Defiler Proxy

The first thing to do is to find a suitable proxy server with an IP address and port. Then you should check whether the proxy works by means of a special program or an online service providing such services. The next step is to configure the type of browser you are going to use. The procedure of setting itself depends on the type of browser and does not take much time. After correctly entering the IP address, username and password of the proxy server, don't forget to save the changes you made.

A VPN server address is an IP address or domain name through which you access the Internet. All traffic will be redirected through it. And the address is specified by the user, you can get it directly from the VPN-service, which provides such a service.

Chromium does not support proxies in-house. There is a corresponding item in the menu, but clicking on it will open the regular proxy server settings in Windows or MacOS.

In Node.js, you can parse JSON using the built-in JSON object or the JSON.parse() method. Here's a simple example:

// JSON string
const jsonString = '{"name": "John", "age": 30, "city": "New York"}';

// Parse JSON using JSON.parse()
try {
  const jsonData = JSON.parse(jsonString);
  console.log('Parsed JSON:', jsonData);

  // Access individual properties
  console.log('Name:', jsonData.name);
  console.log('Age:', jsonData.age);
  console.log('City:', jsonData.city);
} catch (error) {
  console.error('Error parsing JSON:', error.message);
}

In this example:

• The jsonString contains a JSON-formatted string.
• JSON.parse() is used to parse the JSON string into a JavaScript object.
• The properties of the resulting object can be accessed just like any other JavaScript object.

If the JSON string is not valid, JSON.parse() will throw an error. To handle potential errors, it's a good practice to use a try...catch block.

If you have a JSON file and want to read and parse it in Node.js, you can use the fs (file system) module along with JSON.parse(). Here's an example:

const fs = require('fs');

// Read JSON file
fs.readFile('path/to/your/file.json', 'utf8', (err, data) => {
  if (err) {
    console.error('Error reading file:', err.message);
    return;
  }

  // Parse JSON data
  try {
    const jsonData = JSON.parse(data);
    console.log('Parsed JSON from file:', jsonData);
  } catch (error) {
    console.error('Error parsing JSON:', error.message);
  }
});

Replace 'path/to/your/file.json' with the actual path to your JSON file.

Remember to handle errors appropriately, especially when dealing with file I/O operations or parsing potentially malformed JSON data.

After authorization in Selenium, you can navigate to another page using the get() method. The following steps outline the process:

Here's an example using Python:

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

driver = webdriver.Chrome()
driver.get("https://www.example.com/login")

# Locate the username field, password field, and login button
username_field = driver.find_element(By.ID, "username")
password_field = driver.find_element(By.ID, "password")
login_button = driver.find_element(By.ID, "login-button")

# Input your username and password
username_field.send_keys("your_username")
password_field.send_keys("your_password")

# Click the login button
login_button.click()

# Wait for the page to load after authorization
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "post-login-button")))

# Navigate to another page
driver.get("https://www.example.com/new-page")

In this example, replace "https://www.example.com/login", "username", "password", "login-button", and "your_username", "your_password" with the actual values for the website you are working with. Also, replace "https://www.example.com/new-page" with the URL of the page you want to navigate to after authorization.

Note that the example uses explicit waits to wait for the page to load after authorization. This is a good practice to ensure that the next actions are performed only after the page is fully loaded.
