Thai Proxy Service

Most users use A-Parser for this purpose. It is one of the best applications for checking web applications. There is a corresponding tab, "Proxy server", in the standard menu of A-Parser. It is where you can specify the settings for the connection. And in the "Tools" section you can use parameters for parsing.

If you are parsing a site using JSoup in a Java application and you want to introduce a delay between requests to avoid being blocked or rate-limited by the website, you can use Thread.sleep to pause the execution for a specified duration. Here's a basic example

First, make sure you have the JSoup library included in your project. If you're using Maven, you can add the following dependency to your pom.xml:

    org.jsoup
    jsoup
    1.14.3 

Now, here's an example Java program using JSoup with a delay between requests:

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;

import java.io.IOException;

public class WebScraperWithDelay {

    public static void main(String[] args) {
        // Replace with the URL you want to scrape
        String url = "https://example.com";
        
        // Number of milliseconds to wait between requests
        long delayMillis = 2000; // 2 seconds
        
        try {
            for (int i = 0; i < 5; i++) {
                // Make the HTTP request using JSoup
                Document document = Jsoup.connect(url).get();

                // Process the document as needed
                System.out.println("Title: " + document.title());

                // Introduce a delay between requests
                Thread.sleep(delayMillis);
            }
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}

In this example:

1. Jsoup.connect(url).get() is used to make an HTTP request and retrieve the HTML document from the specified URL.
2. Thread.sleep(delayMillis) introduces a delay of 2 seconds between requests. You can adjust the value of delayMillis based on your needs.

You can use Selenium WebDriver to find out the URL of the active tab in the browser. Here's an example using Python with Selenium:

from selenium import webdriver

# Create a WebDriver instance (assuming Chrome in this example)
driver = webdriver.Chrome()

try:
    # Navigate to a website
    driver.get("https://www.example.com")

    # Get the URL of the active tab
    current_url = driver.current_url
    print("URL of the active tab:", current_url)

    # Perform other actions as needed

finally:
    # Close the browser window
    driver.quit()

In this example:

• driver.get("https://www.example.com") navigates to a specific website.
• driver.current_url retrieves the URL of the currently active tab.

Make sure to replace "https://www.example.com" with the actual URL you want to navigate to.

Keep in mind that this method retrieves the URL of the currently active tab. If you have multiple tabs open and you want to switch between them, you can use the driver.window_handles method to get a list of window handles and then switch to the desired window. For example:

# Open a new tab or window
driver.execute_script("window.open('about:blank', '_blank');")

# Switch to the newly opened tab
driver.switch_to.window(driver.window_handles[1])

# Get the URL of the active tab
new_tab_url = driver.current_url
print("URL of the new tab:", new_tab_url)

This code opens a new tab, switches to it, and then retrieves the URL of the new tab.

If PyCharm Community Edition (PyCharm CE) has stopped recognizing the Selenium package, it could be due to various reasons. Here are some steps you can take to troubleshoot and resolve the issue:

1. Check Virtual Environment:

   • If you are using a virtual environment, make sure it is activated in PyCharm. Virtual environments isolate project dependencies, and if the virtual environment is not activated, PyCharm may not recognize installed packages.

2. Reinstall Selenium:

   • Try reinstalling the Selenium package in your project. Open the terminal in PyCharm and run the following command:

pip uninstall selenium
pip install selenium

• PyCharm Cache:

  • Clear the PyCharm cache, as cached information might be causing the issue. You can find the "Invalidate Caches / Restart" option under the "File" menu in PyCharm.

• Project Interpreter:

  • Make sure that the correct Python interpreter is selected for your project. Go to "File" > "Settings" > "Project: YourProjectName" > "Python Interpreter" and ensure that the interpreter matches the one where Selenium is installed.

• Check for Typos and Case Sensitivity:

  • Ensure that your import statements and references to the Selenium package are correct. Python is case-sensitive, so selenium should be in lowercase.

from selenium import webdriver

6. Restart PyCharm:

   • Sometimes, restarting PyCharm can resolve issues related to package recognition.

7. Check for Python File Naming Conflicts:

   • Ensure that there are no conflicting file names in your project. Sometimes, naming a file with the same name as a module might lead to import issues.

8. Check for Project Integrity:

   • Open your project's root directory and check if there are any issues with the project structure or files.

9. Update PyCharm:

   • Ensure that you are using the latest version of PyCharm. If not, consider updating to the latest version.

10. External Factors:

    • Check if there are any external factors affecting the Python environment, such as antivirus software or security tools.

11. Check Project SDK:

    • Confirm that the project SDK is set correctly. Go to "File" > "Project Structure" > "Project" and ensure that the correct Python interpreter is selected.

12. Check for IDE-Specific Issues:

    • Check the PyCharm forums or support channels for any known issues related to Selenium recognition in the specific version of PyCharm you are using.

After trying these steps, you should be able to resolve the issue of PyCharm CE not recognizing the Selenium package. If the problem persists, additional details about error messages or symptoms would be helpful for further assistance.

If you can't download images in Scrapy:

- Check the image pipeline configuration in settings.py.
- Verify HTTPS compatibility and install the certifi package if necessary.
- Confirm the correctness of XPath or CSS selectors for image URLs.
- Ensure image URLs are in the correct format; log URLs for inspection.
- Handle redirects by setting REDIRECT_ENABLED = True.
- Check and set appropriate HTTP headers in your Scrapy spider.
- Adjust the CONCURRENT_REQUESTS setting to avoid server restrictions.
- Verify correct configuration of the ImagesPipeline.
- Inspect the downloaded images in the specified IMAGES_STORE directory.
- Implement exception handling in your spider to catch download errors.
