Alexa SDK
alexa_sdk implements stucts corresponding to the Alexa JSON specification
along with helper functions for common uses of the Request and Response objects.
Usage
Simplest possible Alexa “Hello, World” skill:
extern crate lambda_runtime as lambda;
extern crate alexa_sdk;
use lambda::{lambda, Context, error::HandlerError};
use alexa_sdk::{Request,Response};
use std::error::Error;
fn my_handler(_req: Request, _ctx: Context) -> Result<Response,HandlerError> {
Ok(Response::simple("hello", "hello world"))
}
fn main() -> Result<(), Box<dyn Error>> {
lambda!(my_handler);
Ok(())
}A more complete skill, handling multiple locales and a slot:
extern crate lambda_runtime as lambda;
extern crate alexa_sdk;
use lambda::{lambda, Context, error::HandlerError};
use alexa_sdk::{Request,Response};
use alexa_sdk::request::{IntentType, Locale};
use std::error::Error;
fn handle_help(_req: &Request) -> Result<Response,HandlerError> {
Ok(Response::simple("hello", "to say hello, tell me: say hello to someone"))
}
fn handle_hello(req: &Request) -> Result<Response,HandlerError> {
let res = match req.locale() {
Locale::AustralianEnglish => Response::simple("hello", "G'day mate"),
Locale::German => Response::simple("hello", "Hallo Welt"),
Locale::Japanese => Response::simple("hello", "こんにちは世界"),
_ => if let Some(ref s) = req.slot_value("name") {
Response::simple("hello", (String::from("hello ") + s).as_str())
} else {
Response::simple("hello", "hello world")
},
};
Ok(res)
}
fn handle_cancel(_req: &Request) -> Result<Response,HandlerError> {
Ok(Response::end())
}
fn my_handler(req: Request, _ctx: Context) -> Result<Response,HandlerError> {
match req.intent() {
IntentType::Help => handle_help(&req),
IntentType::User(_) => handle_hello(&req),
_ => handle_cancel (&req)
}
}
fn main() -> Result<(), Box<dyn Error>> {
lambda!(my_handler);
Ok(())
}
