How to encode URL in Groovy?

groovy, url-encoding, urlencode

Solution

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"

Problem

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)
