuntu 16.04
$ sudo docker pull scrapinghub/splash
$ sudo docker run -p 8050:8050 scrapinghub/splash
我有正在运行的splash docker就像一切看起来都很好但是
处理scrapy错误时，splash会抛出此错误

process 1: D-Bus library appears to be incorrectly set up; failed to read machine uuid: UUID file '/etc/machine-id' should contain a hex string of length 32, not length 0, with no other text
**See the manual page for dbus-uuidgen to correct this issue.
qt.network.ssl: QSslSocket: cannot resolve SSLv2_client_method
qt.network.ssl: QSslSocket: cannot resolve SSLv2_server_method**
我认为这部分可能是问题所在
qt.network.ssl: QSslSocket: cannot resolve SSLv2_client_method
qt.network.ssl: QSslSocket: cannot resolve SSLv2_server_method
而且该网站是一个 HTTPS 网站
在剪贴画中
我在scrapy中导入了这样的scrapy- splash
from scrapy_splash import SplashRequest
我正在提出这样的要求
yield SplashRequest(link, meta={'item': item}, callback=self.parse_data)
代替
yield scrapy.Request(link, meta={'item': item}, callback=self.parse_data)
但像往常一样，飞溅没有处理请求
我在这里做错了什么？Ubuntu有什么问题吗？
