Downloading pdf file from internet

[henkkas]

Maybe anyone can help me with this problem.
I am trying to download a pdf file from a web address and store it on RPI. THis file is not secured, I think. I can normally download it my self from the web. But If I download the file, it seems it is empty.
I am confused. Here is the flow.

Check the output of the function node, particularly the filename. I think you might want
(new Date()).toString()
I don't know whether UTF8 string is the correct output format for the html node. It might be better as a binary buffer.

@Colin As always, you're right. Thanks very much for the help again !!!

@henkkas

As always, you're right.

If only that were true.

Did you have to change it to a buffer?

[henkkas]

Yes, indeed, @Colin , it is working perfectly now. As you might have seen, I needed that file to get elctricity tarifs from my distributor so I can update costprice in order to calculate energy costs. That's working now. Thanks!!!

greetings.
