cannot use function (type func()) as type in argument

Question

package main

import (
    \"log\"
    \"strings\"

    \"asl.com/asl\"
)

/*
Trivial service to demonstrate chaining service together
Message starts in originator,          


        

Answer 1

You are passing the function as an argument correctly but they do not match the expected signature. Change your functions to:

func UpperCaseHandler(md busboy.MessageDelivery) (interface{}, error} {
     s.Reply(MessageTest{strings.ToUpper(md.Message.(string))}, md.Delivery)
     return nil, nil
}

func RepeatHandler(md busboy.MessageDelivery) (interface{}, error} {
     s.Reply(MessageTest{strings.Repeat(md.Message.(string), 5)}, md.Delivery)
     return nil, nil
}
