Foward Proxy

Qt primarily focuses on providing tools and libraries for GUI development, networking, and other application-level features. While it includes facilities for working with XML through classes like QXmlStreamReader and QXmlStreamWriter, these are more geared toward parsing XML rather than HTML.

For HTML parsing, especially when using XPath expressions, you might need to consider additional libraries or tools. One common choice is to use a third-party library like Gumbo or htmlcxx. These libraries are not part of the Qt framework, but they can be used alongside Qt to handle HTML parsing.

Here's a basic example using htmlcxx for HTML parsing:

#include 
#include 
#include 

int main(int argc, char *argv[]) {
    QCoreApplication a(argc, argv);

    std::string htmlData = "
Hello, world!
";

    htmlcxx::HTML::ParserDom parser;
    tree dom = parser.parseTree(htmlData);

    // Example XPath query
    std::string xpathExpression = "//p/span";
    std::vector::iterator> result;
    htmlcxx::XPath::NodeSet nodeSet;
    htmlcxx::XPath::Parser xpathParser;
    xpathParser.compile(xpathExpression.c_str(), &nodeSet);

    for (tree::iterator it = dom.begin(); it != dom.end(); ++it) {
        nodeSet.evaluate(*it);
        if (nodeSet.size() > 0) {
            result.push_back(it);
        }
    }

    // Output the result
    for (auto &it : result) {
        std::cout << "Match found: " << htmlcxx::HTML::toPlainText(it->begin(), it->end()) << std::endl;
    }

    return a.exec();
}

In this example, I've used htmlcxx for HTML parsing and XPath queries. Note that you need to include the htmlcxx library in your project.

To scrape Binance courses data in Python, you can use web scraping libraries such as BeautifulSoup and requests. Here's an example using BeautifulSoup to scrape Binance courses

Install required libraries:

pip install beautifulsoup4 requests

Write the scraping code:

import requests
from bs4 import BeautifulSoup

def scrape_binance_courses():
    url = 'https://www.binance.com/en/academy/courses'

    # Send a GET request to the URL
    response = requests.get(url)

    # Check if the request was successful (status code 200)
    if response.status_code == 200:
        soup = BeautifulSoup(response.text, 'html.parser')

        # Find the container containing course information
        course_container = soup.find('div', {'class': 'css-7sfsgn'})

        if course_container:
            # Extract course details
            courses = course_container.find_all('div', {'class': 'css-1jiwjuo'})
            
            for course in courses:
                course_title = course.find('div', {'class': 'css-1mg41yd'}).text
                course_description = course.find('div', {'class': 'css-1q62c8m'}).text

                print(f"Title: {course_title}\nDescription: {course_description}\n")

        else:
            print("Course container not found.")
    else:
        print(f"Failed to retrieve the webpage. Status code: {response.status_code}")

# Run the scraping function
scrape_binance_courses()

This example sends a GET request to the Binance Academy courses page, parses the HTML content using BeautifulSoup, and extracts course details such as title and description.

Run the code:

python your_script_name.py

Setting up a proxy on your TV depends on the type of TV and the operating system it uses. Some smart TVs run on platforms like Android TV, webOS, or Tizen, which allow you to install apps and configure network settings. Here, I will provide instructions for popular smart TV platforms:

Android TV:
- Press the "Home" button on your remote control.
- Scroll up or down to "Apps" and highlight "Settings."
- Select "Network" or "Network & Internet."
- Choose "Advanced settings" or "More settings."
- Select "Manage proxy settings" or "Proxy settings."
- Choose "Enable proxy" and enter the proxy server address, port, and authentication credentials (if required).
- Save the settings and restart your TV if necessary.

webOS (LG Smart TV):
- Press the "Home" button on your remote control.
- Scroll up or down to "Settings" and select it.
- Choose "All Settings" or "General."
- Select "Network" or "Internet."
- Choose "Wi-Fi Direct" or "Wired" depending on your connection type.
- Select "Advanced settings" or "Internet settings."
- Choose "Manual proxy settings" and enter the proxy server address, port, and authentication credentials (if required).
- Save the settings and restart your TV if necessary.

Tizen (Samsung Smart TV):
- Press the "Menu" button on your remote control.
- Scroll up or down to "Settings" and select it.
- Choose "General" or "Network."
- Select "Network status" or "Internet."
- Choose "Wi-Fi" or "Wired" depending on your connection type.
- Select "Advanced settings" or "Internet settings."
- Choose "Manual proxy settings" and enter the proxy server address, port, and authentication credentials (if required).
- Save the settings and restart your TV if necessary.

In simple terms, it is a logically separated part of the main local or public network. It is through it that many users can use a proxy through a single server at the same time. Each connection is allocated to a separate subnet.

Proxies in Instagram are most often used for two purposes. The first is to bypass access blocking. The second is to avoid being banned when working with several accounts at once. The latter, as a rule, is used when arbitrating traffic, when launching massive advertising campaigns, which allows you not to worry about possibly getting a permanent ban.
