Question

我正在使用此代码：

profile = webdriver.FirefoxProfile()
profile.set_preference("network.proxy.type", 1)
profile.set_preference("network.proxy.http", "proxy.server.address")
profile.set_preference("network.proxy.http_port", "port_number")
profile.update_preferences()
driver = webdriver.Firefox(firefox_profile=profile)

在python webdriver中为FF设置代理。这适用于FF。如何在Chrome中设置这样的代理？我找到了这个exmaple，但不是很有帮助。当我运行脚本时没有任何反应（Chrome浏览器未启动）。

Answer 1

from selenium import webdriver

PROXY = "23.23.23.23:3128" # IP:PORT or HOST:PORT

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--proxy-server=%s' % PROXY)

chrome = webdriver.Chrome(options=chrome_options)
chrome.get("http://whatismyipaddress.com")

Answer 2

它为我工作......

from selenium import webdriver

PROXY = "23.23.23.23:3128" # IP:PORT or HOST:PORT

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--proxy-server=http://%s' % PROXY)

chrome = webdriver.Chrome(chrome_options=chrome_options)
chrome.get("http://whatismyipaddress.com")

Answer 3

我遇到了同样的问题。 ChromeOptions非常奇怪，因为它没有像您想象的那样与所需的功能集成。我忘记了确切的细节，但基本上ChromeOptions会根据您是否通过所需的功能dict重置为默认值。

我做了以下猴子补丁，允许我指定自己的字典而不用担心ChromeOptions的并发症

更改/selenium/webdriver/chrome/webdriver.py中的以下代码：

def __init__(self, executable_path="chromedriver", port=0,
             chrome_options=None, service_args=None,
             desired_capabilities=None, service_log_path=None, skip_capabilities_update=False):
    """
    Creates a new instance of the chrome driver.

    Starts the service and then creates new instance of chrome driver.

    :Args:
     - executable_path - path to the executable. If the default is used it assumes the executable is in the $PATH
     - port - port you would like the service to run, if left as 0, a free port will be found.
     - desired_capabilities: Dictionary object with non-browser specific
       capabilities only, such as "proxy" or "loggingPref".
     - chrome_options: this takes an instance of ChromeOptions
    """
    if chrome_options is None:
        options = Options()
    else:
        options = chrome_options

    if skip_capabilities_update:
        pass
    elif desired_capabilities is not None:
        desired_capabilities.update(options.to_capabilities())
    else:
        desired_capabilities = options.to_capabilities()

    self.service = Service(executable_path, port=port,
        service_args=service_args, log_path=service_log_path)
    self.service.start()

    try:
        RemoteWebDriver.__init__(self,
            command_executor=self.service.service_url,
            desired_capabilities=desired_capabilities)
    except:
        self.quit()
        raise 
    self._is_remote = False

所有改变的是“skip_capabilities_update”kwarg。现在我这样做是为了设置我自己的词：

capabilities = dict( DesiredCapabilities.CHROME )

if not "chromeOptions" in capabilities:
    capabilities['chromeOptions'] = {
        'args' : [],
        'binary' : "",
        'extensions' : [],
        'prefs' : {}
    }

capabilities['proxy'] = {
    'httpProxy' : "%s:%i" %(proxy_address, proxy_port),
    'ftpProxy' : "%s:%i" %(proxy_address, proxy_port),
    'sslProxy' : "%s:%i" %(proxy_address, proxy_port),
    'noProxy' : None,
    'proxyType' : "MANUAL",
    'class' : "org.openqa.selenium.Proxy",
    'autodetect' : False
}

driver = webdriver.Chrome( executable_path="path_to_chrome", desired_capabilities=capabilities, skip_capabilities_update=True )

Answer 4

对于那些询问如何在chrome中设置需要身份验证的代理服务器的人们，请遵循以下步骤。

在您的项目中创建proxy.py文件，使用此code并从
调用proxy_chrome 每次需要时使用proxy.py。您需要传递参数（例如代理服务器，端口和用户名密码）进行身份验证。

Answer 5

这对我来说就像一种魅力：

proxy = "localhost:8080"
desired_capabilities = webdriver.DesiredCapabilities.CHROME.copy()
desired_capabilities['proxy'] = {
    "httpProxy": proxy,
    "ftpProxy": proxy,
    "sslProxy": proxy,
    "noProxy": None,
    "proxyType": "MANUAL",
    "class": "org.openqa.selenium.Proxy",
    "autodetect": False
}

Answer 6

from selenium import webdriver
from selenium.webdriver.common.proxy import *

myProxy = "86.111.144.194:3128"
proxy = Proxy({
    'proxyType': ProxyType.MANUAL,
    'httpProxy': myProxy,
    'ftpProxy': myProxy,
    'sslProxy': myProxy,
    'noProxy':''})

driver = webdriver.Firefox(proxy=proxy)
driver.set_page_load_timeout(30)
driver.get('http://whatismyip.com')
