Question

在带窗口的镶边中为fb chatbot运行此硒脚本时，运行正常。 在无头模式下，即使使用python虚拟显示，也会被检测到并被阻止。

我想使用pyvirtualdisplay在无头模式下运行脚本，同时避免被检测，以便我可以将远程任务作为日常计划任务执行。

这是针对数字海洋中的 ubuntu 18.04液滴。

respondToNewMessages()

browser.close()

预期-无头w虚拟显示将反映在窗口镶边中运行。

实际-窗口运行正常，Facebook侦测到无头并阻止了它。

Answer 1

pyvirtualdisplay和浏览器的无头模式的功能相同，因此，如果使用pyvirtualdisplay，则不应设置chrome_options.add_argument('headless')。

安装xvfb（sudo apt-get install xvfb）并将其设置为后端：

display = Display(backend="xvfb", visible=0, size=(800, 800))

当硒无头运行时，facebook检测到浏览器自动化
