Nginx Proxy Certbot

Open the "Start" menu and type "Browser Properties" in the search box. Then, go to the "Connection" tab, click on "Network settings" and disable the use of the proxy server. Reboot Windows and check if your Internet connection works. If the problem persists, open the "Advanced" tab in the "Browser Properties" window and check the box next to "Delete personal settings", click "Reset" and restart your computer.

Proxy servers are of the following types:
FTP proxy designed to send data to FTP servers.
CGI proxy, which is used to browse web services in a browser. You do not need to configure any settings. All actions are performed anonymously. Often such proxies are designed in the form of a page where you have to specify the address of a desired site.
SMTP, POP3 and IMAP proxy are designed for sending and receiving email.
HTTP and HTTPS proxies are for scrolling web services.
Socks proxy are used as an anonymizer. No one will know about the user's actions.

Flipping a page (or navigating to the next/previous page) using Selenium involves interacting with the browser's navigation controls. You can use the WebDriver methods provided by Selenium to navigate between pages. Here are examples in Python using Selenium

1. Navigate to the Next Page:

from selenium import webdriver

# Create a WebDriver instance (e.g., Chrome)
driver = webdriver.Chrome()

# Navigate to the initial page
driver.get("https://example.com/page1")

# Perform actions on the first page...

# Navigate to the next page
driver.find_element_by_link_text("Next").click()  # Replace with the actual locator for the "Next" link

# Perform actions on the second page...

# Close the browser when done
driver.quit()

2. Navigate to the Previous Page:

from selenium import webdriver

# Create a WebDriver instance (e.g., Chrome)
driver = webdriver.Chrome()

# Navigate to the second page
driver.get("https://example.com/page2")

# Perform actions on the second page...

# Navigate to the previous page
driver.back()

# Perform actions on the first page...

# Close the browser when done
driver.quit()

3. Navigate to a Specific Page:

from selenium import webdriver

# Create a WebDriver instance (e.g., Chrome)
driver = webdriver.Chrome()

# Navigate to a specific page
driver.get("https://example.com/page3")

# Perform actions on the third page...

# Close the browser when done
driver.quit()

Replace the placeholder URLs and locators with the actual URLs and locators for your specific use case. The click() method is used to simulate clicking on a link or button that leads to the next page.

If you're navigating between pages that are part of a sequence (e.g., Next/Previous buttons), locate the appropriate elements using Selenium's methods (find_element_by_id, find_element_by_xpath, find_element_by_link_text, etc.) and perform the necessary actions.

Remember that the order of actions in your script should match the sequence of interactions on the pages you are navigating. Also, consider using explicit waits (WebDriverWait) to ensure that the elements on the new page are fully loaded before interacting with them.

To pass a variable from Python to Selenium JavaScript, you can use the execute_script method provided by the WebDriver instance. This method allows you to execute custom JavaScript code within the context of the current web page. You can pass Python variables as arguments to the JavaScript code.

Here's an example using Python:

Install the required package:

pip install selenium

Create a method to execute JavaScript with a Python variable:

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 execute_javascript_with_python_variable(driver, locator, python_variable):
    element = WebDriverWait(driver, 10).until(EC.visibility_of_element_located(locator))
    return driver.execute_script("return arguments[0] + arguments[1];", element.text + python_variable)

Use the execute_javascript_with_python_variable 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 element you want to interact with
locator = (By.ID, "element-id")

# Execute JavaScript with a Python variable
result = execute_javascript_with_python_variable(driver, locator, "Hello, World!")

# Print the result
print(result)

# Perform any additional actions as needed

# Close the browser
driver.quit()

In this example, we first create a method called execute_javascript_with_python_variable that takes a driver instance, a locator tuple containing the locator strategy and locator value, and a python_variable string containing the Python variable value. Inside the method, we use the WebDriverWait class to wait for the element to become visible and then call the execute_script method with the JavaScript code that concatenates the element's text and the Python variable.

In the test code, we set up the WebDriver, navigate to the target web page, and locate the element using the locator variable. We then call the execute_javascript_with_python_variable method with the driver, locator, and "Hello, World!" as input. The method returns the concatenated result, which we print in the console.

Remember to replace "https://www.example.com", "element-id", and "Hello, World!" with the actual URL, element ID or locator, and desired Python variable value.

A proxy server spoofs the IP address, port, and hardware information. It can also act as a secure gateway for data transmission in an already encrypted form (for example, this is how a proxy with the SOCKS5 protocol works).
