WVU Proxy

To check the quality of a proxy server, you can use one of the proxy checkers. There are a lot of them on the Internet. For example, hidemy.name. On the page of the checker you need to specify the IP-address and port of the required proxy server.

Proper parsing in C# often involves using libraries that provide robust and efficient parsing capabilities. Here are examples of parsing different types of data using standard C# libraries and techniques:

Parsing JSON with Newtonsoft.Json:

Ensure you have the Newtonsoft.Json NuGet package installed.

using Newtonsoft.Json;

// Example JSON string
string jsonString = "{\"name\": \"John\", \"age\": 25}";

// Deserialize JSON string to an object
var person = JsonConvert.DeserializeObject(jsonString);

// Define the corresponding C# class
public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

Parsing XML with System.Xml:

using System.Xml.Linq;

// Example XML string
string xmlString = "John25";

// Parse XML string
var xmlElement = XElement.Parse(xmlString);

// Access XML elements and attributes
string name = xmlElement.Element("name").Value;
int age = int.Parse(xmlElement.Element("age").Value);

Parsing DateTime from a String:

// Example date string
string dateString = "2022-01-01";

// Parse string to DateTime
DateTime parsedDate;
if (DateTime.TryParse(dateString, out parsedDate))
{
    // Use parsedDate
    Console.WriteLine(parsedDate.ToString("yyyy-MM-dd"));
}
else
{
    Console.WriteLine("Invalid date format");
}

Parsing Integers from a String:

// Example integer string
string numberString = "123";

// Parse string to integer
if (int.TryParse(numberString, out int parsedNumber))
{
    // Use parsedNumber
    Console.WriteLine(parsedNumber);
}
else
{
    Console.WriteLine("Invalid integer format");
}

Parsing CSV Data:

You can use the TextFieldParser class from the Microsoft.VisualBasic.FileIO namespace.

using Microsoft.VisualBasic.FileIO;
using System.IO;

// Example CSV file path
string csvFilePath = "example.csv";

// Parse CSV file
using (TextFieldParser parser = new TextFieldParser(csvFilePath))
{
    parser.TextFieldType = FieldType.Delimited;
    parser.SetDelimiters(",");

    while (!parser.EndOfData)
    {
        // Read current line
        string[] fields = parser.ReadFields();

        // Process fields
        foreach (string field in fields)
        {
            Console.Write(field + " ");
        }
        Console.WriteLine();
    }
}

Always handle exceptions appropriately when parsing, especially when dealing with user input or data from external sources.

To simulate a click during scraping, you can use a headless browser automation library like Puppeteer for Node.js. Puppeteer provides a high-level API to control headless browsers, allowing you to automate tasks such as clicking on elements, filling out forms, and navigating through pages.

Here's a basic example of how you can use Puppeteer to simulate a click:

1. Install Puppeteer:

   • Install Puppeteer using npm:

npm install puppeteer

Write the Scraping Script:

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

const puppeteer = require('puppeteer');

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

    try {
        // Navigate to the target URL
        await page.goto('https://example.com');

        // Wait for a specific selector to appear (replace with the selector of the element you want to click)
        const elementSelector = 'button#exampleButton';
        await page.waitForSelector(elementSelector);

        // Simulate a click on the specified element
        await page.click(elementSelector);

        // Wait for the page to settle (replace with additional logic if needed)
        await page.waitForTimeout(2000);

        // Extract and print information after the click
        const extractedInfo = await page.evaluate(() => {
            // Replace this with your logic to extract information from the clicked page
            return document.title;
        });

        console.log('Extracted information after click:', extractedInfo);
    } catch (error) {
        console.error('Error during scraping:', error);
    } finally {
        // Close the browser
        await browser.close();
    }
}

// Run the scraping script
scrapeWithClick();

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

  • Replace 'button#exampleButton' with the selector of the element you want to click.

• Run the Script:

  • Run the script using Node.js:

node scrape_with_click.js

This script uses Puppeteer to launch a headless browser, navigate to a specified URL, wait for a specific element to appear, simulate a click on that element, and then perform additional actions or extractions as needed.

Make sure to handle errors and adjust the script based on the structure of the website you are scraping.

There are special online services that use IP and HTTP connection tags to determine if a proxy is being used from your equipment. The most popular are Proxy Checker, Socproxy.

In the "Settings" of any Android smartphone there is a "VPN" item. And there you can manually specify the parameters of the proxy, through which the connection to the Internet will be made. There, some of the programs also import ready-made scripts for proxy connections.
