URL Decode node

#1

I tried decoding encoded URL’s with a recursive loop but it hit’s the sound barrier pretty early when processing bigger amounts of URL’s. Any option to include an URL decode node?

Yes - in fact it was supposed to be in the same release as the URL Encode node. Due to vacations it will be a couple of weeks before that is out there. In the interim, if you are happy venturing into a Java Snippet node, then the following should work:

try {
    out_Decoded = URLDecoder.decode(c_URL, StandardCharsets.UTF_8.name());
} catch (UnsupportedEncodingException e) {
    // Should never happen!
    out_Decoded = null;
}

(With an input column ‘URL’ and a new output column ‘Decoded’)

Ha, tried the Java node but I am not familiar with Java at all I must admit. getting “cannot be resolved” for URLDecoder, StandardCharsets and UnsupportedEncodingException. What did I missed?

Sorry, my over-simplification there…

At the top of the snippet box, under neath the line // Your custom imports you need to add the following lines:

import java.net.URLDecoder;
import java.nio.charset.StandardCharsets;
import java.io.UnsupportedEncodingException;

(You can get this automatically by hitting CTRL+Space once you are part-way through typing the java class name, e.g. URLDec, StandardChar and so on in the snippet - beware though, sometimes there is a choice!)

You should end up with something like:

(without the red underlining if you have set up the new output column and got the input column by double-clicking on it’s name in the Column List box)

hope that helps,

Steve

Thanks a lot for the tips! The autocomplete is very helpful to find the corresponding library to import.
