使用Selenium ChromeDriver连接Socks5代理无法访问网站求助

Your code has three critical issues preventing proxy functionality:

1. Incorrect Proxy Scheme #

You're using a SOCKS5 proxy but configured the extension to use http as the scheme. This breaks proxy routing entirely. Update the scheme value in background_js to socks5:

singleProxy: {
    scheme: "socks5", // Changed from "http"
    host: "{PROXY_HOST}",
    port: parseInt({PROXY_PORT})
},

2. Invalid ChromeDriver Path Setup #

The --chromedriver-executable flag is not a valid Chrome argument. Use Selenium's Service class to specify the driver path (required for Selenium 4+):

from selenium.webdriver.chrome.service import Service

# Inside get_chromedriver()
chromedriver_path = 'C:/Users/User/AppData/Local/Programs/Python/Python311/Scripts/chromedriver-win64/chromedriver.exe'
service = Service(chromedriver_path)
driver = webdriver.Chrome(service=service, options=chrome_options)

3. Manifest V2 Compatibility (Chrome >=115) #

Modern Chrome versions block Manifest V2 extensions by default. Add these flags to re-enable support:

chrome_options.add_argument("--enable-features=LegacyExtensionManifestV2")
chrome_options.add_argument("--disable-features=ExtensionManifestV2Blocklist")

Optional: Migrate to Manifest V3 #

For long-term compatibility, switch to Manifest V3 (Chrome's current standard). Replace your manifest_json and background_js with:

Manifest V3 Code #

manifest_json = f'''
{{
    "version": "1.0.0",
    "manifest_version": 3,
    "name": "Chrome Proxy",
    "permissions": ["proxy", "storage", "webRequest"],
    "host_permissions": ["<all_urls>"],
    "background": {{"service_worker": "background.js"}},
    "minimum_chrome_version": "109.0.0"
}}
'''

background_js = f'''
var config = {{
    mode: "fixed_servers",
    rules: {{
        singleProxy: {{
            scheme: "socks5",
            host: "{PROXY_HOST}",
            port: parseInt({PROXY_PORT})
        }},
        bypassList: ["localhost"]
    }}
}};

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

chrome.webRequest.onAuthRequired.addListener(
    details => ({{
        authCredentials: {{
            username: "{PROXY_USER}",
            password: "{PROXY_PASS}"
        }}
    }}),
    {{urls: ["<all_urls>"]}},
    ['blocking']
);
'''

Additional Troubleshooting Steps #

• Test Proxy Independently: Use curl to verify your proxy works:

  curl --socks5 {PROXY_HOST}:{PROXY_PORT} --proxy-user {PROXY_USER}:{PROXY_PASS} https://httpbin.org/ip
  

• Version Compatibility: Ensure Chrome and ChromeDriver share the same major version.
• Refresh Extension: Delete the old proxy_extension.zip before running the script to avoid using cached files.
