How to encode URL in Groovy?

GroovyUrlencodeUrl Encoding

Groovy Problem Overview

Is there a kind of URLEncode in Groovy?

I can't find any String → String URL encoding utility.

Example: dehydrogenase (NADP+) → dehydrogenase%20(NADP%2b)

(+ instead of %20 would also be acceptable, as some implementations do that)

Solution 1 - Groovy

You could use java.net.URLEncoder.

In your example above, the brackets must be encoded too:

def toEncode = "dehydrogenase (NADP+)"
assert java.net.URLEncoder.encode(toEncode, "UTF-8") == "dehydrogenase+%28NADP%2B%29"

You could also add a method to string's metaclass:

String.metaClass.encodeURL = {
   java.net.URLEncoder.encode(delegate, "UTF-8")
}

And simple call encodeURL() on any string:

def toEncode = "dehydrogenase (NADP+)"
assert toEncode.encodeURL() == "dehydrogenase+%28NADP%2B%29"
