Automapper Dynamic Proxies

When scraping paginated content, fetching the "next page" usually involves extracting the URL of the next page from the HTML of the current page. In PHP, you can use a library like Simple HTML DOM Parser to parse HTML and extract the URL for the next page.

Here's an example of how you might scrape the next page URL using PHP

Install Simple HTML DOM Parser:

You can download it from sourceforge and include it in your project, or use Composer:

composer require sunra/php-simple-html-dom-parser

Write a PHP script to scrape the next page URL:

find('a.next-page-link', 0);

    if ($nextPageLink) {
        // Extract the href attribute (URL) from the link
        $nextPageUrl = $nextPageLink->href;
        return $nextPageUrl;
    } else {
        return null; // No next page link found
    }
}

// Example usage
$currentUrl = 'https://example.com/page1'; // Replace with the URL of the current page
$nextPageUrl = scrapeNextPageUrl($currentUrl);

if ($nextPageUrl) {
    echo "Next Page URL: $nextPageUrl";
} else {
    echo "No Next Page URL found.";
}

Replace the $currentUrl variable with the URL of the current page.

Adjust the HTML element selector ('a.next-page-link') based on the structure of the website you are scraping.

Run the script:

Execute the PHP script to see the URL of the next page.

CefSharp is a .NET wrapper for the Chromium Embedded Framework (CEF) that allows you to embed a Chromium browser in your .NET applications. While CefSharp doesn't have a direct replacement for Selenium functions, you can use its own methods to interact with the browser and perform similar actions.

To find elements using XPath in CefSharp, you can use the GetElementById(), GetElementsByClassName(), GetElementsByTagName(), and GetElementsByAttribute() methods provided by the CEFBrowser and CefV8Handler classes.

Here's an example of how you can find elements using XPath in CefSharp:

First, install the CefSharp NuGet package in your project:

Install-Package CefSharp.Minimal

Use the following code to create a CefSharp browser and load a webpage:

using CefSharp.WinForms;
using System;
using System.Drawing;
using System.Windows.Forms;

namespace CefSharpExample
{
    public class Program
    {
        [STAThread]
        public static void Main(string[] args)
        {
            CefSettings settings = new CefSettings();
            settings.BrowserSubprocessPath = "path/to/cef/browser_win32_x64.exe";
            settings.CefCommandLineArgs.Add("--disable-gpu");
            settings.CefCommandLineArgs.Add("--headless");
            Cef.Initialize(settings);

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);

            using (Form mainForm = new Form())
            {
                ChromiumWebBrowser browser = new ChromiumWebBrowser("https://www.example.com");
                mainForm.Controls.Add(browser);
                mainForm.Show();

                // Wait for the browser to initialize
                Application.DoEvents();

                // Load the JavaScript needed to interact with the browser
                browser.EvaluateScriptAsync("document.body.style.behavior = 'url(#default#homepage)'; document.body.style.expression = 'ieUseLinkHover=true';");

                // Wait for the page to load
                Application.DoEvents();

                // Add event handlers for navigation, loading, and error events
                browser.LoadingStateChanged += (sender, args) => { };
                browser.NavigationStateChanged += (sender, args) => { };
                browser.ErrorOccurred += (sender, args) => { };

                // Perform actions on the webpage using the browser object
                // ...

                // Close the browser when done
                browser.Dispose();
            }

            Cef.Shutdown();
        }
    }
}

To find elements using XPath, you can use the CefV8Handler class to execute JavaScript code that locates elements based on the XPath expression. Here's an example of how to find elements using XPath:

using System;
using CefSharp.WinForms;

namespace CefSharpXPathExample
{
    public class Program
    {
        [STAThread]
        public static void Main(string[] args)
        {
            CefSettings settings = new CefSettings();
            settings.BrowserSubprocessPath = "path/to/cef/browser_win32_x64.exe";
            settings.CefCommandLineArgs.Add("--disable-gpu");
            settings.CefCommandLineArgs.Add("--headless");
            Cef.Initialize(settings);

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);

            using (Form mainForm = new Form())
            {
                ChromiumWebBrowser browser = new ChromiumWebBrowser("https://www.example.com");
                mainForm.Controls.Add(browser);
                mainForm.Show();

                // Wait for the browser to initialize
                Application.DoEvents();

                // Load the JavaScript needed to interact with the browser
                browser.EvaluateScriptAsync("document.body.style.behavior = 'url(#default#homepage)'; document.body.style.expression = 'ieUseLinkHover=true';");

                // Wait for the page to load
                Application.DoEvents();

                // Execute JavaScript code to find elements using XPath
                browser.ExecuteScriptAsync("var xpath = arguments[0];" +
                                           "var result = document.evaluate(xpath, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null);" +
                                           "return result.singleNodeValue;", "//*[@id='element-id']");

                // Perform actions on the webpage using the browser object
                // ...

                // Close the browser when done
                browser.Dispose();
            }

            Cef.Shutdown();
        }
    }
}

In this example, we use the ExecuteScriptAsync() method to execute JavaScript code that finds elements using the provided XPath expression. The JavaScript code uses the document.evaluate() method to find the first matched node based on the provided XPath expression.

Keep in mind that the CefSharp library is actively maintained and provides a wide range of features for interacting with the browser. You can find more information and examples in the CefSharp GitHub repository.

Setting up a proxy refers to the process of configuring a system or network to act as an intermediary between a client and a server, allowing for the routing of requests and responses through the proxy server. This can be done for various reasons, such as improving security, anonymity, or performance.

When a proxy is set up, the client sends its requests to the proxy server, which then forwards the requests to the appropriate server on behalf of the client. The proxy server can perform various tasks, such as caching, filtering, and authentication, before returning the response to the client.

There are different types of proxy servers, including HTTP, SOCKS, and Transparent proxies, each with its own set of features and use cases. Setting up a proxy can be done on various levels, such as on an individual computer, a local network, or a large-scale enterprise network.

To configure a Socks5 proxy for Chrome in Selenium using Python, you can use the --proxy-server command-line option with the Socks5 proxy address. Here's an example using the webdriver.Chrome class in Python:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService

# Socks5 proxy configuration
socks5_proxy = "socks5://127.0.0.1:1080"  # Replace with your actual Socks5 proxy address

# Configure Chrome options with proxy settings
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument(f'--proxy-server={socks5_proxy}')

# Create a Chrome WebDriver instance with the configured options
chrome_service = ChromeService(executable_path="path/to/chromedriver")  # Replace with the actual path
driver = webdriver.Chrome(service=chrome_service, options=chrome_options)

# Example: Navigate to a website using the configured proxy
driver.get("https://www.example.com")

# Perform other actions with the WebDriver as needed

# Close the browser window
driver.quit()

- Replace "socks5://127.0.0.1:1080" with the actual Socks5 proxy address you want to use.
- Download the ChromeDriver executable from the official ChromeDriver download page and provide the path to the executable in the executable_path parameter of ChromeService.
- Update the driver.get() method to navigate to the website you want.

Make sure to have the selenium library installed (pip install selenium) and ensure that the ChromeDriver version is compatible with the Chrome browser installed on your system.

Telegram is a popular messenger, the activity of which is prohibited in some countries. It is possible to bypass the blocking with the help of anonymous proxy-servers working on the SOCKS5 protocol. They redirect traffic from Telegram to third-party IP addresses from other countries. Proxy servers guarantee the anonymity of correspondence, allow you to create chatbots, promote several accounts simultaneously, which will not be afraid of blocking.
