Help connecting to a remote browser using SB syntax

[Abdelgha-4]

I'm trying to use BrightData's Browser API with seleniumbase, I managed to do that using Driver syntax (or raw selenium), but not using SB syntax (which I'm more familiar with).

So this code works:

from selenium.webdriver import ChromeOptions as Options
from selenium.webdriver import Remote
from selenium.webdriver.chromium.remote_connection import (
    ChromiumRemoteConnection as Connection,
)
from seleniumbase import config as sb_config
from seleniumbase.core.browser_launcher import extend_driver

# Initialize sb_config attributes required by extend_driver
if not hasattr(sb_config, "_ext_dirs"):
    sb_config._ext_dirs = []
if not hasattr(sb_config, "recorder_mode"):
    sb_config.recorder_mode = False

SERVER_ADDR = f'https://{AUTH}@brd.superproxy.io:9515'

def scrape(url=TARGET_URL):
    print("Connecting to Browser...")
    connection = Connection(SERVER_ADDR, "goog", "chrome")
    # extend_driver wraps the Remote driver with SeleniumBase page/js methods
    driver = extend_driver(Remote(connection, options=Options()))
    try:
        print(f"Connected! Navigating to {url}...")
        driver.get(url)
        print("Navigated! Using SeleniumBase driver methods...")
        print(f"Title: {driver.page.get_title()}")
        data = driver.page.get_page_source()
        print(f"Scraped! Data length: {len(data)}")
    finally:
        driver.quit()

But not this (simpler) one:

with SB(
    protocol="https",
    servername=f"{AUTH}@brd.superproxy.io",
    port=9515,
) as sb:
    sb.goto(...)

Nor this one:

with SB(
    browser="remote",
    protocol="https",
    servername=f"{AUTH}@brd.superproxy.io",
    port=9515,
    cap_string='{"browserName": "chrome"}',
) as sb:

It seems as if a connection is attempted at port 443 although I specified the port 9515 which could be the issue.

Any help would be appreciated

Set the proxy arg to user:pass@server:port.
Don't use the servername or port args because those are specific to using the Selenium Grid.
If any issues with proxy, add use_chromium=True.

Thank you @mdmintz for pointing me in the right direction, but I see that the protocol is hardcoded to "http" which does not allow me to use https or wss, is this a bug or I'm missing something?

class HTTPApi:
    def __init__(self, addr: Tuple[str, int]):
        self.host, self.port = addr
        self.api = "http://%s:%d" % (self.host, self.port)

[mdmintz]

The http should redirect to https if that option is available. And even if it was an http URL, CDP Mode might not work with a remote browser anyway since SeleniumBase needs to configure the browser (and launch the browser for that configuration to be possible).

[Abdelgha-4]

Sorry this seems beyond my understanding, the conclusion so far is:

• I can't get this to work with SB( nor sb_cdp.Chrome(. (your comment above seems to explain why, it's just that I don't get it)
• It works with seleniumbase if I use extend_driver and Driver syntax (but apparently not in CDP mode).
• It works with raw Selenium, Playwright or Puppeteer.

If anyone manages to connect SeleniumBase CDP mode with BrightData's Browser API, please let me know how.

Thank you so much for your help!

[mdmintz]

It would be easier to use BrightData proxies while launching your own SeleniumBase browser with it.

You're right, I'm only using the remote browser to benefit from their automatic captcha solvers that can solve image classification hCaptcha.
