    'password': 'your-key-password'
}

with sync_playwright() as p:
    # Launch browser with proxy
    browser = p.chromium.launch(proxy=proxy_settings)
    page = browser.new_page()

    # Navigate and maintain session
    page.goto('https://httpbin.org/ip')
    print(page.content())

    # Close browser
    browser.close()

By specifying SESSIONID, you make sure that all requests from this session use the same proxy IP, offering consistency in scraped data and minimizing bans.

Handling Authentication in Your Script

During web scraping, you might run into pages that require authentication. Playwright makes it easy to manage these situations. Imagine trying to log into a dashboard to glean data for your analytics app. With Playwright, all it takes is a few savvy changes to your script. Here's how you can handle basic HTTP authentication directly in your script:

from playwright.sync_api import sync_playwright

# Proxy with authentication
credentials = {
    'server': 'http://x.botproxy.net:8080',
    'username': 'your-user-key',
    'password': 'your-key-password'
}

with sync_playwright() as p:
    browser = p.chromium.launch(proxy=credentials)
    page = browser.new_page()

    # Visit site with authentication
    page.authenticate({
        'username': 'your-site-username',
        'password': 'your-site-password'
    })
    page.goto('https://protected-site.com')

    # Print the page content
    print(page.content())

    browser.close()

With BotProxy, you ensure that not only do you successfully authenticate yourself to target sites, but you also do so anonymously, thanks to rotating proxies and session control.

def run(playwright):
    # Launch the browser
    browser = playwright.chromium.launch(headless=True)
    context = browser.new_context()
    page = context.new_page()

    # Navigate to the job listings page
    page.goto('https://example-job-listings.com')

    # Select job titles using a selector
    job_titles = page.locator('.job-title-class').all_inner_texts()

    # Print each job title
    for title in job_titles:
        print(title)

    # Cleanup
    context.close()
    browser.close()

with sync_playwright() as playwright:
    run(playwright)

In this script, you launch a Chromium browser in headless mode and navigate to a hypothetical job listings page. Using CSS selectors, you extract and print job titles, simulating a real browsing session that can bypass client-side rendering challenges.

The Strategic Role of Proxies

Incorporating Playwright with proxies can prevent common scraping hurdles like IP bans or geo-restrictions. This is where a service like BotProxy proves invaluable. By routing your requests through rotating proxies, you not only mimic human behavior more effectively but also navigate around access barriers set by the target websites.

By diagnosing your errors, you can pinpoint whether the issue lies within your script's logic, an external service, or your network setup.

Using Playwright's Debugging Tools

Browser Developer Tools: Playwright allows you to launch browsers in a non-headless mode, which is invaluable for observing real-time interactions. You can see how your selectors interact with elements and view JavaScript console outputs directly in the browser.

browser = playwright.chromium.launch(headless=False)  # Not headless - watch actions in real-time

Verbose Logging: Enable verbose logging to capture detailed information about requests, responses, and other script actions. This data can shed light on where and why an error might be occurring.

PYTHON_NODE_OPTIONS="--trace-warnings" python your_script.py

Error Screenshooting: Playwright can capture screenshots when an error occurs, giving you a visual of the page at the time of failure. 

try:
    page.goto('https://example.com')
except Exception as e:
    page.screenshot(path='error_screenshot.png')
    print(f"An error occurred: {e}")

Leveraging Playwright and BotProxy Together

When using proxies through BotProxy, ensure your authentication details are correct. Sometimes a failure to connect is due to incorrect proxy settings or credentials.

Example: Checking Proxy Configuration

Ensure your proxy settings in Playwright are matching your BotProxy credentials.

    'username': 'your-user-key',
    'password': 'your-key-password'
}

browser = playwright.chromium.launch(proxy=proxy_settings)

Practicing Graceful Error Recovery

Implement error handling logic that allows your script to retry operations or gracefully log the issue for further analysis. This can prevent your script from breaking abruptly and help you pinpoint sporadic issues.

max_retries = 3
for attempt in range(max_retries):
    try:
        page.goto('https://example.com')
        break  # exit loop if successful
    except Exception as e:
        print(f"Attempt {attempt + 1} failed: {e}")
        if attempt == max_retries - 1:
            print("Max retries reached. Terminating.")

Wrapping Up

Debugging and error handling are as much an art as a science. While Playwright provides you with robust tools and features, the mindset and strategy you bring to the table can make all the difference.
