Selenium proxy server argument - unknown error: net::ERR_TUNNEL_CONNECTION_FAILED
Selenium proxy server argument - unknown error: net::ERR_TUNNEL_CONNECTION_FAILED
希望你一切都好。
我在尝试设置 chrome 网络驱动程序时遇到了一个小问题。我正在尝试更改 webdriver 的参数以轮换用户代理和 IP（我将其用于抓取目的并且不想使用相同的 IP 和 UA）。
当我传递 UA 参数时，一切正常。但是当我添加 IP 参数时，由于某些我无法确定的原因，它会系统地失败。我总是收到以下错误
WebDriverException: unknown error: net::ERR_TUNNEL_CONNECTION_FAILED
(Session info: chrome=86.0.4240.198)```
行为始终相同，驱动程序按要求打开网页，然后页面加载一段时间，直到指示该站点不可访问。
下面是使用的代码。你知道它可能来自哪里吗？ （不幸的是，我找不到类似的帖子）
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
opts = Options()
user_agent = 'Mozilla/5.0 CK={} (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko'
PROXY = '176.9.119.170:8080'
opts.add_argument("user-agent="+user_agent)
opts.add_argument("--proxy-server=%s" % PROXY)
driver = webdriver.Chrome(executable_path='XXXXXXXX', options=opts)
driver.get('https://www.expressvpn.com/what-is-my-ip')
user_agent_check = driver.execute_script("return navigator.userAgent;")
print(user_agent_check)

下面是在chrome,
中添加代理的正确方法
JAVA:
ChromeOptions chromeOptions = new ChromeOptions();
String proxyadd = "176.9.119.170:8080";
Proxy proxy = new Proxy();
proxy.setHttpProxy(proxyadd);
proxy.setSslProxy(proxyadd);
chromeOptions.setCapability("proxy", proxy);
WebDriver driver = new ChromeDriver(chromeOptions);
PYTHON:
from selenium import webdriver
PROXY="176.9.119.170:8080"
webdriver.DesiredCapabilities.CHROME['proxy'] = {
"httpProxy": PROXY,
"ftpProxy": PROXY,
"sslProxy": PROXY,
"proxyType": "MANUAL",
}
webdriver.DesiredCapabilities.CHROME['acceptSslCerts']=True
driver =webdriver.Chrome(r".\chromedriver.exe")
driver.get("https://www.google.com")
似乎 chrome 无法连接到代理，可能是它正在使用系统代理。试试上面提到的设置代理的方法
完整代码：
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
PROXY="localhost:8888"
opts = Options()
user_agent = 'Mozilla/5.0 CK={} (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko'
webdriver.DesiredCapabilities.CHROME['proxy'] = {
"httpProxy": PROXY,
"ftpProxy": PROXY,
"sslProxy": PROXY,
"proxyType": "MANUAL",
}
webdriver.DesiredCapabilities.CHROME['acceptSslCerts']=True
opts.add_argument("user-agent="+user_agent)
print(webdriver.DesiredCapabilities.CHROME)
driver =webdriver.Chrome(r".\chromedriver.exe",options=opts)
driver.get("https://wrong.host.badssl.com/")
driver.get('https://www.expressvpn.com/what-is-my-ip')
user_agent_check = driver.execute_script("return navigator.userAgent;")
