Steps to reproduce the behavior in question

For Golang RPC section in rpc_client.go we have these lines of code:

func bodyFrom(args []string) int {
        var s string
        if (len(args) < 2) || os.Args[1] == "" {
                s = "30"
        } else {
                s = strings.Join(args[1:], " ")   // <------ here
        }
        n, err := strconv.Atoi(s)
        failOnError(err, "Failed to convert arg to integer")
        return n
}

I wonder if this supposed to be that way, because for any number of arguments greater than 2 we're getting a string of the form "xx yyy ... nnn" which leads to a conversion error in strconv.Atoi() call in any case.

Could you please clarify if this is intended behavior, or am I just being blind?

@humble1eenok you are welcome to submit a PR that modifies the tutorial. The idea is to read an integer to send to the (request-reply) server, nothing particularly creative.

The tutorials can be found in the website repo, and their executable versions are under rabbitmq/rabbitmq-tutorials. So any change should be applied to both repos.
