Combining Selenium with a Telegram Bot allows you to create an automated system that can interact with web pages and send updates to a Telegram chat. To achieve this, you'll need to follow these steps:

Create a Telegram Bot and get the API token.

Set up a Telegram Bot using the API token.

Use Selenium to interact with the web pages.

Send updates from the Selenium script to the Telegram Bot.

Here's a step-by-step guide:

Create a Telegram Bot and get the API token:

- Start a new chat with the BotFather (@BotFather) on Telegram.

- Send the command /newbot and follow the instructions to create a new bot.

- Note down the bot's username (e.g., YourBotName).

- Send the command /setname YourBotName to set the bot's name.

- Send the command /token to receive the API token. Save the API token securely.

Set up a Telegram Bot using the API token:

- Install a Telegram bot library, such as python-telegram-bot: pip install python-telegram-bot.

- Create a new Python script and import the required libraries:

from telegram.ext import Updater, CommandHandler, MessageHandler, Filters
import logging

logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s', level=logging.INFO)

Set up the Telegram Bot with the API token:

API_TOKEN = "your_telegram_bot_api_token"
updater = Updater(API_TOKEN, use_context=True)
dispatcher = updater.dispatcher

Create a function to handle incoming messages:

def echo(update, context):
    context.bot.send_message(chat_id=update.effective_chat.id, text=update.message.text)

Add a command handler and message handler to the dispatcher:

start_cmd = CommandHandler('start', echo)
dispatcher.add_handler(start_cmd)

message_handler = MessageHandler(Filters.text & ~Filters.command, echo)
dispatcher.add_handler(message_handler)

Start the bot:

updater.start_polling()
updater.idle()

Use Selenium to interact with the web pages:

Create a Selenium script to interact with the web pages as needed. For example, you can use the script to scrape data, log in to a website, or perform other actions.

Send updates from the Selenium script to the Telegram Bot:

Modify the echo function in the Telegram Bot script to accept data from the Selenium script and send it as an update. You can pass the data as a string or use other formats like JSON.

Here's an example of sending data as a string:

def echo(update, context):
    data = context.bot.send_message(chat_id=update.effective_chat.id, text="Received data:")
    context.bot.send_message(chat_id=update.effective_chat.id, text=data)

And here's an example of sending data as JSON:

import json

def echo(update, context):
    data = context.bot.send_message(chat_id=update.effective_chat.id, text="Received data:")
    data_json = json.dumps(data)
    context.bot.send_message(chat_id=update.effective_chat.id, text=data_json)

Now, when you run both the Selenium script and the Telegram Bot script simultaneously, the bot will receive updates with the data from the Selenium script and send it to the chat.

Remember to replace "your_telegram_bot_api_token" with your actual API token. Also, ensure that the bot has the necessary permissions to send messages in the chat where you want to receive updates.

Connecting to a Selenium Hub via a corporate proxy can be challenging, as the proxy may require authentication or have specific settings that need to be configured. To connect to the Selenium Hub through a corporate proxy, you'll need to configure the proxy settings in your Selenium client and Hub.

Here's a step-by-step guide on how to set up a Selenium Hub and client with corporate proxy settings:

Configure the Selenium Hub:

First, you need to configure the Selenium Hub to use the corporate proxy. You can do this by modifying the Hub's configuration file (usually hub.yml or hub.json) and adding the proxy settings.

For example, if you're using the hub.yml file, add the following configuration:

proxy:
  type: http
  httpProxy: http://username:[email protected]:port
  nonProxyHosts: localhost, 127.0.0.1, .example.com

Replace username, password, proxy.example.com, and port with the appropriate values for your corporate proxy. The nonProxyHosts setting specifies a list of hosts that should not use the proxy.

Configure the Selenium client:

Next, configure the Selenium client to use the corporate proxy. You can do this by setting the proxy settings in your WebDriver configuration.

For example, in Python with the Chrome WebDriver, you can configure the proxy as follows:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.proxy import Proxy, ProxyType

proxy = Proxy()
proxy.proxy_type = ProxyType.MANUAL
proxy.http_proxy = "http://username:[email protected]:port"
proxy.ssl_proxy = "http://username:[email protected]:port"

chrome_options = Options()
chrome_options.add_argument("--proxy-server=%s" % proxy.proxy)

driver = webdriver.Chrome(options=chrome_options)
driver.get('your_url')

# Rest of your code

driver.quit()

Replace username, password, proxy.example.com, and port with the appropriate values for your corporate proxy.

Start the Selenium Hub and connect the client:

Start the Selenium Hub and connect the client to the Hub using the appropriate configuration settings.

For example, if you're using the hub.yml file, start the Hub with the following command:

selenium-server-standalone jar hub.yml

Connect the client to the Hub using the appropriate configuration settings. For example, in Python, you can connect the client to the Hub as follows:

from selenium import webdriver
from selenium.webdriver.remote.webdriver import WebDriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

desired_caps = DesiredCapabilities.CHROME
desired_caps['proxy'] = {
    'httpProxy': 'http://username:[email protected]:port',
    'ftpProxy': 'http://username:[email protected]:port',
}

driver = WebDriver(desired_caps=desired_caps)
driver.get('your_url')

# Rest of your code

driver.quit()

Replace username, password, proxy.example.com, and port with the appropriate values for your corporate proxy.

By following these steps, you should be able to connect to a Selenium Hub via a corporate proxy and use the Selenium client to interact with webpages.

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.

The main task is to monitor traffic on the local network, as all requests will be handled by an organized proxy. Most often it is used to block access to certain resources in offices.

Go through the "Control Panel" to the "Browser Properties" section. Open the "Connections" tab, and then by clicking on the "Network settings" button at the bottom, uncheck the "Proxy server" box. Also uncheck the "Auto-detection" checkbox under "Auto-configuration".
