Extract key, value params from the resources of a url

Question

Hi Everyone I\'m working with the next url and I have to get the key-values params from this url the url could be in the next formats:

http://www.espn.com/watch/?gameId=

Answer 1

You could do something like this... I'm assuming that _ denotes that the next 2 elements are a key/value pair... I also changed the code to handle multile values in a query param (ie: k=a&k=b) which is perfectly valid.

def parseUrlStringToMap(URI uri) {
    if (uri.query) {
        uri.query.split('&')*.split("=").inject([:].withDefault { [] }) { m, v ->
            m[v[0]] << v[1]
            m
        }.collectEntries { k, v -> v.size() == 1 ? [k, v[0]] : [k, v] }
    } else {
        // I'm going to assume that key/values come after '_' paths
        def paths = uri.path.split('/')
        paths[paths.findIndexValues { it == '_' }.collect { (it+1)..(it+2) }].collate(2).collectEntries()
    }
}

println parseUrlStringToMap(URI.create('http://www.espn.com/watch/?gameId=1234&league=nfl&lang=es'))
println parseUrlStringToMap(URI.create('http://www.espn.com/fantasy/story/_/id/24664478/_/key/value/fantasy-soccer-la-liga-fantasy-transfer-market-matchweek-4'))

Answer 2

import java.nio.file.Paths

def u=new URL("http://www.espn.com/fantasy/story/id/24664478/fantasy-soccer-la-liga-fantasy-transfer-market-matchweek-4")
def p = Paths.get(u.getPath())

println p[2]
println p[3]

prints

id
24664478
