Scraping a large number of web pages using JavaScript typically involves the use of a headless browser or a scraping library. Puppeteer is a popular headless browser library for Node.js that allows you to automate browser actions, including web scraping.

Here's a basic example using Puppeteer:

Install Puppeteer:

npm install puppeteer

Create a JavaScript script for web scraping:

const puppeteer = require('puppeteer');

async function scrapeWebPages() {
    const browser = await puppeteer.launch();
    const page = await browser.newPage();

    // Array of URLs to scrape
    const urls = ['https://example.com/page1', 'https://example.com/page2', /* add more URLs */];

    for (const url of urls) {
        await page.goto(url, { waitUntil: 'domcontentloaded' });

        // Perform scraping actions here
        const title = await page.title();
        console.log(`Title of ${url}: ${title}`);

        // You can extract other information as needed

        // Add a delay to avoid being blocked (customize the delay based on your needs)
        await page.waitForTimeout(1000);
    }

    await browser.close();
}

scrapeWebPages();

Run the script:

node your-script.js

In this example:

• Puppeteer is used to launch a headless browser and open pages.
• The urls array contains the list of web pages to scrape. You can extend this array with the URLs you need.
• Inside the loop, you can perform scraping actions using Puppeteer functions. For example, extracting data using page.title().

Keep in mind the following:

• Be aware of the legality and terms of service for web scraping on the targeted websites.
• Respect the websites' robots.txt files and use delays between requests to avoid being blocked.
• Customize the scraping logic based on the structure of the web pages you are dealing with.

In Qt, you can use the QUdpSocket class to handle incoming UDP packets and the QDataStream class to parse the QByteArray into a bitfield structure. Here's an example of how to accept and parse a UDP QByteArray into a bitfield structure in Qt:

1. First, create a structure to represent the bitfield:

struct Bitfield {
    unsigned int field1 : 8;
    unsigned int field2 : 8;
    unsigned int field3 : 8;
    unsigned int field4 : 8;
};

2. Next, create a QUdpSocket object and bind it to a specific port:

QUdpSocket udpSocket;
if (!udpSocket.bind(QHostAddress::Any, 12345)) {
    qDebug() << "Failed to bind UDP socket:" << udpSocket.errorString();
    return;
}

3. In the readyRead() slot, accept incoming UDP packets and parse the QByteArray:

void MyClass::handleIncomingDatagram() {
    QByteArray datagram = udpSocket.receiveDatagram();
    QDataStream dataStream(&datagram, QIODevice::ReadOnly);

    Bitfield bitfield;
    dataStream >> bitfield;

    // Process the bitfield structure as needed
    qDebug() << "Received bitfield:" << bitfield.field1 << "," << bitfield.field2 << "," << bitfield.field3 << "," << bitfield.field4;
}

4. Finally, connect the readyRead() signal to the handleIncomingDatagram() slot:

connect(&udpSocket, &QUdpSocket::readyRead, this, &MyClass::handleIncomingDatagram);

In this example, the handleIncomingDatagram() slot is called whenever a new UDP packet is received. The slot accepts the incoming datagram, parses it into a bitfield structure using QDataStream, and processes the bitfield as needed.

Make sure to include the necessary headers in your code:

#include 
#include 
#include 
#include 

This example assumes that the incoming UDP packet contains exactly 4 bytes, which is enough to store the bitfield structure. If the packet contains more data, you'll need to handle it accordingly.

To configure a proxy manually, you'll need to access the settings of the application or software you're using that requires a proxy server. The steps to configure a proxy manually will vary depending on the application or software. Here are some general steps for common applications:

For Web Browsers:

1. Open your web browser (e.g., Chrome, Firefox, Edge).
2. Click on the menu button (usually three horizontal lines or three dots) and select "Settings" or "Options."
3. Look for a section related to "Network settings," "Proxy settings," or "Connections."
4. In the proxy settings, you'll find fields for the proxy server address and port. Enter the proxy server address and port provided by your proxy service.
5. If your proxy server requires authentication, enter the username and password in the respective fields.
6. Save your changes and close the settings window.

For Windows:

1. Press the Windows key + R to open the Run dialog.
2. Type "inetcpl" and press Enter to open the Internet Properties window.
3. Go to the "Connections" tab, and click on "LAN settings."
4. In the LAN settings, check the box next to "Use a proxy server for your LAN" if you have a proxy server configured. Enter the proxy server address and port in the appropriate fields.
5. If your proxy server requires authentication, check the box next to "Bypass proxy server for local addresses" and enter the local IP address of the website you want to access (e.g., "127.0.0.1" for localhost).
6. Save your changes and close the Internet Properties window.

For macOS:

1. Click the Apple menu and select "System Preferences."
2. Click "Network."
3. Select the network connection you want to configure the proxy settings for (e.g., Wi-Fi, Ethernet).
4. Click the "Advanced" button.
5. Go to the "Proxies" tab.
6. Check the box next to "HTTP proxy" or "HTTPS proxy" if you have a proxy server configured. Enter the proxy server address and port in the appropriate fields. 7. If your proxy server requires authentication, click the "Security" tab and check the box next to "Proxy server is secure." Enter the username and password in the respective fields.
8. Save your changes and close the Network preferences window.

Connect your computer to a functioning router, then open any browser, go to the settings and enable manual configuration. Specify the IP, gateway with DNSI and subnet mask in the appropriate fields. In the "Home network" tab, under "Computers", go to "IPMP Proxy" and turn off this function. Under "System", click on the gear symbol, and under "Components", specify the Proxy UDP HTTP utility and click "Refresh".

If you are interested in a quality and fast proxy server, do not look for it among the free options. All of them, although they seem to be profitable, in fact do not differ in duration of work and speed. It is recommended to buy quality proxies from reputable proxy service providers that are widely available on the Internet.
