Proxy Viettel

A reverse proxy is mainly used by administrators and is responsible for balancing workload and high availability. The reverse proxy redirects received requests to one of its web servers. From the outside it is completely invisible and looks as if all required resources are concentrated directly in the proxy.

When using Selenium for automation, it's important to be aware that websites can detect automation and may have measures in place to identify bot-like behavior. Some websites employ techniques to detect whether a user is interacting with the site through a web browser or through automated scripts like Selenium.

While it's not recommended to hide the fact that you are using Selenium, there are strategies you can employ to make your automation less detectable. Keep in mind that attempting to hide automation might violate the terms of service of certain websites, and it's important to respect the policies of the websites you are interacting with.

Here are some strategies to make your Selenium automation less detectable

1. Use Headless Mode

Running the browser in headless mode means it operates without a graphical user interface. This can make your automation less conspicuous. However, be aware that some websites can still detect headless browsers.

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument('--headless')

driver = webdriver.Chrome(options=options)

2. Modify User Agent

Change the user agent to simulate different browsers or devices. This can make your requests look more like those coming from real users.

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument('--user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36')

driver = webdriver.Chrome(options=options)

3. Slow Down Interactions

Introduce delays between your interactions to mimic more human-like behavior. Websites might detect automation based on rapid, sequential requests.

import time

# Introduce a delay
time.sleep(2)

4. Randomize Interactions

Add randomization to your script, such as randomizing wait times, order of interactions, or the number of interactions. This can make your script less predictable.

import random

# Randomize wait time
time.sleep(random.uniform(1, 3))

5. Handle Cookies and Sessions

Manage cookies and sessions effectively to simulate real user behavior. Log in, handle sessions, and manage cookies as a real user would.

6. Avoid Common Automation Detection Techniques

Be aware of common techniques websites use to detect automation, such as checking for the presence of WebDriver properties. You may need to work around these checks or use techniques to override them.

Please note that while these strategies may make your Selenium automation less detectable, they may not guarantee complete invisibility. Websites can employ sophisticated methods to detect automation, and attempting to bypass detection mechanisms might violate the terms of service of the website.

To transfer requests session from Requests to Selenium, you can follow these steps:

First, import the necessary libraries:

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

Create a new requests session and perform your requests:

req_session = Session()
response = req_session.get('https://example.com')

Now, create a new Selenium WebDriver instance and pass the requests session as a parameter:

driver = webdriver.Chrome()
driver.get('https://example.com')
req_session_cookies = req_session.cookies.get_dict()
driver.add_cookies(list(req_session_cookies.values()))

Use Selenium to interact with the web page:

search_box = WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.ID, 'search-box')))
search_box.send_keys('your search query')
search_box.send_keys(Keys.RETURN)

To continue using the same session for subsequent requests, you can create a new requests session with the cookies from the Selenium driver:

selenium_session_cookies = driver.get_cookies()
new_req_session = Session()
for cookie in selenium_session_cookies:
    new_req_session.cookies.set(cookie['name'], cookie['value'])

Now you can use the new_req_session to make new requests while maintaining the same session as the Selenium driver.

Remember to close the Selenium driver after you're done:

driver.quit()

If PhantomJS doesn't find an element by XPATH, there are a few potential issues that could be causing the problem. Here are some steps you can take to troubleshoot and resolve the issue:

1. Check the XPATH: Make sure the XPATH you're using is correct and points to the right element on the page. You can use browser developer tools to inspect the element and obtain the correct XPATH.

2. Wait for the element to load: Sometimes, the element might not be loaded when the script tries to find it. In such cases, you can use the WebDriverWait class to wait for the element to be present before interacting with it.

Example:

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

driver = webdriver.PhantomJS()
driver.get("http://example.com")

wait = WebDriverWait(driver, 10)
element = wait.until(EC.presence_of_element_located((By.XPATH, "//your/xpath/here")))

3. Use different locator strategies: If the XPATH is correct but still not working, try using other locator strategies like ID, NAME, or CSS_SELECTOR to locate the element.

4. Update PhantomJS: Make sure you are using the latest version of PhantomJS. Older versions might have issues with certain web pages or elements.

5. Check for JavaScript errors: PhantomJS might not be able to find the element if there are JavaScript errors on the page. Open the page in a regular browser and check for any errors in the console.

6. Use a different headless browser: If PhantomJS continues to give you trouble, consider using a different headless browser like Headless Chrome or Headless Firefox. These browsers are more up-to-date and have better support for modern web technologies.

Remember to replace "//your/xpath/here" with the actual XPATH you are trying to use, and ensure that the XPATH points to the correct element on the page.

There are several options for its use: bypassing the blocking of websites, shopping in foreign online stores at regional (local) prices, access to a full library of media content, hiding your real IP-address.
