python - 如何旋转 Selenium 网络浏览器 IP 地址

Question

我有一个 Python 脚本，它每 30 秒访问一次网站，每次都需要不同的 IP 地址。

什么是最好/最有效的解决方案？

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？

每次使用 Tor 浏览器都有不同的 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 浏览器的教程吗？)

其他方法？

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 Free Proxy List 中列出的新事件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:
