【问题描述】:
我正在尝试在 Python 中使用 PhantomJS(在 Windows 中)和 Selenium 来进行一些网页抓取。
我已经从网站下载了最新的 PhantomJS 版本,然后解压缩。之后我试过了
from selenium import webdriver
browser = webdriver.PhantomJS()
反应是
WebDriverException: 'phantomjs' executable needs to be in PATH.
然后我尝试添加路径,比如
browser = webdriver.PhantomJS('path_to/phantomjs.exe')
我还尝试在路径前添加一个“r”。响应是 HTML 中的一个 exxeption:
WebDriverException: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

我已将此代码打开到 Chrome 会话中,它会打开我公司的防火墙页面。消息是“系统无法与外部服务器(127.0.0.1)通信。”。我可以使用 Chrome 或 Firefox 驱动程序进行 webscrape,但我在使用 PhantomJS 时遇到了这个问题。
你能帮帮我吗?

我还发现使用的 URL 是 POST 127.0.0.1/wd/hub/session。有没有办法改变这个?这显然是公司防火墙的问题。
