Proxy Central

In CentOS, if there is no graphical interface (from the terminal), proxy configuration is done through the export http_proxy=http://User:Pass@Proxy:Port/ command. Accordingly, User is the user, Pass is the password to identify you, Proxy is the IP address of the proxy, and Port is the port number. If you have DE, the configuration can be done via Network Manager (as in any other Linux distribution).

In PlayStation 4 and 5, setting up a proxy server follows a similar algorithm. It is necessary to go to the "Library", select "Settings", open the tab "Network Settings". In the window that appears, click on "Network". Then choose the type of connection you are using. It will be offered to set the DHCP, DNS and then the proxy server parameters step by step. And here you can enable it by manually entering the necessary settings.

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.

To upload an image to a website using Selenium, you'll need to locate the file input element on the page and send the image file path to it. Here's a step-by-step guide on how to do this:

Here's an example Python script using Selenium and the Chrome WebDriver that demonstrates these steps:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# Set up the Chrome WebDriver
driver = webdriver.Chrome()

# Navigate to the website
driver.get("https://example.com")

# Wait for the file input element to appear
wait = WebDriverWait(driver, 10)
file_input = wait.until(EC.presence_of_element_located((By.ID, "file-input")))

# Send the image file path to the file input element
image_path = "/path/to/your/image.jpg"
file_input.send_keys(image_path)

# Perform any additional actions after uploading the image
# ...

# Close the browser
driver.quit()

Please replace "https://example.com" with the URL of the website you are working with, and "file-input" with the appropriate ID, name, or other attribute of the file input element on the page. Also, replace "/path/to/your/image.jpg" with the actual file path of the image you want to upload.

Keep in mind that this approach assumes that the file input element has a unique identifier (ID, name, etc.) and that the website's form accepts file inputs in this manner. If the website uses a different method for uploading images (e.g., a custom JavaScript uploader), you'll need to adapt the script accordingly.

It is a service that provides the ability to use a proxy server. It provides connection data (IP address and port number) as well as remote equipment that acts as a "gateway" for transferring traffic.
