Basic authentication does not work on first attempt

[arturbosch]

When I have following code fragments:

fun main(args: Array<String>) {
    embeddedNettyServer(8080) {
        get("/test") {
            authentication {
                println("authentication...")
                basicAuthentication("ktor") {
                    println("within basic ...")
                    authenticate(it)
                }
            }
            call.respond("Hello")
        }
    }.start(wait = true)
}

fun authenticate(user: UserPasswordCredential): Principal? {
    println(user)
    return users[user.name]?.let {
        if (it == user.password)
            UserIdPrincipal(user.name)
        else null
    }
}

I can call curl abosch@localhost:8080/test and get "Hello" prompt on first call. Following calls show me correctly that no password is specified and "Hello" is not returned.

Is it a bug or do I not understand how to use the authentication :) ?

It's a bug in the example, will update

You should do like this

route("/test") {
    authentication {
         basicAuthentication("ktor", ::authenticate)
    }

    handle {
        call.respond("Hello")
    }
}

or

route("/") {
    authentication {
        basicAuthentication("ktor", ::authenticate)
    }

    get("/") {
        call.respond("Hello, /")
    }
    get("/other") {
        call.respond("Hello, /other")
    }
}
