如何旋转Selenium webrowser IP地址

Question

我有一个Python脚本，每30秒访问一个网站，每次都需要一个不同的IP地址。在

最佳/最具时效性的解决方案是什么？在

• 在线获取免费代理？你知道一个从许多来源收集代理的python脚本吗？

• 每次使用torbrowser都有一个不同的IP（我在awsec2实例上使用selenium，你们知道如何在Ubuntu服务器上使用torbrowser的教程吗？）

• 其他方法？

Answer 1

要收集和使用不同的代理，一个可靠的解决方案是使用新的活动代理对网站发出代理请求，这些代理在Free Proxy List中列出，使用以下解决方案：

• 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")
