DigitalOcean Proxy

To install a proxy server in Google Chrome, you must do the following steps:

Open the browser.
Click the "?" icon in the upper right corner.
Go to "Settings".
Select the "Advanced" option.
Click the "System" tab.
Click on "Open proxy settings for your computer".
Click on "Network settings".
Activate the "Use proxy server" option.
In the tab that opens, specify the IP address of the proxy server. You must enter the address in the field of the protocol to which the proxy server belongs. You can get this information from the provider. Click the "OK" button to save your settings.

Popup scraping typically involves interacting with web pages that have dynamic content, including popups or modals. To scrape data from popups, you may need to use a headless browser automation library. One popular choice is Selenium, which provides a WebDriver API for interacting with browsers.

Here's an example using Python and Selenium to scrape data from a webpage with a popup

Install Selenium:

pip install selenium

• Download WebDriver:

  • Download the WebDriver for the browser you want to use. In this example, I'll use ChromeDriver. Download it from ChromeDriver Downloads and place the executable in your project directory or in a directory listed in your system's PATH.

• Write the Scraping Code:

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

def scrape_with_popup(url):
    # Set up the WebDriver (make sure the WebDriver executable is in the same directory or in your PATH)
    driver = webdriver.Chrome()

    try:
        # Open the webpage
        driver.get(url)

        # Locate and click the button/link that triggers the popup
        popup_trigger = driver.find_element(By.ID, 'popup-trigger')
        popup_trigger.click()

        # Wait for the popup to appear (adjust the timeout as needed)
        WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID, 'popup-content')))

        # Extract data from the popup
        popup_content = driver.find_element(By.ID, 'popup-content').text
        print("Popup Content:", popup_content)

    finally:
        # Close the browser window
        driver.quit()

# Replace 'https://example.com' with the actual URL of the webpage
scrape_with_popup('https://example.com')

3. • Replace 'https://example.com' with the actual URL of the webpage you want to scrape.
   • Replace 'popup-trigger' and 'popup-content' with the actual IDs or other locators of the elements triggering the popup and the popup content.

4. Run the Code:

   • Execute the Python script, and it will open a browser, interact with the webpage, and print the content of the popup.

This example assumes that the webpage you are working with uses a trigger element (button/link) to open the popup.

To simulate manual text input in Selenium WebDriver, you can use the send_keys method to send a sequence of keys to an input field. Here's an example of how to do this in Python:

Install the required package:

pip install selenium

Create a method to simulate manual text input:

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

def simulate_manual_text_input(driver, locator, text_to_send):
    element = WebDriverWait(driver, 10).until(EC.visibility_of_element_located(locator))
    element.clear()
    element.send_keys(text_to_send)

Use the simulate_manual_text_input method in your test code:

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 WebDriver
driver = webdriver.Chrome()
driver.maximize_window()

# Navigate to the target web page
driver.get("https://www.example.com")

# Locate the input field
locator = (By.ID, "username")

# Simulate manual text input
simulate_manual_text_input(driver, locator, "your_username")

# Perform any additional actions as needed

# Close the browser
driver.quit()

In this example, we first create a method called simulate_manual_text_input that takes a driver instance, a locator tuple containing the locator strategy and locator value, and a text_to_send string containing the text to send to the input field. Inside the method, we use the WebDriverWait class to wait for the element to become visible and then clear the input field and send the text using the send_keys method.

In the test code, we set up the WebDriver, navigate to the target web page, and locate the input field using the locator variable. We then call the simulate_manual_text_input method with the driver, locator, and "your_username" as input. After simulating the manual text input, you can perform any additional actions as needed.

Remember to replace "https://www.example.com", "username", and "your_username" with the actual URL, input field ID or name, and the text you want to type into the input field.

To emulate mouse wheel scrolling and keystrokes in Selenium WebDriver with Node.js, you can use the Actions class to perform these actions. Here's an example that demonstrates scrolling and sending keystrokes:

const { Builder, By, Key } = require('selenium-webdriver');

(async function example() {
  // Create a new instance of the WebDriver
  const driver = await new Builder().forBrowser('chrome').build();

  try {
    // Navigate to a webpage
    await driver.get('https://example.com');

    // Perform mouse wheel scrolling
    await driver.actions().move({ x: 0, y: 0 }).sendKeys(Key.PAGE_DOWN).perform();
    await driver.sleep(1000); // Sleep for 1 second to see the effect

    // Perform keystrokes in an input field
    const inputField = await driver.findElement(By.css('input[type="text"]'));
    await inputField.sendKeys('Hello, this is some text.');
    await driver.sleep(1000); // Sleep for 1 second to see the effect

  } finally {
    // Close the browser window
    await driver.quit();
  }
})();

- driver.actions() creates an instance of the Actions class.
- move({ x: 0, y: 0 }) is used to position the mouse at coordinates (0, 0).
- sendKeys(Key.PAGE_DOWN) performs a mouse wheel scrolling action. You can replace Key.PAGE_DOWN with other keys or combinations according to your needs.
- sendKeys() is also used to input text into an input field. The inputField variable is a reference to the input field on the webpage, and sendKeys() is called to type text into it.

Make sure to replace the URL in driver.get('https://example.com') with the URL of the webpage you are working on, and adjust the CSS selector for the input field according to your webpage's structure.

Additionally, you may need to install the selenium-webdriver package if you haven't already:

npm install selenium-webdriver

On smartphones, when a proxy is turned on, the corresponding indicator (the "VPN" icon) appears in the status bar. In Windows you have to go to "Settings", open "Network and Internet". Under "Proxy Server", if the item "Manual" is activated, it means that the proxy is engaged right now.
