How to pattern match in scala 2.13?

问题

I have the following regex, that I would like to pattern match in Scala 2.13.
The regex:

\/brokers\/ids\/\d{1,}$

The following string, that is going to be validate:

scala> ("echo dump" #| "nc localhost 32773" #| "grep brokers").!!
res2: String =
"       /brokers/ids/1
"

How can I do it in Scala 2.13?

回答1:

Scala 2.13 introduced interpolated string patterns, so you could avoid using regex and just do:

"/brokers/ids/1" match {
  case s"/brokers/ids/$ids" => ids //return 1
}
