我正在使用以下代码：
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)
如何在Python WebDriver中设置Chrome代理？这段代码可以在Firefox中运行，但是对于Chrome来说该怎么设置代理呢？我找到了这个例子，但并没有太大帮助。当我运行脚本时，没有任何反应（Chrome浏览器未启动）。
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")
WebDriverException: 消息：'chromedriver' 可执行文件需要在 PATH 中。请参见 https://sites.google.com/a/chromium.org/chromedriver/home - Kishan Mehta对我来说它正在工作...
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")
scheme://user:pass@my.great.host:port。其中，scheme代表协议，user和pass分别表示用户名和密码，my.great.host表示主机名，port表示端口号。 - Nate Symer我曾遇到同样的问题。ChromeOptions很奇怪，因为它并没有像你想象的那样与desiredcapabilities集成。我忘了具体的细节，但基本上，根据你是否传递了一个desired capabilities字典，ChromeOptions将重置某些值为默认值。
我进行了以下猴子补丁，使我能够指定自己的字典，而不用担心ChromeOptions的复杂性。
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
所有改变的仅是 "skip_capabilities_update" 关键字参数。现在我只需这样设置自己的字典：
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 )
很容易！
首先，定义您的代理网址。
proxy_url = "127.0.0.1:9009"
proxy = Proxy({
'proxyType': ProxyType.MANUAL,
'httpProxy': proxy_url,
'sslProxy': proxy_url,
'noProxy': ''})
然后，创建Chrome的能力设置并将代理添加到其中。
capabilities = webdriver.DesiredCapabilities.CHROME
proxy.add_to_capabilities(capabilities)
最后，创建WebDriver并传递所需的功能
driver = webdriver.Chrome(desired_capabilities=capabilities)
driver.get("http://example.org")
总的来说，它看起来是这样的
from selenium import webdriver
from selenium.webdriver.common.proxy import *
proxy_url = "127.0.0.1:9009"
proxy = Proxy({
'proxyType': ProxyType.MANUAL,
'httpProxy': proxy_url,
'sslProxy': proxy_url,
'noProxy': ''})
capabilities = webdriver.DesiredCapabilities.CHROME
proxy.add_to_capabilities(capabilities)
driver = webdriver.Chrome(desired_capabilities=capabilities)
driver.get("http://example.org")
像魔术一样起作用：
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
}
对于那些想在需要身份验证的Chrome中设置代理服务器的人，应该遵循以下步骤。
