它显示

works=False

。我不知道这为什么不起作用

任何帮助都将不胜感激。谢谢

首先显示

response.body

以查看您得到的信息-可能您会看到一些有关机器人程序、验证码或其他有用信息的警告。您没有最重要的标题：

USER-AGENT

。这是服务器检查以跳过bot的第一个头。@furas用户代理也一样。我对问题进行了编辑，将其包括在内。我在测试中确实显示了response.body。因为head中包含的脚本太大，所以未包含在此处。响应主体是这样的：

脚本就在这里：因为您已经使用Selenium进行了测试，并且显然包含了正确的标题，所以我不确定是否可以提供更多的信息来诊断Scrapy，但尝试一下可能会有所帮助。它打开一个浏览器窗口并访问它刮取的每个URL，这意味着它不模仿浏览器，而是使用您的浏览器（包括扩展、cookie等）。如果它能工作，也许这就足够了，或者至少可以帮助你缩小这个问题。在

中，似乎是JavaScript加载了所有东西，但

Scrapy

不能运行JavaScript-你可能需要

Selenium

（）或

Splash

（）才能在真正的web浏览器中运行
