python - Python3 Selenium Webdriver在初始化期间超时

Question

以下脚本:

from selenium import webdriver
wd = webdriver.Firefox()

或者

from selenium import webdriver
wd = webdriver.Chrome()

在Windows 7计算机上几乎总是会失败，并产生以下堆栈跟踪:

Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "C:\Users\username\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 152, in __init__
keep_alive=True)
   File "C:\Users\username\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 98, in __init__

   File "C:\Users\username\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 188, in start_session
response = self.execute(Command.NEW_SESSION, parameters)
   File "C:\Users\username\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 254, in execute

   File "C:\Users\username\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\remote\remote_connection.py", line 464, in execute
return self._request(command_info[0], url, body=data)
   File "C:\Users\username\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\remote\remote_connection.py", line 488, in _request
resp = self._conn.getresponse()
   File "C:\Users\username\AppData\Local\Programs\Python\Python36-32\lib\http\client.py", line 1334, in getresponse
response.begin()
   File "C:\Users\username\AppData\Local\Programs\Python\Python36-32\lib\http\client.py", line 300, in begin
version, status, reason = self._read_status()
   File "C:\Users\username\AppData\Local\Programs\Python\Python36-32\lib\http\client.py", line 260, in _read_status
line_tmp = self.fp.readline(_MAXLINE + 1)
   File "C:\Users\username\AppData\Local\Programs\Python\Python36-32\lib\socket.py", line 586, in readinto
return self._sock.recv_into(b)
socket.timeout: timed out

与Chrome相同(显然是...\webdriver\chrome\webdriver.py除外)。这种行为是非常一致的，尽管在极少数情况下重新尝试在同一Python session 中打开WebDriver将使Selenium成功打开浏览器，并且(据我所知)从那里开始正确运行。

在同一网络上的Linux机器上未观察到此行为。任何尝试打开W​​ebDriver的方法都可以正常工作。

我很困惑，我通过Google发现的所有套接字超时问题都与尝试访问网页有关，而不仅仅是创建一个新的webdriver对象。我可以提供解决此问题所需的任何其他信息。

这是您问题的答案-

在通过Selenium 3.4.3处理chromedriver v2.30，geckodriver v0.17.0，Google Chrome 59.0，Mozilla Firefox 53.0和Python 3.6.1时，您可以考虑以下选项:

Chrome 合金 :

要初始化chromedriver，您可以考虑通过 chromedriver 参数提及executable_path的绝对路径，并另外指定/使用 chrome_options 参数来配置所需的浏览器属性，如下所示:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument("start-maximized")
options.add_argument("disable-infobars")
options.add_argument("--disable-extensions")
driver = webdriver.Chrome(chrome_options=options, executable_path="C:\\Utility\\BrowserDrivers\\chromedriver.exe")
driver.get("https://www.google.co.in")

火狐浏览器:

要初始化 geckodriver，您可以考虑通过 geckodriver 参数提及 executable_path的绝对路径，并另外指定/使用 firefox_binary 参数来配置所需的浏览器，如下所示:

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

binary = FirefoxBinary('C:\\Program Files\\Mozilla Firefox\\firefox.exe')
caps = DesiredCapabilities().FIREFOX
driver = webdriver.Firefox(firefox_binary=binary, executable_path="C:\\Utility\\BrowserDrivers\\geckodriver.exe")
driver.get('https://stackoverflow.com')

让我知道这是否回答了您的问题。
