使用 Selenium/java 将网页保存为 PDF

Question

I'm trying to download the Page speed report from https://developers.google.com/speed/pagespeed/insights/ . Since it does not have a "Print" option, I need to save the webpage using selenium and java. What would be my options here?

Answer 1

Once you are one the Page speed page, you can use the below code to get the innerHTML.

String htmlContent = driver.findElement(By.tagName("body")).getAttribute("innerHTML");
System.out.println(htmlContent);

If you want to save this string to PDF file use the below mentioned library:

https://pdfbox.apache.org/

Once you have the mentioned library in your project. You can use the below code:

PdfDocument doc = new PdfDocument();
try {
  doc.load("your pdf file path");  
  // Write text at position (100, 100) on page 1
  doc.writeText(
    htmlContent,
    100, // x-coordinate
    50); // y-coordinate
   
  doc.save("your pdf file path");
  doc.close();
} catch (IOException | PdfException e) {
  e.printStackTrace();
}
