如何旋转 Selenium 浏览器 IP 地址

Question

我有一个每 30 秒访问一个网站的 Python 脚本，每次我都需要一个不同的 IP 地址。

最好/最省时的解决方案是什么？

• 在线抓取免费代理？你知道一个从许多来源收集代理的 python 脚本吗？

• 使用 Tor 浏览器每次都有不同的 IP（我在 aws ec2 实例上使用 selenium，你们知道如何在 Ubuntu 服务器上使用 Tor 浏览器的教程？）

• 其他方法？

Answer 1

要收集和使用不同的代理，一个强大的解决方案是使用以下解决方案使用免费代理列表中列出的新活动代理向网站发出代理请求：

• 代码块：

  from selenium import webdriver
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
  from selenium.common.exceptions import TimeoutException
  
  options = webdriver.ChromeOptions()
  options.add_argument("start-maximized")
  options.add_experimental_option("excludeSwitches", ["enable-automation"])
  options.add_experimental_option('useAutomationExtension', False)
  driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
  driver.get("https://sslproxies.org/")
  driver.execute_script("return arguments[0].scrollIntoView(true);", WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//table[@class='table table-striped table-bordered dataTable']//th[contains(., 'IP Address')]"))))
  ips = [my_elem.get_attribute("innerHTML") for my_elem in WebDriverWait(driver, 5).until(EC.visibility_of_all_elements_located((By.XPATH, "//table[@class='table table-striped table-bordered dataTable']//tbody//tr[@role='row']/td[position() = 1]")))]
  ports = [my_elem.get_attribute("innerHTML") for my_elem in WebDriverWait(driver, 5).until(EC.visibility_of_all_elements_located((By.XPATH, "//table[@class='table table-striped table-bordered dataTable']//tbody//tr[@role='row']/td[position() = 2]")))]
  driver.quit()
  proxies = []
  for i in range(0, len(ips)):
      proxies.append(ips[i]+':'+ports[i])
  print(proxies)
  for i in range(0, len(proxies)):
      try:
          print("Proxy selected: {}".format(proxies[i]))
          options = webdriver.ChromeOptions()
          options.add_argument('--proxy-server={}'.format(proxies[i]))
          driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
          driver.get("https://www.whatismyip.com/proxy-check/?iref=home")
          if "Proxy Type" in WebDriverWait(driver, 5).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "p.card-text"))):
              break
      except Exception:
          driver.quit()
  print("Proxy Invoked")
  

• 控制台输出：

Answer 2

网站“https://sslproxies.org/”似乎已更新。这是更新的代码 -

from selenium import webdriver
from selenium.webdriver.common.by import By
import chromedriver_autoinstaller # pip install chromedriver-autoinstaller

chromedriver_autoinstaller.install() # To update your chromedriver automatically
driver = webdriver.Chrome()

# Get free proxies for rotating
def get_free_proxies(driver):
    driver.get('https://sslproxies.org')

    table = driver.find_element(By.TAG_NAME, 'table')
    thead = table.find_element(By.TAG_NAME, 'thead').find_elements(By.TAG_NAME, 'th')
    tbody = table.find_element(By.TAG_NAME, 'tbody').find_elements(By.TAG_NAME, 'tr')

    headers = []
    for th in thead:
        headers.append(th.text.strip())

    proxies = []
    for tr in tbody:
        proxy_data = {}
        tds = tr.find_elements(By.TAG_NAME, 'td')
        for i in range(len(headers)):
            proxy_data[headers[i]] = tds[i].text.strip()
        proxies.append(proxy_data)
    
    return proxies


free_proxies = get_free_proxies(driver)

print(free_proxies)

你会在 python 字典中得到这样的输出 -
