Helix Proxy

If your proxy gives you a 504 error, it means the server failed to complete the request within the time period you specified. Refreshing the page may help. Another option is to switch to another browser. You can also use the incognito mode, pre-clearing the browser cache. Pay attention to plug-ins that can also cause this error.

To add a custom method to a Selenium module, you can extend the existing Selenium class and add your method to the subclass. Here's an example in Python using Selenium WebDriver

Let's say you want to add a custom method named custom_method to the WebElement class in Selenium:

from selenium.webdriver.remote.webelement import WebElement

# Define your custom method
def custom_method(self, arg1, arg2):
    # Your custom logic here
    print(f"Custom Method: {arg1}, {arg2}")

# Add the custom method to the WebElement class
WebElement.custom_method = custom_method

# Now, you can use the custom method on any WebElement instance
driver = webdriver.Chrome()
element = driver.find_element(By.XPATH, "//input[@name='username']")
element.custom_method("arg1_value", "arg2_value")

In this example:

1. We import the WebElement class from selenium.webdriver.remote.webelement.
2. We define a custom method custom_method that takes two arguments (arg1 and arg2) and prints a message.
3. We add the custom method to the WebElement class by assigning it as an attribute (WebElement.custom_method).
4. We create a WebDriver instance and find a WebElement on the page using a locator (e.g., By.XPATH).
5. We call the custom method on the WebElement instance, passing the desired arguments.

This approach allows you to extend Selenium's classes with your custom methods. Keep in mind that modifying the core Selenium classes may have consequences, and you should be careful not to override existing methods or cause conflicts with future updates.

To save cookies in SQLite3 using Selenium, you'll need to follow these steps:

1. Install the required packages: Make sure you have Selenium and SQLite3 installed. You can install SQLite3 using pip:

pip install sqlite3

2. Connect to the SQLite3 database: Before saving cookies to SQLite3, you need to establish a connection to the database.

import sqlite3

# Connect to the SQLite3 database (or create it if it doesn't exist)
conn = sqlite3.connect("cookies.db")
cursor = conn.cursor()

# Create the cookies table if it doesn't exist
cursor.execute("""
CREATE TABLE IF NOT EXISTS cookies (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    name TEXT NOT NULL,
    value TEXT NOT NULL,
    domain TEXT NOT NULL,
    path TEXT NOT NULL,
    expiry TEXT NOT NULL
)
""")

# Commit the changes and close the connection
conn.commit()
conn.close()

3. Save cookies to SQLite3 using Selenium: In your Selenium code, you can save cookies to the SQLite3 database by iterating through the cookies in the browser and inserting them into the database.

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
import sqlite3

# Set the path to the ChromeDriver executable
chrome_driver_path = "path/to/chromedriver"

# Set the preference to save downloaded files with a specific name pattern
options = Options()
options.add_argument("download.default_directory='path/to/download/folder'")
options.add_argument(f"download.download_path='path/to/download/folder'")
options.add_preference("download.filename_template", "%f - %r")

# Initialize the Chrome WebDriver with the specified options
driver = webdriver.Chrome(executable_path=chrome_driver_path, options=options)

# Your Selenium code goes here

# Connect to the SQLite3 database
conn = sqlite3.connect("cookies.db")
cursor = conn.cursor()

# Get all cookies from the browser
cookies = driver.get_cookies()

# Insert cookies into the SQLite3 database
for cookie in cookies:
    cursor.execute("""
    INSERT INTO cookies (name, value, domain, path, expiry)
    VALUES (?, ?, ?, ?, ?)
    """, (cookie['name'], cookie['value'], cookie['domain'], cookie['path'], cookie['expiry']))

# Commit the changes and close the connection
conn.commit()
conn.close()

# Your code to save the cookies to SQLite3

# Close the browser
driver.quit()

Replace path/to/chromedriver, path/to/download/folder, and %f - %r with the appropriate values for your setup.

This example saves the cookies from the browser to the SQLite3 database. You can modify the code to load cookies from the database and set them in the browser as needed.

In JavaScript with Selenium, you can save and reuse cookies using the WebDriver's manage().getCookies() and manage().addCookie() methods. Here's a simple example:

const { Builder } = require('selenium-webdriver');
const firefox = require('selenium-webdriver/firefox');

// Create a new instance of the Firefox driver
const driver = new Builder()
  .forBrowser('firefox')
  .setFirefoxOptions(new firefox.Options().headless())
  .build();

// Navigate to a webpage
async function navigateToPage() {
  await driver.get('https://example.com');
}

// Save cookies
async function saveCookies() {
  const cookies = await driver.manage().getCookies();
  // Save the cookies to a file or some storage mechanism
  // For simplicity, we'll just print them here
  console.log('Cookies:', cookies);
}

// Reuse cookies
async function reuseCookies(savedCookies) {
  // Delete existing cookies
  await driver.manage().deleteAllCookies();

  // Add the saved cookies to the browser session
  for (const cookie of savedCookies) {
    await driver.manage().addCookie(cookie);
  }

  // Navigate to a page to apply the cookies
  await navigateToPage();
}

// Example usage
(async () => {
  await navigateToPage(); // Navigate to the page and set some initial cookies

  await saveCookies(); // Save the cookies

  // Close and reopen the browser or navigate to a different page
  // ...

  // Reuse the saved cookies
  await reuseCookies(savedCookies);
})();

The navigateToPage function navigates to a webpage and sets some initial cookies.

The saveCookies function retrieves the current cookies using manage().getCookies() and prints them. You would typically save them to a file or some storage mechanism.

The reuseCookies function deletes existing cookies, then adds the saved cookies back to the browser session using manage().addCookie(). It then navigates to a page to apply the cookies.

The example usage section demonstrates how to use these functions in a sequence.

It means organizing a connection through several VPN-servers at once. It is used to protect confidential data as much as possible or to hide one's real IP address. This principle of connection is used, for example, in the TOR-browser. That is, when all traffic is sent immediately through a chain of proxy servers.
