Deckstats Proxy

The reason for the lack of connection to the network can be due to incorrect proxy settings, that is, incorrect IP addresses were entered or specified, or the server simply does not work. Users also often forget that proxy settings must be disabled.

If Selenium is returning a blank page when you query it, there could be several reasons for this issue. Here are some common causes and solutions:

1. Timing Issues

Selenium might be trying to interact with the page before it has fully loaded. Ensure that you use explicit waits (WebDriverWait) to wait for the elements to be present, visible, or interactive before interacting with them.

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.Chrome()
driver.get("https://example.com")

# Wait for the page title to be present
WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.TAG_NAME, 'title')))

# Continue with your script...

2. Incorrect Locator or Query

Double-check your locators and queries to ensure that you are selecting the correct elements. Incorrect locators might lead to the selection of non-existent or hidden elements.

3. Browser Window Size

In headless mode or when the browser window is too small, elements might not be visible. Ensure that your script maximizes the browser window or sets an appropriate window size.

driver.maximize_window()

4. JavaScript Errors

Check the browser console for any JavaScript errors that might be affecting the page. Use console.log statements in JavaScript to debug if needed.

console.log("Debug message from JavaScript");

5. Network Issues

Network issues might prevent the page from loading completely. Ensure that your network connection is stable.

6. Browser Extensions

Certain browser extensions might interfere with Selenium. Disable extensions or use a clean browser profile for testing.

7. Headless Mode Issues

If you are running Selenium in headless mode, try running the script in non-headless mode to see if the issue persists. Some websites may behave differently in headless mode.

8. Check for Captchas or Security Measures

Some websites use captchas or additional security measures that could interfere with automated scripts. Ensure that your script is not encountering captchas.

9. Web Page Structure Changes

Web pages are dynamic, and changes in the structure of the page might affect your script. Inspect the HTML source code of the page to ensure that your locators are still valid.

10. Logging

Add logging statements to your script to output information at different stages. This can help in identifying where the issue might be occurring.

11. Browser Version Compatibility

Ensure that your Selenium WebDriver version is compatible with the browser version you are using. Update your WebDriver if necessary.

However, there are alternative approaches and bindings that allow you to use Selenium with C++. Here are a couple of options:

1. CppDriver:

   • CppDriver is a C++ implementation of the WebDriver protocol that allows you to interact with web browsers. It is not an official Selenium project but provides a way to use Selenium-like functionality in C++.

   GitHub Repository: CppDriver

   Keep in mind that the project may not be as actively maintained or feature-rich as official Selenium bindings for other languages.

2. WebDriver C++ Client Library (Unofficial):

   • There are unofficial C++ bindings or client libraries developed by the community. These libraries may provide a way to interact with WebDriver or Selenium-like functionality in C++. However, their usage and features may vary.

   GitHub Repository Example: webdriver-cpp

   Note: Unofficial bindings might not be as comprehensive or up-to-date as official Selenium bindings.

3. Use Selenium with C++ via External Libraries:

   • Another approach is to use C++ along with external libraries that can control browsers. For example, you might use C++ to control a headless browser like Chromium or automate interactions using browser automation libraries.

   Keep in mind that this approach may not provide the same level of abstraction and cross-browser compatibility as Selenium WebDriver.

Before choosing any of these options, carefully review the documentation, community support, and compatibility with your specific requirements. Since these projects are not officially supported by the Selenium project, they may have limitations and may not be as stable or feature-rich as Selenium WebDriver in other languages.

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.

A proxy is a service that allows access to websites blocked in different countries, while hiding your own IP address. It is a kind of intermediary between the end server and the owner's computer. A VPN provides an encrypted connection to the network, which not only allows you to keep your privacy, hide your IP address, encrypt Internet traffic, but also bypasses firewalls.
