Python：selenium.webdriver问题(服务器上没有X)

我拼凑了以下脚本,以在远程Asterisk / Vicidial服务器上生成每日报告.该脚本从报告中获取源代码,执行某种格式设置,将结果保存为文本文件,然后通过smtp发送给我的老板以供审核.我目前正在本地的cron作业上运行脚本,并且脚本运行良好,但是我希望能够在VPS上运行该脚本；问题是,该脚本会弹出Firefox窗口,并且VPS没有X或任何类型的GUI,因此Firefox无法打开,并且无法检索数据.

需要澄清的是,我已经安装了Firefox和所有必需的模块,并且VPS本质上与我的本地计算机(bar X和GUI(Debian Lenny))相同.

如果有人可以提供有关如何修改此脚本的任何帮助,以使其在没有X / GUI的情况下工作,将不胜感激！

谢谢,托比.

解决方法:

Corey Goldberg explains如何使用pyvirtualdisplay执行此操作.

但是,您需要能够安装pyvirtualdisplay,xvfb和xserver-xephyr.

import contextlib
import selenium.webdriver as webdriver
display = pyvirtualdisplay.Display(visible = False, size = (800, 600))
display.start()
with contextlib.closing(webdriver.Firefox()) as driver:    
    driver.get('http://www.google.com')
    print driver.title
    # Google
display.stop()

在Ubuntu / Debian上,可以使用

sudo apt-get install python-setuptools
sudo apt-get install xvfb
sudo apt-get install xserver-xephyr
sudo easy_install pyvirtualdisplay
