SeleniumBase+无痕Chrome代理认证弹窗问题求助

使用SeleniumBase开启uc=True（undetected Chrome）模式时，配置带用户名密码认证的代理后，代理认证弹窗反复弹出，无法正常使用代理访问目标网站。

当前使用的代码配置如下：

chrome_options = {
    "headless": False,
    "uc": True,
    "incognito": True
}
chrome_options["proxy"] = f"{username}:{password}@{ip}:{port}"


# Initialize the driver with authenticated proxy
driver = Driver(**chrome_options)

try:
    # Open the target website
    driver.get("https://ipinfo.io/json")
    print("Current IP info:", driver.page_source)
    sleep(10)
finally:
    # Quit the driver
    driver.quit()

已尝试但无效的方案：

• 直接在proxy参数中传入带凭证的代理地址，未被正确识别
• 使用selenium-authenticated-proxy包，无效
• 创建后台运行的Chrome扩展实现代理认证，无效
• 搜索GitHub上相关方案，均无法稳定运行

有效解决方案：适配undetected Chrome的代理认证扩展 #

由于uc=True模式下，undetected-chromedriver会对Chrome启动参数做特殊处理，普通扩展加载方式可能被拦截，需调整扩展创建和加载逻辑，适配SeleniumBase的启动流程：

import os
import zipfile
from seleniumbase import Driver

# 替换为你的代理信息
PROXY_HOST = "你的代理IP"
PROXY_PORT = "你的代理端口"
PROXY_USER = "代理用户名"
PROXY_PASS = "代理密码"

# 生成代理认证扩展（采用Manifest V2，适配undetected Chrome）
manifest_json = """
{
    "version": "1.0.0",
    "manifest_version": 2,
    "name": "Proxy Auth",
    "permissions": [
        "proxy",
        "tabs",
        "storage",
        "<all_urls>",
        "webRequest",
        "webRequestBlocking"
    ],
    "background": {
        "scripts": ["background.js"]
    }
}
"""

background_js = f"""
var config = {{
    mode: "fixed_servers",
    rules: {{
        singleProxy: {{
            scheme: "http",
            host: "{PROXY_HOST}",
            port: parseInt({PROXY_PORT})
        }},
        bypassList: ["localhost"]
    }}
}};

chrome.proxy.settings.set({{value: config, scope: "regular"}}, function() {{}});

function handleAuthRequired(details) {{
    return {{
        authCredentials: {{
            username: "{PROXY_USER}",
            password: "{PROXY_PASS}"
        }}
    }};
}}

chrome.webRequest.onAuthRequired.addListener(
    handleAuthRequired,
    {{urls: ["<all_urls>"]}},
    ["blocking"]
);
"""

# 创建扩展压缩包
def create_proxy_extension():
    plugin_path = "proxy_auth.zip"
    with zipfile.ZipFile(plugin_path, "w") as zp:
        zp.writestr("manifest.json", manifest_json)
        zp.writestr("background.js", background_js)
    return plugin_path

# 初始化Driver并加载扩展
proxy_ext = create_proxy_extension()
chrome_options = {
    "headless": False,
    "uc": True,
    "incognito": True,
    "extension": proxy_ext  # 使用SeleniumBase原生参数加载扩展
}

driver = Driver(**chrome_options)

try:
    driver.get("https://ipinfo.io/json")
    print("当前IP信息:", driver.page_source)
    input("按回车退出...")
finally:
    driver.quit()
    # 清理临时文件
    if os.path.exists(proxy_ext):
        os.remove(proxy_ext)

关键注意点： #

1. 用SeleniumBase自带的extension参数加载扩展，适配uc=True的启动逻辑
2. 扩展采用Manifest V2，避免V3在undetected Chrome中的兼容性问题
3. 若代理为HTTPS协议，需将background.js中的scheme改为"https"
4. 扩展会自动拦截代理认证请求并填充凭证，无需手动操作弹窗
