Vue 3 Proxy

There are special online services that use IP and HTTP connection tags to determine if a proxy is being used from your equipment. The most popular are Proxy Checker, Socproxy.

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.

To enter the browser in normal mode via Selenium WebDriver, you need to set the desired capabilities for the browser you want to use. Here's an example of how to do this in Python:

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

# Set the desired capabilities for the browser
desired_caps = DesiredCapabilities.CHROME
desired_caps['browserName'] = 'chrome'
desired_caps['version'] = 'latest'

# Initialize the WebDriver with the desired capabilities
driver = webdriver.Chrome(desired_capabilities=desired_caps)

# Open a web page in normal mode
driver.get('https://www.example.com')

# Do some actions on the web page
# ...

# Close the browser
driver.quit()

In this example, we are using the Chrome browser, but you can replace 'chrome' with any other browser that Selenium supports, such as 'firefox', 'edge', or 'safari'. The 'version' parameter is set to 'latest', which means that the latest version of the browser will be used.

Note that the DesiredCapabilities class is deprecated in the latest versions of Selenium. Instead, you can use the ChromeOptions class for Chrome or the FirefoxOptions class for Firefox to set the desired capabilities. Here's an example using ChromeOptions:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

# Set the desired capabilities for the browser
chrome_options = Options()
chrome_options.add_argument('--start-maximized')  # Optional: start the browser in full screen

# Initialize the WebDriver with the desired capabilities
driver = webdriver.Chrome(options=chrome_options)

# Open a web page in normal mode
driver.get('https://www.example.com')

# Do some actions on the web page
# ...

# Close the browser
driver.quit()

This will also open the Chrome browser in normal mode.

To create your own proxy server, you can use open-source software such as Privoxy or Squid. Here's a step-by-step guide using Privoxy:

Install Privoxy: Download the latest version of Privoxy from the official website (https://www.privoxy.org/download/) and install it on your computer. The installation process varies depending on your operating system.

Configure Privoxy: After installing Privoxy, open the configuration file, usually located at /etc/privoxy/config.txt on Linux or C:\Program Files\Privoxy\config\config.txt on Windows. You can also find the configuration file in the installation directory.

Edit the configuration file: Open the configuration file in a text editor and make the following changes:

Uncomment the following line by removing the # symbol at the beginning:

listen-address 0.0.0.0

Uncomment the following line and change the port number if desired (e.g., 8118):

listen-port 8118

forward-suffix .privoxy

Add the following line to forward requests to a specific destination server (replace with the desired server's address):

forward-suffix 

Save the configuration file and restart Privoxy: Close the text editor and restart Privoxy to apply the changes. On Linux, you can use the following command:

sudo /etc/init.d/privoxy restart

On Windows, locate the Privoxy service in the Windows Services list and restart it.

Test your proxy server: Open a web browser and configure it to use your new proxy server (e.g., http://localhost:8118). Test by accessing a website to ensure that the proxy server is working correctly.
