Downloading documents generated by Python

Questions
1

HI all,

I’m on NG-client 2023.03.x.

I have a Python script that generates Word documents. I would like my users to click a button and get the Word document as a download.
It does not seem to be possible to pass the binary data the script generates using application.executeProgram as this returns Strings.

Have anyone done integrations like this? Where do I get Python to save files so they can be read by the Servoy server?

Thanks,

Hi Christian,

As executeProgram returns a string, would it be possible to let Python return the doc as base64?

Then it would be pretty easy:

var _aBytes = utils.base64ToBytes(_sPythonB64)
			plugins.file.writeFile('myWordDocument.docx', _aBytes)

Otherwise, you should let Python write the file to a location which can be accessed by the application_server.
Then you can just read the bytes from that file and use the same writeFile command as above.

Hi Mark,

Thank you for confirming the approach, I seem to have a problem on the Python side, my data does not look Base64 encoded.

Got it working now. It turns out the binary data is padded when it is output from Python. There was a b' at the front and a ```
’

This caused the base64 conversion on the Servoy side to fail.

Thanks for your help, Marc.
