I am new with grails and on my web application i want to generate a random token with 15 characters length along with username. And tokens must be unique.
All characters from a-z and 0-9 can be use, but no special characters. I have tried to generate random token with
def generator = {String alphabet, int n -> new Random().with { (1..n).collec alphabet[ nextInt( alphabet.length() ) ] }.join() }} generator( (('A'..'Z')+('0'..'9')).join(), 9 )
but how can i append username infront of token like "JayKay586464ASDHH445"
How about this? The username holds the original username without the token, token is the 15 character token and uTok is the username with the token
def generator = { String alphabet, int n ->
new Random().with {
(1..n).collect { alphabet[ nextInt( alphabet.length() ) ] }.join()
}
}
def token = generator( (('A'..'Z')+('0'..'9')).join(), 15 )
def username = "JayKay"
def uTok = "${username}${token}"
println "==>${uTok}<=="
