Wild Proxies

To specify the data of a proxy server in the Opera browser, you need to follow the algorithm below:

Open the browser.
Click on the Opera icon in the upper left corner.
Go to "Settings".
Select the "Advanced" option.
Scroll down to the "System" tab.
Click "Open proxy settings for computer".
Click on "Network settings".
Activate the "Use a proxy server" option.
In the tab that opens, specify the IP address of the proxy server. The address must be entered in the field of the protocol to which the proxy server belongs. You can get this information from your proxy provider. Click "OK" to save your settings.

In AnyDesk, in order to ensure maximum security of transmitted traffic, you can use proxies, including encryption of traffic. The setting is made through the regular menu of the application. You will need to go to "Options", select "Connection", specify the proxy and port number. Connection is made automatically after that.

In Selenium with Python, you can add cookies to your browser session using the add_cookie method of the WebDriver's options or add_cookie method of the WebDriver instance. If you have cookies saved in a file, you can read the file and then add the cookies to your Selenium session. Here's an example:

from selenium import webdriver
import pickle

# Create a new instance of the browser (e.g., Chrome)
driver = webdriver.Chrome()

# Read cookies from a file (replace 'cookies.pkl' with your actual file name)
with open('cookies.pkl', 'rb') as cookies_file:
    cookies = pickle.load(cookies_file)

# Add each cookie to the browser session
for cookie in cookies:
    driver.add_cookie(cookie)

# Now the browser should have the added cookies

# Example: Navigate to a website after setting cookies
driver.get('https://example.com')

# Continue with your script...

# Close the browser when done
driver.quit()

In this example:

1. The Selenium WebDriver (Chrome in this case) is created.
2. Cookies are read from a file using the pickle module. Make sure your cookies file is in the correct format (a list of dictionaries).
3. Each cookie is added to the browser session using the add_cookie method.
4. The script navigates to a website (https://example.com) after setting the cookies. Adjust this part according to your specific use case.
5. The browser is closed using driver.quit() when the script is done.

Make sure to replace 'cookies.pkl' with the actual path to your cookies file.

Note: The format of the cookies file is crucial. It should be a list of dictionaries, and each dictionary should contain at least the keys 'name', 'value', 'domain', and 'path'. If the cookies were obtained using get_cookies() in a previous Selenium session, you can directly save the result using pickle.dump(cookies, file).

Here's a simple example of how to save cookies:

from selenium import webdriver
import pickle

driver = webdriver.Chrome()
driver.get('https://example.com')

# Get cookies
cookies = driver.get_cookies()

# Save cookies to a file
with open('cookies.pkl', 'wb') as cookies_file:
    pickle.dump(cookies, cookies_file)

driver.quit()

Then, you can use the first script to load and set these cookies in a new Selenium session.

If you can't download images in Scrapy:

- Check the image pipeline configuration in settings.py.
- Verify HTTPS compatibility and install the certifi package if necessary.
- Confirm the correctness of XPath or CSS selectors for image URLs.
- Ensure image URLs are in the correct format; log URLs for inspection.
- Handle redirects by setting REDIRECT_ENABLED = True.
- Check and set appropriate HTTP headers in your Scrapy spider.
- Adjust the CONCURRENT_REQUESTS setting to avoid server restrictions.
- Verify correct configuration of the ImagesPipeline.
- Inspect the downloaded images in the specified IMAGES_STORE directory.
- Implement exception handling in your spider to catch download errors.

A proxy in data centers is usually a separate server that processes incoming requests and then distributes them to the submitted addresses (or IP). Also through the proxy it is possible to allocate a specific user a separate IP address for connection (for example, if he needs a virtual server).
