Torrent Proxy Server

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 doesn't see the driver from Selenium.WebDriver.ChromeDriver, it could be due to a few reasons. Here are some steps to troubleshoot and resolve the issue:

Check the ChromeDriver version:

Make sure you're using the correct version of ChromeDriver that matches the version of the Chrome browser installed on your system. You can download the appropriate version of ChromeDriver from here.

Update the ChromeDriver path:

Ensure that the path to the ChromeDriver executable is correctly specified in your code. If you're using the ChromeOptions class to set the path, make sure you're using the correct property name. For example, in C#, use the ExecutablePath property:

ChromeOptions options = new ChromeOptions();
options.AddArgument("--headless");
options.ExecutablePath = @"C:\path\to\chromedriver.exe";

using (ChromeDriver driver = new ChromeDriver(options))
{
    driver.Navigate().GoToUrl("your_url");
    // Rest of your code
}

Replace C:\path\to\chromedriver.exe with the actual path to the ChromeDriver executable on your system.

1. Check for multiple ChromeDriver versions:

Sometimes, having multiple versions of ChromeDriver installed on your system can cause issues. Make sure there are no conflicting versions of ChromeDriver on your system and that the correct version is being used.

2. Check for antivirus or security software interference:

Sometimes, antivirus or security software can interfere with the execution of ChromeDriver. Try temporarily disabling your antivirus or security software to see if it resolves the issue. If it does, you may need to add an exception for ChromeDriver or change your antivirus settings.

3. Check the console output:

Examine the console output for any error messages or warnings that might provide more information about the issue. This can help you identify the root cause of the problem and find a suitable solution.

If you've tried all these steps and are still encountering issues, please provide more information about your system, including the operating system, Chrome browser version, and the specific error message or problem you're facing. This will help diagnose the issue further and find a suitable solution.

To keep only unique external links while scraping with Scrapy, you can use a set to track the visited external links and filter out duplicates. Here's an example spider that demonstrates how to achieve this:

import scrapy
from urllib.parse import urlparse, urljoin

class UniqueLinksSpider(scrapy.Spider):
    name = 'unique_links'
    start_urls = ['http://example.com']  # Replace with the starting URL of your choice
    visited_external_links = set()

    def parse(self, response):
        # Extract all links from the current page
        all_links = response.css('a::attr(href)').extract()

        for link in all_links:
            full_url = urljoin(response.url, link)

            # Check if the link is external
            if urlparse(full_url).netloc != urlparse(response.url).netloc:
                # Check if it's a unique external link
                if full_url not in self.visited_external_links:
                    # Add the link to the set of visited external links
                    self.visited_external_links.add(full_url)

                    # Yield the link or process it further
                    yield {
                        'external_link': full_url
                    }

        # Follow links to other pages
        for next_page_url in response.css('a::attr(href)').extract():
            yield scrapy.Request(url=urljoin(response.url, next_page_url), callback=self.parse)

- visited_external_links is a class variable that keeps track of the unique external links across all instances of the spider.
- The parse method extracts all links from the current page.
- For each link, it checks if it is an external link by comparing the netloc (domain) of the current page and the link.
- If the link is external, it checks if it is unique by looking at the visited_external_links set.
- If the link is unique, it is added to the set, and the spider yields the link or processes it further.
- The spider then follows links to other pages, recursively calling the parse method.

Remember to replace the start_urls with the URL from which you want to start scraping.

For Telegram, it is recommended to use paid proxy servers of the Socks5 protocol. These proxies provide the user with data protection and high and stable connection speed. Telegram developers recommend using servers from European countries.

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).
