Proxy Laf Gif

Parsing is the collection of all information. Accordingly, parsing a site is copying all of its source code as presented. You can use it to edit the site further or to analyze it for security purposes.

Technically, a proxy is an ordinary computer or server connected to a network (local or Internet). It accepts traffic from the user, redirects it to the address that was specified in the request. And then receives the response from the server and transmits it to the user's equipment. That is, it is actually an intermediary.

To organize multi-threaded scraping through a proxy in C#, you can use the HttpClient class along with tasks and threads. Additionally, you may use proxy rotation to avoid rate limiting and bans. Here's a basic example to get you started:

using System;
using System.Collections.Generic;
using System.Net.Http;
using System.Threading.Tasks;

class Program
{
    static async Task Main()
    {
        // List of proxy URLs
        List proxyList = new List
        {
            "http://proxy1.com:8080",
            "http://proxy2.com:8080",
            // Add more proxies as needed
        };

        // Create HttpClient instances with a different proxy for each thread
        List httpClients = CreateHttpClients(proxyList);

        // List of URLs to scrape
        List urlsToScrape = new List
        {
            "https://example.com/page1",
            "https://example.com/page2",
            // Add more URLs as needed
        };

        // Create tasks for each URL
        List tasks = new List();
        foreach (string url in urlsToScrape)
        {
            tasks.Add(Task.Run(() => ScrapeUrl(url, httpClients)));
        }

        // Wait for all tasks to complete
        await Task.WhenAll(tasks);

        // Dispose of HttpClient instances
        foreach (HttpClient client in httpClients)
        {
            client.Dispose();
        }
    }

    static List CreateHttpClients(List proxies)
    {
        List clients = new List();
        foreach (string proxy in proxies)
        {
            var httpClientHandler = new HttpClientHandler
            {
                Proxy = new WebProxy(proxy),
                UseProxy = true,
            };

            clients.Add(new HttpClient(httpClientHandler));
        }

        return clients;
    }

    static async Task ScrapeUrl(string url, List httpClients)
    {
        // Select a random proxy for this request
        var random = new Random();
        var httpClient = httpClients[random.Next(httpClients.Count)];

        try
        {
            // Make the request using the selected proxy
            HttpResponseMessage response = await httpClient.GetAsync(url);

            // Check if the request was successful
            if (response.IsSuccessStatusCode)
            {
                string content = await response.Content.ReadAsStringAsync();
                // Process the content as needed
                Console.WriteLine($"Scraped {url}: {content.Length} characters");
            }
            else
            {
                Console.WriteLine($"Failed to scrape {url}. Status code: {response.StatusCode}");
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Error scraping {url}: {ex.Message}");
        }
    }
}

In this example:

The CreateHttpClients function creates a list of HttpClient instances, each configured with a different proxy from the provided list.

The ScrapeUrl function performs the actual scraping for a given URL using a randomly selected proxy.

The Main method creates tasks for each URL to be scraped and waits for all tasks to complete.

If Selenium in Python is not able to find the ChromeDriver executable on Linux, there are several common reasons and solutions. Here's a step-by-step guide to troubleshoot and resolve the issue

1. Check ChromeDriver Installation

Ensure that ChromeDriver is installed on your Linux machine. You can download the latest version from the ChromeDriver Downloads page.

2. Specify ChromeDriver Path in Your Script

Explicitly specify the path to ChromeDriver in your Python script using the executable_path argument when initializing the webdriver.Chrome() instance.

from selenium import webdriver

chrome_path = "/path/to/chromedriver"  # Replace with the actual path
driver = webdriver.Chrome(executable_path=chrome_path)

# Your Selenium script...

driver.quit()

3. Add ChromeDriver to System PATH

Add the directory containing ChromeDriver to your system's PATH environment variable. This allows Selenium to automatically locate the ChromeDriver executable.

export PATH=$PATH:/path/to/directory/containing/chromedriver

Alternatively, you can add this line to your shell configuration file (e.g., ~/.bashrc or ~/.bash_profile) to make the change permanent.

4. Check File Permissions

Ensure that the ChromeDriver executable has the necessary execute permissions. You can use the chmod command to add execute permissions if needed.

chmod +x /path/to/chromedriver

5. Use a Virtual Environment

If you are using a virtual environment, ensure that ChromeDriver is installed within the virtual environment. Activate the virtual environment before running your script.

6. Update Selenium and ChromeDriver

Make sure you are using the latest versions of both Selenium and ChromeDriver. Outdated versions may not be compatible with each other.

pip install --upgrade selenium

Download the latest ChromeDriver version from the ChromeDriver Downloads page.

7. Check Chrome Browser Version

Ensure that the version of ChromeDriver you are using is compatible with the version of the Chrome browser installed on your machine. ChromeDriver versions and Chrome browser versions should be in sync.

8. Run in Headless Mode

If you are running your script in headless mode, ensure that your machine has the necessary dependencies for headless browsing.

from selenium import webdriver

chrome_path = "/path/to/chromedriver"  # Replace with the actual path
options = webdriver.ChromeOptions()
options.add_argument('--headless')

driver = webdriver.Chrome(executable_path=chrome_path, options=options)

# Your Selenium script...

driver.quit()

9. Check for Typos

Double-check for any typos or syntax errors in the path to ChromeDriver. Ensure that the path is correct and matches the actual location of the executable.

By addressing these points, you should be able to resolve the issue of Selenium not finding ChromeDriver on Linux. If the problem persists, providing additional details about error messages or behavior would be helpful for further assistance.

When choosing a proxy through which to connect to Skype, pay attention to the stability of its work, the level of anonymity and low load that exceeds the final speed of the connection. Launch the Skype application and open the context menu "Tools". Through the "Advanced" tab, go to "Connection" to open the "Change settings" tab. Here, in the special form, specify the IP address and port, and then click "Save" and restart Skype.
