Website & System Logins

For rendering web pages located behind HTML forms and password-protected website directories into PDF files, the best practice is to forgo programmatic authentication and form submissions in favor of rendering the markup directly from local files or from HTML strings, as explained on the IronPDF login procedures resource page. However, in situations where accessing the source code of the web pages to be converted manually is cumbersome, time-intensive, or non-feasible, IronPDF can make rendering PDF content from these restricted areas easy and painless.

To convert web pages located behind password-protected directories, specify a set of valid network credentials for IronPDF's PDF Renderer to use with a ChromeHttpLoginCredentials object. Afterward, pass a reference to the ChromeHttpLoginCredentials along with the URL of the password-protected webpage to PdfDocument.renderUrlAsPdf:

// Import necessary packages
import com.ironpdf.*;

import java.nio.file.Paths;

public class PdfConverter {
    public static void main(String[] args) {
        // Define the URL of the password-protected webpage
        String restrictedUrl = "https://your-protected-website.com";

        // Create an instance of ChromeHttpLoginCredentials with valid user credentials
        ChromeHttpLoginCredentials loginCredentials = new ChromeHttpLoginCredentials("your_username", "your_password");

        try {
            // Render the URL as a PDF document using the specified login credentials
            PdfDocument pdf = PdfDocument.renderUrlAsPdf(restrictedUrl, loginCredentials);

            // Save the rendered PDF to a specified path
            pdf.saveAs(Paths.get("output.pdf"));
        } catch (Exception e) {
            // Handle potential exceptions, such as network errors or issues logging in
            e.printStackTrace();
        }
    }
}

// Import necessary packages
import com.ironpdf.*;

import java.nio.file.Paths;

public class PdfConverter {
    public static void main(String[] args) {
        // Define the URL of the password-protected webpage
        String restrictedUrl = "https://your-protected-website.com";

        // Create an instance of ChromeHttpLoginCredentials with valid user credentials
        ChromeHttpLoginCredentials loginCredentials = new ChromeHttpLoginCredentials("your_username", "your_password");

        try {
            // Render the URL as a PDF document using the specified login credentials
            PdfDocument pdf = PdfDocument.renderUrlAsPdf(restrictedUrl, loginCredentials);

            // Save the rendered PDF to a specified path
            pdf.saveAs(Paths.get("output.pdf"));
        } catch (Exception e) {
            // Handle potential exceptions, such as network errors or issues logging in
            e.printStackTrace();
        }
    }
}

• Comments and Explanation:
  • The ChromeHttpLoginCredentials object is used to store and pass authentication details such as username and password for accessing the secured webpage.
  • The PdfDocument.renderUrlAsPdf method is called to render the URL of the web page into a PDF file, using the provided login credentials.
  • The saveAs method is used to save the rendered PDF to a specific file path ("output.pdf" in this case).
  • Exception handling is included to manage errors that may occur during the PDF rendering or saving process, such as failed logins or network issues.
