Beluga Proxy

The main scenarios for using a proxy server: bypassing blocking, hiding the real IP, protection of confidential data when connecting to public WiFi access points, interaction with blocked applications, connection to closed portals, forums (which operate only in one country, region).

Scraping data from a community wall on VK (Vkontakte) using the VK API requires authentication and making requests to the API endpoints. VK provides an official API that you can use to access various data, including posts from community walls.

Here's a general guide on how to scrape posts from a community wall using the VK API:

1. Create a VK App:

   • Go to the VK Developers website and create a VK app.
   • Obtain the "App ID" and "Secure Key" for your app.

2. Authentication:

   • Get an access token to authenticate your requests. You can use the Implicit Flow for user authentication or the Client Credentials Flow for app authentication.

3. Make API Requests:

   • Use the obtained access token to make requests to the VK API. The endpoint for getting wall posts is wall.get.
   • You'll need the community's ID or screen name to get its wall posts.

Here's an example using Python and the requests library:

import requests

# Replace with your VK app details and access token
app_id = 'your_app_id'
secure_key = 'your_secure_key'
access_token = 'your_access_token'

# Replace with the community ID or screen name
community_id = 'your_community_id_or_screen_name'

# API endpoint for getting wall posts
api_url = f'https://api.vk.com/method/wall.get?owner_id=-{community_id}&count=10&access_token={access_token}&v=5.131'

# Make the API request
response = requests.get(api_url)
data = response.json()

# Extract and print the posts
if 'response' in data and 'items' in data['response']:
    posts = data['response']['items']
    for post in posts:
        print(post['text'])
else:
    print('Error fetching wall posts')

Note: Make sure to handle errors and check the VK API documentation for more details on available parameters and responses.

If Selenium is not loading the specified browser profile, there are several possible reasons and solutions to investigate. Here are some steps you can take to troubleshoot and resolve the issue:

1. Check Profile Path:

   • Verify that the path to the specified browser profile is correct. Provide the absolute path to the profile directory when setting up the browser profile.

2. Ensure Browser Compatibility:

   • Make sure that the version of Selenium WebDriver you are using is compatible with the version of the browser. Compatibility issues can sometimes cause profile-related problems.

3. Use Browser-Specific Options:

   • Different browsers may have specific options for setting up a profile. For example, in Chrome, you can use user-data-dir to specify the user data directory (profile).

from selenium import webdriver

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--user-data-dir=/path/to/profile')

driver = webdriver.Chrome(options=chrome_options)

• Profile Settings Conflict:

  • Check if there are conflicting settings in the specified profile that might interfere with Selenium. Manually inspect the profile directory to ensure it is in a clean state.

• Clear Browser Cache and Cookies:

  • If you are using an existing profile, clearing the browser cache and cookies might help. Create a clean profile or clear the existing one before running your Selenium script.

• Profile Locking:

  • Ensure that the specified profile is not locked by another instance of the browser. Make sure that no other browser instances are using the same profile concurrently.

• Browser Version Mismatch:

  • If you have recently updated your browser, there might be compatibility issues with the existing profile. Create a new profile or update the existing one to match the browser version.

• Handle Security Restrictions:

  • Some browsers, especially when used in automated testing, may impose security restrictions on loading specific profiles. Review browser settings or consider adjusting security settings to allow profile loading.

• Check for Selenium Updates:

  • Ensure that you are using the latest version of the Selenium WebDriver library. Updates may include fixes for profile-related issues.

• Logging and Debugging:

  • Enable browser and WebDriver logs to capture any error messages or warnings related to the profile. This can provide insights into what might be going wrong.

• Use Browser-Specific Drivers:

  • If you are using a specific browser (e.g., Chrome, Firefox), make sure you are using the appropriate browser-specific WebDriver executable (ChromeDriver, GeckoDriver).

Google Chrome doesn't have a built-in function to work with a proxy server, although there is such an item in the settings. But when you click on it, you are automatically "redirected" to the standard proxy settings in Windows (or any other operating system).

In data centers, proxies are used to provide IP to virtual servers. After all, one server there can be used by a dozen users at the same time. And each needs to be allocated its own IP and port. All this is done through proxies.
