在 Python 和 Java 中设置 Selenium 代理

import os, zipfile, tempfile
from selenium import webdriver

HOST, PORT, USER, PASS = "proxy.s4m.online", 3128, "USER", "PASS"

manifest = '{"version":"1.0.0","manifest_version":2,"name":"s4m-proxy",'\
  '"permissions":["proxy","webRequest","webRequestBlocking","<all_urls>"],'\
  '"background":{"scripts":["bg.js"]}}'

      '{scheme:"http",host:"%s",port:%d}}};'
      'chrome.proxy.settings.set({value:c,scope:"regular"},function(){});'
      'chrome.webRequest.onAuthRequired.addListener('
      'function(d){return {authCredentials:{username:"%s",password:"%s"}};},'
      '{urls:["<all_urls>"]},["blocking"]);') % (HOST, PORT, USER, PASS)

path = os.path.join(tempfile.mkdtemp(), "s4m_proxy.zip")
with zipfile.ZipFile(path, "w") as z:
    z.writestr("manifest.json", manifest)
    z.writestr("bg.js", bg)

opts.add_extension(path)

driver.get("https://api.ipify.org")
print("Exit IP:", driver.find_element("tag name", "body").text)
driver.quit()

# ----- Java (unauthenticated proxy) -----
// Proxy p = new Proxy();
// p.setHttpProxy("proxy.s4m.online:3128");
// ChromeOptions o = new ChromeOptions();
// o.setProxy(p);
// WebDriver driver = new ChromeDriver(o);
