Unable to download File From `data:` URL

[discover.selenium]

Please find attached test html file.

Print_PDF.html (27.2 KB)

Step 1: WebUI.openBrowser(‘C:\Users\XXX\Desktop\Print_PDF.html’)
Step 2: Click “Click Here” button
Step 3: Sleep(5000) & Manually Click the browser refresh button, since the PDF is not loading automatically.
Step 4: WebUI.switchToWindowIndex(1)
Step 5: println(WebUI.getUrl())
Step 6 Using Apache Commons IO, download the file from URL

String fileUrl = WebUI.getUrl()
String outputPath = "C:\\downloads\\test.pdf";
FileUtils.copyURLToFile(new URL(fileUrl), new File(outputPath));

Getting Error:

Reason:
java.net.MalformedURLException: unknown protocol: data

data URIs are not supported.

And don’t hold your breath, it was asked for 4 years ago.

URLs supplied to Katalon APIs MUST support data URIs

Example: the following should work: WebUI.navigateToUrl('data:text/html;charset=utf-8,<div>Katalon</div>') But KS (java.nio) issues the following error: Unable to navigate to ‘data:text/html;charset=utf-8, Katalon’ (Root cause: java.nio.file.InvalidPathException: Illegal char <:> at index 4: data:text/html;charset=utf-8,Katalon) which is silly – a colon is certainly NOT an illegal character when part of a Scheme, otherwise http:, https: etc should fail also… goodbye the interwebz.

There is nothing wrong with what you are doing – Katalon is at fault.

Thanks @Russ_Thomas … My query is, I just want to download the PDF file from URL. Is there a workaround.

In my AUT, I have url, that starts with blob, I didn’t face any issue with Katalon. I am look for a way to download the PDF file into my local system.

Since the URL Starts with blob or data, when I use Apache Commons IO, I am getting exception as below

Reason:
java.net.MalformedURLException: unknown protocol: data`

Below are few of the solution, I found on Internet. but I couldn’t succeed. Could you help,

Please have a look at my previous study a year ago:

Enabling Data URL in Katalon Studio

I have published a GitHub repository. Problem to solve In the Katalon Forum, there are a few posts that ask Katalon Studio to support Data URL. URLs supplied to Katalon APIs MUST support data URIs Katalon does not support Data URLs (rfc2397) I want to write a Test Case script like this: import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI WebUI.openBrowser("data:text/html,<h1>Hello, world!</h1>") Here the code fragment " data:text/html,<h1>Hello, world!</h1> " is cal…

I believe that there is a bug Katalon Studio’s keywords WebUI.openBrowser(String url) and WebUI.navigateToUrl(String url). Due to the bug, these keywords do not support Data URLs. But a small change can fix it. My research revealed how to.

I changed the topic title slightly

“From URL” -> “From data: URL”
