go get github.com/arienmalec/alexa-goThe alexa.Response struct implements the AWS Alexa Skill response, and contains a helper for simple speach responses.
The following is a minimal AWS Lambda implementing "Hello, World" as an Alexa skill in Go.
package main
import (
"github.com/arienmalec/alexa-go"
"github.com/aws/aws-lambda-go/lambda"
)
// Handler is the lambda hander
func Handler() (alexa.Response, error) {
return alexa.NewSimpleResponse("Saying Hello", "Hello, World"), nil
}
func main() {
lambda.Start(Handler)
}The alexa.Request struct implements the AWS Alexa Skill request, and contains some constants for locales and intents.
The following is a Lambda delivering localized content to users and handling multiple intents.
package main
import (
"github.com/arienmalec/alexa-go"
"github.com/aws/aws-lambda-go/lambda"
)
// DispatchIntents dispatches each intent to the right handler
func DispatchIntents(request alexa.Request) alexa.Response {
var response alexa.Response
switch request.Body.Intent.Name {
case "hello":
response = handleHello(request)
case alexa.HelpIntent:
response = handleHelp()
}
return response
}
func handleHello(request alexa.Request) alexa.Response {
title := "Saying Hello"
var text string
switch request.Body.Locale {
case alexa.LocaleAustralianEnglish:
text = "G'day mate!"
case alexa.LocaleGerman:
text = "Hallo Welt"
case alexa.LocaleJapanese:
text = "こんにちは世界"
default:
text = "Hello, World"
}
return alexa.NewSimpleResponse(title, text)
}
func handleHelp() alexa.Response {
return alexa.NewSimpleResponse("Help for Hello", "To receive a greeting, ask hello to say hello")
}
// Handler is the lambda hander
func Handler(request alexa.Request) (alexa.Response, error) {
return DispatchIntents(request), nil
}
func main() {
lambda.Start(Handler)
}Request/Response struct layout influenced by https://github.com/mikeflynn/go-alexa which was written before Go was an AWS Lambda native language.
