Question

我使用webdriver配置路由器，但是当我运行脚本时：

from selenium import webdriver
self.driver = webdriver.Chrome()

它打开chrome并且没有响应，然后引发异常：

chrome无法访问。

我的电脑有两张网卡，当我禁用一张网卡时，效果很好。我不知道为什么，请帮忙！

Answer 1

在纯粹的情况下＆＃34;镀铬无法到达＆＃34;表示可以启动Chrome二进制文件，但无法访问调试端口。

调试端口由参数设置： - remote-debugging-port = 12582

在我的情况下，它发生是因为沙盒的一些问题：

ps afvvx | grep chrome

/opt/google/chrome/chrome --disable-background-networking --disable-client-side-phishing
21026 pts/2    S+     0:00      0    47  6008   100  0.0  |           \_ cat
21027 pts/2    S+     0:00      0    47  6008   100  0.0  |           \_ cat
21029 pts/2    Z+     0:00      0     0     0     0  0.0  |           \_ [chrome-sandbox] <defunct>

当我运行/ opt / google / chrome / chrome-sandbox

时

# /opt/google/chrome/chrome-sandbox  -h
The setuid sandbox provides API version 1, but you need 0
Please read [https://code.google.com/p/chromium/wiki/LinuxSUIDSandboxDevelopment][1].

从上面的url我无法获得修复SUID SandBox的操作，但可以通过Chrome arg --disable-setuid-sandbox关闭它（有时使用--no-sandbox ）：

import time
from selenium import webdriver

from xvfbwrapper import Xvfb

vdisplay = Xvfb()
vdisplay.start()

from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument("--disable-setuid-sandbox")

driver = webdriver.Chrome('/usr/local/sbin/chromedriver', chrome_options=chrome_options)  # Optional argument, if not specified will search path.
driver.get('http://www.google.com/xhtml');
time.sleep(5) # Let the user actually see something!
search_box = driver.find_element_by_name('q')
search_box.send_keys('ChromeDriver')
search_box.submit()
time.sleep(5) # Let the user actually see something!
driver.quit()

vdisplay.stop()

另一种情况是，当没有像dbus-X11那样安装某个软件包时：

/opt/google/chrome/google-chrome --no-sandbox --disable-setuid-sandbox --disable-background-networking --disable-client-side-phishing-detection --disable-component-update --disable-default-apps --disable-hang-monitor --disable-prompt-on-repost --disable-sync --disable-web-resources --enable-logging --ignore-certificate-errors --load-extension=/tmp/.com.google.Chrome.a0gQAp/internal --log-level=0 --metrics-recording-only --no-first-run --password-store=basic --remote-debugging-port=12512 --safebrowsing-disable-auto-update --safebrowsing-disable-download-protection --test-type=webdriver --use-mock-keychain --user-data-dir=/tmp/.com.google.Chrome.dgq4j1 data:,

只需安装：

即可

apt-get install dbus-X11

'selenium.common.exceptions.WebDriverException：消息：u'chrome无法访问
