Ambari Server Proxy

To implement a constant scraping process, you can use a combination of a loop and a delay to periodically scrape data from a website. This process is often referred to as "web scraping with intervals" or "periodic scraping." Here's an example using Node.js and the axios library for making HTTP requests

Install Dependencies

Install the required npm packages:

npm install axios

Write the Scraping Script

Create a Node.js script (e.g., constant_scraping.js) with the following code:

const axios = require('axios');

async function scrapeData() {
    try {
        // Replace with your scraping logic
        const response = await axios.get('https://example.com'); // Replace with the URL you want to scrape
        console.log('Scraped data:', response.data);

        // Add additional scraping logic as needed
        // ...

    } catch (error) {
        console.error('Error during scraping:', error.message);
    }
}

// Function to perform constant scraping with a specified interval
async function constantScraping(interval) {
    while (true) {
        await scrapeData();
        await sleep(interval); // Sleep for the specified interval before the next scrape
    }
}

// Function to introduce a delay using setTimeout
function sleep(ms) {
    return new Promise(resolve => setTimeout(resolve, ms));
}

// Set the interval (in milliseconds) for constant scraping
const scrapingInterval = 60000; // 60 seconds

// Start the constant scraping process
constantScraping(scrapingInterval);

Replace 'https://example.com' with the URL you want to scrape.

Adjust the scraping logic within the scrapeData function to meet your specific requirements.

Run the Script:

Run the script using Node.js:

node constant_scraping.js

This script defines a constantScraping function that continuously calls the scrapeData function at a specified interval using a loop and the sleep function. Adjust the interval (scrapingInterval) based on your scraping needs.

To change the proxy settings on an Android device, follow these steps:

1. Open the "Settings" app on your Android device.

2. Scroll down and tap on "Network & Internet" or "Connections," depending on your device's Android version and manufacturer.

3. Tap on "Wi-Fi" if you want to change the proxy settings for Wi-Fi connections, or "Mobile networks" if you want to change the proxy settings for cellular data.

4. If you're changing the settings for Wi-Fi, tap on the Wi-Fi network you're currently connected to. If you're changing the settings for mobile networks, tap on "Advanced options" or "Access Point Names (APN)."

5. Look for the "Proxy" or "Access Point" section. Tap on it to access the proxy settings.

6. You will see options to enter the proxy server's IP address and port number. Enter the required information for the proxy server you want to use. Some proxy servers may also require you to enter a username and password.

7. Once you've entered the proxy server details, save your changes by tapping on the "Save" or "Apply" button.

This is a proxy server integrated into the app to redirect traffic. It allows you to protect yourself from being tracked or to use the program where it is blocked. For example, at one time, users used a proxy server to bypass Telegram blocking.

The first thing you need to do to use a proxy in your browser is to make the necessary settings. In Google Chrome browser, go to "Network" and then find and click on "Change proxy settings". In the "Internet properties" window that opens, go to "Connection" and click on the "Network settings" button at the bottom. When a new window opens, check the "Use proxy server for local connections" box and the "Do not use proxy server for local addresses" box. Enter the proxy port and IP address in the corresponding fields, close the window and click "OK".

Rotary proxies are proxies that cyclically change their real IP address. This is used to make it harder to track their location. The port usually changes as well. How this happens depends on the software used on the proxy server.
