Best way to code this, string to map conversion in Groovy

Question

I have a string like

def data = \"session=234567893egshdjchasd&userId=12345673456&timeOut=1800000\"

I want to convert it to a map

Answer 1

Here's my effort, which initializes and fills the map in one go, and avoids the inject method which I personally find hard to follow:-

    def map = data.split('&').collectEntries {
        def kvp = it.split('=').collect { string ->
            string = string.trim()
            return string
    }
    [(kvp[0]): kvp.size() > 1 ? kvp[1] ?: '' : '']
    // the null check is almost certainly overkill so you could use :-
    // [(kvp[0]): kvp.size() > 1 ? kvp[1] : '']
    // this just checks that a value was found and inserts an empty string instead of null 
}
