Libcurl Proxy

To check a proxy for blacklisting, it is necessary to use special tools developed for this purpose. Many proxy-checkers provide free online IP-address verification and provide detailed information related to the proxy servers security. To get it, just enter the IP address of the proxy and click on the "Verify" button.

When scraping dates from a website using Java, the SimpleDateFormat class is commonly used for parsing and formatting dates. Below is an example demonstrating how to scrape dates from a webpage and parse them using SimpleDateFormat. Additionally, you can use a library like Jsoup for HTML parsing.

Make sure to replace the URL, HTML parsing logic, and date format patterns with your specific requirements.

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import java.io.IOException;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class DateScrapingExample {

    public static void main(String[] args) {
        String url = "https://example.com"; // Replace with the URL of the webpage containing dates

        try {
            // Fetch HTML content using Jsoup
            Document document = Jsoup.connect(url).get();

            // Replace the following logic with the actual HTML parsing logic for dates
            Element dateElement = document.selectFirst(".date-selector"); // Replace with the appropriate selector
            String dateString = dateElement.text(); // Get the text content of the element

            // Parse the date using SimpleDateFormat
            SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            Date parsedDate = inputFormat.parse(dateString);

            // Format the date for display
            SimpleDateFormat outputFormat = new SimpleDateFormat("EEE, MMM d, yyyy 'at' h:mm a");
            String formattedDate = outputFormat.format(parsedDate);

            // Print the formatted date
            System.out.println("Scraped Date: " + formattedDate);
        } catch (IOException | ParseException e) {
            e.printStackTrace();
        }
    }
}

In this example:

• We use the Jsoup library to fetch the HTML content from the specified URL.
• We assume there is an HTML element with a class name of "date-selector" containing the date text. Adjust the selector based on the structure of the webpage you are scraping.
• The SimpleDateFormat class is used to parse the scraped date string into a Date object using the specified input format.
• Another SimpleDateFormat is used to format the date into a more readable output format.

Note: Make sure to handle exceptions appropriately, and adjust the date format patterns according to the actual format used on the webpage.

If your proxy is not connecting, there could be several reasons for the issue. Here are some steps you can take to troubleshoot and resolve the problem:

1. Check the proxy settings: Ensure that you have entered the correct proxy server address, port, and authentication credentials (if required) in your browser or application settings. Double-check for any typos or errors in the information.

2. Verify the proxy server status: Confirm that the proxy server is up and running. If you are using a third-party proxy service, check their website or contact their support for any ongoing issues or outages.

3. Test the internet connection: Disable the proxy settings and try connecting to the internet directly. If you can connect without the proxy, the issue might be with the proxy server itself.

4. Check for firewall or antivirus interference: Ensure that your firewall or antivirus software is not blocking the proxy connection. You may need to add an exception for the proxy server in your firewall or antivirus settings.

5. Update your browser or application: Make sure you are using the latest version of your browser or application, as older versions might have compatibility issues with the proxy server.

6. Clear browser cache and cookies: Sometimes, corrupted cache or cookies can cause issues with proxy connections. Try clearing your browser cache and cookies, then restart the browser and try connecting again.

7. Try a different proxy server: If the issue persists, consider using a different proxy server. You can find various proxy servers online, but be cautious when using free proxies, as they might be slow, unreliable, or insecure.

8. Consult support resources: If you are still unable to connect to the proxy server, consult the support resources or documentation for your browser or application. You can also reach out to the proxy server provider's support team for assistance.

Free proxies, while seemingly profitable and attractive, are actually not very effective. They cannot boast of security, speed, stability and acceptable duration of work. Qualitative and reliable proxies require a certain investment, but they can be obtained from companies that have a good reputation as proxy service providers. You can also find out about all the nuances of proxy selection with the help of special proxy databases.

One way to bypass parsing protection is to use a proxy server. After all, collecting information is most often done through special software. And it can be automatically blocked. But not when a proxy or VPN is used.
