How to convert Akka ByteString into String?

You can use the decodeString method like this:

scala> val x = ByteString("abcd")
x: akka.util.ByteString = ByteString(97, 98, 99, 100)

scala> x.decodeString("US-ASCII")
res0: String = abcd

Use

scala> val data = ByteString("xyz")
data: akka.util.ByteString = ByteString(120, 121, 122)

scala> data.utf8String
res3: String = xyz

see ByteString API,

or on github:

final def utf8String: String = decodeString(StandardCharsets.UTF_8)
