Soft Proxy

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.

The OSError error in Python when using Selenium typically occurs when the WebDriver cannot find the specified executable or there's an issue with the executable itself. To resolve this issue, follow these steps:

Verify the WebDriver executable:

Make sure you have the correct WebDriver executable (e.g., chromedriver, geckodriver, edgedriver) for the browser you're using. Download the appropriate WebDriver from the following links:

Chrome: https://sites.google.com/a/chromium.org/chromedriver/downloads

Firefox: https://github.com/mozilla/geckodriver/releases

Edge: https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/

Set the path to the WebDriver executable:

In your Python script, set the path to the WebDriver executable using webdriver.Chrome(executable_path='path/to/chromedriver') or a similar method for other browsers. Replace 'path/to/chromedriver' with the actual path to your WebDriver executable.

Example:

from selenium import webdriver

driver = webdriver.Chrome(executable_path='path/to/chromedriver')

Check for typos or incorrect paths:

Ensure that the path to the WebDriver executable is correct and there are no typos in the file name or directory path.

Verify the WebDriver executable version:

Make sure the version of the WebDriver executable is compatible with the version of the browser you're using. For example, if you're using Chrome version 99.0.4844.51, you should download ChromeDriver version 99.0.4844.51 or higher.

Check for multiple WebDriver executables:

If you have multiple WebDriver executables installed, there might be a conflict. Make sure you're using the correct one in your script.

Update Selenium and WebDriver:

Sometimes, an outdated version of Selenium or the WebDriver executable can cause issues. Update Selenium and the WebDriver to the latest versions to avoid compatibility problems.

If you've tried all these steps and the issue persists, consider providing more information about the error message and the context in which it occurs. This will help in diagnosing the problem more accurately.

In Selenium with Python, you can set the name of the downloaded file by using the set_preference() method on the Options object before initializing the WebDriver. Here's an example using Chrome:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

# 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

# Close the browser
driver.quit()

Replace path/to/chromedriver, path/to/download/folder, and %f - %r with the appropriate values for your setup. The %f placeholder is replaced by the file name, and the %r placeholder is replaced by the original file name.

This example sets the download directory and the filename template for downloaded files. When a file is downloaded, it will be saved with a name that includes the original file name and a unique identifier, separated by a dash.

Keep in mind that this approach sets the download preferences for the entire browser session. If you need to change the download preferences for a specific test, you can set them before the test runs and reset them afterward.

Both versions of the protocol, at first glance, are able to provide anonymity on the Internet, as well as bypass all kinds of blockages. In addition, they are not only suitable for online entertainment, but also for work (study). This is what unites them to some extent, but there are still more differences. These are primarily the number of IP addresses, the cost of rent, appearance, connection speed, ping, and security. The IPv4 protocol, developed in the 1980s, is a more outdated model with a number of significant problems, including inefficient routing.

In Windows 8 and later editions it is recommended to setup network proxy through Group Policy. To do this, run GPMC.msc (via "Run" or enter in the "Search"), then select the section with the users, from the list of parameters select "Internet Settings". Further settings are not different from the standard ones in Windows. You can set proxy, specify the start page, enter restrictions and so on.
